Abstract

Ants are the most abundant animals in tropical habitats and have been widely studied in natural and semi-natural tropical systems. However, species in urban tropical habitats remain poorly studied, despite their abundance and potentially important roles in urban ecosystems and pest dynamics. We investigated the ant fauna of Bogor and its surroundings to contribute to the characterization of the myrmecofauna of one of Southeast Asia’s most densely populated regions. Ants were collected both by hand collection and from honey baits in the most common habitats: garbage dumps, households, and home gardens. In total, 94 species were recorded, over two thirds of which occurred in home gardens, which underlines the importance of vegetated habitats for urban planning to support complex ant assemblages. Twelve sampled species are well-known as tramp species that occur primarily in human-dominated landscapes. The two tramp species Anoplolepis gracilipes and Paratrechina longicornis dominated ant assemblages in all locations and most habitat types. The assemblages of tramp species were affected by habitat type, whereas that of non tramp species were not. Forty-five species were also recorded in the Bogor Botanical Garden and five species are also known to be common in cacao agroforests. Hence, research in urban tropical habitats can increase our knowledge of the occurrence of ant species, allowing us to better assess the biodiversity and conservation potential of semi-natural habitats.

Abstract

The ant species diversity in tropical Asia has been investigated in several locations, however, these studies mainly focused on well preserved forests or plantations. The ant fauna in urban parks has only been investigated in a limited number of locations in Singapore, Hong Kong, Macao, and Indonesia. We investigated the ant fauna in the Purwodadi Botanical Gardens, East Java, and compared it to the ant fauna obtained in the Bogor Botanical Gardens. In the Purwodadi Botanical Gardens, we employed the following sampling methods that were also carried out in Bogor: (1) visual searching of ants on tree trunks, (2) visual searching of litter and top-soil ants by hand sifting (3) visual searching of ant colonies, (4) visual searching of foraging workers. In total, 109 species in 44 genera from 9 subfamilies were collected. The number of species collected from litter and soil in Purwodadi was remarkably smaller than that in Bogor, while the ant species diversity on tree trunks was similar to that of Bogor. Of the109 species, 68 were common to Bogor. Arboreal ants were more similar than ground ants between Bogor and Purwodadi.
