Wild bee pollinators provide the majority of crop visitation across land‐use gradients in New Jersey and Pennsylvania, USA
Summary 1 Concern about a global decline in wild pollinators has increased interest in how pollinators are affected by human land use, and how this, in turn, affects crop pollination. 2 WeExpand

Evolution and phylogenetic utility of alignment gaps within intron sequences of three nuclear genes in bumble bees (Bombus).
To test whether gaps resulting from sequence alignment contain phylogenetic signal concordant with those of base substitutions, we analyzed the occurrence of indel mutations upon a well-resolved,Expand

NOTES ON THE NATIVE BEE POLLINATORS IN NEW YORK APPLE ORCHARDS
Abstract We surveyed apple orchards in the Finger Lakes region of New York State. Pollinator guilds included many honey bees and native bee species known to be effective pollinators of apples. Of theExpand

Phylogenetic utility of the major opsin in bees (Hymenoptera: Apoidea): a reassessment.
Major opsin (LW Rh) DNA sequence has been reported to provide useful data for resolving phylogenetic relationships among tribes of corbiculate bees based on analyses of 502 bp of coding sequence.Expand

Phylogenetic analysis of the corbiculate bee tribes based on 12 nuclear protein-coding genes (Hymenoptera: Apoidea: Apidae)
The corbiculate bees comprise four tribes, the advanced eusocial Apini and Meliponini, the primitively eusocial Bombini, and the solitary or communal Euglossini. Recovering a robust phylogeny for theExpand
