How would a stochastic event lead to the extinction of population? What are the differences of the static and cohort method of estimating parameters of a life table? When would the net reproductive rate, reflect the geometric growth of a age structured population? What is a metapopulation and when would somoene model a population as such?

1. The effects of disease in a population would be considered density dependent. True False 2.You discover a new species of salamander and after watching it through mating season, you determine that females lay between 1000-1500 eggs at a time on average. Based on this information and your knowledge of life history traits, you predict that the species also: A. has low levels of parental care. B. has a low risk of mortality at a young age. C. reaches sexual...
