Published in 2017 at "Environmental toxicology and chemistry"

DOI: 10.1002/etc.3688

Abstract: Variation in avian bilateral symmetry can be an indicator of developmental instability in response to a variety of stressors, including environmental contaminants. The authors used composite measures of fluctuating asymmetry to examine the influence of… read more here.

Published in 2019 at "Environmental toxicology and chemistry"

DOI: 10.1002/etc.4430

Abstract: Feathers are widely used to represent mercury contamination in birds. Yet, few recommendations exist that provide guidance for using bird feathers in mercury monitoring programs. We conducted a literature review and 5 experiments to show… read more here.

Published in 2019 at "Environmental toxicology and chemistry"

DOI: 10.1002/etc.4535

Abstract: Wetland environments provide numerous ecosystem services but also facilitate methylmercury production and bioaccumulation. We developed a wetland management technique to reduce methylmercury concentrations in wetland fish and water. We physically modified seasonal wetlands by constructing… read more here.

Published in 2020 at "River Research and Applications"

DOI: 10.1002/rra.3625

Abstract: Peaking hydroelectric facilities release water from dams to match energy production with demand, often on a daily cycle. These fluctuating flows downstream can exert several potential stressors on organisms that may inhibit their growth, indirectly… read more here.

Published in 2021 at "Ecotoxicology"

DOI: 10.1007/s10646-020-02326-w

Abstract: Identifying waterbodies where fish methylmercury concentrations are elevated is critical for development of consumption guidelines. However, mercury concentrations vary among waterbodies and fishes due to a suite of environmental conditions and detection of elevated mercury… read more here.

Published in 2020 at "Chemosphere"

DOI: 10.1016/j.chemosphere.2020.129233

Abstract: Total mercury concentrations ([THg]) in muscle were determined in commercial finfish and elasmobranchs from Baja California Sur (BCS), Mexico to evaluate dietary Hg exposure for BCS communities, including the relationship of trophic ecology, length and… read more here.

Published in 2021 at "Chemosphere"

DOI: 10.1016/j.chemosphere.2021.130470

Abstract: Methylmercury concentrations vary widely across geographic space and among habitat types, with marine and aquatic-feeding organisms typically exhibiting higher mercury concentrations than terrestrial-feeding organisms. However, there are few model organisms to directly compare mercury concentrations… read more here.

Published in 2020 at "Environmental research"

DOI: 10.1016/j.envres.2020.110629

Abstract: Biogeochemical conditions and landscape can have strong influences on mercury bioaccumulation in fish, but these effects across regional scales and between sites with and without point sources of contamination are not well understood. Normal means… read more here.

Published in 2022 at "Environmental science & technology"

DOI: 10.1021/acs.est.1c07633

Abstract: Mercury (Hg) is highly toxic in its methylated form (MeHg), and global change is likely to modify its bioavailability in the environment. However, it is unclear how top predators will be impacted. We studied blood… read more here.
