For the past six years in which overwintering mortality of honey bee colonies has been surveyed in the USA, estimates of colony loss have
fluctuated around one-third of the national population. Here we report on the losses for the 2012-2013 seasons. We collected data from 6,482
US beekeepers (6,114 backyard,...
The importance of pollinators in native and managed landscapes is well known, and recent interest is directed towards investigating the role of native bees as providers of pollination ecosystem services. Uncertainty about bee populations at global and local scales has prompted research and general interest in conservation of bee diversity....
Due to a growing body of literature documenting declines in pollinator populations, there has been increased public interest in pollinator conservation. In urban and suburban landscapes, many gardeners and urban land managers are interested in gardening for pollinators, particularly bees. Simultaneously, many homeowners and municipalities are interested in other aspects...
Larval mortality of leafcutting bee, Megachile pacifica (Panzer)
(= rotundata (F.)), is high, usually exceeding 50%. Parasites and
predators are not a limiting factor in the survival of the progeny.
The disease chalk brood has been an important mortality factor since
1974. Inadequate food supply, pollen and nectar, may affect...
Dual use pasture systems, sometimes referred to as dual purpose pasture systems, take advantage of the land being used to maximize multiple outputs from a single area. Developing a system to support both production of grazing livestock as well as pollinator health is of increasing importance in pasture-based farming systems....

These are research reports only, not management recommendations.
This work combines both applied and basic research regarding previously undescribed relationships between two ecologically and economically important insect groups in coniferous forests, bark beetles (Coleoptera: Curculionidae, Scolytinae) and wild bee (Hymenoptera: Apiformes) communities in Western North America. Across the continent, native bark beetle outbreaks are key drivers of structural...
Honey wine, also known as mead, is one of the oldest alcoholic beverages known to man. Made primarily from honey, water, and yeast, this beverage has recently been experiencing a resurgence in popularity. It is imperative that commercial producers focus on consistently creating quality products to differentiate themselves from competitors...
Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that...
