|
Genetic Diversity |
-the variability in the genetic makeup among individuals within a single species. - differences in genes in organisms with in a population |
|
|
Species |
-the variety of species on the planet earth and in different habitats on earth. |
|
|
Ecological |

5 Major threats to biodiversity (HIPPO) |
1. Habitat destruction 2. invasive species 3. pollution 4. (over) population 5. Over harvesting |
|
|
Population |
a group of interbreeding individuals that occupy the same area at the same time |
|
|
How do you describe a population (4) |
1. Pattern of spacing 2. Distribution of age classes 3. Size of population 4. life history traits |
|
|
Spacing within a population |
provides insight into the environmental associations and social interactions of individuals in a population |
|
|
Types of spacing |
1.Clumped: common in organisms that are social or need the same resources 2. Uniform: territorial animals 3. Random: random |
|
|
Exponential Growth Rate |
populations with out limiting factors |
