Network Assemblages of Elevational Niche-Associated Diversity in Fijian Native Bees. [PDF]

Ecol Evol
Using network analyses, this paper demonstrates the aggregated distribution of Fijian Lasioglossum (Homalictus) bees in elevational niches. Combining the nestedness explored in this study with previous research, we highlight the conservatism in these bees and discuss their vulnerability as a result.

First record of Hylaeus (Gnathoprosopis) euxanthus (Hymenoptera: Colletidae) in Chile [PDF]

, 2019
A 2009 field survey at Cerro San Cristobal, Santiago, Chile, revealed the presence of Hylaeus (Gnathoprosopis) euxanthus (Cockerell, 1910). Since then, numerous individuals have been observed visiting several plant species around Santiago and Valparaíso.

Contrasting patterns of turnover between plants, pollinators and their interactions [PDF]

, 2014
Aim: Biogeographers typically assess patterns of diversity across landscapes. As interacting groups often exhibit contrasting trends, this leads to variation in the structure of interaction networks and thereby influences ecosystem processes. Here we aim

Canopy specialist Hylaeus bees highlight sampling biases and resolve Michener’s mystery

Frontiers in Ecology and Evolution
Large parts of the Pacific were thought to host low bee diversity. In Fiji alone, our recent estimates of native bee diversity have rapidly increased by a factor of five (from 4 to >22).
