Question

Explain how could ongoing evolutionay change affect species distribution

Answer 1

Stressful environmental conditions can be definedas those that lead to a sharpreduction in fitness in populations. That is, when changed environmental conditions cause a drastic reduction in reproductive output,and when persistence of the conditions leads to permanent damage,these conditions constitute an environmental stress. Physical stresses that are encountered rarely in populations—suchas periods of drought or extreme cold—or that are encountered by a minority of a species—such as in populations that arelocated at distribution bordersor are exposed to local chemical stresses arising from human activities—can, through their director indirect effects, lead to marked reductions in the size of populations (Glynn 1988,Hoffmann and Parsons 1991) and to repeated cycles of colonization and extinction (Andrewartha and Birch 1954).

Answer 2

ANSWER
..........

1. WHEN THIS IS CHANGE THEN THE ENVIRONMENT CONDITION CAUSE IN REPRODUCTION OF THE OUTPUT

2. THIS IS THE CONSIST OF THE ENVIRONMENT TRESS
