Achtymichuk, Jamin N.

Increasing agricultural intensification threatens to strain already degrading global soil resources while simultaneously escalating anthropogenic greenhouse gas emissions. Loss of soil organic matter (SOM) from agroecosystems is a major cause of soil degradation and a source of considerable...

The edge or perimeter of a wildland fire is an important characteristic that marks the extent of land area that has burned. It is not only an ecological boundary, but also an administrative way of documenting the direct impact of a wildfire. Weather has a well-established influence on fire...

Databases of high-resolution interpolated climate data are essential for climate change research, such as analyzing impacts of climate extreme events on biological systems and the development of climate change adaptation strategies for managed and natural ecosystems. To enable such efforts, this...

Thawing permafrost in northern regions threatens to increase the downstream delivery of mercury (Hg) and its organic form, methylmercury (MeHg). Permafrost thaw may mobilize large Hg and dissolved organic carbon (DOC) stores from permafrost soils. Once mobilized, inorganic Hg (Hg(II)) can be...

Open-pit mining of oil sands in Alberta, Canada, has resulted in a large-scale land disturbance of the boreal forest ecosystem and produced large amounts of tailings. To improve the effectiveness of the tailings solidification process and to make the tailings less harmful to vegetation, the novel...
