Mountain colonization precedes shifts away from bee pollination in Melastomataceae
New Phytologist, Volume 247, Issue 3, Page 1474-1492, August 2025.Summary Shifts among different groups of pollinators are central in the evolution of flowering plants, yet mechanisms underlying pollinator shifts remain unclear. Environment‐induced reduction in pollinator availability and hence efficiency may destabilize ancestral plant–pollinator interactions and trigger shifts to new, more efficient pollinators ...

MicroRNAs Associated with Caste Determination and Differentiation in a Primitively Eusocial Insect [PDF]
, 2017 In eusocial Hymenoptera (ants, bees and wasps), queen and worker adult castes typically arise via environmental influences. A fundamental challenge is to understand how a single genome can thereby produce alternative phenotypes. A powerful approach is to

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.

Kinematics of hovering hummingbird flight along simulated and natural elevational gradients [PDF]
, 2003 Hovering flight is one of the most energetically demanding forms of animal locomotion. Despite the cost, hummingbirds regularly hover at high elevations, where flight is doubly challenging because of reduced air density and oxygen availability.

La arquitectura de nidos de Euglossa (Euglossa) hemichlora (Hymenoptera: Apidae: Euglossini)
Revista Colombiana de Entomología, 2009 La información sobre la biología de nidificación de las abejas de las orquídeas es escasa debido a la gran dificultad para encontrar sus nidos. Se presentan observaciones y comentarios sobre la arquitectura de los nidos de Euglossa hemichlora obtenidos a partir de nidos trampa a la vez que se presentan datos de la biología de nidificación de esta ...

Trapline foraging by bumble bees: VI. Behavioral alterations under speed–accuracy trade-offs [PDF]
, 2013 Trapline foraging (repeated sequential visits to a series of feeding locations) has often been observed in animals collecting floral resources. Past experiments have shown that bumble bees cannot always develop accurate (i.e., repeatable) traplines to a ...
