Soil conditions and the emergence phenology and survival of a solitary, ground‐nesting bee in a coastal dune environment

open access: yesEcological Entomology, Volume 50, Issue 3, Page 514-522, June 2025.
For a solitary, ground‐nesting bee species in a mild coastal dune environment, emergence phenology was not influenced by soil moisture or temperature fluctuations. For a solitary, ground‐nesting bee species in a mild coastal dune environment, bee survival was not influenced by soil moisture or temperature fluctuations.

Up High, Hot and Dry: Individual Reproductive Output in Subalpine Bees Declines With Increasing Drought Severity

open access: yesGlobal Change Biology, Volume 31, Issue 6, June 2025.
Climate change has been linked to widespread changes in the distributions and abundances of many wild bee species; yet, the local‐scale processes that generate these patterns are unclear. From 2013 to 2022, we tracked individual reproductive output (brood cell production) in over 700 solitary female mason bees at seven sites in the Colorado Rocky ...

The Bees of A.L. Mangham Jr. Regional Airport, Nacogdoches, Texas [PDF]

open access: yes, 2017
The United States is home to about 4,000 species of native bees, and many are critically important due to the pollination services they provide (Buchman & Nabhan 1996). Most of these are inconspicuous, solitary bees that nest in the ground.

Modeling population dynamics of solitary bees in relation to habitat quality [PDF]

open access: yes, 2001
To understand associations between habitat, individual behaviour, and population development of solitary bees we developed an individual-based model. This model is based on field observations of <i>Osmia rufa</i> (L) (Apoideae: Megachilidae ...

Fitness costs and benefits of a non‐native floral resource for subalpine solitary bees

open access: yesOikos, Volume 2025, Issue 6, June 2025.
Organisms inhabiting seasonal environments must fit their life cycle into a limited time window while also synchronizing periods of resource consumption with timing of resource availability. Introduced non‐native species, which often differ in phenology from natives, can alter and expand the seasonal window of resource availability for native consumers,

Megachile (Megachile) montivaga (Hymenoptera: Megachilidae) nesting in live thistle (Asteraceae: Cirsium) [PDF]

open access: yes, 2015
Although Megachile Latreille (leafcutter bees) are well known for their diverse nesting habits, records of the genus nesting in live plants are rare.  Here, we report the widespread Megachile (Megachile) montivaga Cresson nesting in live thistle (Cirsium
