1. Giant pandas are a vulnerable species famous for their consumption of large amounts of bamboo. Write a discrete-time matrix model of a giant panda population using the following assumptions. We are modeling only the female population. - - Pandas have three life stages: cubs, subadults, and reproductively mature adults. Cubs remain cubs for only one year. They have a mortality rate of 17%. - Pandas remain subadults for three years. Thus, about 33% of subadults mature into adults each year. - 28% of subadults die each year. - On average, adults give birth to 0.5 female cubs each year. - 97.7% of adults survive from one year to the next.
