I was reading Hydroperiods of created and natural vernal pools in central Ohio: A comparison of depth and duration of inundation by Debra L. Gamble and William J. Mitsch (2008), and I came across this statement:
The dominant tree species in the vernal pool area were Acer saccharinum and Quercus palustris, while Ulmus americana, though smaller in diameter than the other trees listed, was the must abundant species...As at the New Albany, the most dominant tree species in the vernal pool area was Acer saccharinum, followed by Fraxinus pennsylvanica, while Fagus grandifolia was the most abundant species.
There seems to be a distinction between the terms dominance and abundance in the context of ecology. I've read some of the wikipedia articles on them, but I can't seem to find the difference in their meanings. They seem to both deal with the frequency that a species is in a population.
Any help is greatly appreciated.
