Enhancing Lasioglossum (Homalictus) dotatum (Hymenoptera: Halictidae) habitats: The role of rock gravel in bare soil landscapes

open access: yesAustral Entomology, Volume 64, Issue 2, May 2025.
Abstract Native bee populations are generally in decline, and although their conservation needs are recognised, habitat requirements for the majority of species remain unknown. Many bee species construct nests underground, including the native Australian bee Lasioglossum (Homalictus) dotatum.

Chemical profile and antioxidant, anti-inflammatory, antimutagenic and antimicrobial activities of geopropolis from the stingless bee Melipona orbignyi [PDF]

open access: yes, 2017
Licensee MDPI, Basel, Switzerland. Geopropolis is a resin mixed with mud, produced only by stingless bees. Despite being popularly known for its medicinal properties, few scientific studies have proven its biological activities.

Phenotypic, Floristic, and Anthropogenic Drivers of the Pollen Niche of Amazonian Stingless Bees

open access: yesBiotropica, Volume 57, Issue 3, May 2025.
The pollen diversity and composition collected by Amazonian stingless bees depend on their body mass, tree composition, and urbanization. Further, bees have been collecting fewer pollen types since the 1970s. ABSTRACT Stingless bees (Apidae: Meliponini) are major pollinators in the tropics, supporting key ecosystem services.

The deposition of anal excretions by Melipona favosa foragers (Apidae: Meliponinae): behavioural observations concerning the location of food sources [PDF]

open access: yes, 2000
Melipona favosa consistently deposited anal excretions while foraging. Anal depositions were released more frequently and by more bees on artificial food sources at a greater distance from the nest.

Landscape influence on pollinator population genetic connectivity

open access: yesInsect Conservation and Diversity, Volume 18, Issue 3, Page 285-302, May 2025.
We analysed 113 studies from 59 countries, covering 96 bee and 21 hoverfly species, to review the evidence of environmental and landscape effects on the population genetic connectivity in pollinators. Environmental conditions (precipitation and temperature), topography (elevation and sea), and land use (agriculture, deforestation, urbanisation) were ...

Comparative molecular cytogenetics in Melipona Illiger species (Hymenoptera, Apidae)

open access: yesSociobiology, 2018
Cytogenetic studies in Melipona are scarce with only 24 species analyzed cytogenetically. Of these, six species had the rDNA sites physically mapped and characterized by Fluorescent in situ Hybridization (fish).
