SFB 552: C2 - Diversity and spatial distribution of herbaceous and woody plant assemblages in relation to natural and anthropogenic factors (Project)
With the general aim of documenting and interpreting the spatial variability of plant diversity and composition in relation to environmental factors (elevation, soil, topography, climate) and land use in the study region, we will (a) gather tree data across the elevational gradient from 200 m to 2500 m as a basis for forest biodiversity and structure modelling in the scope of focus 1, (b)...

Data collection on the use of of plant protection agents in the forest; Participation in the collection and evaluation of anthropogenous immissions regarding forest damage (Project)
Report on the use of plant protection agents in forests.

SFB 552: C3 - Insect diversity and trophic interactions in relation to agroforestry management and ENSO droughts (Project)
Agricultural intensification and ENSO droughts are major drivers of global change. Here, we focus on little known effects of local agroforestry management (weeding, fertilization), the surrounding landscape (distance to nearest forest) and reduced rainfall (in agroforestry vs. forests) on insect diversity and ecosystem services such as pollination, biological control (herbivory and predation) as...

SFB 552: C4 - Drought effects on vitality and activity of tree fine roots in natural forest and agroforestry systems (Project)
n the context of the roof experiments of Focus 3, this subproject investigates the effects of moderate and severe droughts on biomass, vitality (as indicated by non-structural carbohydrate content) and activity of fine root roots of selected tree species in the natural forest and the cacao agroforest systems. With 15N-tracer experiments and root miniature sap flow gauges we test the hypotheses...

SFB 552: C6 - Diversity of endophytic fungi on cacao and impact on plant pathogenherbivorous insect interactions in relation to agroforestry diversity and management (Project)
This subproject aims at assessing the diversity of endophytic fungi in cacao trees in relation to agronomic practices. Our central hypotheses are that (i) the diversity of endophytic fungi is declining from agroforestry to monoculture plantations, that (ii) the incidence of herbivorous pests, ants, and plant pathogens is related to the diversity of fungal endophytes, that (iii) trees harbouring a...

SFB 552: C7 - Stability of rainforest margins in space and time: Holocene rainforest, climate, fire, human impact and land use dynamics in Sulawesi, Indonesia (Project)
For understanding the stability of rainforest margins and for future sustainable land use management an integrated study including changes on past vegetation, biodiversity, climate, fire, human impact and land use dynamics is needed. Special attention will be given to Holocene human impacts on vegetation, land use changes, history of rattan use, adaptation to environmental changes, and ENSO...

SFB 552: D5 - Central data management: Multivariate spatial analysis and modelling of the dynamics of rainforest margins (Project)
After the implementation of the technical as well as administrative infrastructure in phase 2 we will continue to maintain and extend the web-based spatial information system and the compilation and provision of the SFB data along with their meta data in accordance with the Protocol for Data Exchange. The focus for phase 3 will be on the integration of the many disciplines by means of...

Assessment of wheat cropping systems from an economical, ecological and the society's perspective - the case of plant disease resistance breeding (Project)
Cultivars are generally characterized either by high yield and a need of intensive fungicide treatments or by lower yields and qualities with a reduced need of fungicide treatments. An increase in yield therefore often is accompanied by less sustainable cropping systems. The decision of growers on the choice of the most appropriate cultivar depends on the situation and the location considering...

BIOPLEX Phase III, Teilprojekt: „Biodiversity and spatial complexity in agricultural landscapes under Global Change(BIOPLEX) and Biolog-Europa Coordination (Project)
Another focal point of research is 'Biodiversity and spatial complexity in agricultural landscapes under Global Change' (BMBF: BIOPLEX). This interdisciplinary project by the Universities of Gießen and Göttingen analyses the relation between biodiversity, spatial complexity and socio-economy in agricultural landscapes. In addition to species richness and community composition of important...

Investigation and assessment of any impacts of pingers (acoustic devices) on the hearing of porpoises in EU fisheries (Project)
Following up the investigations of the BMVEL pilot project on morphology and histology of harbor porpoise (Phocoena phocoena) ears, the aim of this study was to investigate potential anthropogenic noise impacts. Echolocation is the main sense in harbor porpoises and important for detection of food, predator avoidance, navigation and communication. Therefore, it is likely that pathological changes...
