Altered habitat: plantation
Substrate: ground surface
WMT: 29.9
CMT: 26.2
MAP: 2825.0
Habitat comments: "Mean annual rainfall in the region ranges from 6000 mm in the western side to 1700 mm in the eastern side of the river basin and temperature varies from a maximum of 35 C in April to a minimum of 16 C in December... Nearly 60% of the river basin is covered by vegetation, of which 15% is deciduous forest habitat... Plantations were primarily monocultures of Acacia, Casuarina... Scrub jungle was characterised by thorny bushes and shrubs that were less than a metre in height" (evergreen habitats are not detailed)
climate data based on station 43192 (Panjim)
Life forms: ants
Sites: 10
Site area: 2.700
Sampling methods: quadrat, sieves, baited, pitfall traps, hand capture
Sample size: 1153
Sampling comments: each of 10 sites consists of three 30 x 30 m quadrats placed on an 800 m transect that were each sampled once
"At each 30 m 30 m plot, a suite of sampling methods were used to collect ants: bait traps, pitfall traps, Berlese leaf litter sampling and hand collection... Sampling was carried out once at each plot. Baits were provided as both terrestrial and arboreal and consisted either of honey, tuna or fried coconut. Terrestrial baits were placed on the ground and arboreal baits were tied to a tree 2 m above the ground... Five pitfall traps were laid at every plot for a 24-h period" (total sampling effort not calculable)
