The survey was conducted between the 23th November and 7th December 1998; this is the beginning of the dry season (Müller 1996). Temperature and relative humidity data were collected by using Hobo® Pro Series Temp + RH dataloggers at three different elevations (700 m, 1200 m, 1600 m). Dataloggers were positioned in the shade on tree trunks at two meters above the ground. Temperatures were recorded every minute for the duration of the study and ranged over 20-27°C at 700 m, 16-25°C at 1200 m and 16-23°C at 1600 m. Specimens were collected by hand captures, glue traps, drift fence/pitfall traps and quadrat sampling. Hand capture was executed by both scientific staff and local villagers. A total of 42 glue traps (Victor® mouse glue traps) were arranged in an approximately 1 km transect extending from the centre of a plantation into the depths of the forest. The traps were set in pairs at a height of 50 cm and 150 cm on trees of varying diameter. A total of four drift fence-pitfall trap lines were installed in four different habitats (Corn 1994). Drift fences were erected in a Y-shape with each arm of the Y extending 5 m. At the end of each arm and in the centre a 20 1 bucket was buried as a pitfall trap. Ten 8 x 8 m (64 m2) quadrat plots were sampled (Jaeger & Inger 1994). Areas were marked and a 1 m perimeter was cleared around the plot before sampling began. Vegetation (with the exception of trees > 10 cm diameter) and leaf litter were removed simultaneously from all four sides, starting at the perimeter and working Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - colorat
