Environmental context Mercury, in its methylated form, is a neurotoxin that biomagnifies in
marine and terrestrial foodwebs leading to elevated levels in fish and fish-eating mammals …

16S rRNA gene (rrs) clone libraries were constructed from two snow samples (May 11,
2007 and June 7, 2007) and two meltwater samples collected during the spring of 2007 in …

Microbial ecologists can now start digging into the accumulating mountains of metagenomic
data to uncover the occurrence of functional genes and their correlations to microbial …

Snow and ice environments cover up to 21% of the Earth's surface. They have been regarded
as extreme environments because of their low temperatures, high UV irradiation, low …

Alpine soils are warming strongly, leading to profound alterations in carbon cycling and
greenhouse gas budgets, mediated via the soil microbiome. To explore microbial responses to …

Biochemical and physiological responses of walleye (Sander vitreus) and perch (Perca
flavescens) were studied in four Canadian boreal forest lakes representing a mercury (Hg) …

The atmosphere is an important route for transporting and disseminating microorganisms
over short and long distances. Understanding how microorganisms are distributed in the …

The use of biodiesel as a transportation fuel and its growing mandatory blending percentage
in diesel increase the likelihood of contaminating groundwater with diesel/biodiesel blends. …

Arctic snowpacks are often considered as temporary reservoirs for atmospheric mercury (Hg)
deposited during springtime deposition events (AMDEs). The fate of deposited species is of …

Seasonal snow is an active media and an important climate factor that governs nutrient transfer
in Arctic ecosystems. Since the snow stores and transforms nutrients and contaminants, it …
