In Indonesia, second largest rubber producer and largest oil palm producer worldwide, the vast majority of its rubber economy and almost half its oil palm acreage relies on smallholder farmers. This study compares canopy ant communities among four land-use systems in Jambi Province, Sumatra, Indonesia: 1) lowland rainforest, 2) jungle rubber (i.e., extensive rubber cultivation), and monoculture plantations of 3) rubber or 4) oil palm. Smallholder plantations of rubber and oil palm support less than 25% of the abundance and less than 50% of the canopy ant species richness in lowland rainforest, with intermediate levels in jungle rubber. Canopy ant communities from rainforest and jungle rubber were similar and differed from those in monoculture rubber and oil palm plantations, which each hosted distinct communities. Nestedness and turnover also differed between rainforest and jungle rubber on the one hand and rubber and oil palm on the other. This pattern was in part due to significantly greater proportions of tramp ants in the monoculture plantations: While virtually absent in forest (< 1%), six tramp ant species accounted for 9.8% of the collected ant individuals in jungle rubber, 26.6% in rubber and 41.1% in oil palm plantations (up to 88.1% in one studied plantation). Overall, this study improves our understanding of the effects of rainforest conversion to cash crop plantations of rubber and oil palm on ant communities by incorporating smallholder systems in one of the most important regions for oil palm and rubber production worldwide.

While epigaeic ants are extensively studied, hypogaeic, soil living ants are still neglected to a large extent. To remedy this, in this paper we explore the effects of rainforest transformation cash crop monocultures on abundance, richness and community composition of soil living ants (Formicidae). Ants in this study were procured as a by-product of extensive sampling of soil meso- and macrofauna along a land-use gradient from lowland rainforest via jungle rubber to monocultures of rubber and oil palm in Jami Province, Sumatra, Indonesia. Sampled in 32 plots of 50 * 50 m each, with three 16 cm * 16 cm * 5 cm soil cores each, we collected 2.079 worker ant individuals, belonging to 90 morphospecies from 37 genera and six subfamilies. Land use had a significant effect on abundance and richness, while distance-based community composition was not affected. Cumulatively, lowland rainforest had the highest number of ant species exclusively living in it, and the highest average ant abundance, although multiple comparison tests did not detect significant differences. We also found highest species richness in the lowland rainforest in one of the two investigated landscapes, while not significantly different from the agricultural systems in the other. High abundance variances among the sample sites suggest inadequacy of the sampling method, however. Despite that, our study provides a first glimpse into hypogaeic ant community responses to rainforest conversion to cash crop monocultures in Sumatra, Indonesia."],["dc.identifier.doi","10.1088/1755-1315/771/1/012031"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/88695"],["dc.language.iso","en"],["dc.notes.preprint","yes"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | B | B08: Struktur und Funktion des Zersetzersystems in Transformationssystemen von Tiefland-Regenwäldern"],["dc.relation","SFB 990 | Z | Z02: Central Scientific Support Unit"],["dc.relation.conference","2nd International Symposium on Transdisciplinarity Approach for Knowledge Co-Creation in Sustainability - Understanding Complexity and Transdisciplinarity for Environmental Sustainability"],["dc.relation.eventend","2020-11-04"],["dc.relation.eventlocation","Bogor, Indonesia"],["dc.relation.eventstart","2020-11-03"],["dc.relation.iserratumof","yes"],["dc.rights","CC BY 3.0"],["dc.subject.gro","Journal Article"],["dc.subject.gro","ABS"],["dc.subject.gro","sfb990_journalarticles"],["dc.subject.gro","sfb990_abs"],["dc.title","Effects of rainforest transformation to monoculture cash crops on soil living ants (Formicidae) in Jambi Province, Sumatra, Indonesia"],["dc.type","conference_paper"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Sampling method used for this research were scan sampling in the oil palm plantation area by capturing using insect nets. Butterflies are captured using insect nets then counted, marked (to avoid repeated calculations) and released again. Observation separated per one hour starting at 08.00 am to 04.59 pm. The results showed the highest diversity index of butterflies found was at 13.00-13.59 (H’=2.39) with total species number was 34 species. Overall, the butterfly diversity index found was relatively low (H’=1.78) with total species number was 54 species.
