Integrating Population Genomics and Historical Occurrence Data to Assess the Impact of Land‐Use Changes on Centris Oil Bees in the Brazilian Cerrado

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Habitat loss and fragmentation (HLF) are among the major drivers of bee decline, yet closely related species often show contrasting responses depending on their ecological and demographic traits. The Brazilian Cerrado biodiversity hotspot experiences among the world's highest rates of HLF.

Combining Distribution Models of Plants and Their Mutualists to Map Gaps in the Knowledge of Ecological Interactions

Diversity and Distributions, Volume 31, Issue 10, October 2025.
ABSTRACT Aim The distribution of species relying on mutualistic partners for reproduction can be constrained by their partners' distribution. Nonetheless, biotic interactions are often overlooked when estimating the distributions of species (e.g., pollinators of a given plant and the proportion of them with their distribution modelled). In the Tropics,

Por que machos de abelhas Eulaema nigrita (Hymenoptera: Euglossini) coletam o mesófilo de folhas de Guarea guidonia (Meliaceae)? [PDF]

, 2006
Males of Euglossini bees harvest aromatic compounds to synthesize sexual pheromones. This work describes the euglossine Eulaema nigrita harvesting mesophyll from leaves of Guarea guidonia for the first time.

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.

Pharmacophagy in insects: Ecological and evolutionary perspectives on the non‐nutritional use of plant specialized metabolites

Entomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 661-673, July 2025.
Insects interact with plants not only for nutrition but also to actively seek plant specialized metabolites (PSMs) for chemical defense, reproduction, and self‐medication—a behavior known as pharmacophagy. This review examines how insects across diverse orders acquire PSMs from both food and non‐food plants for non‐nutritional benefits.

Landscape influence on pollinator population genetic connectivity

Insect 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 ...

Orchid bee (Hymenoptera: Apidae) community from a gallery forest in the Brazilian Cerrado

Revista de Biología Tropical, 2012
The orchid bees are a very important group of pollinators distributed in the Neotropics. Although a lot of studies concerning male euglossine bees have been done in this region, few works have so far been carried out in the Cerrado biome. This manuscript

Interactions between carpenter bees and orchid bees (Hymenoptera: Apidae) in flowers of Bertholletia excelsa Bonpl. (Lecythidaceae) Interações entre abelhas carpinteiras e abelhas das orquídeas (Hymenoptera: Apidae) em flores de Bertholletia excelsa Bonpl. (Lecythidaceae)

Acta Amazonica, 2012
Competition between two species of bees for the same type of floral resource may generate antagonistic behavior between them, especially in cultivated areas where food resources are limited, seasonally and locally.
