| 11. | Species richness, therefore, is a sign of environmental wealth and health.
|
| 12. | The technique does not recognize species abundance, only species richness.
|
| 13. | Plant species richness of snag forests can be much higher than in unburned forests.
|
| 14. | They increase species richness and animal abundance by providing shelter and improved water quality.
|
| 15. | It also demonstrated that PD led to greater preservation of'feature diversity'than species richness alone.
|
| 16. | Today, overexploitation and misuse of natural resources is an ever-present threat for species richness.
|
| 17. | At these points, species richness is neither increasing nor decreasing.
|
| 18. | The presence of too much nitrogen can cause declines in species richness and abundance.
|
| 19. | Plant species richness directly reflects spatial heterogeneity in an ecosystem.
|
| 20. | Additionally, producers can increase plant and species richness through grazing, by providing an adequate habitat.
