Global climate change has led to profound alterations of the Arctic environment and
ecosystems, with potential secondary effects on mercury (Hg) within Arctic biota. This review …

Methylmercury contamination of fish is a global threat to environmental health. Mercury (Hg)
monitoring programs are valuable for generating data that can be compiled for spatially …

Mercury (Hg) bioaccumulation in fish poses well-known health risks to wildlife and humans
through fish consumption. Yet fish Hg concentrations are highly variable, and key factors …

Niche segregation between introduced and native fish in Lake Nahuel Huapi, a deep
oligotrophic lake in Northwest Patagonia (Argentina), occurs through the consumption of …

Understanding and preserving intraspecific diversity (ISD) is important for species
conservation. However, ISD units do not have taxonomic standards and are not universally …

Resource polymorphism, whereby ancestral trophic generalists undergo divergence into
multiple specialist morphs, is common in salmonid fish populations inhabiting subarctic …

Sex plays an important role in the kinetics and dynamics of methylmercury in some animals.
Although fish is the main source of mercury exposure to consumers, the role of sex in fish-Hg …

Estuaries are transitional habitats characterized by complex biogeochemical and ecological
gradients that result in substantial variation in fish total mercury concentrations (THg). We …

Several species found in the Bering Sea show significant spatial variation in total mercury
concentrations ([THg]) longitudinally along the Aleutian Island chain. We assessed [THg] in …

The central nervous system is a critical target for Hg toxicity in all living organisms. Total Hg
(THg) was determined in brain and muscle samples of 165 specimens of eight species of …
