Comparative 1H NMR Metabolomics Between Scandinavian Propolis and Australian Propolis: The Quest to Identify Radical Scavenging Compounds

Magnetic Resonance in Chemistry, Volume 64, Issue 4, Page 438-450, April 2026.
Propolis from Scandinavia and Australia was chemically characterized using 1H NMR spectroscopy and multivariate modeling. Recursive partial least squares revealed spectral features associated with radical scavenging activity, and STOCSY enabled identification of the key phenolic compounds underlying these bioactive features. ABSTRACT Propolis from Apis

Floral trait similarity at the community‐level increases reproductive success suggesting facilitation through pollinator sharing

Oikos, Volume 2026, Issue 4, April 2026.
The ability of plants to attract pollinators is context‐dependent, influenced by floral traits, abundance, and resources from the plant community. Indirect interactions through shared pollinators, from competition to facilitation, may lead to varied reproductive outputs in plants, and the mechanisms behind these interactions remain to be fully ...

Hygienic behaviour in Brazilian stingless bees

Biology Open, 2016
ABSTRACT Social insects have many defence mechanisms against pests and pathogens. One of these is hygienic behaviour, which has been studied in detail in the honey bee, Apis mellifera. Hygienic honey bee workers remove dead and diseased larvae and pupae from sealed brood cells, thereby reducing disease transfer within the colony ...

Indigenous Knowledge, Habitat, and Nest Characterization of Stingless Bee (Meliponula beccarii) in West Arsi Zone of Oromia, Ethiopia

Psyche: A Journal of Entomology
Stingless bees are eusocial insects that play vital roles as pollinators of many flowering plants and high value products. However, information on their nesting habitats and nest characteristics is scarce in West Arsi Zone of Oromia, Ethiopia. This study

Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

TAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

A Scientific Note on a Stingless Bee Hive Model for Ecological and Behavioral Studies and for Environmental Education

Sociobiology, 2019
Stingless bees (Apidae; Meliponini) occupy a great diversity of habitats in tropical and subtropical regions. They are eusocial and live in sessile colonies. Most meliponini species build nests in pre-existing cavities, such as tree hollows and stingless

Beeswax: Food and beyond

Food Biomacromolecules, Volume 3, Issue 1, Page 93-112, March 2026.
Abstract Honeybees (Apis mellifera L.) are an important class of insects that are the most beneficial in terms of economy. Beeswax is the second most important bee products after honey. Its commercial importance is due to its antimicrobial, antioxidant, anti‐inflammatory and antiseptic as well as regenerative properties.

Distance and habitat drive fine scale stingless bee (Hymenoptera: Apidae) community turnover across naturally heterogeneous forests in the western Amazon

Sociobiology, 2014
High tree species richness in the western Amazon has been attributed to heterogeneous soils, which harbor edaphic specialist trees. While rapid transitions in tree communities are well documented across these variable soils few studies have investigated ...

The Role of Useful Microorganisms to Stingless Bees and Stingless Beekeeping [PDF]

, 2012
Bacteria, molds, and yeasts associated with bees have been studied for a long period. Although they seem to play an important role for bee nutrition and protection against harmful microorganisms, few studies have focused on their function and this subject is still very controversial.

Visual physiology of Australian stingless bees

Journal of Comparative Physiology A
Abstract Stingless bees engage in a range of visually guided behaviours that require relatively high spatial resolution and contrast sensitivity. Although the eyes of honeybees, bumblebees, carpenter bees, and sweat bees have been studied extensively, there is limited knowledge of stingless bees.
