Variation in flower size and shape of Impatiens capensis is correlated with urbanization in Montreal, Canada. [PDF]

open access: yesEcol Evol, 2023
We found that the flower shape and size of the jewelweed is correlated with urbanization. Urban populations tend to have smaller flowers and sepals with shorter spurs. These changes are partly explained by vegetation cover and by variations in pollinator communities.

Pollen Exposed to Aerial Pesticide Spray Is a Major Exposure Pathway for Stingless Bees [PDF]

open access: yesEcol Evol
We conducted a molecular ecology experiment to determine foraging of stingless bees and potential exposure routes for aerially applied pesticides. We found that 27% of forager bees brought back Bti to the hive, and that this is a major route for pesticide exposure.

Differential adaptive RNA editing signals between insects and plants revealed by a new measurement termed haplotype diversity. [PDF]

open access: yesBiol Direct, 2023
Background C-to-U RNA editing in plants is believed to confer its evolutionary adaptiveness by reversing unfavorable DNA mutations. This “restorative hypothesis” has not yet been tested genome-wide.
