Journal of Biogeography, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 6, 2025

ABSTRACT Aim Insect brood parasites (i.e., cleptoparasites), like cuckoo bees, typically attack hosts within specific lineages, but seem to be less constrained by the biogeographical movements of their compared obligate parasites. Cuckoo bees depend on stable host populations, being particularly sensitive environmental changes and thus valuable bioindicators bee community health. We here test congruence between history oil hosts. Location The Americas. Taxon Bees (Hymenoptera, Apidae). Methods Using phylogenomic Sanger sequence data, we present new time‐calibrated phylogenies for in ericrocidine line hosts, Centris Epicharis. estimate ancestral ranges using six historical models a set 100 trees, randomly sampled from posterior distribution each group, accounting uncertainties divergence time estimates model selection. Results origin stem Cretaceous precedes cleptoparasite's Palaeocene. Cleptoparasite crown origins were synchronous Eocene, both took place tropical South America. While pair Rhathymini‐ Epicharis remained mostly associated this region, cleptoparasites expanded other parts Neotropical Nearctic regions independent range expansions events. In all cases, shifts preceded cleptoparasite shifts. Main Conclusion cleptoparasitic oil‐collecting is generally congruent space.

Host specificity of gut microbiota associated with social bees: patterns and processes

Microbiology and Molecular Biology Reviews, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

SUMMARYGut microbes provide benefits to some animals, but their distribution and effects across diverse hosts are still poorly described. There is accumulating evidence for host specificity (i.e., a pattern where different tend associate with distinct lineages), the causes consequences of this unclear. Combining experimental tests in laboratory broad surveys wild promising approach gaining comprehensive mechanistic understanding prevalence, origin, importance. Social bees represent an ideal testbed endeavor because they phylogenetically functionally diverse, host-specific, stable, tractable gut microbiota. Furthermore, western honeybee (Apis mellifera) emerging model system studying microbiota-host interactions. In review, we summarize data on prevalence strength social bee microbiota (bumblebees, stingless bees, honeybees), as well potential proven ecological molecular mechanisms that maintain specificity. Overall, found relatively strong likely results from several processes, including filtering mediated by immune priority effects. However, more research needed multiple species confirm these findings. To help future research, hypotheses field propose comparative tests. Finally, conclude review highlighting need understand how can influence health.

Environmental drivers of wild bee reproductive performance across a South American dryland ecoregion

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 292(2045)

Published: April 1, 2025

The reproductive performance of wild bees is a key determinant their population persistence. However, few studies have directly examined the environmental drivers demographic processes using geographically broad approach. In this study, we explored how biotic and abiotic factors influence reproduction solitary, cavity-nesting across Monte Desert ecoregion in Argentina. Using artificial nests standardized sampling spanning 2000 km 20° latitude, related metrics—nest establishment, offspring production survival—to climate (flower abundance, vegetation cover brood parasitism). Climate was strongest predictor bee performance: warm, humid conditions during nesting period were associated with reduced nest establishment survival. Brood parasitism further Across Desert’s latitudinal gradient, peaked at mid-latitudes, while survival increased towards higher latitudes. These general patterns matched those M. leucografa, most abundant species. findings highlight sensitivity to climatic conditions, particularly period. Our study advances our understanding potential impacts change on Neotropical bees, where extensive areas are experiencing dramatic land-use changes.

Climate explains global functional trait variation in bees

Functional Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: May 1, 2025

Abstract Climate is a fundamental driver of macroecological patterns in functional trait variation. However, many the traits that have outsized effects on thermal performance are complex, multi‐dimensional, and challenging to quantify at scale. To overcome this challenge, we leveraged techniques deep learning computer vision hair coverage lightness bees, using images diverse widely distributed sample museum specimens. We demonstrate climate shapes variation these global scale, with bee increasing maximum environmental temperatures (thermal melanism hypothesis) decreasing annual precipitation (Gloger's Rule). found deserts hotspots for bees covered light‐coloured hairs, adaptations may mitigate heat stress represent convergent evolution other desert organisms. These results support major ecogeographical rules emphasize role shaping phenotypic diversity. Read free Plain Language Summary article Journal blog.

Expanded phylogeny of Nomadinae (Hymenoptera: Apidae) with integration of UCE and DNA barcode sequence data

Insect Systematics and Diversity, Journal Year: 2025, Volume and Issue: 9(3)

Published: May 1, 2025

Abstract The apid subfamily Nomadinae is the oldest and most diverse clade of brood parasitic bees. Through incorporation data from a variety sources, we generated detailed taxonomically complete phylogeny this group to date. Despite differing amounts genetic available for different species, tree topology largely matched with expected relationships based on previous findings, 95% barcode-only taxa placed in consistent positions all tribes recovered as monophyletic. We further carried out divergence time estimation investigate evolutionary history place along geological scale, recovering an estimated age 99 Ma group. Testing effect dates indicated that ages deep nodes were robust, though inclusion such limited sequence tended push shallower towards older dates. Though approach may not be appropriate applications, potential integration cytochrome oxidase DNA barcode sequences modern phylogenomic (ultraconserved element) encouraging indication wealth previously published through repositories retains capacity informative future phylogenetic studies.

Abstract Aim To provide an assessment of climate change impacts on a set wild pollinators restricted to one the regions with greatest diversity bees in world. Also, we aimed test whether functional groups responded differently projections. Location South‐eastern South America (SES). Taxon Bees (Hymenoptera: Apidae sensu lato). Methods We selected 18 species mostly SES region, modelled their distributions and assessed possible near future (2050) richness shifts range centroids. Potential related different were evaluated through t ‐tests. Results was projected decrease northernmost increase southward. Most bee predicted shift centroids towards south‐west south, while suitable stable areas found southern Brazil. also higher proportional losses for eusocial compared solitary ones, generalists showed slightly lower gains than specialists. Main Conclusion are likely undergo changes future, at northern portions southward increases. The identified Brazil underscore importance conservation efforts particularly natural grasslands – endangered habitat high diversity. Although our results suggest vulnerability traditionally considered more resilient, it is essential acknowledge that other factors, including mutualists availability, behavioural particularities, phenology size, must be determinants ongoing change.

Biomechanical properties of non-flight vibrations produced by bees

Journal of Experimental Biology, Journal Year: 2024, Volume and Issue: 227(12)

Published: May 22, 2024

Bees use thoracic vibrations produced by their indirect flight muscles for powering wingbeats in flight, but also during mating, pollination, defence and nest building. Previous work on non-flight has mostly focused acoustic (airborne vibrations) spectral properties (frequency domain). However, mechanical such as the vibration's acceleration amplitude are important some behaviours, e.g. buzz where higher remove more pollen from flowers.

Host specificity and cophylogeny in the “animal-gut bacteria-phage” tripartite system

npj Biofilms and Microbiomes, Journal Year: 2024, Volume and Issue: 10(1)

Published: Aug. 27, 2024

Cophylogeny has been identified between gut bacteria and their animal host is highly relevant to health, but little research extended bacteriophages. Here we use bee model investigate specificity cophylogeny in the "animal-gut bacteria-phage" tripartite system. Through metagenomic sequencing upon different species, phageome revealed a more variable composition than bacteriome. Nevertheless, bacteriome showed significant association of dissimilarity matrices, indicating reciprocal interaction two kinds communities. Most phages were generalist at viral cluster level specialist OTU level. While dominant Gilliamella Snodgrassella exhibited matched phylogeny with hosts, most diminished cophylogeny. The evolutionary rates bee, remarkably increasing trend, including synonymous non-synonymous substitution gene content variation. For all three codiversified members, however, genes under positive selection involving gain/loss during evolution simultaneously enriched functions into metabolism nutrients, therefore highlighting coevolution that results an enhanced ecological fitness for whole holobiont.
