Methods
Life forms: bats
Sites: 45
Sampling methods: no design,mist nets
Sample size: 1407 captures or sightings
Years: 1990 - 1992
Days: 90
Nets or traps: 15
Net or trap nights: 1350
Sampling comments: captures were in "65 islands of vegetation" of which "45 were rain forest"
15 12 m x 3 m mist nets per site set in a grid pattern and sampled for two nights (45 x 15 x 2 = 1350 net nights); there were 8760 net hours across all 65 islands but there is no breakdown
