*Pollution *Deforestation *Climate Change *Urbanization *Introduced Species *Disease *Poaching *The list goes on and on… *IN: What sorts of events might threaten biodiversity?

• Ecosystem stability: the ability of an ecosystem to maintain its structure and function despite disturbances. • Ecosystem structure includes physical and geological structures of the landscape, biodiversity, population sizes and interactions • Ecosystem function refers to processes such as water and nutrient cycling and biomass productivity *

Resistance *An ecosystem’s ability to keep its structure & continue normal functions, even after a change * Resilience *An ecosystem’s ability to regain normal structure and function after a change

*Species respond to environmental change in ways that enable them to maintain homeostasis. * *Populations respond in ways that reflect the success or failure of members of the population to survive and reproduce. *Communities respond to environmental change in ways that reflect the responses of the species and populations in the community.
