Document Summary

Be able to describe and understand exponential and logistic models of population growth. In exponential growth, a population per capita (per individual) growth rate stays the same regardless of population size, making the population grow faster and faster as it gets larger. Yeast growth levels cut off as the population hits the limit of the available nutrients. Meaning that fuel source would eventually run out and wastes might reach toxic levels. Lecture 2: groups and populations: continuous: reproduction occurs year-round, this occurs if a population show continuous breeding season. They never depend on parameters like season, food, climate for breeding. Here the population depends of instantaneous per capita rate of growth. Become familiar with demographic rates and how they are measured: variables which drive changes in population size, birth, death, emigration (number leaving population) Imbalanced initial age structure age and number cycles.
