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. WebExample #15: The relative atomic mass of neon is 20.18 It consists of three isotopes with the masses of 20, 21and 22. It consists of 90.5% of Ne-20. Determine the percent abundances of the other two isotopes. Solution: 1) Let y% be the relative abundance of Ne-21. 2) Then, the relative abundance of Ne-22 is: (100 − 90.5 − y)% = (9.5 − y)% green hawthorn crataegus viridis
