The factors that affect the species diversity?
-Invasive species- When a new species that is not native moves into an area, it often won't have natural predators and can thus survive better than natives. They take over, and lower diversity levels by killing off other species -Keystone species- a keystone species is a species which many others in the food chain rely on, if the keystone species has a problem or decrease in population the diverersity of the population will also decrease. - Availability of resources- For instance food, shelter, nutrients, notice that rain forests which are abundant in rain forests show much diversity, while a tundra shows very little diversity. - Stability of the community- for instane, tempreture shifts will cause a decrease in diversity because certain species have a small range of tempreture that they can live in. This is why coral reefs are decreasing in diveristy, they are very limited in teh tempreture they can live in. I wouldn't agree that natural selection affects diversity levels as it is present at all times, in every ecosystem and does not fluctuate.
