Basic information
Sample name: Garoua (1995)

Reference: N. Woin, J. A. Takow, and P. Kosga. 2005. Predatory ground-dwelling beetles (Carabidae and Staphylinidae) in upland rice fields in North Cameroon. International Journal of Tropical Insect Science 25(3):190-197 [ER 1179]
Country: Cameroon

Coordinate: 9° 17' N, 13° 22' E
Basis of coordinate: stated in text
Geography comments: "in the Benue valley"
Climate and habitat
Habitat: tropical/subtropical savanna
Altered habitat: cropland
Substrate: ground surface
MAP: 1000.0
Habitat comments: "a grassy savanna" that "is characterized by a Sudano-Sahelian climate" and specifically "a 2.3ha plot in 8 ha of neighbouring rice fields surrounded by other cereals, mainly maize and sorghum"
the "temperature range" is 13 to 42 C (apparently meaning record lows and highs)
MAP is a minimum estimate
Life forms: ground beetles, rove beetles
Sampling methods: line transect, pitfall traps
Sample size: 1024
Years: 1995
Nets or traps: 16
Sampling comments: "Eight pitfall traps were placed at a 12-m distance from each other, along each of the two field transects selected at 15 and 100 m from the bottom of the plot... The traps were emptied weekly" (number of sampling days is unclear, although it is possible that monitoring was continual for a year)
exactly the same data were published by Woin et al. (2006, Archives of Phytopathology and Plant Protection)
