Heterogeneity

Definition

Heterogeneity is the quality or state of being diverse in character or content. In biology, it often refers to the variety within a population, ecosystem, or genetic pool.

5 Must Know Facts For Your Next Test

1. Heterogeneity increases resilience in ecosystems by providing a wider range of responses to environmental changes.
2. High genetic heterogeneity within a species can enhance its ability to adapt to changing conditions and survive threats.
3. Habitat heterogeneity supports greater biodiversity by offering diverse niches for different species.
4. Conservation efforts often focus on maintaining or enhancing heterogeneity to preserve ecosystem functions and services.
5. Loss of heterogeneity due to habitat destruction, climate change, or human activities can lead to reduced biodiversity and increased vulnerability.
