Hair‐based minimally invasive barcoding of bumblebees

Insect Conservation and Diversity, Volume 18, Issue 2, Page 127-139, March 2025.
We investigated a minimally invasive sampling method for barcoding bumblebees based on hair. The method was tested with commercially reared specimens, older collection material and field‐caught animals. Barcoding success depends on sample origin—commercially reared and frozen collection samples yielded the best results. Wild‐caught animals' species (88%

Revisiting ecological specialization: the case of plant–frugivore interactions

Oikos, Volume 2025, Issue 3, March 2025.
Understanding the extent to which organisms exhibit specialization when interacting with or relying on distinct aspects of their biotic and abiotic environment is a central tenet in ecology and evolution. Despite the relevance of the concept and theoretical advances, specialization has and continues to be ambiguously defined. Here we review the uses of

The orchid-bee fauna (Hymenoptera: Apidae) of a forest remnant in the southern portion of the Brazilian Amazon

Brazilian Journal of Biology
The orchid-bee fauna of the region of Porto Velho, in the state of Rondônia, Brazil, close to the southernmost limits of the Amazon Basin, was surveyed for the first time using five different scents as baits to attract orchid-bee males.

Aerial litter mimicry: A novel form of floral deception mediated by a monoterpene synthase

Journal of Ecology, Volume 113, Issue 2, Page 302-321, February 2025.
We report the first pollination system in which a flower imitates aerial litter, which refers to the arboreal plant litter in a forest. Our findings demonstrated that Meiogyne heteropetala flower fooled the aerial litter specialist Loberus sharpi by mimicking aerial litter in size, colour and odour.

Is the “Centro de Endemismo Pernambuco” a biodiversity hotspot for orchid bees?

Brazilian Journal of Biology
The orchid-bee faunas (Hymenoptera: Apidae: Euglossina) of the three largest forest remnants in the “Centro de Endemismo Pernambuco”, northeastern Brazil, namely Estação Ecológica de Murici (ESEC Murici), RPPN Frei Caneca, and a forest preserve belonging

Temporal variation in the abundance of Orchid Bees (Hymenoptera: Apidae) in a Neotropical Hygrophilous Forest

Sociobiology, 2014
Although bees are important pollinators in several ecosystems around the world, studies on bee diversity in hygrophilous forests are scarce. This type of vegetation is restricted to permanently wet soils and, therefore, has particular floristic ...

Non‐floral scent sources of orchid bees: Observations and significance

Biotropica, Volume 57, Issue 1, January 2025.
We observed male euglossines collecting scent at 21 different non‐floral sources in Central and South America, strengthening the view that these sources play a central role in euglossine perfume biology. A Protium tree provided over 50% of the perfumes for Eufriesea corusca and was repeatedly revisited.

Orchid bees (Hymenoptera, Apidae, Euglossini) are seasonal in Seasonal Semideciduous Forest fragments, southern Brazil

Papéis Avulsos de Zoologia, 2019
Seasonal fluctuations in the abundance of orchid bees have already been reported. The variations in population dynamics may be expected to occur in more predictable and pronounced manners in environments with a clear distinction between rainy and dry ...

Prezygotic barriers effectively limit hybridization in a rapid evolutionary radiation

New Phytologist, Volume 244, Issue 6, Page 2548-2560, December 2024.
Summary Hybridization is increasingly recognized as an important evolutionary process across the tree of life. In many clades, phylogenomic approaches have permitted unparalleled insight into the extent and frequency of hybridization. However, we continue to lack a deep understanding of the factors that limit and shape patterns of hybridization ...

Different Physiognomies and the Structure of Euglossini bee (Hymenoptera: Apidae) Communities

Sociobiology, 2018
Our aim was to evaluate the occurrence of orchid bees in remnants of the Atlantic Forest. We sampled specimens from five regions of Southeast Brazil, covering three different physiognomies of the Atlantic Forest (mixed Araucaria forests with high ...
