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 integrating data on P:L across plant species. Here, using a standard laboratory protocol, present over 80 species’ concentrations values, evaluate collected by three We discuss general phylogenetic, phenotypic, behavioral, ecological trends observed may drive interactions; also future questions further strengthen field pollination ecology.

The diversity, abundance, and health of wild bees is jeopardized primarily by land-use modifications, among other global change drivers.Defining measuring in requires an integrative approach across disciplines.We use elements from chemistry, stoichiometry, ecology, physiology, pathology, genetics to (i) contribute a more comprehensive definition bee 'health', (ii) define framework linking with floral resource/nutritional landscapes through assessing species-specific nutritional niches.We suggest novel holistic for capturing combining field laboratory tools.Knowledge gained applying this will serve as blueprint stakeholders engaged pollinator conservation.

Pollen nutrition structures bee and plant community interactions

Proceedings of the National Academy of Sciences, Journal Year: 2024, Volume and Issue: 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.

Variations in Nutritional Requirements Across Bee Species

Frontiers in Sustainable Food Systems, Journal Year: 2022, Volume and Issue: 6

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 original experiments laboratory conditions to evaluate variations requirements. analyzed content eight blends, terms sterols total concentration profiles. Each blend was provided four model species: honey ( Apis mellifera ), bumblebees Bombus terrestris mason Osmia bicornis cornuta ). For each species, specific protocols were used monitor development weight, timing, survival) resource collection.

Abstract In recent years, bumblebees have increasingly been used to study various aspects of bee biology, ecology and evolution. They are now broadly accepted as tractable model species, complementary the domestic honey bees, for fundamental applied apidology. Here, we provide a brief history how bumblebee research developed since their domestication commercialisation crop pollination in 1990s. Bumblebees large social bees that can be kept trained lab year-round. easy manipulate track individually small colonies. These practical advantages offered new possibilities experimental research, leading major breakthroughs different fields such cognition, navigation, nutrition, host-parasite interactions, insect declines.
