2. Here is one way in which nature regulates the size of animal populations: high population density attracts predators, which remove a higher proportion of the population than when the density of the prey is low. One study looked at kelp perch and their common predator, the kelp bass. The researcher set up four large circular pens on sandy ocean bottoms off the coast of southern California. He chose young perch at random from a large group and placed 10, 20, 40, and 60 perch in four pens, allowing bass to swarm in, and counted the perch left after two hours. He did this four times for each pen. Computer output from the least squares regression analysis on the perch data is shown below: Predictor Coat Stdev. t-ratxo p Constant 0.12049 0.09269 1.30 0.215 Perch 0.008569 0.002456 3.09 0.004 S ; 0.1386 R-Sq = 46.5' R-Sqtadjl & 42.7' a.)
