WebRelative species abundance is calculated by dividing the number of species from one group by the total number of species from all groups. Community ecology [ edit] These measures are all a part of community ecology. Understanding patterns within a community is easy when the community has a relatively low number of species. WebThe average mass is the relative atomic mass, which can be easily calculated from the percentage composition ( % abundance). An element’s relative atomic mass, Ar, is calculated as follows: The mass numbers of its isotopes; The abundance of these isotopes; The formula that can be used to calculate the relative atomic mass:
