Body Size Variation in a Social Sweat Bee, Halictus ligatus (Halictidae, Apoidea), across Urban Environments [PDF]

Insects, 2021
High morphological variation is often associated with species longevity, and it is hypothesized that urban-dwelling species may require more plasticity in functional traits such as body size in order to maximize fitness in heterogeneous environments ...

Identification of 24 new microsatellite loci in the sweat bee Lasioglossum malachurum (Hymenoptera: Halictidae) [PDF]

BMC Research Notes, 2017
Objective The objective here is to identify highly polymorphic microsatellite loci for the Palaearctic sweat bee Lasioglossum malachurum. Sweat bees (Hymenoptera: Halictidae) are widespread pollinators that exhibit an unusually large range of social ...

100 Ma sweat bee nests: Early and rapid co-diversification of crown bees and flowering plants. [PDF]

PLoS ONE, 2020
100 Ma sweat bee nests reported herein are the oldest evidence of crown bees. A new phylogeny for short-tongued bees, calibrated with these nests dated with 40Ar/39Ar, attests for the first time for a late Albian rapid diversification of bees along with ...

Genetic differentiation at extreme latitudes in the socially plastic sweat bee Halictus rubicundus. [PDF]

PLoS ONE
The sweat bee Halictus rubicundus is an important pollinator with a large latitudinal range and many potential barriers to gene flow. Alongside typical physical barriers, including mountain ranges and oceans, the climate may also impose restrictions on ...

Morphological and Ecological Traits Explain Variation in Desiccation Tolerance Among Bees. [PDF]

Ecol Evol
We assessed the desiccation tolerance in 22 bee species from the Greek island of Lesbos. Larger bees lost water more slowly and survived longer, while survival declined with increasing water loss rate and water content at mortality. Morphological and ecological traits shaped physiological responses, highlighting trait‐based mechanisms underlying ...

Spatiotemporal variability and foraging behavior of bee visitors to a rare long-lived iteroparous forb, Silene spaldingii (Caryophyllaceae) [PDF]

Scientific Reports
Silene spaldingii S Watson is a rare long-lived forb (Caryophyllaceae) found primarily in open native grasslands of the Inland Pacific Northwest and is putatively pollinated by one key bumble bee pollinator, Bombus fervidus (Fabricius).

Soil salinity effects on pollen and pollinator visitation in a buzz-pollinated glycophyte, Solanum carolinense. [PDF]

Am J Bot
Abstract Premise Human activity has significantly altered the salt cycle, affecting an estimated 2.5 billion acres of soil worldwide. Elevated soil salinity is a well‐known plant stressor, but it may also affect interactions between plants and insects, which are often sodium limited.

The Significance of Genetic Relatedness and Nest Sharing on the Worker‐Worker Similarity of Gut Bacterial Microbiome and Cuticular Hydrocarbon Profile in a Sweat Bee [PDF]

Ecology and Evolution
The cuticular hydrocarbon (CHC) profile and the gut microbiome (GM) are crucial traits which have a significant impact on the life of bees. In honey bees, the CHC profile and the GM interact finely through trophallaxis, such that the characteristics of ...

Host identity, more than elevation, shapes bee microbiomes along a tropical elevation gradient [PDF]

Frontiers in Microbiology
Understanding how host-microbiome interactions respond to abiotic and biotic factors is key to elucidating the mechanisms influencing ecological communities under current climate change scenarios.
