Farmland heterogeneity effects on biodiversity, community traits and insect pollination
(2019-04-05)Agricultural intensification has led to severe biodiversity losses. One reason is the drastic reduction of (semi-)natural habitat, but there is also a global trend to reduced farmland heterogeneity due to larger field sizes ... -
Trophic interactions of ants, birds and bats affecting crop yield along shade gradients in tropical agroforestry
(2015-12-09)Tropical agroforests are diverse systems where several predator groups shape animal communities and plant-arthropod interactions. Ants, birds and bats in particular can reduce herbivores and thereby increase crop yield. ... -
Scale-dependent management of biodiversity and ecosystem processes in fragmented landscapes
(2015-10-06)Global biodiversity is increasingly found in fragmented landscapes and populations due to altered human land use. Expansion of agricultural land and changed agricultural practices to the detriment of natural and semi-natural ... -
Multitrophic interactions along a plant size gradient in Brassicaceae
(2015-02-19)Plant size is hypothesised to be a major driver of biotic interactions, as larger plants are more conspicuous and offer a wider range of resources and niches for associated animals. However, the role of interspecific ... -
Plant - Invertebrate Interactions in Agriculturally Managed Grasslands Under Functional Group Manipulation
(2013-12-12)Within the last few centuries the rapid growth of the human population, along with increasing economic development, has caused increasing demands for agricultural products such as food and fuel. This has led to an extension ... -
Services and disservices driven by ant communities in tropical agroforests
(2013-05-30)Agricultural productivity and human well-being are built upon ecosystem services and disservices. Ants in tropical agroecosystems drive a complex network of direct and indirect interactions between crops and their mutualists ... -
Pollinator biodiversity, functional complementarity and dynamic plant-pollinator interaction networks
(2012-11-06)Worldwide declines in biodiversity have prompted concerns about the functioning of ecosystems that may rely on it. This is also true for the pollination of plants, which is essential for the reproduction and thus long-term ... -
Agricultural intensification, biological pest control and spatio-temporal changes in food web structure
(2011-11-22)Agricultural intensification (AI) is a major driver of losses in agrobiodiversity and associated ecosystem functions such as biological control, thereby indirectly affecting agricultural ... -
Untersuchungen zu Spinnengemeinschaften in Kakaoagroforstsystemen in Indonesien: Diversität, Netzdichte und räumlich-zeitlicher Artenaustausch
(2010-10-22)Primary rainforests and the associated biodiversity are disappearing from tropical landscapes at accelerating rates due to agricultural expansion. Cacao agroforestry systems are commonly ... -
Below- and aboveground farmland biodiversity in relation to local and regional management
(2010-06-02)The expansion of global croplands, plantations and pastures in the last decades, which led to a dramatic change in the spatial structuring of agricultural landscapes is one of the main ... -
Spatiotemporal patterns of insect diversity and multitrophic interactions across a tree diversity gradient
(2008-12-12)Throughout the last decade, linking biodiversity with ecosystem functioning and services, such as pollination and biocontrol of pest species, has gained major attention in ecological research. ... -
Räumlich-zeitliche Auswirkungen der Landnuzung auf die Diversität von Bienen und Wespen.
(2006-03-17)Anthropogenic land use changes may have major consequences for global biodiversity and the functioning and stability of ecosystem processes. However, species diversity is determined by a ...
