WebApr 8, 2024 · Species richness and species evenness constitute species biodiversity. It increases with an increase in explored areas. When species explore other areas than initially found one, they expand their habitat and thus, biodiversity increases. However, other factors govern it such as climatic factors and availability of food to sustain organisms.

WebMay 9, 2013 · In the paper by Allouche et al. ( 1 ), the authors suggested that species richness decreases at high levels of habitat diversity because the area available per habitat decreases [area–heterogeneity tradeoff hypothesis (AHTO)].

WebAt that point, species richness is at equilibrium. In this figure, equilibrium species richness is a little less than 400 species. 2. It is stable, as you can see from examination of Figure 2. When species richness is less than the equilibrium value, the immigration rate is higher than the extinction rate, and so species richness will increase.
