Figure 1. Combined number of frogs captured on nine study sites (with cattle troughs) at Pocosin Lakes National Wildlife Refuge, NC in 1994. July 4-6 session numbers adjusted for incomplete trapping data (weather prevented) from July 6. Note two-day trapping sessions from Aug 17 (because no new individuals were caught beyond day 1 of each session from Aug. 17-Sept. 25, we made no adjustments to numbers).
