Honeybees’ foraging choices for nectar and pollen revealed by DNA metabarcoding

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Sept. 7, 2023

Abstract Honeybees are the most widespread managed pollinators of our food crops, and a crucial part their well-being is suitable diet. Yet, we do not know how they choose flowers to collect nectar or pollen from. Here studied forty-three honeybee colonies in six apiaries over summer, identifying floral origins honey hive-stored samples by DNA-metabarcoding. We recorded available flowering plants analyzed specialized metabolites honey. Overall, find that honeybees use mostly same for both pollen, yet per colony less than half plant genera used at time. Across samples, on average fewer were but composition was more variable among suggesting higher selectivity sources. Of plants, only fraction either foraging. The time summer guided choices most, location impacted selected metabolite Thus, selective implicating need wide variety resources an optimal diet

A continuous feast of bramble: Rubus fruticosus agg. is a key cross‐seasonal dietary resource for a fallow deer population

Ecological Solutions and Evidence, Journal Year: 2025, Volume and Issue: 6(1)

Published: Jan. 1, 2025

Abstract Context : Deer (Cervidae) populations are increasing in many global regions, leading to concerns about their impacts on temperate forests. Advancing evidence‐based management requires a detailed understanding of the dietary habits deer and how these shaped by resource availability. Methodology We studied diet fallow ( Dama dama ) North Wales (United Kingdom), using faecal DNA metabarcoding. Samples were collected monthly from three woodlands during 2019–2021. Tree surveys seasonal ground flora conducted seven additional woodlands. Preference analyses used assess consumption plant taxa relative Results The consumed high proportions bramble Rubus fruticosus agg.) across seasons, especially winter months. Diet diversity was significantly lower compared other suggesting that bulk foraging widely available, predictable conserve energy winter. Grasses did not form major component any season. preference analysis showed spatially clustered woody (e.g. Betula sp., Corylus sp.

Ten‐a‐day: Bumblebee pollen loads reveal high consistency in foraging breadth among species, sites and seasons

Ecological Solutions and Evidence, Journal Year: 2024, Volume and Issue: 5(3)

Published: July 1, 2024

Abstract Pollen and nectar are crucial resources for bees but vary greatly among plant species in their quantity, nutritional quality timing of availability. This makes it challenging to identify an appropriate range plants meet the needs throughout year, though this information is important design pollinator conservation schemes. Using DNA metabarcoding pollen loads, we record floral resource use UK farmland bumblebees at different stages colony lifecycle, compare with null models ‘expected’ based on landscape‐scale availability (pollen nectar), foraging priorities preferences. We approach ask three main questions: (i) what breadth individual bumblebees?; (ii) do utilise a greater or lesser diversity than expected if they foraged proportion availability?; (iii) which preferentially utilise? Individual from highly consistent number taxa (mean: 10 ± 0.37 SE per bee), regardless species, sampling site time year. high consistency breadth, despite large changes identity availability, implies strong behavioural tendency towards fixed resources. effect was most striking April when maintained very low landscape‐level diversity. Bumblebees used some significantly more predicted abundance, supply, implying certain desirable characteristics beyond mere quantity resource. These included Allium spp. Vicia April; Trifolium repens Lotus corniculatus July Cardueae (thistles) Taraxacum officinale September. Practical implication : Our results strongly indicate that not only factor driving bumblebee patterns also factors. Thus, addition providing quantities resources, recommend schemes focus sufficient preferred enabling pollinators self‐select diverse nutritious diet.
