Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

open access: yesEcological Entomology, EarlyView.
In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...

Inhibition of the growth of Ascosphaera apis by Bacillus and Paenibacillus strains isolated from honey Inhibición del crecimiento de Ascosphaera apis mediante cepas de Bacillus y Paenibacillus aisladas de miel

open access: yesRevista Argentina de Microbiología, 2004
The fungus Ascosphaera apis, the causative agent of chalkbrood disease in honeybee larvae, occurs throughout the world and is found in many beekeeping areas of Argentina.

Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

open access: yesThe FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

open access: yesInsect Conservation and Diversity, EarlyView.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Mapping wild bee diversity and flower use for an effective conservation of the Doñana biodiversity hotspot

open access: yesInsect Conservation and Diversity, EarlyView.
We compiled the first checklist of wild bees in Doñana Protected Area, documenting 385 species, including three vulnerable and one endangered species listed in the Red List. Bee species exhibit diverse floral preferences, highlighting the need to incorporate plant–pollinator interactions and the role of plants in conservation and management strategies ...

Eight Years of Citizen Science Reveal Taxonomic Confusion Patterns and Dynamic Participation in the Monitoring of Vespa velutina in Spain

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The yellow‐legged hornet (Vespa velutina nigrithorax) is a successful invasive species in Europe, where its monitoring is partially reliant on citizen science (CS) initiatives. While CS is a powerful tool for early detection, taxonomic confusion and fluctuating participant engagement can limit its effectiveness.

Nanoparticles in Periodontology and Implant Dentistry: From Mechanisms to Clinical Applications

open access: yesJournal of Periodontal Research, EarlyView.
Nanotechnology holds significant promise in improving dental care, yet there is a need for more reliable clinical studies to validate its effectiveness and safety. ABSTRACT Recent advances in nanotechnology are reshaping the landscape of periodontology and implant dentistry, particularly through the application of nanoparticles (NPs).

Seeing Through an Ant's Eyes: Do Entomopathogenic Fungi Extend Their Cognition to Their Hosts?

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Post‐cognitivist approaches recognize cognition as a phenomenon that involves not just brains but all the sensorimotor apparatus of organisms. This means that brains are not always required for the emergence of cognition and that every organism can, in principle, be cognitive, unlocking a theoretical framework to explain the complex adaptive ...

Preschoolers’ Sensitivity to Abstract Relations Among Sets

open access: yesTopics in Cognitive Science, EarlyView.
Abstract In two studies, we test preschoolers’ ability to compare abstract relationships across sets. In Experiments 1a−1d, we show that both older (4‐ and 5‐year‐olds) and younger (3‐year‐olds) preschoolers successfully match both monotonic and symmetric relationships in visual patterns and succeed both in direct relational matches and inverted ones ...
