BIOL2010 Lecture Notes - Lecture 11: Christmas Bird Count, Bald Eagle, Malthusian Catastrophe
Document Summary
Exponential population growth: what determines whether the curves go up sharply or steadily the r of the per capita rate of increase, small r has slower growth and large r has faster growth. Increase in suitable habitat because of increase in suburbia: bald eagle, det has negative impact that caused shells to lay thinner eggs, det was banned and they were not allowed to be hunted, population increase was exponential. In the beginning there is exponential growth, but as you approach the carrying capacity, the growth gets smaller and smaller: when you reach carrying capacity, the growth stops and the line stays flat. Limits to population growth slow population growth down. Population dynamics eggs: changes in populations through time and space, metapopulation dynamics, population of populations, patches in the metapopulation are connected by migration to and from different patches. Lecture 9 contd slides and lecture 10 slides.
