Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

Ibis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...

On the nomenclature of Bombus flavifrons Smith, 1866 (Hymenoptera, Apidae, Bombini) [PDF]

Journal of Hymenoptera Research
The name Bombus flavifrons has been applied to two different bumble bee species in North America, one described by Ezra Cresson in 1863, the other by Frederick Smith in 1866.

Is urbanisation a barrier to genetic diversity in the solitary specialist bee, Melissodes druriellus?

Insect Conservation and Diversity, EarlyView.
Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

Habitat and forage associations of a naturally colonising insect pollinator, the tree bumblebee Bombus hypnorum.

PLoS ONE, 2014
Bumblebees (Bombus species) are major pollinators of commercial crops and wildflowers but factors affecting their abundance, including causes of recent population declines, remain unclear.

Floral resource availability and surrounding land cover influence bumble bee community composition in an agricultural landscape

Insect Conservation and Diversity, EarlyView.
Multispecies occupancy models indicated that the occurrence of bumble bees was associated with local floral resources as well as the landscape surrounding a site within 1.6 km. Estimated species richness was greater at sites with more forest cover and lower at sites with more corn and soybean agriculture in the surrounding landscape.

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 ...

Dispersal mediates metapopulation response to local and regional stressors

Insect Conservation and Diversity, EarlyView.
A feature of recent insect declines is that widespread, formerly common species are among the worst affected. We designed a metapopulation simulation to ask how dispersal capability interacts with landscape and population stressors that act at different spatial scales.

Proteomic Characterization of the Venom of Five Bombus (Thoracobombus) Species

Toxins, 2017
Venomous animals use venom, a complex biofluid composed of unique mixtures of proteins and peptides, to act on vital systems of the prey or predator. In bees, venom is solely used for defense against predators.

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.
