Susceptibility of solitary bees to agrochemicals highlights gaps in bee risk assessment

Environmental Toxicology and Pharmacology
Ground-nesting solitary bees are the most abundant bee species in the xeric areas of the world, but the effects of agrochemicals on them have been little studied. Herein, we evaluated the topical toxicity of an insecticide, a herbicide, and an essential oil on Mediterranean ground-nesting bees (Andrena impunctata, A. nigroolivacea, A.

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

Insect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

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

Insect 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 ...

Local habitat, not landscape diversity, drives richness and reproduction of cavity‐nesting bees and wasps in agricultural landscapes

Insect Conservation and Diversity, EarlyView.
Local habitat type and hedgerow cover strongly shape bee and wasp richness, but only weakly their reproductive output, outweighing the landscape diversity effects at the 1‐km2 scale. Forests host more wasp but fewer bee species, whereas orchards support high richness of both; bee reproduction patterns are driven by one dominant species, while wasp ...

Food resources are more important than nesting resources for explaining wild bee diversity in urban gardens Nahrungsressourcen haben einen größeren Einfluss auf die Wildbienendiversität in urbanen Gärten als das Nistangebot

Insect Conservation and Diversity, EarlyView.
Urban community gardens showed a high wild bee diversity with 168 recorded species, representing roughly 30% of Germany's wild bees, including threatened species like Osmia mitis and Coelioxys lanceolata. Floral resources, not nesting resources or habitat availability, were the main drivers for wild bee taxonomic and functional diversity.

Use of Social Bees and Solitary Bees as Bioindicators of Environmental Contamination

International Journal For Multidisciplinary Research
With an emphasis on the biology of bee nesting, their ecological functions, and their efficacy in determining heavy metal pollution, this review paper summarises current research on bees as bioindicators of environmental contamination. Review brought attention to the solitary nesting behaviours of species such as Epanthidium tigrinum and Megachile ...

Unequal pollinator benefits from partial mowing regimes in a field experiment

Insect Conservation and Diversity, EarlyView.
Pollinators aggregate in unmown refuges in partially mown vegetation in the first days after mowing. Up to four weeks after mowing, this initial aggregation is followed by a subsequent decline in abundance not observed in unmown locations. This decline is paired with a species richness decrease, revealing that partial mowing filters pollinator ...

Solitary bee larvae modify microbial diversity of pollen provisions in the stem-nesting bee, Osmia cornifrons (Megachilidae)

, 2022
In this study, we set out to explore how solitary bee larvae impact the brood cell microbiome in a common, easily manipulated, solitary, stem-nesting bee, Osmia cornifrons (Megachilidae).

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Teleosemantics for neural word embeddings

Mind &Language, EarlyView.
This paper applies a consumer‐based teleosemantic framework to give a detailed analysis of a particular algorithm for generating word embeddings. In the process, it addresses several of the challenges facing teleosemantic approaches to artificial neural networks.
