Question: Summarize how new species can arise by explaining the differences between allopatric and sympatric isolation. Give a real example of when allopatric speciation has been observed and when sympatric speciation has been observed.
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?
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?

Enter DiegoLinks to an external site., who fathered 800 offspring to save his species (the Española Galapagos tortoise). The population now sits at 2,000 tortoises and Diego is going home. As we saw last week, population size is important. Ideally, this means you started with a lot of genetically diverse founders, but of course that isn’t always the case. In the case of the Española Galapagos tortoises it was 12 females and 2 males. So, often you have to grow your population to stabilize it and ensure there isn’t an unacceptable loss of genetic diversity over time, even if that genetic diversity is low. If you think back to the math from last week and do a little not so fancy algebra, you can see that genetic deterioration occurs at a rate that is the inverse of genetic retention, which you probably remember is 1- (1/2Ne) The above…arrow_forward
