Crop pollination from native bees at risk from agricultural intensification
TLDR
It was found that diversity was essential for sustaining the service, because of year-to-year variation in community composition, and conservation and restoration of bee habitat are potentially viable economic alternatives for reducing dependence on managed honey bees. Expand
The area requirements of an ecosystem service: crop pollination by native bee communities in California
TLDR
This work investigated how crop pollination services provided by native, unmanaged, bee communities varied on organic and conventional farms situated along a gradient of isolation from natural habitat, allowing prediction of the area needed to produce a given level of pollination Services by wild bees within this landscape. Expand
Delivery of crop pollination services is an insufficient argument for wild pollinator conservation
TLDR
It is shown that, while the contribution of wild bees to crop production is significant, service delivery is restricted to a limited subset of all known bee species, suggesting that cost-effective management strategies to promote crop pollination should target a different set of species than management Strategies to promote threatened bees. Expand
Wild pollination services to California almond rely on semi‐natural habitat
TLDR
Although honeybees are the main and most important pollinating insects for many plants, wild pollinators may be necessary to ensure high fruit set and the restoration of high quality habitat strips along the edges of crop fields in highly intensified agricultural landscapes should be encouraged to conserve pollinators and to determine whether benefits for agriculture can be realized.

Ecological Patterns of Bees and Their Host Ornamental Flowers in Two Northern California Cities
TLDR
Overall, many bee species seem pre-adapted to use extant urban resources for forage, reproduction and survival in residential areas of these two California cities. Expand
STRUCTURAL, BEHAVIORAL, AND PHYSIOLOGICAL ADAPTATIONS OF BEES (APOIDEA) FOR COLLECTING POLLEN'
Bees, like their wasp relatives, forage for and transport food to a nest as provisions for their offspring. Unlike female Sphecoidea which transport arthropods one at a time as prey, bees transportExpand
Ecology of Urban Bees: A Review of Current Knowledge and Directions for Future Study
Urban bee ecology is an emerging field that holds promise for advancing knowledge of bee community dynamics and promoting bee conservation. Published studies of bee communities in urban and suburbanExpand
The collection of pollen by bees
TLDR
The various structural and behavioral adaptations of female bees for acquiring and transporting pollen are the basis of this review. Expand
