  • The highest neonicotinoid concentrations reported in Ontario row crop sites (0.23 µg/L total) are substantially lower than California concentrations reported by Starner and Goh; comparative geographic sampling across multiple agroecological regions with standardized methods and detection limits is needed to characterize how regional agricultural practices affect neonicotinoid contamination available to barn swallows.

    Quantifying insecticide exposure across an agricultural landscape gradient using barn swallows as a wildlife indicator · 2026 · DOI

  • Urban sources of aquatic neonicotinoid contamination (from turf and ornamental imidacloprid applications) have been identified but not systematically quantified or compared to agricultural sources in the context of barn swallow habitat use; integrated sampling across urban-rural landscape gradients is required to determine the relative contribution of each source to overall wildlife exposure.

    Quantifying insecticide exposure across an agricultural landscape gradient using barn swallows as a wildlife indicator · 2026 · DOI

  • The effects of cobalt nanoparticles on endocrine disruption in fish are not well understood. There is a need to develop novel strategies to mitigate the effects of environmental stresses on fish reproduction.
