Download Solution PDFThe correct answer is beta diversity
Concept:
- Beta diversity refers to the change in species number and composition, or turnover of species, as one moves from one community to another. It is a measure of the difference in species composition between ecosystems or habitats.
- Beta diversity is important in understanding the extent of biodiversity and the ecological differences between habitats. It helps in identifying areas with unique species compositions and can guide conservation efforts.
Explanation:
- Alpha diversity: This refers to the diversity within a particular area or ecosystem and is usually measured by the number of species (species richness) in that ecosystem. It does not account for differences between ecosystems.
- Beta diversity: This measures the change in species diversity between ecosystems or habitats. It indicates the turnover of species from one habitat to another and helps in understanding the spatial differentiation of biodiversity.
- Gamma diversity: This refers to the total diversity of species within a region or landscape and is a combination of both alpha and beta diversity. It provides an overall picture of biodiversity across larger geographic scales.
- Adaptive evolution: This is a process by which organisms become better suited to their environment through changes in their genetic makeup over time. It is not directly related to measuring species diversity.
