Soil sand content is a driving force in structuring bee communities
We conducted a carefully designed observational study across three soil sand content categories using Dalea purpurea that attracts a wide range of bee species and grows in different soil types. Soil sand content, not floral resource availability, affected patterns of bee distribution, and contrary to expectations, sandier sites did not host the highest

Estimating wild bee population size with validated distance sampling
Distance Sampling is a promising method to estimate population size but has never been validated on insects. We validated it on a honey bee population of known size. We applied Distance Sampling to three insular pollinators and found that estimates are consistent across days, match species phenology and reflect the expected influence of weather ...

Year‐round pollinator visitation of ornamental plants in Mediterranean urban parks
Pollinators visiting ornamental plants in urban parks remained diverse throughout the year. They were represented by wild bees (42%), honeybees (37%), flies (18%), butterflies (2%) and beetles (1%). Both native and non‐native plants attracted pollinators.

Genetic Basis of UV Bullseye Size Variations in Turnip Rape (Brassica rapa subsp. oleifera)
ABSTRACT Floral ultraviolet (UV) patterns are visible to bee pollinators and can affect crop yields by impacting pollinator visitation. However, the mechanisms underlying the intraspecific variations of UV bullseye size remain largely unknown. We analyse the ecological consequences and genetic basis of floral UV bullseye size variation in an important ...

ABSTRACT Hydroxycinnamoyl tyramine conjugates are phenolamides produced by plants in response to pathogen attack and biotic stresses. Their proposed mechanisms of action include cytotoxicity towards pathogens, cell wall reinforcement to restrict pathogen proliferation, and signaling activity to trigger general stress responses.
