Abstract The land‐sharing versus land‐sparing debate recently stagnated, lacking an integrating perspective in agricultural landscapes as well consideration of ecosystem services. Here, we argue that (i.e. wildlife‐friendly farming systems) and separation high‐yielding agriculture natural habitats) are not mutually exclusive, both needed to balance management needs for the multifunctionality landscapes. Land‐sharing promotes services settings, thereby allowing environmentally friendly...
Abstract Pollinator declines in agricultural landscapes are driven by multiple stressors, but potential interactions of these remain poorly studied. Using a highly replicated semi‐field study with 56 mesocosms varying wild plant diversity (2–16 species) and oilseed rape treated neonicotinoid, we tested the interacting effects resource insecticides on reproduction solitary bee. Compared to monocultures, availability resources from plants complementing doubled brood cell production. In...
Bees are the most important group of insect pollinators, but their populations declining. To gain a better understanding wild bee responses to different stressors (e.g. land-use change) and conservation measures, regional national monitoring schemes currently being established in Germany, which is used here as model region, many other countries. We offer perspectives on how best design future programs with focus evaluating implementation measures. discuss traditional novel sampling methods,...
Abstract In the European registration process, pesticides are currently mainly tested on honey bee. Since sensitivity data for other bee species lacking majority of xenobiotics, it is unclear if and to which extent this model can adequately serve as surrogate all wild bees. Here, we investigated effects field-realistic contact exposure a pyrethroid insecticide, containing lambda-cyhalothrin, seven ( Andrena vaga , Bombus terrestris Colletes cunicularius Osmia bicornis cornuta, Megachile...
Abstract Agricultural intensification and the subsequent fragmentation of semi-natural habitats severely restrict pollinator pollen movement threatening both plant species. Linear landscape elements such as hedgerows are planted for agricultural conservation purposes to increase resource availability habitat connectivity supporting populations beneficial organisms pollinators. However, may have unexpected effects on persistence by not just channeling pollinators along, but also restricting...
In Central Europe, agricultural intensification has led to increasing fragmentation and loss of semi-natural habitats. turn, ecosystem services such as pollination are being lost when insect pollinators depend on Calcareous grasslands a highly threatened, biodiverse type habitat that may substantially support wild surrounding Here, we studied spillover from calcareous grassland fragments different sizes into the landscape for solitary social bees, well hoverflies. We selected eight varying...
Globally, high amounts of food are wasted due to insufficient quality and decay. Although pollination has been shown increase crop quality, a possible impact on shelf life not quantitatively studied. We tested how life, represented by fruit decay, firmness weight, changes as function limitation in two European, commercially important strawberry varieties. Pollination resulted lower deformed fruits. Whereas 65% wind-pollinated fruits were deformed, open only 20% During storage, the proportion...
Abstract Habitat loss is a primary driver of biodiversity decline, but differences in species responses to habitat from local landscape scales are poorly understood. Trophic level, food and specialization have been suggested be important predictors loss, diversity scale. Using cavity‐nesting communities bees, wasps their parasitoids on calcareous grasslands as model system allowed us compare differing regarding trophic degree food. We found that higher levels experienced semi‐natural at...
