Investigations of the use of biotechnological methods for the control of the horse chestnut leafminer in public parks (Project)
The objective of this project is to investigate three environmentally friendly methods (mating disruption, attract & kill and promotion of beneficials) to control the horse chestnut leafminer (Cameraria ohridella) in public green areas.

SFB 552: B6 - Carbon dioxide production in soils under cacao agroforestry and natural forests: effects of drought and landscape variability (Project)
The main goals of this sub-project are: * To estimate the effects of natural and experimental droughts and consecutive rewetting on the soil CO2 production and efflux in natural forest and cacao agroforestry ecosystems. * To identify the environmental controls on spatial variation in soil CO2 efflux in the natural forest during the wet and the dry season. Central hypotheses for the first goal of...

SFB 552: B7 - Drought Effects on Water Consumption and Plant Water Status of Trees in the Natural Forest (Project)
ENSO-related droughts can have a large influence on growth and vitality of trees in tropical moist forests. As part of the replicated throughfall displacement experiment in Focus 3, this subproject investigates the response of water consumption, hydraulic conductivity and plant water status of various tree species in the species-rich natural forest in the Toro region to applied mild and severe...

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)...

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...
