Macronutrient composition in pollen affects development and survival in wild bees
Physiological Entomology, Volume 51, Issue 2, Page 350-362, June 2026.Small carpenter bees (Ceratina calcarata) were reared on diets formulated with black poplar and dandelion pollen, while closely monitoring developmental metrics, lipid content and survival. Macronutrient analyses on both pollen types revealed dandelion pollen contained lower levels of protein, essential amino acids and several fatty acids, which ...

Ecology and Evolution, Volume 16, Issue 5, May 2026.The first regional survey of spontaneous plant communities across 17 cities on the Qinghai‐Tibet Plateau shows that natural climatic conditions, especially precipitation and wind speed, are the primary drivers of variation in community diversity, while urbanization and habitat quality jointly structure plant community composition.

Fine‐Scale Temporal Dynamics of the Honey Bee Hive Microbiome and Foraging Revealed by Airborne eDNA
Environmental DNA, Volume 8, Issue 3, May–June 2026.Airborne eDNA collected within honey bee hives reveals diverse plant and microbial communities. While richness remains stable, seasonal shifts in plant and microbiome composition highlight dynamic resource use, demonstrating eDNA's potential for non‐invasive, fine‐scale monitoring of foraging and colony health. ABSTRACT Environmental DNA (eDNA) has the

Investigation on Flow Resistance of Large‐Scale Channels With Unmanaged Spontaneous Vegetation
Hydrological Processes, Volume 40, Issue 5, May 2026.The hydraulic measurements of two surveys (November 1995 and June 1996) by Flippin‐Dudley et al. were used. A theoretical flow resistance equation was assessed for a large‐scale vegetated channel. The analysis demonstrated that the theoretical flow resistance equation allows an accurate estimate of the Darcy–Weisbach friction factor.
