1. Introduction

The National Oceanic and Atmospheric Administration (NOAA) is focusing on the 5-year post-delisting monitoring process of the Humpback Whale (Megaptera novaeangliae) under the Endangered Species Act. The Humpback Whale is currently considered endangered in various regions, such as the Central America DPS, the Western North Pacific DPS, Arabian Sea DPS, and the Cape Verde Islands/Northwest Africa DPS, while it is labeled as threatened within the Mexico DPS. Consequently, the monitoring efforts will specifically target the Humpback Whale in the Mexico DPS as it is a threatened species, in alignment with the ESA criteria. NOAA will be the designated agency to which recommendations will be provided (NOAA Fisheries, n.d.). This monitoring plan draws from previous effective strategies such as the Eastern North Pacific Population of Gray Whales plan, emphasizing the necessity of tailored experimental designs and analysis methodologies for the humpback whale population. Taking into consideration the unique characteristics and habitat of the Mexico DPS, including breeding and feeding grounds in the North Pacific (Martinez-Loustalot et al., 2023), the monitoring plan's primary objective is to assess population size, health, genetic diversity, and threats. The plan places emphasis on accurate population estimation and various monitoring techniques like aerial surveys, genetic analysis, and acoustic monitoring, underlining the importance of data-driven conservation efforts post-delisting. Through a strategic monitoring design and analytical methods, the plan strives to provide crucial insights for effective management decisions and conservation actions.

1. Scenario Framework

The National Oceanic and Atmospheric Administration (NOAA) is a scientific agency within the United States Department of Commerce. Its main focus is on studying and understanding the conditions of the oceans, major waterways, and the atmosphere. NOAA's mission includes the conservation and management of coastal and marine ecosystems and resources, as well as the protection and recovery of endangered species under the Endangered Species Act (ESA) (NOAA Fisheries, n.d.). NOAA is particularly interested in the delisting of the Humpback Whale population of the Mexico Distinct Population Segment (DPS) to ensure the long-term survival of marine species and their habitats. The Humpback Whale (Megaptera novaeangliae) is a large baleen whale known for its acrobatic breaches and complex songs. The Mexico DPS is one of several distinct population segments recognized under the ESA, each with unique migratory patterns and breeding behaviors (Calambokidis et al., 2001). The Mexico DPS migrates annually between feeding grounds in the North Pacific and breeding grounds off the coast of Mexico.

Humpback Whales are known for their long migrations, traveling up to 5,000 miles between feeding and breeding grounds (NOAA, n.d.). They feed primarily on krill and small fish, using bubble-net feeding techniques to corral their prey. Breeding occurs in the winter months, with calves being born after an 11-12 month gestation period. The calves remain with their mothers for up to a year, during which time they learn essential survival skills. Monitoring efforts will be influenced by the whales' migratory patterns and breeding behaviors. Surveys will be conducted during peak migration and breeding seasons to ensure accurate population assessments. Additionally, ecological factors such as prey availability and habitat conditions will be monitored to assess the overall health of the marine ecosystem.

In order to effectively guide the post-delisting monitoring plan for Humpback Whales in the Mexico DPS, it is crucial to establish a robust Scenario Framework. This necessitates a thorough understanding of the regional dynamics, organizational imperatives, and ecological significance of the Humpback Whales in compliance with NOAA's mandate. The critical habitat for the Mexico Distinct Population Segment (DPS) of humpback whales encompasses approximately 116,098 square nautical miles (nmi2) of marine habitat in the North Pacific Ocean (NOAA Fisheries, n.d.). These areas, including sections within the eastern Bering Sea, Gulf of Alaska, and the California Current Ecosystem, play a vital role in supporting a diverse range of marine life and essential ecological processes for the humpback whale population. Humpback whales in this population typically breed and calve in the warm waters off the Pacific coast of Mexico, particularly around the Baja California Peninsula, and migrate to feeding grounds in the North Pacific, including areas off the coast of California, Oregon, and Washington (Martinez-Loustalot et al., 2023). These areas harbor diverse marine ecosystems, such as coral reefs, kelp forests, and deep-sea habitats, which are crucial for the feeding and breeding of Humpback Whales.

The proposed plan is focused on the regular assessment of humpback whale population size and trends. This will involve a comprehensive approach, including surveys and research to estimate the number of individuals and assess whether the population is increasing, stable, or declining (Evansen et al., 2021). To ensure accurate comparisons over time, consistent methods will be employed. Monitoring the birth and survival rates of calves is essential for understanding the population's reproductive success. This aspect encompasses the monitoring of mother-calf pairs and the frequency and success of breeding. In addition to this, it is crucial to monitor the health and genetic diversity of the population. This can involve the collection and analysis of genetic samples to understand the genetic health, diversity, and connectivity with other humpback whale populations. Health assessments may also include studying the physical condition and disease prevalence within the population. Furthermore, identifying causes of mortality and ongoing threats is essential. These threats include natural aspects such as predation and diseases, as well as human-induced threats like ship strikes, entanglement in fishing gear, pollution, and noise disturbance (Li et al., 2021). The plan will also assess the effectiveness of existing measures to mitigate these threats. Monitoring the implementation of laws and regulations protecting the humpback whale and its habitat, including international agreements and national laws, is also crucial.

1. Background

The background of the post-delisting monitoring plan for Humpback Whales in the Mexico DPS is rooted in the need for comprehensive assessment and sustainable management post-recovery. Drawing upon relevant literature, such as the monitoring plan for the Eastern North Pacific gray whale population as presented by the essential aspects of monitoring design, analysis, and key considerations are highlighted(Martinez-Loustalot et al., 2023). The framework for the monitoring plan integrates insights from previous research efforts to develop a robust strategy for monitoring population trends, health status, genetic diversity, and environmental threats. By examining the effectiveness of existing protection measures and addressing potential risks like ship strikes and pollution, the plan aims to ensure the continued recovery and conservation of the Humpback Whale population. This background serves as a foundation for structuring a monitoring plan that incorporates sound sampling techniques, analytical methods, and critical evaluation to guide conservation efforts effectively. Through this comprehensive approach, the plan will contribute significantly to understanding population dynamics and supporting conservation initiatives for the Mexico DPS humpback whales.

The monitoring plan for the Eastern North Pacific gray whale population, as outlined in the comprehensive 5-year plan for Research and Monitoring, emphasizes the significance of tracking population status to prevent extinction risks and ensure conservation efforts following delisting from the Endangered Species Act. The plan incorporates surveys, genetic sampling, and habitat monitoring to assess health indicators, reproduction rates, and human impacts. With a focus on key migration locations and employing experimental designs, the plan aims to evaluate the effects of reducing ship traffic on gray whale health and migration patterns through methods like aerial surveys and logistic regression modeling (United States. National Marine Fisheries Service. Gray Whale Monitoring Task Group et al., 1993). This structured approach underscores the importance of monitoring to prevent re-endangerment and informs conservation strategies with data-driven decisions. Drawing parallels between the monitoring plan for Eastern North Pacific gray whales and the monitoring plan for Humpback Whales in the Mexico DPS, both initiatives highlight the necessity of accurate population estimation, diverse monitoring methods, and comprehensive data analysis to ensure the protection and recovery of these iconic marine species. By leveraging insights from the gray whale monitoring plan, the post-delisting monitoring plan for the Humpback Whales of Mexico DPS can strengthen its monitoring design and analytical methods, aligning with best practices and scientific rigor to facilitate effective conservation strategies and long-term species recovery.

1. Recommendations

In devising a comprehensive monitoring plan for the Humpback Whales of the Mexico DPS, several key recommendations emerge. Firstly, it is essential to integrate a robust monitoring design that aligns with the goals of the post-delisting plan. Implementing a spatially-balanced random sampling approach, as highlighted in previous literature on marine mammal monitoringcan enhance the accuracy of data collection and population estimation. By adopting a BACI framework, the plan can effectively evaluate population trends, genetic diversity, health indicators, and threats with clear guidelines on sampling points allocation and methodology. Moreover, incorporating analytical methods such as logistic regression models and a Bayesian framework with a Gaussian copula can facilitate a nuanced understanding of population dynamics and threats post-delisting. These methods, coupled with adequate sample size considerations and replication strategies, can ensure the reliability and validity of the data collected for effective conservation management decisions. Integrating genetic monitoring, acoustic observation, and prey availability assessments(Martinez-Loustalot et al., 2023) can provide a holistic view of the Humpback Whale population, aiding in the development of targeted conservation strategies and real-time threat detection. Additionally, incorporating satellite tagging technology can offer valuable insights into the whales' movements, behavior, and habitat use, enhancing the effectiveness of conservation efforts(Ransome, 2022). Considering these recommendations, the post-delisting monitoring plan can serve as a comprehensive tool to safeguard the recovery and sustainability of the Humpback Whales in the Mexico DPS, aligning with the ESA requirements and NOAA conservation objectives.

A. Monitoring Design

The monitoring plan utilizes a Before-After-Control-Impact (BACI) design, which is carefully selected to effectively compare the population metrics and health indicators before and after delisting. It also takes into account control sites that are not affected by the same threats or conservation measures. This design is advantageous for identifying changes attributable to specific management actions or environmental changes (Evansen et al., 2021). Furthermore, sampling points will be assigned using a spatially-balanced random sampling approach to ensure an even distribution across critical habitat areas, reducing bias and enhancing the representativeness of the collected data. The critical habitat for the Mexico DPS covers approximately 116,098 square nautical miles in the North Pacific Ocean, including the eastern Bering Sea, Gulf of Alaska, and the California Current Ecosystem (NOAA Fisheries, n.d.). This comprehensive approach will provide valuable insights for the conservation and management of the Humpback Whale population in the Mexico DPS.

The monitoring program will involve several key components: population size and trends, birth rates and calf survival, health and genetic diversity, and mortality and threats. To estimate the population and assess trends, we will conduct annual aerial and ship-based surveys using line-transect sampling methods, supplemented by photo-identification and mark-recapture techniques annually (Martnez-Loustalot et al., 2023). We will monitor birth rates and calf survival by identifying and tracking mother-calf pairs through photo identification and genetic sampling, recording sightings frequency and calves' survival rates biannually during breeding and calving seasons. Biopsy samples will be collected every two years for genetic analysis and health assessments to assess the health and genetic diversity of the population, including genetic diversity, connectivity with other populations, and disease prevalence (Li et al., 2021). Lastly, we will document and analyze incidents of ship strikes, entanglement in fishing gear, pollution, and noise disturbance, and use satellite tracking to monitor movement patterns and high-risk areas annually to identify causes of mortality and ongoing threats.

The design criteria aim to monitor various aspects such as population size, trends, reproductive success, health, genetic diversity, and threats to ensure the continued recovery and stability of the Humpback whale population (Megaptera novaeangliae) in the Mexico Distinct Population Segment (DPS) over a five-year period following delisting under the Endangered Species Act (ESA). Sampling will be conducted at specific points and plots to achieve these objectives. Key sampling locations will include high-activity areas for Humpback whales, such as breeding grounds off the coast of Mexico, including Baja California and the Revillagigedo Archipelago, as well as feeding grounds in the North Pacific, such as the Gulf of Alaska and the California Current (Martien et al., 2021). A total of 40 strategic sampling points will be established, encompassing primary locations for breeding and feeding grounds as well as secondary locations for migratory periods.

To effectively monitor the breeding and feeding grounds of Humpback whales and their migratory corridors, an extensive sampling plan will be implemented, as outlined by Martien et al. (2021). The plan involves strategically situating 10 sampling points around the Baja California Peninsula to monitor breeding grounds, and distributing 20 sampling points across the eastern Bering Sea, Gulf of Alaska, and the California Current Ecosystem for feeding grounds. Additionally, 10 sampling points will be designated in migratory corridors to track movement patterns and potential threats. To ensure comprehensive data collection on whale presence, behavior, and potential threats, each sampling plot will cover an area of approximately 100 nautical square miles. Sampling frequency and timing will be well-defined: bi-monthly sampling of breeding grounds during the peak breeding season from December to April, bi-monthly sampling of feeding grounds during the peak feeding season from May to September, and monthly sampling during peak migration periods in October, November, March, and April. Each sampling session for breeding grounds, feeding grounds, and migratory periods will last a full two-week period (14 days) to allow for thorough data collection and to accommodate the variability in whale presence and behavior. This comprehensive sampling strategy is expected to provide valuable data for conservation efforts and population management.

To gather comprehensive data on the population size, distribution, and health of the Humpback whale population, a variety of sampling methods will be utilized. This will include conducting aerial surveys using drones and manned aircraft equipped with high-resolution cameras, LiDAR technology, and GPS tracking (Dawson et al., 2017). These aerial surveys will measure population size, distribution, and habitat use during each sampling event (Andriolo et al., 2006). The process will involve systematic transect lines flown over known Humpback whale habitats, and the collected photographs and LiDAR data will be analyzed to estimate population size and distribution patterns.

During each sampling event, our team will conduct boat-based surveys using standardized protocols to gather detailed data on individual whales. This will involve observing whale behavior, estimating population, photo-identification, and mark-recapture methods (Calambokidis & Barlow, 2004). We will measure variables such as individual identification, health assessments, genetic diversity, and prey availability. To approach whales for close observation and sample collection, research vessels equipped with GPS, hydrophones, and biopsy sampling tools will be used while following predetermined transect lines. We will employ photo-identification techniques to identify individual whales and collect biopsy samples for genetic analysis. Genetic sampling will be aimed at assessing genetic diversity and connectivity with other populations by collecting skin and blubber biopsies using crossbow darts, with a preference for noninvasive strategies if possible (Caroll et al., 2018). In addition, hydrophones will be used to record whale vocalizations and assess prey availability. Continuous passive acoustic monitoring using underwater hydrophone arrays will be conducted to measure whale presence and behavior, vocalization patterns, and anthropogenic noise levels (Hunt et al., 2013). Furthermore, Passive Acoustic Monitoring (PAM) devices at each sampling point will allow the recording of whale vocalizations and monitoring of presence in real-time at fixed locations within sampling plots.

The process of gathering and analyzing data will provide valuable insights into factors such as population size and distribution, health assessments, habitat usage, and acoustic data. To estimate population size and distribution, aerial and boat-based surveys will be conducted using mark-recapture and distance sampling methods (Dawson et al., 2017). Biopsy samples will be analyzed to study genetic diversity, stress hormones, and contaminants. Additionally, GPS data from boat-based surveys and LiDAR data from aerial surveys will be used to map critical habitats. Furthermore, acoustic recordings will be examined to identify whale vocalizations and assess the impacts of noise pollution. It is important to note that in order to participate in the surveys, all personnel involved in data collection must undergo rigorous training on all equipment and must pass a specialized exam, ensuring compliance with NOAA standard operating procedures (SOPs).

In the context of establishing a thorough monitoring strategy for the humpback whales inhabiting the Mexico DPS following their delisting, it is essential that certain criteria are established to ensure the efficacy of data gathering alongside its analysis. The selected methodological approach, such as the Before-After-Control-Impact (BACI) framework, will fundamentally influence the spatial arrangement of sampling sites, highlighting the significance of employing spatially-balanced random sampling to procure a sample that accurately reflects the entire population. The design criteria ought to specify aspects related to the quantity, positioning, as well as dimensions of sampling locations, while also addressing the sampling frequency necessary to effectively capture the variability over time (Martinez-Loustalot et al., 2023). The integration of sophisticated analytical techniques, including logistic regression models and a Bayesian framework, will facilitate the rigorous and efficient processing of data, taking into account crucial elements such as sample sizes, replication, and other covariates to support strong statistical conclusions. Such an approach guarantees that the monitoring plan is compliant with established scientific benchmarks, delivers actionable information to guide conservation efforts, and effectively mitigates potential obstacles to successful execution. The seamless inclusion of these design criteria considerations allows the monitoring strategy to proficiently oversee the recovery and sustained health of the humpback whale population within the Mexico DPS in the aftermath of the delisting process.

Guidelines dictating the allocation of sampling points across the landscape will be strictly followed, encompassing details related to quantity, geographical positioning, dimensions, and the frequency of sampling to maintain statistical integrity and impartial results. A multifaceted approach using aerial and marine surveys, genetic analysis, and acoustic monitoring will furnish the diverse datasets required for a complete understanding of population dynamics and potential threats arising post-delisting (Ferrante et al., 2019). This methodological strategy is designed to aid in the assessment of recovery trajectories, population steadiness, and the general ecological vitality, which is paramount for deploying effective conservation tactics and ensuring long-term sustainability.

B. Analytical Methods

Analytical methods hold a significant importance within the extensive monitoring strategy concerning Humpback Whales of the Mexico DPS subsequent to their delisting. Adopting a model-based methodology, the strategy amalgamates advanced techniques, encompassing logistic regression models and a Bayesian framework paired with a Gaussian copula, to scrutinize the collected data(Huard, 2006). Such analytical approaches are critical for dissecting population dynamics, genetic diversity, and various threats, thereby fostering well-informed conservation choices. It is pivotal to take into account elements like sample size, replication, and covariates during the data examination to mitigate bias and secure dependable outcomes. By integrating response variables alongside covariates within the analytical process, a comprehensive grasp of population heterogeneity and conservation requirements can be achieved(Martinez-Loustalot et al., 2023). The analytical protocols entail the appraisal of a priori models and hypotheses to gauge population recuperation, health, and stability following delisting. Consequently, these analytical methods seek to furnish NOAA with significant insights regarding the condition and advancement of Humpback Whales within the Mexico DPS, facilitating efficient conservation management and the enactment of sustainable recovery initiatives.

When designing an analytical approach for monitoring Humpback Whales in the Mexico Distinct Population Segment (DPS), we carefully considered various factors to ensure the effectiveness of the proposed method. After thoughtful deliberation, we decided to utilize a BACI (Before-After-Control-Impact) design, which allows for a comparison of population metrics and health indicators before and after delisting, while also including control sites for comparison (Evansen et al., 2021). The choice to use a BACI design is supported by Evansen et al. (2021) and is aimed at detecting changes resulting from specific management actions or environmental shifts. Additionally, our approach will make use of logistic regression models to analyze the collected data and assess various aspects such as population trends, reproductive success, genetic diversity, and threats to the humpback whale population.

The BACI design enables the comparison of population metrics and health indicators before and after delisting, while also incorporating control sites for comparison. The study by Evansen et al. (2021) strongly supports the effective application of the BACI design in identifying changes resulting from specific management actions or environmental shifts. Furthermore, this approach will employ logistic regression models to analyze the collected data and evaluate population trends, reproductive success, genetic diversity, and threats to the humpback whale population.In developing the model-focused monitoring strategy for Humpback Whales within the Mexico DPS, the chosen analytical technique incorporates a Bayesian framework for hypothesis verification and research planning, as outlined in the work of Alt et al. (2023). This technique is designed to accommodate multiple response variables of various types with covariates, using a Gaussian copula to account for correlations among responses. By fully implementing a Bayesian approach, our strategy aims to provide inference based on the joint posterior distribution of parameters, offering a robust analysis. Notably, the proposed technique aims to control the type I error rate in multiple testing situations, surpassing traditional approaches such as marginal regression models combined with Bonferroni-Holm adjustments, as demonstrated in simulation studies. Overall, the combination of a BACI design and logistic regression models, along with the adoption of a Bayesian framework, seeks to provide valuable insights into the population's status and to inform conservation efforts for this endangered species.

A strong post-delisting monitoring strategy for the Humpback Whale population in the Mexico Distinct Population Segment (DPS) requires careful consideration of sample size and replication. Adequate sample sizes are essential for accurately estimating population metrics, trends, and reproductive success (Andriolo et al., 2006). Utilizing aerial and boat-based surveys with mark-recapture techniques necessitates suitable sample sizes to capture the population's variability and dynamics over time (Calambokidis & Barlow, 2004). Pseudoreplication, spatial, and temporal replication should be managed meticulously to prevent biases and ensure the representativeness of monitoring data (Carroll et al., 2018). Implementing spatially balanced random sampling within important habitats and covering pivotal breeding, feeding, and migratory venues can effectively address the intricacies of the Humpback Whale population dynamics (Dawson et al., 2017). These elements underscore the need for methodological thoroughness and extensive sampling methods to support precise population assessments and preservation efforts for the Mexico DPS (Evansen et al., 2021).

Projected sample sizes for the monitoring plan focusing on Humpback Whales within the Mexico DPS need careful consideration and allocation of sampling locales within key habitat regions, such as breeding sites off the Baja California Peninsula and feeding zones in the eastern Bering Sea and Gulf of Alaska. Using a spatially balanced random sampling method ensures uniform distribution of sampling sites, reducing biases and enhancing data representativeness. Conducting bi-monthly aerial and boat-based surveys employing line-transect sampling techniques allows accurate estimation of population size and trends. Genetic sampling and health assessments are conducted biennially to evaluate the overall health and connectivity of the whales (Andriolo et al., 2006; Calambokidis & Barlow, 2004; Carroll et al., 2018). Additionally, hydrophone recordings for prey availability evaluation and acoustic monitoring enhance the monitoring plan's ability to recognize whale vocalizations and potential threats in real-time across crucial habitats (Hunt et al., 2013). This approach delivers comprehensive knowledge on the Humpback Whale population dynamics and health, ensuring the viability and recovery of this endangered species post-delisting.

When creating a monitoring protocol for Humpback Whales in the Mexico DPS, it is crucial to address concerns related to pseudoreplication, as well as temporal and spatial replication to obtain reliable data (Castellini et al., 2015). Temporal replication emphasizes the need to gather data across different time periods, while spatial replication requires data collection from different locations within the critical habitat to account for variability and differences. Implementing a spatially balanced randomized sampling strategy covering primary breeding, foraging, and migratory areas ensures that the monitoring plan accurately reflects population attributes and trends.

When monitoring Humpback Whales in the Mexico Distinct Population Segment, it's important to consider factors like population size, birth rates, threats, as well as habitat quality and prey availability. To ensure the whales' recovery and stability, we need to reduce errors and use advanced sampling techniques (Guidnard, 2022). Analytical models will assess these factors using statistical methods like logistic regression and mark-recapture techniques. The goal is to comprehensively represent the well-being of the Humpback Whale population while minimizing biases and repetition in the analysis (Guidnard, 2022). In selecting response variables and covariates for analyzing the Humpback Whale population in the Mexico DPS (Mategula et al., 2023), it's important to use a comprehensive method for effective monitoring. The response variables should include population size and trends, birth rates, calf survival, health, genetic diversity, mortality, and ongoing threats. Covariates, such as water temperature, prey availability, oceanographic conditions, and human activities, are essential for understanding population diversity and identifying key areas for conservation efforts. Considering these factors enhances the accuracy and precision of the analysis and provides valuable insights for conservation (Mategula et al., 2023).

In the analysis document focused on the Humpback Whale population in the Mexico DPS, it's important to classify variables as either explanatory or response. Response variables include population size, trends, birth rates, health assessments, genetic diversity, and mortality rates. On the other hand, covariates such as habitat characteristics, prey availability, pollution levels, oceanographic conditions, and anthropogenic threats should be considered as explanatory variables (Forkenbrock et al., 2004). This distinction helps analytical models capture complex marine ecosystem interactions, leading to conservation strategies for the Mexico DPS humpback whales.

As we develop a monitoring plan for the Humpback Whales in the Mexico DPS, we are considering various hypotheses and models for analysis to ensure effective conservation efforts. These models are designed to address crucial factors such as population size, trends, reproductive success, genetic diversity, and threats. One of the models under consideration is the population dynamics model, which aims to estimate population size and analyze trends over time using statistical tools such as capture-recapture methods (McCallum, 2008). Another model focuses on reproductive success and calf survival rates, utilizing photo-identification and genetic sampling techniques to monitor breeding success within the population. Furthermore, a model will be implemented to assess the health and genetic diversity of the population, employing genetic analysis and health assessments from biopsy samples. Lastly, a model will explore mortality and threats, aiming to assess the impacts of various threats such as ship strikes, fishing gear entanglement, and pollution on the humpback whale population in the Mexico DPS, and to identify key factors affecting their population (McCallum, 2008).

In formulating a preliminary or priori list of models and hypotheses for the monitoring strategy of Humpback Whales specific to the Mexico DPS, it is important to consider various aspects. The focus should primarily be on estimating population size and trends to ensure the stability and growth of the Humpback Whale population after delisting. This involves considering different models that illustrate population dynamics, including birth and mortality statistics, as well as those that assess genetic diversity and overall population health (Fisher et al., 2019). These models can be refined to address specific research questions and strengthen the depth of the monitoring plan, drawing from various areas of study. Insights about sampling locations and data collection methodologies are valuable in developing robust hypotheses that align with the defined monitoring goals, facilitating an effective method for extracting significant data from the collected samples. Furthermore, models examining the impacts of human activities and natural threats on the Humpback Whales can provide valuable insight into conservation approaches (Fisher et al., 2019). Therefore, creating a comprehensive preliminary list of models covering various aspects of population dynamics is crucial for formulating a robust monitoring strategy.

In developing a post-delisting monitoring plan for the Humpback whale population within the Mexico Distinct Population Segment (DPS), it's important to consider several factors to ensure its effectiveness. Kotronis et al. (2024) emphasizes the need to integrate cost analysis within SysML models for design tradeoff scrutiny, highlighting the importance of understanding the financial implications of monitoring approaches. Utilizing entities and functions related to costs in the SysML cost profile can be valuable for evaluating budget limits and resource distribution for sustainable monitoring efforts.

Additionally, Makena Faith Benson et al. (2023) stresses the significance of monitoring teaching and learning processes in deploying competency-based curriculums, emphasizing the need for ongoing assessment and modifications to enhance outcomes. One crucial aspect of the monitoring plan involves precise monitoring of population size and trends, which includes rigorous methodologies such as aerial and boat-based surveys to gather reliable data on whale abundance and dispersion. Furthermore, monitoring reproductive success to ensure sustained viability involves careful observation of calf production and survival metrics through non-invasive techniques aimed at reducing animal stress (Cates, 2021). Assessing the health and genetic diversity of the population calls for meticulous sampling strategies to evaluate genetic health, diversity, and connectivity, all while aiming to minimize disturbance to the whales. By addressing these multifaceted concerns, the proposed analytical approach could effectively oversee the Humpback whale population in the Mexico DPS and further their conservation efforts.

In evaluating the analytical methods utilized for the Model-Based Monitoring Plan, it was necessary to assess their appropriateness and effectiveness. According to Raza et al. (2019), the use of computational models provided a structured framework for analyzing news events, offering multiple dimensions for thorough examination. This news-focused model-based approach provided perspectives for monitoring and scrutinizing large amounts of information, proving to be adaptable and comprehensive. Additionally, McClure et al. (2020) emphasized the critical role of artificial intelligence tools in project management, stressing the significance of integrating hybrid intelligence and neural networks in decision-making processes. When examining excluded or discarded analytical methods, the Humpback Whales monitoring plan within the Mexico DPS specifically focused on avoiding invasive techniques to protect individual whales and maintain ethical monitoring standards post-delisting. This integrative approach aimed to uphold scientific rigor and ethical principles in monitoring activities, in line with the broader goal of sustainable conservation and population oversight.

1. Plan Considerations

To maintain data quality, important considerations include using proper sampling techniques, clear data collection protocols, and rigorous analytical methods (Wagner & Henzen, 2022). Consistent protocols and procedures across all evaluations help reduce biases and errors. Quality assurance measures need to address potential sources of variability and inaccuracies in data collection, such as observer bias or equipment inconsistencies, to maintain the integrity of the findings. Emphasizing data quality assurance helps strengthen the reliability of the results, promotes comparability over time, and supports evidence-based decision-making (Stanford Environmental Law Society, 2001). Validating data, comparing laboratory outputs, and verifying processes can further establish the credibility of the collected data. Continuous monitoring of data quality is essential for promptly identifying and correcting any discrepancies, enhancing the overall quality of the data.

In order to develop a comprehensive Data Analysis Plan for monitoring the Humpback Whale population post-delisting in the Mexico Distinct Population Segment (DPS), it is crucial to establish a robust analytical framework to extract valuable insights from the collected data. The proposed plan should encompass model-oriented components and statistical methodologies, aligning with the field observations to ensure the suitability of the selected analysis strategies (Zhang et al., 2021). Considerations such as sample size and replication approaches are essential to guarantee the statistical robustness of the analysis, while also addressing potential complexities such as pseudoreplication. Incorporating both temporal and spatial replication for thorough data examination is also important. Additionally, a detailed list of response variables and covariates to be included in the analysis will enhance the evaluation process regarding population trends, genetic diversity, and post-delisting threats (Tonachella et al., 2012). Exploring various models and hypotheses will further enrich the analytical framework, providing a deeper understanding of the Humpback Whale population dynamics in the Mexico DPS area (Stanford Environmental Law Society, 2001). Careful consideration and critique of the monitoring strategies will help identify potential limitations, logistical challenges, and budget constraints to ensure the strength and efficacy of the Data Analysis Plan (Stanford Environmental Law Society, 2001).

In the field of studying Humpback Whales in the Mexico DPS, the application of statistical software plays a crucial role in analyzing data gathered through various monitoring techniques (West et al., 2022). This software provides robust tools for data analysis, population dynamics modeling, and assessing the impacts of potential hazards on the whale population. By utilizing statistical software, researchers can efficiently manage and interpret large datasets, leading to valuable insights about the health, genetic diversity, and general well-being of the humpback whale population following their delisting. Furthermore, the software enables the use of advanced analytical strategies such as logistic regression models and Bayesian frameworks to identify trends, patterns, and correlations within the dataset. Rigorous data analysis through statistical software enhances the precision of population estimates, evaluates genetic variability, and reveals emerging threats, all of which contribute to evidence-based conservation strategies and management decisions (McCarthy et al., 2008). As technological advancements continue, the use of statistical software will be indispensable for monitoring efforts post-delisting for the humpback whales of the Mexico DPS, highlighting the importance of employing cutting-edge tools to strengthen conservation initiatives.

In order to effectively monitor the Humpback Whales in the Mexico Distinct Population Segment (DPS), it is important to incorporate hypothesis testing into analytical methodologies. Hypothesis testing provides a structured way to evaluate the significance of observed data while addressing research questions rigorously. This monitoring strategy aims to conduct comprehensive analysis and draw solid conclusions by clearly defining null and alternative hypotheses related to population dynamics, health metrics, genetic variability, and potential threats. The use of statistical hypothesis testing techniques such as logistic regression models and Bayesian methodologies with a Gaussian copula allows for the assessment of relationships among different variables in relation to the status of the humpback whale populations after they have been removed from the endangered species list (Ma et al., 2021). The plan should explicitly outline hypotheses, set relevant significance thresholds, specify response variables and covariates, and consider factors such as sample sizes and replication to ensure consistent and reliable results. Making decisions based on data and accurate estimations is crucial for monitoring the recovery and conservation of the humpback whale population.

Upon completion of data collection, it is essential to engage in the significant phase of interpreting the results within the monitoring strategy for the delisted Humpback Whales in the Mexico DPS. This will involve using logistic regression models alongside a Bayesian framework utilizing a Gaussian copula to thoroughly examine demographic trends, genetic variety, health status, and existing threats (Murray et al., 2013). The focus of the result interpretation will be on achieving precise estimations by appropriately determining sample sizes and ensuring repetition, critical for avoiding biased or unreliable outcomes. Effective management of spatial and temporal data is crucial for extracting meaningful insights regarding the recovery and conservation status of the Humpback Whale population. The analytical methodology will be enhanced by integrating genetic monitoring, line-transect surveys, evaluations of prey availability, and acoustic monitoring to provide a comprehensive perspective of the species in the post-delisting context (Stanford Environmental Law Society, 2001). Additionally, the interpretation stage will encompass enhancing monitoring efficiency through approaches such as Maximum Entropy Sampling, facilitating improved conservation initiatives and a better understanding of population diversity (Fampa & Lee, 2022). The interpretation of outcomes is crucial for guiding prospective conservation endeavors and ensuring the sustainable resurgence of whales.

When developing the monitoring strategy for the Humpback Whales in the Mexico Distinct Population Segment (DPS), we carefully considered various factors to ensure the effectiveness and feasibility of the proposed design and analytical methodologies. Key considerations included compliance with the Endangered Species Act (ESA) requirements for post-delisting monitoring, which emphasized the importance of accurate data collection and robust analysis methods. We thoroughly examined alternative strategies, taking into account logistical limitations and budgetary constraints, to identify the most suitable monitoring approach. The chosen design focused on using spatially-balanced random sampling to ensure comprehensive coverage of the whale population across their crucial habitats, thereby enhancing the reliability of the collected data (Benedetti, 2017). By employing a Bayesian analytics framework alongside logistic regression models, the strategy aims to provide detailed insights into population dynamics, genetic variability, and potential risks after delisting, aligning with the goal of sustainable recovery and conservation efforts (United States. National Marine Fisheries Service. Gray Whale Monitoring Task Group et al., 1993). This thoughtful and iterative planning process resulted in a well-considered methodology that balances scientific rigor with practical application for successful post-delisting monitoring of Humpback Whales in the Mexico DPS.

Increasing the effectiveness of post-delisting monitoring plans for Humpback Whales within the Mexico DPS is crucial, and alternative monitoring approaches play a significant role in achieving this. By embracing innovative strategies that surpass traditional methods, we can enhance data collection and analysis. This includes the incorporation of spatially-balanced random sampling (Benedetti, 2017), acoustic monitoring for real-time threat detection, and genetic analysis to gain a comprehensive understanding of population dynamics, overall health, and genetic variability. The application of Maximum Entropy Sampling techniques (Fampa & Lee, 2022) can enhance monitoring effectiveness and enable a more efficient allocation of available resources, ultimately leading to more accurate estimations. Additionally, leveraging advanced technologies such as aerial photogrammetry, in conjunction with interdisciplinary partnerships (Cheeseman, 2023), can significantly improve data quality and enhance our understanding of the changes experienced by whales following their delisting. There's a clear focus on non-invasive methods, such as surveys conducted via aerial and vessel means (Cheeseman, 2023), reflecting the need to minimize disturbances to whale populations while still gathering crucial information. These alternative monitoring strategies have the potential not only to refine conservation efforts, but also to positively contribute to the longevity and preservation of Humpback Whales within the Mexico DPS.

The monitoring plan for Humpback Whales in the Mexico Distinct Population Segment (DPS) has both advantages and disadvantages. The focus is on collecting extensive data about population trends, health status, genetic diversity, and potential risks following delisting. This is done using a model-oriented method that integrates logistic regression models with a Bayesian framework using a Gaussian copula for data examination. The goal is to provide precise estimations by considering sample size and replication, managing both spatial and temporal datasets to achieve unbiased outputs (Yaez-Arenas, et al., 2014). This methodology allows for a comprehensive evaluation of recovery and stability, which is crucial for conservation efforts. However, despite the analytical strength and insights provided by this approach, challenges remain. It is essential to maintain adequate sample sizes and replication to ensure reliability and statistical robustness (Kwakkel & Pruyt, 2013). Balancing these advantages and disadvantages will be crucial for the successful implementation of the monitoring strategy and the effective oversight of Humpback Whale populations within the Mexico DPS.

In developing a comprehensive monitoring strategy for the Humpback Whales within the Mexico distinct population segment (DPS), it's essential to address logistical and financial constraints to ensure the effectiveness of the proposed post-delisting supervision (Smokorowski et al., 2017). Recognizing the challenges associated with remote habitat accessibility, survey coordination, and budget considerations, the establishment of an effective monitoring framework, such as a Before-After-Control-Impact (BACI) model combined with spatially balanced random sampling methodologies, is crucial for robust data collection (Smokorowski et al., 2017). Strategic decision-making on sampling techniques, replication efforts, and resource allocation for survey logistics is necessary to address potential logistical barriers and financial limitations, while refining analytical techniques to enhance data analysis and accurate assessments of population dynamics and threats (Martinez-Loustalot et al., 2023). Aligning monitoring efforts with practical realities of logistical and budgetary constraints is paramount for the successful implementation of the monitoring initiative, ensuring scientific integrity within available resources.

Adaptive management tactics play a significant role in the post-delisting monitoring initiative for Humpback Whales in the Mexico Distinct Population Segment (DPS). By incorporating principles of adaptive management, which involve continuous learning and the ability to be flexible, the monitoring plan can adapt to new information and changing conditions (Westgate et al., 2013). This approach allows for adjustments in sampling techniques, analysis methods, and conservation efforts based on current data and feedback. Establishing a strong adaptive management framework enables the National Oceanic and Atmospheric Administration (NOAA) to make well-informed decisions regarding population recovery, health assessments, and the mitigation of threats to the Humpback Whales in the Mexico DPS. Through ongoing evaluation of monitoring results and adaptive responses, the plan aims to strengthen the effectiveness of conservation strategies, support sustainable recovery, and effectively address emerging challenges (Martinez-Loustalot et al., 2023). This adaptive approach not only improves the accuracy of population monitoring but also contributes to overall conservation efforts for the long-term well-being of the Humpback Whale population in the Mexico DPS.
