The process of natural selection can be sped up immensely by strong population pressures. Population pressure is a circumstance that makes it harder for organisms to survive. There's always some kind of population pressure, but events likefloods, droughts or new predators can increase it. Under h...

I learned that biodiversity is endangered by environmental changes, illegal poaching, and tourism. People depend on some of the plants abd animals in the that maje up the ecological environment. For example, one-fourth of the prescriptions is made up of some of the plants.Finally, humans benefi...
Umbrella species are species that are selected as representatives of their ecosystem when conservation plans are being made. By protecting these organisms, other species that are a part of their ecosystem will also benefit under the same conservation "umbrella." An umbrella species is usually chosen...

Genetic drift is now recognized as one of the major causes of evolution, although its results are usually random rather than adaptive. Chance events operating in small populations can have huge effects on gene frequency. Imagine, for instance, an isolated population of a very rare, endangered ...

Biodiversity:The wide range of organisms—plants and animals—that exist within any given geographical region. Boreal:Located in a northern region. Canopy:The "covering" of a forest consisting of the highest level of tree branches in the forest. ...
This is one of the many statuses given by IUCN like endangered, extinct, rare, etc. They have small population sizes, less genetic variability among individuals, and more vulnerability to get endangered and extinct. The chances of these species to recover after ecological disasters are very bleak...
