Drivers of fish biodiversity in a rapidly changing permafrost landscape
Freshwater Biology, 2021Abstract Rapid environmental change occurring in northern permafrost regions may have profound implications for fish biodiversity but remains poorly understood. Climate change, increasing human development, and resultant permafrost thaw may combine to alter the quality and quantity of fish habitat including reductions in preferred thermal habitat ...

Threshold loss of discontinuous permafrost and landscape evolution
Global Change Biology, 2017AbstractThis study demonstrates linkages between the 1997/1998 El Niño/Southern Oscillation index and a threshold shift to increased permafrost loss within a southern Taiga Plains watershed, Northwest Territories, Canada. Three‐dimensional contraction of permafrost plateaus and changes in vegetation structural characteristics are determined from ...

Soil temperature observations in permafrost regions are sparse, which limits our understanding and ability to map permafrost conditions at high spatial resolutions. In this study, we measured near‐surface soil temperatures (Tnss) at 107 sites from August
