Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges

Insect Conservation and Diversity, EarlyView.
Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...

Gynandromorphy in Eulaema atleticana Nemésio (Apidae, Euglossini)

EntomoBrasilis, 2012
A gynandromorph specimen of Eulaema atleticana Nemésio, the first registered in Eulaema, is described. The E. atleticana gynandromorph was captured using an eucalyptol scent trap, in the Mata do Buraquinho Reserve, an Atlantic Forest fragment. The study site has 550 ha and is located in the urban area of the Municipality of João Pessoa, State of ...

Would Eulaema nigrita (Hym.: Apidae: Euglossini) be a reliable organism as a bioindicator of degraded environments?

CONTRIBUCIONES A LAS CIENCIAS SOCIALES, 2023
Euglossini bees are recognized as orchid bees, they have a great importance as neotropical pollinators. Males are collectors of aromatic substances in flowers of several species of plants, but mainly of Orchidaceae. This tribe is composed of five genera, with the specie Eulaema nigrita Lepeletier considered in the group as a bioindicator species of ...

Urban Landscape Influence Orchid Bee Diversity in a Tropical Megacity

Journal of Applied Entomology, EarlyView.
ABSTRACT The increasing urbanization has affected pollinator communities, such as Euglossini bees, which play a crucial role in maintaining biodiversity through the pollination of numerous plants. However, the impact of different levels of urbanization on the diversity of these bees is still not fully understood, especially in large tropical urban ...

Fire modulates the structural drivers and functioning of individual‐based plant‐pollinator networks

Journal of Ecology, Volume 114, Issue 5, May 2026.
Ecological drivers that shape (positively or negatively) the plant‐pollinator network and determine plant fitness, both before and after a fire. Abstract Fire is a natural phenomenon that shapes ecosystems, but climate change and human activities have increased its frequency and magnitude, disrupting essential ecosystem services like pollination ...

Seasonal dynamics in terrestrial insect communities after the impact of the Brumadinho tailings dam disaster

Insect Conservation and Diversity, Volume 19, Issue 3, Page 634-646, May 2026.
Despite severe habitat loss, insect species richness, seasonal fluctuations in richness and temporal β‐diversity did not differ significantly among forests adjacent to the mudflow and reference sites. We found higher wet‐season species richness for ants, bees, butterflies and dung beetles, while termites showed no seasonal change; β‐diversity was ...
