31. This diagram shows the effect of an island s size on the amount of species richness . 32. Many localities have a rather low species richness . 33. For insectivores, abundance and species richness of most frequently captured birds declined significantly in post-isolation reserves. 34. These organisms can have a large impact on the species richness and landscape-level heterogeneity of an area. 35. Many organism groups have most species in the tropics, which leads to latitudinal gradients in species richness . 36. The presence of some ecosystem engineers has been linked to higher species richness at the landscape level. 37. Just as importantly, it increases species richness . 38. In the warmer northern climate, kauri forests have a higher species richness than those found further south. 39. This process not only helps grizzlies access their food, but also increases species richness in alpine ecosystems. 40. But perhaps you meant species richness .
