Mollusk species with higher metabolic rates are more likely to go extinct than those . Genetic variation allows species to adapt to changes in the environment. With fewer breeding pairs, genetic variation shrinks.Monoculture, the agricultural method of growing a single crop, can also reduce genetic variation. 1. Gap analysis is a biogeographical technique of mapping biological diversity and endemic species to find gaps between protected areas that leave endangered habitats vulnerable to disruption. More importantly, all living species, including people, depend on other species for survival. Many scientists consider Bd, The long-term viability of species and populations is related to their potential to migrate, reproduce, and adapt to environmental changes. e) Estimate the rate at which the person gains entropy. Why aren't zoos a good place to preserve whales, bats, and some reptiles? You can see r- and K-selected strategies clearly by looking at different organisms within a phylogenetic group, such as the mammals. Groups of species that have a tendency to inbreed usually have little genetic variation, because no new genetic information is introduced to the group. Weight.
