Global change and species interactions in terrestrial ecosystems.
TLDR
It is concluded that in order to reliably predict the effects of GEC on community and ecosystem processes, the greatest single challenge will be to determine how biotic and abiotic context alters the direction and magnitude of G EC effects on biotic interactions. Expand
Landscape moderation of biodiversity patterns and processes ‐ eight hypotheses
TLDR
This review uses knowledge gained from human‐modified landscapes to suggest eight hypotheses, which it hopes will encourage more systematic research on the role of landscape composition and configuration in determining the structure of ecological communities, ecosystem functioning and services. Expand
Conservation biological control and enemy diversity on a landscape scale
TLDR
Complex landscapes characterized by highly connected crop–noncrop mosaics may be best for long-term conservation biological control and sustainable crop production, but experimental evidence for detailed recommendations to design the composition and configuration of agricultural landscapes that maintain a diversity of generalist and specialist natural enemies is still needed. Expand
Habitat modification alters the structure of tropical host–parasitoid food webs
TLDR
Altered interaction structure represents an insidious and functionally important hidden effect of habitat modification by humans, indicating that perturbation of the structure and function of ecological communities might be overlooked in studies that do not document and quantify species interactions. Expand
Interactive effects of habitat modification and species invasion on native species decline.
TLDR
An interpretive framework is developed that will enable global change researchers to identify and discriminate between major interaction pathways, and formalises a distinction between numerically mediated versus functionally moderated causal pathways. Expand
Are invasive species the drivers of ecological change?
TLDR
In a new paper, MacDougall and Turkington provide the first direct test of whether invasive species are the drivers of community change, or merely 'passengers' along for the environmental ride. Expand
Functional group diversity of bee pollinators increases crop yield
TLDR
This study related differences in three functional traits of pollinating bees to the seed set of the obligate cross-pollinated pumpkin Cucurbita moschata Duch, leading to enhanced crop yield without any managed honeybees. Expand
Conservation of species interaction networks
TLDR
The attributes of web structure that are predicted to confer stability or increased function to a system, as these may be of greatest interest to conservation biologists are summarised. Expand
Spillover edge effects: the dispersal of agriculturally subsidized insect natural enemies into adjacent natural habitats.
TLDR
It is suggested that spillover of agriculturally subsidized insect natural enemies may be an important process affecting prey populations in natural habitat fragments, based on the ubiquity of agricultural-natural edges in human dominated landscapes and the clear importance of the landscape matrix in influencing predator impacts in agroecosystems. Expand
Food webs: reconciling the structure and function of biodiversity.
TLDR
The progression of food-web ecology and the challenges in using the food- web approach are summarized and five areas of research are identified where advances can continue, and be applied to global challenges. Expand
