In addition to species richness, a second component of diversity of a community is species evenness. evenness is the relative numbers of individuals in the sample. for example, consider the following two hypothetical samples from different tree communities. each sample has 100 individuals and four tree species species coast redwood california holly coast live oak california bay laurel community a community b 25 93 25 25 2 25 although the same number of species are found in the different communities- most ecologists agree that the first sample has a higher diversity than the second. why?

Answer and Explanation:

Despite the fact that it's now composed here that uniformity refers to the relative no. of entities in the sample, regarding species we can compose that species equality specifies the closeness in numbers  of every species in an environmental domain.  

Scientifically it tends to be clarified by assorted variety list, i.e., diversity index which measures the numerical equivalence in the the network.  

For instance a network with 10 animal groups where 99% of thes individual have a place with one animal categories is named as less differing than a network with 10 animal categories.  

In the given question, theoretically, If we move in both A and B group then we will experience increasingly various species in unit region of network A instead of in unit zone of network B.  

So we can say that first example has higher decent variety than the second.

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )
