Contribution of wet zone coconut plantations and non-agricultural lands to the conservation of ant communities (Hymenoptera: Formicidae) in Sri Lanka

Agricultural practices are blamed for the reduction of ant diversity on earth. Contribution of four coconut plantations (CP) and four non-agricultural lands (NL) for sustaining diversity and relative abundance of ground-dwelling and ground-foraging ants was investigated by surveying them from May to...
