Which of the following strategies would most rapidly increasethe genetic diversity of a population in an extinction vortex?(A) Establish a reserve that protects the population’s habitat.(B) Introduce new individuals transported from other populations of the same species.(C) Sterilize the least fit individuals in the population.(D) Control populations of the endangered population’spredators and competitors.
An extinction vortex describes
a) changes in a population’s gene pool that lead to a loss in fitness across time.
b) a species ability to adapt to changes in their environment.
c) the continuous series of extinctions caused by competition between species.
d) a population that has a reduction in fitness because it cannot escape a Hardy-Weinberg Equilibrium.

What's the birth rate for this population? Is this proving to be a suitable habitat? (Two answers) a) Yes, this is a suitable habitat. The birth rate is higher than the death rate. b) No, this is not a suitable habitat.

(a) The first class postulates the existence of a positive feedback between local abundance and the regional distribution of a species. (b) Species that occur in large number across many localities will be more likely to maintain their wide distribution and high abundance. (c) Consequence of positive feedback is that there is no dichotomy. (d) The consequence of positive feedback is that there is dichotomy, species will be either widespread or abundant or they will be restricted and scarce. This division helps in the knowledge and in turn helps to categorize them accordingly as restricted or widespread species.arrow_forward
