Gene Flow Across Large Distances in the Cavity-Nesting Wasp <i>Deuteragenia subintermedia</i> in a Central European Forest. [PDF]

Ecol Evol
Retention forestry is widely considered a promising approach to conserve forest biodiversity, and beneficial effects of more heterogeneous forest structure have been shown for several taxa. However, it is often unclear if the approaches taken locally can provide connectivity for specimens over the landscape or if they lead to “biodiversity islands ...

Molecular bases of insect odorant receptor function: specificity and evolution. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

Glossuropoda, novo subgênero de Euglossa, e duas espécies novas da Amazônia, do mesmo subgênero (Apidae - Hymenoptera) Glossuropoda, new subgenus of Euglossa, and two new species of Amazônia belonging the same subgenus (Apidae - Hymenoptera)

Memorias do Instituto Oswaldo Cruz, 1989
A new subgenus Glossuropoda is proposed for Euglossa intersecta Latreille, 1837, as the type species. It is distinguished from Glossura by having a very peculiar configuration of the mid basitarsus of the male and lack of the median spur. Two new species

Biología de anidación de Euglossa dodsoni Moure (Hymenoptera: Euglossinae) en Panamá

, 2020
The orchid bee genus Euglossa contains more than 100 species distributed throughout the Neotropics from Paraguay to Mexico (Michener, 2000). Most species nest in protected cavities such as in logs, trunks, small cavities between rocks, and man-made ...

Raising the sugar content--orchid bees overcome the constraints of suction feeding through manipulation of nectar and pollen provisions. [PDF]

PLoS ONE, 2014
Unlike most other bees, the long-tongued orchid bees ingest nectar using suction feeding. Although long tongues allow exploitation of flowers with deep spurs, the energy intake rate is optimal at 10-20% lower nectar sugar concentrations compared to that ...

Large carpenter bees show high dispersal in a tropical semi-arid region susceptible to desertification. [PDF]

Ecol Evol
This study examines the genetic status of native carpenter bees in a Brazilian region vulnerable to desertification. Employing a population genomic approach, we found low genetic diversity with high homogeneity across populations, even over distances exceeding 300 km.
