Document Summary

Because we need to accommodate the growing population (carrying capacity). This is essentially just from population growth overtime. Population: a group of individuals of the same species living and interbreeding within a given area. Population ecology focuses on populations and how they change over space and time. Some variables to consider when thinking about population distributions. How resources are distributed in a habitat. Establishment are built and more people move there. Affect per capita birth or death rates in a way that is dependant on population density (i. e. , the effect is stronger/weaker depending on whether the population is dense/sparse) Factors affect per capita birth or death rates in a way that does not depend on. Can intensify the effect of density-dependant factors. If you live in a dense city you are more likely to be bit by a zombie. The level to which a transmissible disease is density-dependant vs. density-independent depends on how it spread between hosts.
