Widespread contamination of ecosystems with pesticides threatens non-target organisms. However, the extent to which life-history traits affect pesticide exposure and resulting risk in different landscape contexts remains poorly understood. We address this for bees across an agricultural land-use gradient based on assays pollen nectar collected by Apis mellifera, Bombus terrestris Osmia bicornis, representing extensive, intermediate limited foraging traits. found that extensive foragers (A. mellifera) experienced highest risk-additive toxicity-weighted concentrations. only (B. terrestris) (O. bicornis) responded context-experiencing lower less land.

As bees’ main source of protein and lipids, pollen is critical for their development, reproduction, health. Plant species vary considerably in the macronutrient content pollen, research bee model systems has established that this variation both modulates performance guides floral choice. Yet, how chemistry shapes interactions between plants bees natural communities an open question, essential understanding nutritional dynamics plant–pollinator mutualisms informing conservation. To fill gap, we asked nutrition (relative lipid content) sampled from 109 co-flowering plant structured visitation patterns observed among 75 subgenera pollen-collecting Great Basin/Eastern Sierra region (USA). We found degree similarity species’ predicted visitor communities, even after accounting morphology phylogeny. Consideration also shed light on structure interaction network: Bee genera were arranged into distinct, interconnected groups, delineated by differences values, revealing potential niches. Importantly, alone (high protein, high lipid, or balanced) did not predict diversity visitors, indicating offering complementary may be equally valuable supporting diversity. Nutritional should thus a key consideration when selecting habitat restoration, nutritionally explicit perspective needed considering reward involved community ecology pollination.

We investigated nutrition as a potential mechanism underlying the link between floral diversity/composition and wild bee performance. The health, resilience, fitness of bees may be limited by lack nutritionally balanced larval food (pollen), influencing entire population, even if adults are not availability quality their (mainly nectar). hypothesized that nutritional is indirectly connected to species diversity pollen provisions directly driven composition. Therefore, accessibility specific, desirable key plant for larvae might promote populations. Using fully controlled feeding experiment, we simulated different resources could available in various environments, reflecting changes composition caused landscape changes. Suboptimal concentrations certain nutrients produced specific resulted reduced fitness. negative effects were alleviated when scarce added these diets. scarcity was associated with but diversity. Thus, one mechanisms decreased homogenous landscapes imbalance, i.e., presence eaten larvae.

Agricultural management significantly affects insects, especially pollinators, which are crucial for crop pollination and biodiversity. In agricultural landscapes, various factors spanning different spatial scales known to affect pollinator health, which, in turn, can influence services. However, the importance of these driving health performance groups remains unclear. Using a long-term biodiversity research platform, German Biodiversity Exploratories, we investigated links between local landscape-level land-use, services common bumblebee Bombus lapidarius syrphid fly Episyrphus balteatus, by measuring traits as proxies Because their life histories, expected territorial bumblebees be more vulnerable land-use intensification at both levels, compared with migratory flies. Both environmental (climate) across affected mostly via changes body size: High intensity reduced size, whereas higher ambient air temperature decreased size.

The application of ionomics and ecological stoichiometry benefits conservation biology with necessary evolutionary relevance, allowing unresolved problems to be addressed. use enables consideration that changes in the environmental nutritional supply affect ecophysiology, behavior, health fitness individuals, influencing their interactions population functioning. resulting knowledge can help promote better restoration strategies. Ultimately, facilitate improved forecasting mitigation negative effects current global change. Here, we present theoretical background followed by biological conservation. We also propose avenues for future research. For example, larval adult pollinating insects belong different feeding guilds, larvae rely on various stoichiometrically (im)balanced foods (showing herbivory, pollinivory, detritivory or even carnivory). Therefore, ecology diversity pollinators may shaped quality food, which is required physiological development into fully functional adults.

Adult pollinators that forage primarily for energy have traditionally guided our understanding of plant–pollinator interactions, leading to assumptions about the importance different plants pollinators. Consequently, pollinator conservation strategies potentially overlook balance juvenile diets. I studied a representative bee, Osmia bicornis, explore contributions various nutritional quality diet.
