Batcapture:
Understanding seasonality and species composition of bat population
Description
Scientists studied Bat community on Barro Colorado island in Panama in late 70's. Bats were captured on many nights regularly throughout the year to understand species composition of the bat community and its dynamics through the year.
Following questions are of interest:
a) For a given species, do capture proportions change with season? If yes, how?
b) Are capture proportions over months similar across species? If not, what are the salient differences?
c) Consider the variable, average number caught per night in a month. Does it depend on number of nights/month/ species?
