MAP: 1100.0
Habitat comments: "the weather in the area of study is classified as Cw2, which means sub-humid temperate (18 to 20°C) with showers in summer (200 to 1 800 mm) and temperate forest" (not clear if the rainfall figures are annual)
tree stratum consists of "species of Quercus... Arbutus xalapensis Kunth, Alnus sp., and Pinus sp."
climate data are for the Valley of Toluca and are from Flores et al. (2015, Revista Mexicana de Ciencias Agrícolas)

Methods
Life forms: ants
Sampling methods: quadrat,baited,pitfall traps
Sample size: 171 individuals
Years: 2009, 2010
Days: 3
Seasons: dry,wet or monsoon
Nets or traps: 48
Net or trap nights: 192
Sampling comments: "a study area of 2 500 m2 was selected in each zone, and 16 pit fall traps were placed with 10 m of separation between them... The collections were carried out from February to March 2009 (dry season) and one more August through September 2010 (rainy season), which produced a total of 192 traps" across this sample and the two others; "containers were covered with a plastic dish that held a vial with a lure made from a mixture of oats and honey" and were "opened for 72 h"
