Are isomeric alkenes used in species recognition among neo-tropical stingless bees (Melipona spp) [PDF]

, 2017
The majority of our understanding of the role of cuticular hydrocarbons (CHC) in recognition is based largely on temperate ant species and honey bees. The stingless bees remain relatively poorly studied, despite being the largest group of eusocial bees ...

The Constructive Neutral Evolution of Behaviour

Ecology and Evolution, Volume 15, Issue 7, July 2025.
We explain how constructive neutral evolution (CNE) can lead to the evolution of nonfunctional behavioural complexity, highlighting a mechanism that is unknown to behavioural ecologists despite being frequently considered by molecular biologists. We summarise indirect evidence that suggests behavioural CNE has occurred and outline how the hypothesis ...

Multi‐Omic Analysis Reveals Population Differentiation and Signatures of Social Evolution in Tetragonula Stingless Bees

Molecular Ecology, Volume 34, Issue 13, July 2025.
ABSTRACT Stingless bees in the genus Tetragonula are social insects with a fully sterile worker caste, and are therefore well‐placed to provide insights into the genomic changes associated with ‘superorganismal’ life histories. Here we assemble the genome of Tetragonula carbonaria and characterise the population structure and divergence of both T ...

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

Austral 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.

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

Biotropica, 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.
