'Arctic Crashes:' Revisiting the Human-Animal Disequilibrium Model in a Time of Rapid Change
Project
Organization:
This study examined data on the status of three northern mammal species – caribou/reindeer, Pacific walrus, and polar bear—during two decades of the ongoing Arctic warming. The emerging record may be...
'Arctic Crashes:' Revisiting the Human-Animal Disequilibrium Model in a Time of Rapid Change
Resource
Abstract The paper introduces a new vision advanced by the recent project, Arctic People and Animal Crashes: Human, Climate and Habitat Agency in the Anthropocene (2014–2015) developed at the...
Improving the Fire Weather Index System for Peatlands using Peat-Specific Hydrological Input Data
Resource
The Canadian Fire Weather Index (FWI) system, even though originally developed and calibrated for an upland Jack pine forest, is used globally to estimate fire danger for any fire environment. However...

Prompt Rewetting of Drained Peatlands Reduces Climate Warming Despite Methane Emissions
Resource
Peatlands are strategic areas for climate change mitigation because of their matchless carbon stocks. Drained peatlands release this carbon to the atmosphere as carbon dioxide (CO2). Peatland...
Satellite Determination of Peatland Water Table Temporal Dynamics by Localizing Representative Pixels of A SWIR-Based Moisture Index
Resource
The OPtical TRApezoid Model (OPTRAM) is a physically-based approach for remote soil moisture estimation. OPTRAM is based on the response of short-wave infrared (SWIR) reflectance to vegetation water...
