Study Notes
Understanding Biological Communities
- A biological community refers to a group of different species that coexist and interact with each other in a specific environment.
Key Properties of a Community
- Collective properties: characteristics that can be observed when individual organisms are grouped together, such as population density and species richness.
- Emergent properties: unique characteristics that arise from the interactions among individual organisms, such as resource competition and predator-prey relationships.
Species Diversity in a Community
- Species diversity represents the variety of different species present in a community, including the number of species, their relative abundance, and their distribution.
First Steps in Community Analysis
- The first job when given a designated community is to identify and inventory the species present, including their abundance and distribution.
Individuals in Nature
- Individuals are rarely found alone in nature, as they often exist as part of a larger community, interacting with other organisms and their environment.
