Are orchid bees at risk? First comparative survey suggests declining populations of forest-dependent species

Brazilian Journal of Biology
The two largest Atlantic Forest remnants in the state of Espírito Santo, eastern Brazil, namely ‘Reserva Biológica de Sooretama’ (REBIO Sooretama) and ‘Reserva Natural Vale’ (RNV), were surveyed for their orchid-bee faunas.

Cultura caballista

American Ethnologist, Volume 53, Issue 3, Page 296-309, August 2026.
Abstract The world of Colombian gaited horses, or cultura caballista (horse‐riding culture), is often linked with uribismo, the right‐wing identity associated with former president Álvaro Uribe Vélez. Ethnographic fieldwork in conflict‐torn Antioquia reveals how horse‐human practices of training, breeding, and competition cultivate orientations toward ...

Evidence of introduced honeybees (Apis mellifera) as pollen wasters in orchid pollination

Scientific Reports
Biological invasions threaten global biodiversity, altering landscapes, ecosystems, and mutualistic relationships like pollination. Orchids are one of the most threatened plant families, yet the impact of invasive bees on their reproduction remains ...

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 ...

Orchid genome evolution and trait innovation

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2577-2607, August 2026.
Orchids became one of the world's most diverse plant groups through genome‐driven innovations, unique relationships with fungi and pollinators, and remarkable adaptability. This review explains the origins of orchids and the evolution of their distinctive life forms, flowers, and ecological strategies and highlights promising directions for future ...

Orchid bees as bio-indicators for organic coffee farms in Costa Rica: Does farm size affect their abundance?

Revista de Biología Tropical, 2006
The potential of Euglossini bees, especially Euglossa, as biological indicators of organic vs non-organic coffee farms was studied in Atenas and San Isidro, Alajuela, Costa Rica using 1.8-cineole as lure.

Light and Pollination Limitation Alter Patterns of Fitness and Phenotypic Selection in Sagittaria trifolia L.: Insights From Sequential Inflorescences

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We examined how light limitation and reduced pollinator access influence female fitness and phenotypic selection in Sagittaria trifolia across sequential inflorescences. Open‐grown plants produced the most inflorescences, flowers, and seeds, whereas mesh‐enclosed plants compensated for low early fruit set through later reproductive adjustment and ...

Form and Law ‐ Rupert Riedl's Significance for Morphology

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 5, Page 383-389, July 2026.
ABSTRACT Rupert Riedl showed in his “Order in Living Organisms” that morphology can produce law statements and is, therefore, a proper, that is, nomothetic, science. Furthermore, he coined useful terms (interphene and metaphene) and concepts (burden, cadre and minimal homology).

A missing piece in the puzzle: the presence of Euglossa viridissima in the Baja California Peninsula (Hymenoptera, Apidae)

ZooKeys, 2018
Orchid bees are a conspicuous component of the neotropical bee fauna, with a few species reaching the northernmost natural distribution for the group in northwestern continental Mexico.

Tropical Bee Assemblage Diversity Decreases With Elevation While Body Size Increases

Biotropica, Volume 58, Issue 4, July 2026.
Photos of bee specimens collected in the Colombian Andes across a nearly 3000 m elevational cline. They are arranged to illustrate both the decline in richness with elevation and the increase in community average body size with elevation. ABSTRACT Elevation gradients are powerful drivers of changes in species composition, richness, and functional ...
