Managed honey bees (Apis mellifera) play a vital role in pollinating cultivated crops worldwide. Honey bee colony declines reported in the past two decades have been associated with stressors such as pests and diseases, pesticide exposure, and poor nutrition. In the wake of these colony declines, beekeepers have strived to...
Using the honey bee (Apis mellifera L.) this thesis shows that entomological information and material can be retrieved using current historical archaeological methods. Historical archaeology has the ability to uncover connections between arenas as varied, and seemingly isolated, as the honey bee, the environment, and human cultures. By focusing on...
Pollination is an essential ecosystem service that sustains functioning ecosystems and aids in food production. In response to recent, widespread declines of managed and native bee populations, many land managers have shown interest in developing conservation and restoration plans for enhancing native bee habitat. However, there is a lack of...
Bumble bees (Hymenoptera: Apidae) are important native pollinators in wild and agricultural systems, and are one of the few groups of native bees commercially bred for use in the pollination of a range of crops. In recent years, declines in bumble bees have been reported globally. One factor implicated in...
Animal pollination is critical to plant reproduction in agricultural and wildland ecosystems. Much of the production of seeds and fruits in natural areas, which underlie many food webs, depends on pollination services by insects. The taxon responsible for delivering the bulk of these services in most temperate systems is bees....
Native bees play an important role as pollinators of natural vegetation and agricultural
crops. Yet many pollinators, including some native bees, are declining in numbers.
