[sci.bio] Looking for Species Counts

ls2o+@andrew.cmu.edu (Lael Schooler) (10/15/90)

I am looking for a record of the animals encountered in an
environment--how appearances of animals of various types repeats over
time. 

Are there biologists that study this? If so, what do they call themselves?

Thanks in Advance
