The spatial distributions of many tropical arboreal ant species are often arranged in a mosaic such that dominant species have mutually exclusive distributions among trees. These dominant species can also mediate the structure of the rest of the arboreal ant community. Little attention has been paid to how diet might shape the effects of dominant species on one another and the rest of the ant community. Here, we take advantage of new information on the diets of many tropical arboreal ant species to examine the intra- and inter-guild effects of dominant species on the spatial distribution of one another and the rest of the tropical arboreal ant community in a cocoa farm in Bahia, Brazil. Using null model analyses, we found that all ant species, regardless of dominance status or guild membership, co-occur much less than expected by chance.

Impact of tree isolation on aboreal and ground ant communities in cleared pasture in the Atlantic rain forest region of Bahia, BrazilMajer, Jonathan; Delabie, J. (1999)The Atlantic rain forest of south-eastern Brazil has been substantially cleared, resulting in the creation of a fragmented landscape. In addition to the small fragments of forest that remain, the pasture is often scattered ...
Ant assemblages in isolated trees are more sensitive to species loss and replacement than their woodland counterpartsGove, Aaron; Majer, Jonathan; Rico-gray, V. (2009)Isolated trees possess an arthropod assemblage different to that found in woodland trees. While isolated trees become an increasingly dominant part of many landscapes, with ‘off reserve’ habitat conservation potential, ...
