How does latitude affect species richness
WebHow does latitude affect species richness? As we move from the equator to the north and south poles, the number of species declines. Define the time/stability hypothesis. States that diversity is directly related to the length of time that a region has existed. WebSep 4, 2024 · Species Richness ( s) is a relative term that refers to the number of species in a community, and is directly associated with measuring the diversity of species in a given area. A related term, evenness (E), is another dimension of diversity that defines the number of individuals from each species in the same area.
