Question

Are the following statements True or False:

An evolutionary stable strategy is one that occurs at a 50:50 ratio with another strategy

Ideal free distribution predicts a linear positive relationship between the amount of resources in a habitat and the number of individuals living there.

Strong conspecific cuing will improve how well animal distributions fit the predictions of ideal free distribution

Marginal Value Theorem predicts that the longer it takes to find a new patch, the less time individuals should spend foraging in each patch.

Answer 1

First statement is FALSE

An evolutionary stable strategy is the one which if adopted by a population in given environmental condition, it cannot be invaded by any other strategy. So this is a false statement that evolutionary stable strategy is one that occurs 50:50 with other strategy

Second statement is TRUE

Ideal free distribution in a way depicts the relation between individuals aggregating in an area and the resources patches in that area. If one area has double the resources then the number of individuals aggregating there will also be double.

Third statement is FALSE

Ideal free distribution requires that animals can accurately perceive density dependant habitat quality. So strong conspecific cuing will interrupt the ideal free distribution

Fourth statement is FALSE

According to marginal value theorem, if it is longer to find a new patch the individuals should spend longer time for foraging in each patch
