Title: Structure and functioning of the decomposer
system in lowland rainforest
Team: Stefan Scheu, Mark Maraun (PIs), Rahayu Widyastuti
(IPB), Wilyus Wilyus (UNJA), Bernhard Klarner,
Valentyna Krashevska (Postdocs)
Aim:
Investigate the structure and functioning of the
belowground food web in tropical lowland rainforests
and its transformation systems focusing
on microorganisms and major microbial consumers,
i.e. micro- and mesofauna
Current status:
- Sampling of all transformation sites in Harapan
landscape and Bukit Duabelas is completed
- Litterbags for “Litter exchange experiment” and
“Ant exclusion experiment” from WP1 and WP2
prepared and will be installed in October-November
2013
- Sampling of forest sites and export of samples
pending
B09
Title: Aboveground patterns of biodiversity and
associated ecosystem processes across tropical
rainforest transformations
Team: Teja Tscharntke, Yann Clough (UGoe), Damayanti
Buchori, Akhmad Rizale (IPB), Fuad Nurdiansyah,
Kevin Darras, Lisa Denmead (PhD students)
Aims: - Taxonomic and functional diversity responses of
ants and birds to rainforest transformation
- Ant and bird exclusion experiment
- Ecosystem services and dis-services of oil palm
epiphytes
- Regional and landscape scale analyses
Current status:
- Bird diversity in core plots: sound recording of
birds is being analyzed (in time and space)
- Ant diversity in core plots: second round of ant
baiting and leaf litter samples is finished; species
identifications is in progress
- Plant, herbivore and ant samples for isotope
B10
analysis need to be transported
to Göttingen
- Young & productive oil palm plantations
in the Harapan landscape outside core
plots are selected and prototype exclusion is
ready
- Ant exclusion (all core plots) is planned from October
2013
Title: Landscape-level assessment of ecological
and socio-economic functions of rainforest
transformation systems
Team: Kerstin Wiegand, Katrin Meyer, Jann Lay (UGoe),
Claudia Dislich (Postdoc), Surya Tarigan (IPB),
Elisabeth Hettig, Fuad Nurdiansyah (PhD students)
Aim: - Integration of different ecological and socio-economic
functions on different spatial
scales to investigate trade-offs and synergies
between functions
Current status:
- What drives households’ land-use decision
making processes? A conceptual review of micro-level
studies in tropical regions (draft paper)
- Review of ecosystem functions in oil palm plantations
(work in progress)
