Tropical Bee Assemblage Diversity Decreases With Elevation While Body Size Increases

open access: yesBiotropica, Volume 58, Issue 4, July 2026.
Photos of bee specimens collected in the Colombian Andes across a nearly 3000 m elevational cline. They are arranged to illustrate both the decline in richness with elevation and the increase in community average body size with elevation. ABSTRACT Elevation gradients are powerful drivers of changes in species composition, richness, and functional ...

Large Trees in Tropical Dry Forest Facilitate the Presence of Stingless Bee Nests (Apidae: Meliponini): The Case of Ficus crocata

open access: yesSociobiology
Stingless bees are a crucial pollinator group for the functioning of tropical ecosystems. While most species nest in tree cavities, the importance of different tree species for nesting bees remains poorly understood.

Insects and Survival: A Review of Primary and Secondary Defense Strategies

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

The Physicochemical Parameters, Phenolic Content, and Antioxidant Activity of Honey from Stingless Bees and Apis mellifera: A Systematic Review and Meta-Analysis

open access: yesAntioxidants
The most common bee species used for honey production is Apis mellifera (A. mellifera), followed by stingless bees. This study included scientific articles using the PRISMA approach.

Loss and Gain of Gut Bacterial Phylotype Symbionts in Afrotropical Stingless Bee Species (Apidae: Meliponinae)

open access: yesMicroorganisms, 2021
Stingless bees (Apidae: Meliponini) are the most diverse group of corbiculate bees and are important managed and wild pollinators distributed in the tropical and subtropical regions of the globe. However, little is known about their associated beneficial

The Wonders of Vanilla: Celebrating the 150th Anniversary of Synthetic Vanillin

open access: yesChemFoodChem, Volume 2, Issue 2, June 2026.
The year 2024 marked the 150th anniversary of the first commercial production of vanillin, one of the world's most cherished flavor ingredients. This review traces vanilla's history from Mesoamerica to modern production methods, examines its composition, the discovery of vanillin and Haarmann's early synthesis compared to modern methods, and highlights

Within-bloom shift in abundance of a wild pollinator mediates pollen deposition rates to blueberry

open access: yesBasic and Applied Ecology, 2023
Intra-seasonal variation in abiotic and biotic conditions can have profound consequences for pollinator community compositions and foraging movement, with flow-on effects upon pollination services.

Machine Learning and Geospatial Modeling of Climate Change Impacts on Ethiopian Honeybees for Conservation and Resilient Agriculture

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
The current study used machine learning and geospatial analysis to predict how climate change will loosen and fragment suitable habitats for Ethiopian honeybees. Main factors like agro‐ecological zones and dry‐season precipitation were found to be critical for bee survival.

Microbial Pressure and Social Immunity: Bumble Bees Increase Brood Hygiene After Exposure to a Bacillus thuringiensis‐Based Biopesticide

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
In social insect colonies, diseased or dead brood is identified and removed by workers to prevent the infection of the whole colony. Here, bumble bee larvae exposed to a bacterium (Bacillus thuringiensis ssp. aizawai (strain: ABTS‐1857)) based biopesticide were removed more frequently than wounded or untreated control larvae. This shows that bumble bee
