Understanding the distribution of pesticides in floral landscape is critical for land managers and regulators, particularly since identifying where exposure occurs to pesticide mitigation. In this study, we developed a bee-plant network commercial sweet cherry (Prunus avium L.) system surrounding unmanaged habitat. We estimated contamination flowering plants by trapping pollen from honey bee colonies, plant species origin pollen, relating non-Apis visitation toxicity detections. Over 90 plant-bee interactions were matched with collected pollen. By combining data, attributed hazard 33 genera. Unlike previous studies, observed greatest bees did not come visits crop or drift off orchard, but an orchard understory (genus Taraxacum). The importance was related both frequency bees. Our findings caution against generalizing how become exposed pesticides.

Antioxidant Capacity, Phytochemicals, Minerals, and Chemical Pollutants in Worker Honey Bee (Apis mellifera L.) Broods from Northern Thailand: A Safe and Sustainable Food Source

Honey bee brood (HBB) (Apis mellifera L.), a traditional protein source, has been studied for its nutritional value, but bio-functional properties and safety concerns have not verified. This study examined the Antioxidant capacity, phytochemicals, minerals, chemical pollutants in worker broods from several apiaries Northern Thailand. HBB samples were lyophilized to evaluate antioxidant capacity using ABTS, DPPH, FRAP assays, tests with water, 70% ethanol extracts. Phytochemicals identified LC-QTOF-MS; analyzed chromatographically, minerals determined ICP-OES. The results showed that evaluated of extracts included DPPH 2.04–3.37 mg/mL, ABTS 21.22–33.91 50.07–104.15 mg AAE/100 g dry weight. Water had outstanding activities except 10.67–84.97 9.25–13.54 57.66–177.32 mgAAE/100 Total phenolics flavonoids ranged 488.95–508.87 GAE/100 4.7–12.98 QE/g weight, respectively. Thirteen phytochemicals detected contained adequate mineral contents HBBs different locations found, which K, Ca, Mg, Na, no heavy metals or exceeded safe levels. These imply Thailand is nutritious food source considerable antioxidants sustainable source.

Existing flower preference metrics disagree on best plants for pollinators: which metric to choose?

Abstract When planting flowers for pollinator conservation, determining what to plant is challenging because flower establishment can be time‐consuming and resource‐intensive. To alleviate this challenge, researchers have proposed methods mathematically determine from plant–pollinator interaction data which species pollinators prefer, defined as the likelihood that a will chosen by when offered on an equal basis with other species. We compared lists produced five sensible, peer‐reviewed preference metrics calculated same dataset examined how each metric controls abundance relates number of visits. found little correlation between ranked returned varied in extent they controlled provided different information than The discordance among partially due way suggests these need empirically tested more research needed into factors impact floral preference. discourage use three (confidence interval, resource mass action hypothesis metrics), caution against one (centrality metric) recommend index its insensitivity insufficient sampling, ease fact it not correlated

Pollinator intraspecific body size variation and sociality influence their interactions with plants

Abstract Species morphological and behavioural traits are key determinants of which pollinator species interact with plant species. However, individuals within not identical in their this diversity could help us understand plant–pollinator interaction patterns. Using three independent data sets, we assessed whether bee intraspecific body size variation (ITV) sociality influenced specialisation, niche partitioning, centrality the network phylogenetic plants visited. We found that solitary pollinators were more specialised interactions had lower partitioning compared to social pollinators. Furthermore, higher ITV visited a ITV, whereas opposite pattern emerged for Pollinator did differ between Our findings show effect on depends sociality.

Background Land management change towards intensive grazing has been shown to alter plant and pollinator communities the structure of plant-pollinator interactions in different ways across world. Land-use intensification Eastern Europe is shifting highly diverse, traditionally managed hay meadows pastures, but few studies have examined how this influences networks. We hypothesized that effects on networks will depend their floral traits change. Methods investigated diversity composition near Sibiu, Romania at sites were as or pastures. quantified identity abundance flowering plants, used transect walks observe genera interacting with species. evaluated diversity, several indices network structure.

Biodiversity measures of a grassland plant-pollinator community are resilient to the introduction of honey bees (Apis mellifera)

PLoS ONE, Год журнала: 2024, Номер 19(10), С. e0309939 - e0309939

The prairies of Canada support a diversity insect pollinators that contribute pollination services to flowering crops and wild plants. Habitat loss use managed has increased conservation concerns for pollinators, as mounting evidence suggests honey bees (Apis mellifera) may reduce their abundance. Plant-pollinator community analyses often omit non-bee which can be valuable contributors services. Here, we experimentally introduced examine how abundance affects the species richness, diversity, abundance, composition, interaction all four higher taxa separately. We identified analyzed bee affected above biodiversity metrics, controlling flower richness. Even with high densities, there was no change any these variables, except beetle increased. All other had significant relationship Considering widespread bees, effect they have on should firmly established. Our results suggest little short-term impact pollinator or its interactions plants in this native grassland.
