BIOL 4253 : Review Questions For Exam 2 Answered
Document Summary
Smaller demes are more likely to go extinct, especially if they are isolated with little gene flow: be able to estimate population size using mark recapture methods. Social animals or plants reproducing asexually are clumped, aggressive animals or plants competing for soil moisture are uniform, and random is the null model. Give an example of each: give several examples of how dispersal limits distributions. You could experimentally determine ideal conditions in the lab, then find the right spots in the field to search. A cohort life table makes fewer assumptions about lx and mx: give examples of the three basic survivorship curves. If lx and mx remain constant through time, the relative abundances of the age classes will stabilize: be able to use the the equation for exponential growth to project population sizes and calculate doubling times. N20 = 100 x e (0. 4 x 20) = 100 x 2981= 298,096.
