Patterns of widespread decline in North American bumble bees
TLDR
It is shown that the relative abundances of four species have declined by up to 96% and that their surveyed geographic ranges have contracted by 23–87%, some within the last 20 y, although cause and effect remain uncertain.

Effect of Human Disturbance on Bee Communities in a Forested Ecosystem
TLDR
The results suggest that at least in this system, moderate anthropogenic land use may be compatible with the conservation of many, but not all, bee species.

Sampling Bee Communities (Hymenoptera: Apiformes) in a Desert Landscape: Are Pan Traps Sufficient?
TLDR
Though pan trapping constitutes a standardized method that avoids collector bias, it may not be unbiased; capture rates were lowest when flowering plant richness was greatest, and net collecting should be used in addition to pan traps if comprehensive inventories are desired.

Substrates and Materials Used for Nesting by North American Osmia Bees (Hymenoptera: Apiformes: Megachilidae)
TLDR
Nesting substrates and construction materials are compared for 65 of North America’s 139 described native species of Osmia bees to indicate the range of nesting habits and materials of European species are largely comparable, although records indicate that far more European species may nest in empty snail shells.

Might Flowers of Invasive Plants Increase Native Bee Carrying Capacity? Intimations From Capitol Reef National Park, Utah
TLDR
It is argued that invasives with entomophilous flowers are unlikely to either facilitate the reproduction of uncommon native plants or consistently compete with them for pollinators, and are likely, over time, to selectively increase the carrying capacity and population size of native bees.

Pyrodiversity begets plant–pollinator community diversity
TLDR
It is found that pyrodiversity is positively related to the richness of the pollinators, flowering plants, and plant-pollinator interactions, and a diversity of fire characteristics contributes to the spatial heterogeneity (β-diversity) of plant and pollinator communities.

Global invasion by Anthidium manicatum (Linnaeus) (Hymenoptera: Megachilidae): assessing potential distribution in North America and beyond
TLDR
The wool carder bee, Anthidium manicatum, is the most widely distributed unmanaged bee in the world and its naturalization in North America, possibly through punctuated dispersal, the probability of suitable habitats across the globe and the synanthropy exhibited by this invasive species are discussed.
