Question: Does Bat Species Diversity Differ From February to March?

• Study Design

– Capture bats over four nights in February (February 7 – 10) and over four nights in March (March 9 – 13)

– 12 traps per night

– Sample soon after dusk and again in the morning

– Determine species, sex, age, measure forearm length, mass

How Can We Visualize These Data?Species Abundance Curves

• X axis- order the species from most abundant to least abundant

• Y axis- the abundance of each species
