Does temporal variability in floral resources at the landscape scale impact wild bee diversity and watermelon pollination?
Context: The stability of flower resources in agricultural landscapes affects wild bee communities. Mass flowering crops provide …
Mechanisms and Consequences of Plant–Pollinator–Pathogen Interactions
Infectious disease is a major driver of biodiversity loss, but how disease threatens pollinator communities remains poorly understood. …
Wildflower plantings and honeybee competition impact nutritional quality of wild bee diets
Wildflower habitats planted along field borders are a widely promoted strategy for supporting bees in agricultural landscapes. However, …
Evidence of exploitative competition between honey bees and native bees in two California landscapes
- Human-mediated species introductions provide real-time experiments in how communities respond to interspecific competition. For …
Honey bee introductions displace native bees and decrease pollination of a native wildflower
Introduced species can have cascading effects on ecological communities, but indirect effects of species introductions are rarely the …
A meta-analysis of single-visit pollination effectiveness comparing honeybees and other floral visitors
In our analysis of 168 pollination effectiveness studies, we found that honey bees were less effective than the average bee and rarely …
Impact of “non-lethal” tarsal clipping on bumble bees (Bombus vosnesenskii) may depend on queen stage and worker size
Recent bumble bee declines have prompted the development of novel population monitoring tools, including the use of putatively …
The importance of competition between insect pollinators in the Anthropocene
Resource competition likely plays an important role in some insect pollinator declines and in shaping effects of environmental change …
A lever action hypothesis for pendulous hummingbird flowers: experimental evidence from a columbine
Background and Aims - Pendulous flowers (due to a flexible pedicel) are a common, convergent trait of hummingbird-pollinated flowers. …
Fantastic bees and where to find them: locating the cryptic overwintering queens of a western bumble bee
Bumble bees are among the best-studied bee groups worldwide, yet surprisingly we know almost nothing about their overwintering habitats …
Pollinator effectiveness in a composite: a specialist bee pollinates more florets but does not move pollen farther than other visitors
Premise - Variation in pollinator effectiveness may contribute to pollen limitation in fragmented plant populations. In plants with …
