Sampling comments: "monthly samplings of 140 net-hours (10 nets open just after dawn for 7 hours, during two consecutive days)... we sampled trails alternately for a total of 30 net sites... we used data sets from Jul-Sep/2004, Apr-Sep/2005 and Jul-Sep/2006. OOur total sampling effort (net-h) was approximately 1,65 net-h" (i.e., 12 months x two days x 10 nets = 240 net days)
