Local and Landscape Management of Biological Pest Control in Oil Palm Plantations
(2016-06-14)Oil palm is the highest yielding vegetable oil crop per unit area and plantations expand at a rapid pace. Large-scale expansion of oil palm plantations, transformed from natural habitat, results in huge biodiversity losses. ... -
Bird Diversity, Functions and Services across Indonesian Land-use Systems
(2016-05-20)In tropical regions, rampant land-use conversion for agriculture threatens biodiversity hotspots. Forests are vanishing, and taxonomic diversity is severely affected by the transformation on a large scale. For mitigating ... -
Changing valuations of cultural ecosystem services along an urban-periurban gradient in Berlin
(2015-11-06)Urban green experiences high use-pressures through differing and conflicting demands. Eco-system services provided by urban green are manifold, with cultural ecosystem services (CES) representing socio-cultural benefits. ... -
Landscape context of habitat fragmentation and the diversity of plants, arthropods and snails on calcareous grasslands
(2015-04-10)Land-use change, habitat loss and fragmentation are among the main drivers of the decline of biodiversity worldwide. In Central Europe, calcareous grasslands belong to the most species-rich habitats. They harbour a great ... -
Local management and landscape context effects on bee pollination, ant seed predation, and yield in Indonesian homegardens
(2015-03-03)Tropical countries contribute substantially to global agricultural production, but the majority of farmers are small-scale subsistence farmers. Their comparably low agricultural productivity is coupled with major yield ... -
Scale dependence of pollinator community turnover and tritrophic interactions in changing landscapes
(2015-01-23)Agricultural landscapes account for approximately 40% of global terrestrial area and this proportion tends to grow due to the increasing demand for fuel, food and other agricultural products. For successful crop production ... -
Influence of grassland management on the abundance of the endophytic fungi Neotyphodium
(2014-11-26)The endophytic fungus Neotyphodium spec. Glenn, Bacon and Hanlin is common in many temperate grass species. This fungus is known to enhance the resistance of its host to adverse environmental conditions and to promote its ... -
Effects of management on biodiversity and productivity of grazed grassland
(2014-04-30)Grazing is seen as a promising tool to maintain and enhance biodiversity due to the creation of structurally diverse pastures. So far, grassland biodiversity has been studied in relation to various grazing management ... -
Birds, bats and arthropods in tropical agroforestry landscapes: Functional diversity, multitrophic interactions and crop yield
(2014-04-03)Ecosystem services such as the suppression of pest insects may increase productivity of agroforestry systems and thereby increase well-being of smallholders. Tropical birds and bats are effective predators of arthropods ... -
Scale- and trait dependent responses of bird communties to lowland rainforest restoration and frugivore-bird-seed interaction networks in Sumatra, Indonesia
(2014-02-10)Recovery of tropical secondary forest will require human assistance. The first important part in forest restoration is understanding the existing biodiversity and ecosystem service within the secondary forest and use this ... -
A regional view of an impending invasion: western corn rootworm development in Northern Germany
(2013-05-10)We examined the immature development of the invasive maize pest western corn rootworm (Diabrotica virgifera virgifera LeConte; WCR) under Northern German temperature regimes. This research was part of the Climate impact ... -
Bee pollination of strawberries on different spatial scales – from crop varieties and fields to landscapes
(2013-03-06)The global majority of our crops is dependent on pollination. Hence, pollination contributes to one third of global crop production and is an ecosystem service of high commercial and social importance. Bees are the most ... -
Local and landscape management effects on syrphid fly guilds: flower strips, farming practice and hedges
(2013-02-26)During the last decades, agriculture has transformed into highly effective and economically optimized production systems with extended cultivation areas and increased usage of fertilizers and pesticides. This development ... -
Plant-herbivore-predator communities and grassland management intensity - Implications for biodiversity conservation practices on local and landscape scales
(2013-01-23)The rapid growth of the human population and the concomitant demands for fuel, food and agricultural products put increasing pressures on ecosystems around the world. This has become a major driver of global environmental ... -
Ant community structure and biological control in Indonesian cacao agroforestry: long-term changes, land-use management and precipitation gradients
(2012-12-06)Land-use and climate change are the most important driver of biodiversity loss in terrestrial ecosystems. In agricultural habitats, intensification of agricultural management through the conversion to monocultures and ... -
Landscape context of bee, wasp and parasitoid diversity: grass-strip corridors, fallows and food webs
(2012-07-18)The world population is growing, resulting in an increasing demand for food and energy plants. During the last decades the modification of landscapes into agricultural production units and the intensification of agricultural ... -
Effects of agricultural management and manipulated plant species composition of permanent grassland on productivity and sward structure
(2012-05-04)The relationship between biodiversity and ecosystem functions of grasslands has received increasing attention in recent years. Scientists have sought to disentangle this complex relationship by sown biodiversity experiments ... -
Diversity and distribution patterns of foliar fungal endophytes in Theobroma cacao in Central Sulawesi and interactions between endophytes and host plant
(2012-04-24)Tropical plants are colonized by a highly diverse community of fungal endophytes. Factors contributing to fungal endophyte diversity pattern and underlying mechanisms are, however, largely unknown. Interactions between ... -
Plant-insect interactions in changing environments
(2010-08-18)Plant-insect interactions are essential to structure and functioning of terrestrial ecosystems. Shifts within interactions, or their removal from ecosystems due to human caused environmental ... -
The effects of the root endophytic fungus Acremonium strictum on plant-herbivore interactions
(2010-07-23)The widespread occurence of endophytic fungi in virtually all plant species has prompted an increasing number of investigations into the ecological significance of these cryptic microorganisms ...
