Abstract

Abstract. Triyogo A, Budiadi, Widyastuti SM, Subrata SA, Budi SS. 2020. Abundance of ants (Hymenoptera: Formicidae) and the functional groups in two different habitats. Biodiversitas 21: 2079-2087. Land development often affects the quantity and diversity of ants (Hymenoptera: Formicidae). The aim of this study, therefore, was to determine and compare the ant species abundance and the functional groups between two different habitats, representing land development, including pioneer and agroforestry. This research involved a survey of the ants at the Forest Research Education (FRE) of Wanagama I Yogyakarta, and data were accumulated over a period of five months (April, May, June, July, and August). In addition, pit-fall trap and direct collection methods were used, involving the placement of 54 pit-fall traps at two habitats, and the ant specimens were retrieved after a two day period. The results show the total individual abundance of 2,310 and 2,067, on agroforestry and pioneer, respectively. Furthermore, the species richness and diversity index was higher in agroforestry (7; 2.01), compared with pioneer (6; 1.49), where the three dominant species include, Anoplolepis gracilipes, Solenopsis sp., Odontoponera denticulata; and Anoplolepis gracilipes, Odontoponera denticulata, Camponotus sp., respectively. Conversely, the highest amount of invasive ants (Solenopsis sp.) was observed in agroforestry, which negatively impacted on the presence of native species (Odontoponera denticulata). In addition, PCA analysis showed the development of three ant groups on each habitat, hence agroforestry made more real differences in the aspect of species abundance, and none in terms of richness. Therefore, notable differences were observed in the ant communities between both habitats, and agroforestry was indicated as a disturbed area, based on the increment in tramp and invasive ants, alongside low abundance of native and functional groups.

Composition & Ecological Role of Soil Macrofauna in Selorejo and Punten Citrus Farming, Malang - East Java

“…Formicidae families are the most common group of insects found on agricultural and croplands. Ecosystem habitat in this research presented the former condition of that land as increasing quality, which was dominated by a predator as the Formicidae, and also the ones who can survive in degraded land [25]. However, citrus farming is covered by dominant species of grass or above-ground vegetation as a food resource and as a protectant against predators.…”

Diversity and species composition of ants at coffee agroforestry systems in East Java, Indonesia: Effect of habitat condition and landscape composition

“…The results are similar with the analysis by Marja et al (2022) that landscape composition can enhance species richness and abundance of arthropods in agricultural landscapes, agroforestry was the most dominant class in almost all landscapes. Triyogo et al (2020) showed that disturbed habitats (agroforestry) have greater ant diversity. Primary and secondary forests can hold high numbers of ant species (Solar et al 2016) and increased forest area can increase ant diversity (Kuate et al 2015).…”

The Composition, Abundance, and Biodiversity of the Insect Family of the Hymenoptera Order on Swampy Wetlands (SW) and Land Conversion (LC) in Palembang City

“…The Formicidae family are ants that are very adaptable to new environments, including environments where human activities are present. Informed by Triyogo et al (2020) the abundance of individual ants of the Formicidae family is higher in industrial forests where human activities are present compared to natural forests. Peck, Mcquaid, and Campbell (1998) stated that Anoplolepis gracilipes are an ant species that is easy to adapt, has a very wide distribution, and can reduce the diversity of other ant species.…”
