A group of people with a common characteristic or interest living together within a larger society
One of a small number of species which dominate in an ecological community
A keystone species is a species that plays a critical role in maintaining the structure of an ecological community and whose impact on the community is greater than would be expected based on its relative abundance or total biomass.
Captive breeding is the process of breeding animals in human controlled environments with restricted settings, such as wildlife reserves, zoos and other conservation facilities.
An ecosystem engineer is any organism that creates or modifies habitats.
Ecological succession is the phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following disturbance or initial colonization of new habitat
Habitat loss is linked to the ever-increasing demands for land by the exploding human population and the commercial demands for natural resources.

Extinction is the conditioning phenomenon in which a behavior that has been previously reinforced no longer results in the reinforcing consequences and, therefore, the behavior stops occurring in the future
Biodiversity Crisis is the number and variety of organisms found within a specified geographic region.The variability among living organisms on the earth, including the variability within and between species and within and between ecosystems
Restoration ecology is the scientific study and practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human intervention and action, within a short time frame.
Reforestation is the natural or intentional restocking of existing forests and woodlands that have been depleted, usually through deforestation.[
Biological control is a method of controlling pests using other living organisms
Bioremediation is the use of micro-organism metabolism to remove pollutants.
Bioaugmentation is the introduction of a group of natural microbial strains or a genetically engineered variant to treat contaminated soil or water.
