Morphology and temporal evolution of ground-nesting bee burrows created by solitary and social species quantified through X-ray imaging

Geoderma, 2023
Most research on wild bees has focused on their role as pollinators, while their importance as soil ecosystem engineers has been largely overlooked, despite the fact that most species nest in the soil.

Notes on the Nests of \u3ci\u3eAugochloropsis metallica fulgida\u3c/i\u3e and \u3ci\u3eMegachile mucida\u3c/i\u3e in Central Michigan (Hymenoptera: Halictidae, Megachilidae) [PDF]

, 2017
Notes on the nesting biology of two ground-nesting species are provided from Central Michigan. A single nest of Augochloropsis metallica fulgida was excavated on 12 July 2014 in Shiawassee County. There were two female nest inhabitants.

The Bees among Us: Modelling Occupancy of Solitary Bees

PLOS ONE, 2016
Occupancy modelling has received increasing attention as a tool for differentiating between true absence and non-detection in biodiversity data. This is thought to be particularly useful when a species of interest is spread out over a large area and sampling is constrained.

Protecting an Ecosystem Service: Approaches to Understanding and Mitigating Threats to Wild Insect Pollinators [PDF]

, 2016
Insect pollination constitutes an ecosystem service of global importance, providing significant economic and aesthetic benefits as well as cultural value to human society, alongside vital ecological processes in terrestrial ecosystems.

Pesticide Exposure Assessment Paradigm for Solitary Bees [PDF]

Environmental Entomology, 2018
Current pesticide risk assessment for bees relies on a single (social) species, the western honey bee, Apis mellifera L. (Hymenoptera: Apidae). However, most of the >20,000 bee species worldwide are solitary. Differences in life history traits between solitary bees (SB) and honey bees (HB) are likely to determine differences in routes and levels of ...

Specificity Between Lactobacilli And Hymenopteran Hosts Is The Exception Rather Than The Rule [PDF]

, 2013
Lactobacilli (Lactobacillales: Lactobacillaceae) are well known for their roles in food fermentation, as probiotics, and in human health, but they can also be dominant members of the microbiota of some species of Hymenoptera (ants, bees, and wasps ...

Impact of Bee Species and Plant Density on Alfalfa Pollination and Potential for Gene Flow

Psyche: A Journal of Entomology, 2010
In outcrossing crops like alfalfa, various bee species can contribute to pollination and gene flow in seed production fields. With the increasing use of transgenic crops, it becomes important to determine the role of these distinct pollinators on alfalfa

Brain microRNAs among social and solitary bees [PDF]

Royal Society Open Science, 2019
ABSTRACT Evolutionary transitions to a social lifestyle in insects are associated with lineage-specific changes in gene expression, but the key nodes that drive these regulatory changes are unknown. We examined the relationship between social organization and lineage-specific microRNAs (miRNAs). Genome scans across 12 bee species showed

Conservation of solitary bees in power-line clearings: Sustained increase in habitat quality through woody debris removal

Global Ecology and Conservation, 2020
Declining populations of wild pollinators have increased the interest in the management of human-modified landscapes for pollinator conservation. Modified landscape features, such as power-line clearings, may provide valuable habitats with increased ...

Does the waggle dance help honey bees to forage at greater distances than expected for their body size? [PDF]

, 2015
A honey bee colony has been likened to an oil company. Some members of the company or colony prospect for valuable liquid resources. When these are discovered other group members can be recruited to exploit the resource. The recruitment of nestmates to a
