Geography
Country: Mexico

State: Chiapas


Coordinate: 16° 51' 23" N, 93° 12' 6" W
Coordinate basis: stated in text

Geography comments: coordinate is the average of ranges given in text
elevation range 767 to 1088 m

Environment
Habitat: tropical/subtropical dry broadleaf forest

Altered habitat: pasture

Substrate: ground surface

MAP: 1200.0

Habitat comments: "tropical dry forest, fragments of secondary forest and fallow land in various stages of succession" and specifically "pasture adjacent to a cattle stable"
MAP stated in text; CMT and WMT unclear because the nearest climate station (76741, Coatzacoalcos) is at sea level

Methods
Life forms: scarab beetles

Sites: 1

Site length: 250

Sampling methods: line transect,baited,pitfall traps

Sample size: 200 individuals

Years: 2004, 2005

Days: 20

Seasons: wet or monsoon

Nets or traps: 6

Net or trap nights: 120

Sampling comments: one transect with six human excrement-, cow dung-, or squid-baited pitfall traps separated by 25 m (i.e., a total transect length of 125 m) that were sampled on 20 occasions "during two rainy seasons: from May to October 2004, and from May to August 2005"
there is a conflict in the text, with "bait replaced every 48 h" but traps supposedly "visited" for 6 h on each occasion; I assume that 20 visits means 20 sampling days, period
