Nest microhabitats and tree size mediate shifts in ant community structure across elevation in tropical rainforest canopies

Popis výsledku v původním jazyce

Declines or mid-elevation peaks in invertebrate diversity with elevation are often attributed to climate and geometric constraints. However, vegetation structure may also drive diversity patterns, via its effects on microhabitat use and competitive interactions. Here we investigate these effects on the diversity and community structure of tree-nesting ants over elevation. We exhaustively sampled ant nests in 1254 trees within continuous plots of primary rainforest at low (200 m a.s.l.), mid (900 m a.s.l.) and high (1800 m a.s.l.) elevation in Papua New Guinea. Ant diversity, nest abundance and tree occupancy peaked at mid-elevation. Tree size and nest microhabitat use were the strongest predictors of species richness and composition. Species co-occurrence patterns within trees differed with tree size, and with elevation. We conclude that the more extreme diurnal temperatures at higher elevations results in smaller colonies and a decrease in interspecific competition, boosting species co-existence at mid elevation.
