Sampling Bee Communities (Hymenoptera: Apiformes) in a Desert Landscape: Are Pan Traps Sufficient?
Abstract Pan traps (colored plastic bowls) are frequently used as an efficient standardized method of sampling bee faunas. We explored the utility of pan traps in three colors compared to net… Expand
Substrates and Materials Used for Nesting by North American Osmia Bees (Hymenoptera: Apiformes: Megachilidae)
Abstract Nesting substrates and construction materials are compared for 65 of North America’s 139 described native species of Osmia bees. Most accounts report Osmia bees nesting in preexisting… Expand
Phylogeny of the bee family Megachilidae (Hymenoptera: Apoidea) based on adult morphology
Phylogenetic relationships within the bee family Megachilidae are poorly understood. The monophyly of the subfamily Fideliinae is questionable, the relationships among the tribes and subtribes in the… Expand
Bumble bees influence berry size in commercial Vaccinium spp. cultivation in British Columbia
We studied the abundance, diversity, and dispersion patterns of managed and wild bee (Hymenoptera: Apoidea) populations in commercial highbush blueberry and cranberry (Ericaceae: Vaccinium corymbosum… Expand
Pollinator nesting guilds respond differently to urban habitat fragmentation in an oak‐savannah ecosystem
Abstract. 1. Habitat fragmentation is thought to threaten biodiversity, but the response of pollinators to fragmentation is still poorly understood, and research seldom includes pollinator nesting… Expand
Variation between bee communities on a sand dune complex in the Great Basin Desert, North America: implications for sand dune conservation.
Abstract Sand dunes across the Mojave and Great Basin Deserts house rich bee communities. The pollination services these bees provide can be vital in maintaining the diverse, and often endemic, dune… Expand
Bee Associates of Flowering Astragalus and Onobrychis Genebank Accessions at a Snake River Site in Eastern Washington
Abstract A 3 yr survey of the bee associates of flowering accessions of Astragalus and Onobrychis species was conducted in open-pollinated field nurseries at Central Ferry, Washington to gain insight… Expand
Pollinators Complicate Conservation of an Endemic Plant: Physaria obcordata (Cruciferae) in the Piceance Basin, Colorado
DEDICATION: To the unnamed road grader operator, resident of Rangeley CO, who on May 13, 1992, idled his machine atop Calamity Ridge and jumped down to admonish us, as we collected insects from P.… Expand
Documenting Persistence of Most Eastern North American Bee Species (Hymenoptera: Apoidea: Anthophila) to 1990–2009
Abstract The status of wild bees, the major group of pollinators in most biomes, has gained recognition as an important ecological and economic issue. Insufficient baseline data and taxonomic… Expand
