Relative importance of predators and parasitoids for cereal aphid control
Field experiments with manipulations of natural enemies of plant–feeding insects may show how a diverse enemy group ensures an important ecosystem function such as naturally occurring biological pestExpand
Increasing syrphid fly diversity and density in sown flower strips within simple vs. complex landscapes
Summary 1.  The structural complexity of agricultural landscapes influences the local biodiversity and associated ecosystem services. Hence, developing effective biodiversity management requires aExpand
Decomposition of beech leaves (Fagus sylvatica) and spruce needles (Picea abies) in pure and mixed stands of beech and spruce
Abstract The decomposition of spruce needles and beech leaves was investigated in a 30- and 120-yr-old beech, spruce and mixed (beech/spruce) forest using 1 mm mesh litterbags. The mass loss, contentExpand
Tradeoffs between income, biodiversity, and ecosystem functioning during tropical rainforest conversion and agroforestry intensification
Losses of biodiversity and ecosystem functioning due to rainforest destruction and agricultural intensification are prime concerns for science and society alike. Potentially, ecosystems showExpand
The soil fauna of beech forests: comparison between a mull and a moder soil
In comparison to moder conditions, the mull forest is characterized by higher species numbers, more equable rank-abundance relations, higher faunal biomass (approximately 15 g dry mass•m −2 ),Expand
Oribatid mite and collembolan diversity, density and community structure in a moder beech forest (Fagus sylvatica): effects of mechanical perturbations
Abstract The effects of mechanical perturbations on two soil microarthropod communities (oribatid mites and collembolans) were investigated in a moder beech forest on sandstone. We disturbed the soilExpand
Effects of plant diversity on Collembola in an experimental grassland ecosystem
The response of species numbers and density of Collembola to manipulation of plant species richness (1, 2, 4, 8, 32 species) and number of plant functional groups (grasses, legumes and non-legumeExpand
Nutrient release from decomposing leaf litter of temperate deciduous forest trees along a gradient of increasing tree species diversity
Abstract In the litter of six deciduous tree species ( Fagus sylvatica , Tilia spp., Fraxinus excelsior , Carpinus betulus , Acer pseudoplatanus and Acer platanoides ) and in stand-specific litterExpand
Life Cycles and Diapause
The developmental cycle of spiders concerns many aspects of morphology, physiology and ecology: embryogenesis and postembryonic growth, life cycle patterns, adaptation to seasonally occurring adverseExpand
The soil fauna of a beech forest on limestone: trophic structure and energy budget
SummaryThe soil fauna of a mull beech forest on lime-stone in southern Lower Saxony (West Germany) was sampled quantitatively. Biomass estimates, trophic characteristics, and measurement andExpand
