78 views3 pages

Document Summary

We need to protect them from extinction: some reserves may not support viable populations of some species, species roam widely. 3: identify the factors that make small populations vulnerable to extinction, and apply this knowledge to suggest management strategies for those populations to mitigate the risk of extinction. Factors that make small populations vulnerable to extinction are. 1: loss of variation in the gene pool. Due to a small population, there is continuous inbreeding, which results in many of the individuals being related. This reduces the gene pool in the population, such as the black robin in new zealand. Small genetic variation, a simple illness can wipe out the whole population. Continuously changing environments will result in animals being stressed. Animals that are constantly stress, can suffer from illnesses and lack of feeding. Both of these effects will reduce reproductivity in the animal, because all its energy is going into trying to relieve stress.
