Genetic Drift

Concept Check: How does the bottleneck effect undermine the efforts of conservation biologists who are trying to save species nearing extinction?

Context - The study aims to test the role of priority effects in fruit fly communities. I tested whether the timing of one species arriving at a particular site causes any alteration to the environment, making it more or less desirable for a second species to come.   What does the data suggest? What does anova P = .45 means?
Plz answer shortly.    You are a conservation biologist working on a captive breeding program for black-footed ferrets. You have the budget to establish either two populations of 100 ferrets each, or 10 populations of 20 ferrets each. Which approach do you think is most likely to succeed, and why?
Movement and Population Genetics: Metapopulation models focus on the BIDE (birth, immigration, death, emigration) dynamics, colonization and extirpation.  Explain how these relate to genetic bottlenecks, and explain why metapopulation models have a hard time predicting such events? Why is the island biogeography model a strong example of metapopulation dynamics?
