Altered habitat: fragment
Substrate: ground surface
MAT: 25.0
MAP: 1500.0
Habitat comments: "Originally the most common vegetation type in the area was tropical dry forest, or tropical semi-deciduous forest... The last remnants of the original tropical forest in the region are presently surrounded by different vegetation types, mainly by man-made pastures, but also by coastal scrub on sand dunes and secondary woody vegetation in different phases of succession"; the site is in "a fragment of tropical, semi-deciduous forest considered to be primary forest" (site area 32 ha)
Methods
Life forms: ants
Sampling methods: line transect, Winkler apparatus, baited, pitfall traps, other traps
Sample size: 5359 individuals
Years: 2011
Days: 6
Seasons: dry, wet or monsoon
Nets or traps: 75
Net or trap nights: 450
Trap spacing: 0.03
Basal area status: not applicable
Sampling comments: "Sampling was conducted during the rainy (August-September 2011) and dry seasons (March-April 2012)... three parallel transects 220 m long were used... transects were placed at least 100 m apart and more than 20 m away from any habitat edge. Along each transect, five sampling stations were placed, each with a 10 m radius and located 30 m apart from each other... Each sampling station was considered to be a complex sample, composed of a subterranean trap, two pitfall traps (one with tuna bait and another without bait), and two traps placed on trees at 2 m from the ground (one baited with tuna and the other with honey) [6]. They were recovered after 72 h of exposure in the field. Additionally, a 1 m2 sample of leaf-litter was collected from the ground at each sampling station and processed with Winkler sacks"
I am assuming there was one sampling event per season, i.e., six days of sampling per station
