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...
ABSTRACT In honey bees (Apis mellifera), there is growing evidence that the impacts of multiple stressors can be mitigated by quality nutrition. Pollen, which primary source protein and lipids in bee diets, particularly critical for generating more resilient phenotypes. Here, we evaluated relationship between pollen to lipid (P:L) ratio insecticide resilience. We hypothesized diets richer would lead increased survival exposed insecticides, as pollen-derived have previously been shown improve...
ABSTRACT We used flowers to explore how ephemeral anthosphere microbiomes differ among flowering plant species and along an urban gradient. Here, we sequenced 16S rRNA for bacteria, ITS1 fungi rbcL DNA from 10 different sampled characterise gradient identify important network interactions. Bacterial fungal flower significantly differed in diversity across species, especially Asteraceae Fabaceae. Across all analyses, four taxa, the bacteria Pantoea Rosenbergiella Alternaria Cladosporium were...
Bees depend on flowering plants for their nutrition, and reduced availability of floral resources is a major driver declines in both managed wild bee populations. Understanding the nutritional needs different species, how these are met by varying provided plant taxa, can greatly inform land management recommendations to support populations associated ecosystem services. However, most nutrition research has focused three commonly commercially reared taxa—honey bees, bumble mason bees—with...
Fungicides are frequently used during tree fruit bloom and can threaten insect pollinators. However, little is known about how non-honey bee pollinators such as the solitary bee, Osmia cornifrons, respond to contact systemic fungicides commonly in apple production bloom. This knowledge gap limits regulatory decisions that determine safe concentrations timing for fungicide spraying. We evaluated effects of two (captan mancozeb) four translaminar/plant (cyprodinil, myclobutanil, penthiopyrad,...
Abstract Characterizing the nutritional needs of wild bee species is an essential step to better understanding biology and providing suitable supplemental forage for at‐risk species. Here, we aim characterize a model solitary species, Osmia cornifrons (Radoszkowski), by using dietary protein‐to‐lipid ratio (P:L ratio) as proxy niche breadth. We first identified mean target P:L (~3.02:1) collection range (0.75–6.26:1) from pollen provisions collected across variety sites time points. then...
Abstract Host plants required by specialist bee species may be limited in urban areas. We investigated the effects of urbanisation on Heriades truncorum , a solitary that is plant family Asteraceae. examined brood cell number, host and native pollen proportions (via DNA metabarcoding) nutritional composition provisions H. nests. Increasing resulted fewer cells higher genus diversity provisions. Bees collected from non‐native non‐Asteraceae genera, including new records for . overall was...
