Nest Abundance

In tropical forests, the leaf-litter stratum exhibits one of the greatest abundances of ant species. This diversity is associated with the variety of available locations for nest building. Ant nests can be found in various microhabitats, including tree trunks and fallen twigs in different stages of decomposition. In this study, we aimed to investigate undecomposed twigs as nest-building resources in the leaf litter of dense ombrophilous forest areas in the southeastern region of Brazil. Demographic data concerning the ant colonies, the physical characteristics of the nests, and the population and structural of the forest were observed. Collections were performed manually over four months in closed canopy locations that did not have trails or flooded areas. A total of 294 nests were collected, and 34 ant species were recorded.Pheidole,Camponotus, andHypoponerawere the richest genera observed; these genera were also among the most populous and exhibited the greatest abundance of nests. We found no association between population size and nest diameter. Only tree cover influenced the nest abundance and species richness. Our data indicate that undecomposed twigs may be part of the life cycle of many species and are important for maintaining ant diversity in the leaf litter.

Sample Points

The occurrence and duration of concrete frost were observed at 28 forested sites along an elevational gradient on a New Hampshire mountain. The presence of concrete frost was determined with an aluminum probe on 17 dates between November 1973 and June 1974. Concrete frost was found at all sample points in soils of coniferous forest ecosystems above 950-m elevation from mid-November to mid-May; some concrete frost remained into early June. Concrete frost occurred at most sample points in soils of transition zone forests that were composed of mixed hardwoods and conifers for 4 months, in soils of northern hardwoods forests for 2 months, and in soils of successional fir stands at low elevations for 4 months. Winter weather conditions and differences in leaf litter insulation probably accounted for the variation of soil frost beneath these forest types.

Primary Forests

The ant communities of the leaf litter were studied along an elevational gradient on Mount Kinabalu in primary rain forest systems ranging from dipterocarp hill forest to dwarf forest of the highest altitudes (560, 800, 1130, 1360, 1530, 1740, 1930, 2025, 2300, 2600 m a.s.l.). The litter ant fauna along the gradient included 283 species of 55 genera. The number of ant species in the leaf litter decreased exponentially without evidence of a peak in species richness at mid-elevations. This result is in contrast to many findings on altitudinal gradients in ants and other animal groups. Most ant species have a very limited altitudinal range leading to high turnover values when comparing communities of different altitudes. Of the ant species, 74% were even restricted to one site. As evident from this study, altitudinal ranges of species are very narrow. Elevational gradients are therefore extremely species-rich and might serve as a prime example of hot spots of biodiversity. This fact is of great concern when implementing conservation strategies.

The aim of this study was to compare in the same site the efficiency of the two most used techniques for sampling ant diversity, Winkler's extractors and pitfalls. We studied communities of leaf litter ants from the Brazilian Atlantic Forest, compared richness estimates for genera and species, and built species accumulation curves. These two methods resulted in a satisfactory sampling of richness; 21.3% of the genera and 47.6% of the species were collected exclusively with Winkler's extractors, whereas 6.4% of the genera and 9.5% of the species were collected exclusively with pitfalls. Winkler's extractor had proven to be the most efficient single sampling technique to estimate richness. However, pitfalls also recorded a significant portion of the total richness. Despite differences in efficiency, species accumulation curves for both techniques were similar, as well as the curve obtained with both methods combined. We noticed that Winkler's extractors were c. 74.0% more efficient than pitfalls in the Atlantic Forest. Therefore, sampling techniques must be used with a well-structured sampling design in order to advance knowledge on the ant fauna of Brazilian biomes, especially in the leaf litter, allowing more complete environmental analyses.

High Diversity

Secondary peatlands located in Kuala Dua Village, Kubu Raya Regency have various types of insects, one of which dominates is ants. Ants are members of the Order of Hymenoptera which have high diversity and complexity as social animals. Ants play a role in spreading seeds, other insect predators, spore spreaders, decomposers, ecological controllers. Information about the diversity of ants in Kubu Raya Regency is still very limited, especially those on peat land in Kuala Dua Village, Kubu Raya District, therefore research on ant diversity needs to be done with the aim to record the diversity of ants on these peatlands. Laying down the observation path is done intentionally (Purposive sampling). The method used is hand collecting and leaf litter sifting. The results shows that seven genera and four subfamily were obtained. Subfamily found is Formicinae, Ponerinae, Myrmicinae, and Dolichoderinae. The Subfamily Formicinae consists of the genus Camponotus, Colobobsis, Polyrhachis, Anoplolepis. The Ponerinae subfamily consists of the genus Leptogenys. Subfamily Myrmicinae consists of the genus Pheidole. The Dolichoderinae subfamily consists of the genus Ecphorella. The diversity index value on line 1 (1.30) is classified as medium category, line 2 (0.80) is classified as low category and line 3 (0.34) is classified as low category. The abundance index on line 1 (0.80) is classified as high category, line 2 (0.73) is classified as low category, line 3 (0.50) is classified as low category. The similarity index of ant species on line 1 and line 2 are (25%) which classified as low category. Line 1 and 3 are (57.14%) classified as medium category. The similarity index of ant species on line 2 and 3 (40%) were also classified as medium category.Keywords: ants, diversity, Kubu Raya District, peat land.
