What is the biological Species concept?
The concept defines a species as a group of natural populations whose members can interbreed and produce healthy, fertile offspring. However they can't do so with members of other groups.

What is Rapoport's Rule?
The the latitude decreases the geographic range for a species shrinks.

What is an Ecological Footprint?
- How much land is needed to support your lifestyle
-The impact of a person or community on the ecosystem, defined as how much land is needed to sustain their use of the resources.

What is a Metapopulation?
It is a group of separate, smaller populations of the same species that live in different areas and interact with each other.

Three Goals of Conservation Biology?
1. Document Biological Diversity
2. Examine Human Impacts on living Systems
3. Prevent extinction of species, maintain Biological diversity and restore communities

At what latitude are species highly diverse and condense?
Equator

Define Intrinsic Value?
Moral:Value based on individual sense of right and wrong
Ethics: Value based on social norms and codes of conduct

What is a closed population, and where can you find it?
A closed population is defined as a population only determined by birth rate and death rate. You can find it in zoos, small islands, laboratory.

What is the Difference between Alpha, Beta, and Gamma Diversity?
Alpha Diversity: Diversity measured in a certain area.
Beta Diversity: Diversity change across multiple areas.
Gamma Diversity: beta/alpha
