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. Pesticide correlated among bee species between food sources was greatest A. mellifera-collected pollen-useful information future postapproval monitoring. provide trait- landscape-dependent occurrence, concentration identity encounter estimate risk, is necessary more realistic assessment essential tracking policy goals reduce risk.

Pollen nutrition structures bee and plant community interactions

Proceedings of the National Academy of Sciences, Год журнала: 2024, Номер 121(3)

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. Accordingly, provide conceptual representation how can impact populations affecting fitness-related life history traits. Additionally, suggest mixes 'bee-friendly' plants used improve base should composed considering local flora supplement vital considered environment.

Local and landscape factors differently influence health and pollination services in two important pollinator groups

The Science of The Total Environment, Год журнала: 2025, Номер 959, С. 178330 - 178330

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. Increasing proportions intensively managed areas landscape level viral infections species. Additionally, climate changed cuticular chemical profile, is essential communication social insects. intensive had an indirect negative effect on flower cover Pollination species were linked Thus, differently: intensification, while flies resilient potentially due mobility. As services, our results indicate that poses high risk crops pollinated small home ranges.

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. Although a stoichiometric balance during crucial pollinator fitness, focused needs Another example atmospheric CO2 increases leading nutrient dilution plant tissues, aggravating imbalances consumers challenging Earth's herbivore populations. CO2-driven food webs, ecosystems human wellbeing. However, our understanding this phenomenon minimal. These other studied solved using stoichiometry.

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. Using ecological stoichiometry and micronutrient ecology, investigated proportions vital body-building chemical elements (C, N, P, S, K, Na, Ca, Mg, Fe, Zn, Mn Cu; henceforth "nutrients") in larval pollen loads. considered botanical origin, location sexual dimorphism niche as factors influencing nutrient Redundancy analysis indicated main factor determining proportion was which accounted 70.17% variation; contributed 20.21%, sex 8.43%. Among 30 taxa composing loads, determinants content were oak, maple, chestnut, cabbage family, buttercup, grasses. Trees wind-pollinated provided important nutrients. Oak maple contributors nutrients essential growth body development (N, Cu, Zn). Grasses buttercups is bees.

Furthermore, our results indicated focal success, being overall stronger those at than scale. Floral influenced nest.
