Soil Carbon Saturation Constrains Long‐Term Sequestration Under Revegetation on China's Loess Plateau

Earth's Future, Volume 14, Issue 7, July 2026.
Abstract Revegetation can enhance soil organic carbon (SOC) sequestration and contribute to climate change mitigation, yet the mechanism controlling long‐term sequestration remain insufficiently resolved, particularly with respect to particulate organic carbon (POC), mineral‐associated organic carbon (MAOC), and carbon saturation deficit (CSD).

Colletes

, 2012
Key to the Colletes species of Ukraine Males For the identification of males it is generally recommended and necessary for most species to dissect genitalia and especially S7. Due to variation in size and outer morphology the shape and size of S7 is the easiest and most reliable character for the identification of the majority of species.

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

Functional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Soil sand content is a driving force in structuring bee communities

Insect Conservation and Diversity, Volume 19, Issue 3, Page 675-685, May 2026.
We conducted a carefully designed observational study across three soil sand content categories using Dalea purpurea that attracts a wide range of bee species and grows in different soil types. Soil sand content, not floral resource availability, affected patterns of bee distribution, and contrary to expectations, sandier sites did not host the highest

Avocado crops as a floral resource for native bees of Chile

Revista Chilena de Historia Natural, 2020
Background Chile is the second largest avocado producer in the world. However, there have been few studies on interactions between native bees and avocado pollination in a Chilean environment.

DRD2 Deficiency Underlies Pituitary Adenoma Dependent on Escherichia coli Translocation from the Gut

Advanced Science, Volume 13, Issue 24, 27 April 2026.
Dopamine receptor D2 (DRD2) deficiency disrupts epithelial barrier integrity in both the gut and pituitary gland, facilitating translocation of gut‐derived Escherichia coli into pituitary tissue. Intratumoral E. coli are phagocytosed by microglia, triggering GSDMD‐dependent pyroptosis and HMGB1 release, which subsequently activates MAPK signaling to ...

Landscape and local factors influence solitary bee nesting, but reported effects show little consistency across studies

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Collectively, these findings indicate that agri‐environment schemes aiming to support solitary bees should integrate the provision of nesting resources with proximity to floral resources. The heterogeneity among studies highlights the need for solitary bee conservation measures to be tailored to local conditions and to the local fauna.

Using citizen science to examine the nesting ecology of ground‐nesting bees

Ecosphere, 2019
Suitable nest sites are a crucial habitat requirement of ground‐nesting bees, but empirical studies of fossorial solitary bee nesting ecology in the UK are few in number.
