Pollinator nutritional ecology provides insights into plant–pollinator interactions, coevolution, and the restoration of declining pollinator populations. Bees obtain their protein lipid nutrient intake from pollen, which is essential for larval growth development as well adult health reproduction. Our previous research revealed that pollen to ratios (P:L) shape bumble bee foraging preferences among host-plant species, these preferred link colony fitness. Yet, we are still in early stages...
Larvae and imagos of bees rely exclusively on floral rewards as a food source but host-plant range can vary greatly among bee species. While oligolectic species forage pollen from single family host plants, polylectic bees, such bumblebees, collect many families plants. These contend with interspecific variability in essential nutrients their host-plants we have only limited understanding the way which chemicals chemical combinations influence development feeding behaviour. In this paper,...
Abstract Bumblebees are valuable pollinators of numerous wild and cultivated plants. They can forage on variable pollen resources. As some species lack particular nutrients or have global low nutritional quality, it has been suggested that bumblebees mix their incomes to ensure a balanced diet. The hypothesis mixed diet better supports bumblebee colony development than single poorly explored. We compared the impact mono‐, di‐ trifloral diets microcolony Bombus terrestris using three...

Pollinators are experiencing declines globally, negatively affecting the reproduction of wild plants and crop production. Well-known drivers these include climatic nutritional stresses, such as a change dietary resources due to degradation habitat quality. Understanding potential synergies between two important is needed improve predictive models future effects climate on pollinator declines. Here, bumblebee colony bioassays were used evaluate interactive heat stress, reduction resource...
Body size latitudinal clines have been widley explained by the Bergmann's rule in homeothermic vertebrates. However, there is no general consensus poikilotherms organisms particular insects that represent large majority of wildlife. Among them, bees are a highly diverse pollinators group with high economic and ecological value. Nevertheless, comprehensive studies species assemblages at phylogenetically larger scale carried out even if they could identify traits conditions generate different...
Abstract Human activities can generate a wide variety of direct and indirect effects on animals, which manifest as environmental genetic stressors. Several phenotypic markers have been proposed indicators these stressful conditions but displayed contrasting results, depending, among others, the trait measured. Knowing worldwide decline multiple bumblebee species, it is important to understand stressors link them with drivers decline. We assessed impact several (i.e. natural toxin-,...
Excessive pollen harvesting by bees can compromise the reproductive success of plants. Plants have therefore evolved different morphological structures and floral cues to narrow spectrum feeding visitors. Among "filtering" mechanisms, chemical mechanical protection might shape bee-flower interactions restrict exploitation a specific suite visitors such as observed in Asteraceae. Asteraceae is indeed only occasionally exploited generalist bee species but plentifully foraged specialist ones...
With 2,000 species currently recorded in Europe, bees are a highly diversified and efficient group of pollinating insects. They obtain their nutrients from nectar pollen flowers. However, the chemical composition these resources, especially (e.g., protein, lipid, amino acids, fatty or sterol content), is variable among plant species. While it well-known that show interspecific variation floral choices, there lack information on nutritional requirements different bee We therefore developed...
The Pleistocene climatic oscillations are considered as a major driving force of intraspecific divergence and speciation. During Ice Ages, populations isolated in allopatric glacial refugia can experience differentiation reproductive traits through selection regimes. This phenomenon may lead to isolation dramatically accentuates the consequences on species. Alternatively, when is incomplete expanding again, further mating between formerly result formation hybrid zone, genetic introgression...
Abstract Current evidence suggests that pollen is both chemically and structurally protected. Despite increasing interest in studying bee–flower networks, the constraints for bee development related to nutritional content, toxicity digestibility as well their role shaping of interactions have been poorly studied. In this study we combined bioassays generalist Bombus terrestris on Cirsium , Trifolium Salix Cistus genera with an assessment toxicity, pollen. Microcolonies showed significant...
Concentration of air pollutants, particularly ozone (O3), has dramatically increased since pre-industrial times in the troposphere. Due to strong oxidative potential O3, negative effects on both emission and lifetime atmosphere plant volatile organic compounds (VOCs) have already been highlighted. VOCs alteration by O3 may potentially affect attraction pollinators that rely these chemical signals. Surprisingly, direct olfaction behavioral response not investigated so far. We developed a...
Several bee species are experiencing significant population declines. As bees exclusively rely on pollen for development and survival, such declines could be partly related to changes in their host plant abundance quality. Here, we investigate whether generalist bumblebee species, with stable trends over the past years, adapted diets response distribution chemical quality of resources. We selected five common NW Europe which had a precise description diet through two time periods ('prior...
Chemical communication in insects' sexual interactions is well-known to involve olfaction of volatile compounds called sex pheromones. In theory, chemical may also chemicals with low or no volatility exchanged during precopulatory gustatory contacts. Yet, knowledge on this latter type so far mostly restricted the Drosophila fly model. Here we provide most comprehensive characterization date cuticular profile, including both and non-volatile compounds, a model butterfly, Bicyclus anynana....
Background Pollinating insects provide economically and ecologically valuable services, but are threatened by a variety of anthropogenic changes. The availability quality floral resources may be affected land use. For example, flower-visiting in agroecosystems rely on weeds field edges for foraging resources, these often exposed to agrochemicals that compromise the their resources. Methods We conducted complementary greenhouse experiments evaluate the: (1) effect low concentrations...
