Article
Background and Aims At the population level, genetic diversity is a key determinant of a tree species’ capacity to cope with stress. However, little is known about the relative importance of the different components of genetic diversity for tree stress responses. We compared how two sources of genetic diversity, genotype and cytotype (i.e. differen...
Article
Climate change is threatening the persistence of many tree species via independent and interactive effects on abiotic and biotic conditions. In addition, changes in temperature, precipitation, and insect attacks can alter the traits of these trees, disrupting communities and ecosystems. For foundation species such as Populus, phytochemical traits a...
Preprint
With advancing climate change, tree survival increasingly depends on mechanisms that facilitate coping with multiple environmental stressors. At the population level, genetic diversity is a key determinant of a tree species’ capacity to deal with stress. However, little is known about the relative relevance of the different components of genetic di...

Functional trait variation within individual plants is predicted to have important ecological consequences. However, our understanding of the sources contributing to subindividual trait heterogeneity, and the ramifications thereof, is poor. In a common garden, we sampled multiple genotypes of mature trembling aspen Populus tremuloides at different...
Article
BACKGROUND In its invaded regions, Drosophila suzukii (Matsumura) is a novel host for the community of resident parasitoids of Drosophila . To attain a high parasitization rate on the novel host, the parasitoids have to locate it and accept it in presence of other Drosophila hosts. We conducted a laboratory choice experiment and a semi‐field trial...

Background Besides fibers, cotton plants also produce a large amount of seeds with a high oil and protein content. The use of these seeds is restricted by their high contents of the terpenoid gossypol, which is harmful to humans and livestock. Using a genetic engineering approach, “Ultra-low gossypol cottonseed” (ULGCS) plants were produced by knoc...
Article
Full-text available
Bt cotton was genetically modified to produce insecticidal proteins targeting Lepidopteran pests and is therefore only minimally affected by caterpillar damage. This could lead to reduced levels of inherent, systemically inducible defensive compounds in Bt cotton which might benefit other important cotton herbivores such as plant bugs. We studied t...
Article
Full-text available
Phytochemical defense responses of plants are often herbivore-specific and can be affected by a herbivore’s feeding mode. However, comprehensive studies documenting the impact of multiple herbivores from different feeding guilds on induced phytochemical responses in distal leaves and its consequences for plant-mediated herbivore interactions are li...
Article
Full-text available
The transfer of plant-produced insecticidal Cry-proteins in the arthropod food web can be affected by a number of environmental and ecological factors. Despite this fact, most studies documenting multitrophic Cry-protein acquisition patterns in arthropods are conducted under controlled conditions whereas the number of field studies is limited. Such...
Article
Full-text available
In its defense against herbivores, cotton (Gossypium sp.) relies in part on the production of a set of inducible, non-volatile terpenoids. Under uniform damage levels, in planta allocation of induced cotton terpenoids has been found to be highest in youngest leaves, supporting assumptions of the optimal defense theory (ODT) which predicts that plan...
Article
Full-text available
Background: Insect-resistant transgenic plants that express insecticidal Cry proteins from Bacillus thuringiensis (Bt), are grown on millions of hectares worldwide. While these proteins are efficient in controlling key lepidopteran pests, not all pests are affected and the development of resistance in target pests is always a danger. These short-c...
Article
Full-text available
Cryptic species are phylogenetically diverged taxa that are morphologically indistinguishable and may differ in their ecological and behavioral requirements. This may have important implications for ecosystem services and conservation of biodiversity. We investigated whether two ecologically important cryptic species of the freshwater amphipod Gamm...
Article
In recent decades, the extent of primary forest in tropical regions has decreased drastically, with concurrent increases in the extent of tropical secondary forest. This has important implications for conservation management. We present novel data on species diversity and composition for three taxa (bats, geometrid moths and plants) in forests at t...
Article
Full-text available
Two forest plots that were thrown down by the storm Lothar on 26.12.1999 in the middle of a beech forest near Habsburg (and were since untouched) and two similar but unaffected plots near Brugg (AG) were compared between 14.4. and 27.6.2011 with respect to vegetation (with the Braun-Blanquet method) and nocturnal Macrolepidoptera. The latter were a...
