How does species evenness affect biodiversity
WebAs natural communities change in biodiversity (species richness or evenness), it matters which species are added or lost. This is because species tend to vary strongly in their functional roles. Moreover, species tend to have vastly different probabilities of … WebEffect of Soil Moisture on Total Species Abundance There was no significant effect of soil moisture (X 2 =0.11 p=0.74), stream distance (X 2 =1.71m p=0.19), or the interaction between the two (X 2 =1.54, p=0.22) on the total species abundance overall or at each individual distance. Thus, the total number of species present is correlated
