Einstein–Bumblebee-dilaton black hole solution
European Physical Journal C: Particles and Fields, 2023 We obtain new black hole solutions in a Einstein–Bumblebee-scalar theory. By starting with a Einstein–Bumblebee theory in ( $$D+d$$ D + d ) dimensions, the scalar dilaton field and its interaction with the gravitational and Bumblebee fields are obtained ...

Spatial Relation of Bumblebees (Hymenoptera-Apidae) with Host-Plant and their Conservation Issues: An Outlook from Urban Ecosystem of Kathmandu Valley, Nepal [PDF]
, 2019 Ecology and conservation status of bumblebee species remains poorly understood, especially in rapidly degrading urban ecosystems, which is important considering the role of bumblebees in the pollinations. We collected more than 200 bumblebee (Bombus

Level of Genetic Diversity in European Bumblebees is Not Determined by Local Species Abundance
Frontiers in Genetics, 2019 Bumblebee species with declining population trends tend to show lower genetic diversity levels than stable species. The observed difference might be explained by abundance differences, with declining bumblebee species having lower genetic diversity ...

Flower Associations of Mimetic Syrphidae (Diptera) in Northern Michigan [PDF]
, 2017 Collections of specialized (high fidelity) mimetic Syrphidae in northern Michigan revealed 19 species associated with 18 flowering plants. Almost 97% of these syrphids were taken on seven plant species or species groups, all with conspicuous white or ...

The potential of electricity transmission corridors in forested areas as bumblebee habitat [PDF]
Royal Society Open Science, 2016 Declines in pollinator abundance and diversity are not only a conservation issue, but also a threat to crop pollination. Maintained infrastructure corridors, such as those containing electricity transmission lines, are potentially important wild ...

, 2010 Since bumblebees are a group associated with cool climates, Britain supports a large proportion (~10%) of the world's bumblebee fauna. However, three of our 25 species have become extinct, and seven species are Biodiversity Action Plan (BAP) listed, a higher proportion than for any other insect group.

Lipolytic Activity of a Carboxylesterase from Bumblebee (Bombus ignitus) Venom
Toxins, 2021 Bee venom is a complex mixture composed of peptides, proteins with enzymatic properties, and low-molecular-weight compounds. Although the carboxylesterase in bee venom has been identified as an allergen, the enzyme’s role as a venom component has not ...
