How does latitude affect species richness
WebThe decrease in diversity when moving from lower latitudes towards higher latitudes is referred to as Latitudinal Diversity Gradient. Generally it is observed that the diversity richness is more in the areas near the equator than at the poles. …. Altitude also affects the diversity richness inversely. Webproductivity appears to have an effect on richness beyond that expected on the basis of the number of individuals (Hurlbert & Jetz, 2010). Recently, a model that integrated area and productivity over geological time together with temperature succeeded in explaining 77% of current-day species richness of the four major terrestrial vertebrate
