This stable ecosystem is called the climax community. This means that under the current climate conditions, little to no changes are occurring. Most diagrams depict this as a forest, though the Sahara Desert has remained unchanged for almost five thousand years. Primary succession occurs when there is only rock in the area. Secondary succession requires less time because there is a soil present. Often a natural disaster wipes away the living organisms leaving only soil. A keystone species is depended upon by other species in the ecosystem such that if it were removed, the ecosystem would undergo dramatic changes. An indicator species is one that reflects the health of its ecosystem. ]]> 2021-05-24 03:58:36 UTC https://padlet.com/1090185/63hdfr9mnrj1l3p9/wish/1552518309 Natural Disruptions to Ecosystems 1090185 https://padlet.com/1090185/63hdfr9mnrj1l3p9/wish/1552518606 Changes such as lightning strikes, hurricane season, volcanic, ocean levels changing. animals also migrate when natural disruptions happen. resistance measures how much an ecosystem changes after disruption. resilience is the measure of how quickly the ecosystem can ‘bounce back’ from the disturbance. It is ecosystem recovery time.

Populations decrease due to too much or too little of an environmental factor and it leads to stress]]> 2021-05-24 03:58:57 UTC https://padlet.com/1090185/63hdfr9mnrj1l3p9/wish/1552518953 Island Biogeography 1090185 https://padlet.com/1090185/63hdfr9mnrj1l3p9/wish/1552519171 After an island is formed, it will soon be inhabited by organisms. The size and distance from the mainland affect the number of species that the island can support. As extinction increases, immigration decreases. The point of intersection is the equilibrium for the island. Islands that are closer to the mainland (or other large islands) will have higher rates of immigration. However, as more species inhabit the island, immigration will decrease (no more room). With more species come higher extinction rates.

They range from goods that are bought and sold to feelings of wonder and enjoyment. If damaged, they are difficult to return back to normal and could have economic as well as ecological ramifications.  services are necessary for other services to function. Photosynthesis allows plants to grow and therefore provide habitats and food. The biogeochemical cycles move the elements and molecules in order to support the existence of the ecosystem. The services are supporting, provisioning, regulating, and cultural

Genetic diversity is seen only on a population level. A diverse gene pool in a population will allow for greater survival of individuals. A population bottleneck is one way that genetic diversity may be lost. 
A variety of species in the ecosystem has the same effect. If one is wiped out, there may be another to take its place.
