Ant Community Structure

AbstractIn mixed tropical landscapes, savanna and rain-forest vegetation often support contrasting biotas, and this is the case for ant communities in tropical Australia. Such a contrast is especially pronounced in monsoonal north-western Australia, where boundaries between rain forest and savanna are often extremely abrupt. However, in the humid tropics of north-eastern Queensland there is often an extended gradient between rain forest and savanna through eucalypt-dominated tall open forest. It is not known if ant community structure varies continuously along this gradient, or, if there is a major disjunction, where it occurs. We address this issue by sampling ants at ten sites distributed along a 6-km environmental gradient from rain forest to savanna, encompassing the crest and slopes of Mt. Lewis in North Queensland. Sampling was conducted using ground and baited arboreal pitfall traps, and yielded a total of 95 ant species. Mean trap species richness was identical in rain forest and rain-forest regrowth, somewhat higher in tall open forest, and twice as high again in savanna woodland. The great majority (78%) of the 58 species from savanna woodland were recorded only in this habitat type. MDS ordination of sites based on ant species composition showed a continuum from rain forest through rain-forest regrowth to tall open forest, and then a discontinuity between these habitat types and savanna woodland. These findings indicate that the contrast between rain forest and savanna ant communities in tropical Australia is an extreme manifestation of a broader forest-savanna disjunction.

Ant Community Structure

AbstractUnderstanding ant community structure is of great interest among ant ecologists, since these insects stand out for their diversity, especially in the tropics, where they show high co-occurrence levels in many habitats. Discovery-dominance tradeoff is considered an important mechanism acting on ant community structure in many habitats, ensuring species co-occurrence by a temporal share of resources. We investigate the occurrence of this structuring mechanism in a Pheidole (Hymenoptera: Formicidae) assemblage at Atlantic Rainforest remains in south Brazil. If the discovery-dominance tradeoff is structuring this ant community, we expect that some species should be better to found food sources quickly, whereas other species arrive later and dominate food sources for their own consumption. We established 55 sampling locations at two sites, settling one sardine bait in each sampling unit to take note on the resource use by ants in a three-hour experiment. There was no distinction among species in terms of their ability to found or dominate food sources, which suggests that the discovery-dominance tradeoff is not structuring this assemblage. The low levels of aggression between ant species could avoid the establishment of dominance hierarchies, whereas territoriality could be acting to ensure resource partitioning. Also important is the fact that tradeoffs can vary with spatial scale, which can be assessed in further studies.
