Study Notes
Species Diversity
- Refers to both the variety of different species and the abundance of individuals within a community.
- Important for ecological balance and ecosystem functionality.
Genetic Diversity
- Represents the range of genetic characteristics within a species.
- Higher genetic diversity allows species to adapt better to environmental changes and resist diseases.
Ecosystem Diversity
- Encompasses the variety of habitats found in a specific geographical area.
- Crucial for sustaining different life forms and maintaining ecological processes.
Components of Species Diversity
- Consists of two key elements: number of different species in an area and their relative abundance.
- A balanced community features a rich variety of species alongside a good distribution of individuals.
Species Diversity Index
- Calculated using the formula: N(N-1)/Σn(n-1), where N is the total number of organisms, and n is the number of organisms of each species.
- A useful tool for quantifying species diversity in a given habitat.
Impact of Agriculture on Species Diversity
- Agriculture practices, particularly selective breeding, can lead to a decrease in genetic diversity.
- Farmers often promote a few desirable species, leading to competition for resources among less favored species, resulting in reduced biodiversity.
Impact of Deforestation on Species Diversity
- Deforestation directly harms plant species, leading to diminished species diversity.
- The destruction of habitats significantly affects animal populations, often leading to declines or extinctions.
