At the end of this lab, students should know...
As the size of a habitat increases, extinction risk generally decreases due to greater population sizes.
An endemic species is one that exists in one habitat and nowhere else.
Immigration and extinction rates become balanced at the point of dynamic equilibrium.
With increasing proximity to the mainland, the colonization rate of an island increases, as it is easier for organisms to disperse or travel over smaller distances.
Corridors allow organisms to travel more easily between separated habitat areas, facilitating immigration to promote species survival.
