Smaller population sizes on islands accelerate some ecological processes, which may decrease the time needed for perturbations to affect community composition. We surveyed ants on 18 small tropical islands to determine the effects of island size, isolation from the mainland, and habitat disturbance on ant community composition. Location Thousand Islands Archipelago (Indonesian name: Kepulauan Seribu) off Jakarta, West Java, Indonesia. Methods Ants were sampled from the soil surface, leaf litter and vegetation in all habitat types on each island. Island size, isolation from the mainland, and land-use patterns were quantified using GIS software. The presence of settlements and of boat docks were used as indicators of anthropogenic disturbance. The richness of ant communities and non-tramp ant species on each island were analysed in relation to the islands' physical characteristics and indicators of human disturbance. Results Forty-eight ant species from 5 subfamilies and 28 genera were recorded from the archipelago, and approximately 20% of the ant species were well-known human-commensal 'tramp' species. Islands with boat docks or human settlements had significantly more tramp species than did islands lacking these indicators of anthropogenic disturbance, and the diversity of non-tramp species decreased with habitat disturbance. Main conclusions Human disturbance on islands in the Thousand Islands Archipelago promotes the introduction and/or establishment of tramp species. Tramp species affect the composition of insular ant communities, and expected biogeographical patterns of ant richness are masked. The island with the greatest estimated species richness and the greatest number of unique ant species, Rambut Island, is a forested bird sanctuary, highlighting the importance of protected areas in preserving the diversity of species-rich invertebrate faunas."],["dc.identifier.doi","10.1111/j.1365-2699.2009.02194.x"],["dc.identifier.isi","000273771100003"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/20660"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley"],["dc.relation.issn","1365-2699"],["dc.relation.issn","0305-0270"],["dc.title","Ant communities on small tropical islands: effects of island size and isolation are obscured by habitat disturbance and 'tramp' ant species"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Changes in species composition and disrupted trophic interactions between pests and their natural enemies may also result causing decreased ecosystem services. We studied the effects of forest habitat transformation on the community structure of ants, which include major biological control agents. We focused on four types of land use around Harapan Forest (Harapan) and Bukit Duabelas National Park (BDNP), Jambi, Sumatra, Indonesia: forest, jungle rubber, rubber plantations and oil palm plantations. Four replicate patches of each land-use type were sampled, with plot sizes of 50 x 50 m at each of the 32 sites. Ants were collected by hand in combination with tuna and sugar baiting on three strata i.e. leaf litter, soil and tree. We found 104 ant species in total. Surprisingly, ant species richness per plot was not significantly different among land-use types, both in Harapan and BDNP. However, few ant species were shared among different land-use types. Forest and jungle rubber communities are relatively similar to each other (but still different), and distinct from communities in oil palm and rubber plantations. We conclude that conversion of remnant forested habitats to plantations would result in a net loss of ant species, even though ant species richness in plantations and forested habitats are similar."],["dc.identifier.doi","10.20362/am.007008"],["dc.identifier.isi","000367360700008"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/38258"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | B | B09: Oberirdische Biodiversitätsmuster und Prozesse in Regenwaldtransformations-Landschaften"],["dc.relation.issn","1985-1944"],["dc.subject.gro","sfb990_journalarticles"],["dc.subject.gro","sfb990_abs"],["dc.title","Agricultural land use alters species composition but not species richness of ant communities"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

However,the incidence of BPD was higher in ant species rich trees, presumably because moreant species were pathogen vectors.

Although many studies investigate management impacts, data on the long-term change of species communities in agroecosystems are scarce. We analysed the long-term change in diversity and composition of ant communities in cacao agroforestry systems in Central Sulawesi, Indonesia and attempted to disentangle the driving factors of this change. Ant communities were resampled in 2009 from sites for which previous surveys had been conducted either in 2001 (the rainforest-poor Palolo region) or 2003 (the rainforest-rich Kulawi region) using insecticide fogging. Ant community composition changed significantly over time in Palolo and Kulawi. The change in ant species richness differed between regions. Species richness increased in Kulawi, probably due to the increasing availability of nest sites and microhabitats as trees grow larger and older. In the Palolo region, species richness decreased, suggesting that the high local intensification and landscape-wide changes may have counteracted the effects of tree age. Changes in ant communities over time were significant, but were more difficult to explain than expected, despite clear difference in management changes within and between regions. The findings suggest that the landscape-scale differences between the two study regions play a more important role for species diversity and its composition than changes in local management. This highlights the importance of long-term studies across contrasting landscapes for better understanding the consequences land-use intensification has on tropical biodiversity."],["dc.identifier.doi","10.1111/j.1752-4598.2012.00219.x"],["dc.identifier.gro","3149875"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6582"],["dc.language.iso","en"],["dc.notes.status","public"],["dc.relation.issn","1752-458X"],["dc.title","Long-term change of ant community structure in cacao agroforestry landscapes in Indonesia"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
