Contrasting Dynamical Responses of Sympatric Caribou and Muskoxen to Winter Weather and Earlier Spring Green-up in the Arctic
Resource
Analyzed the population dynamics and offspring production of sympatric caribou and muskoxen in West Greenland over an 18-year period (2002–2019) during which the timing of spring green-up has advanced
Large Herbivores Facilitate the Persistence of Rare Taxa Under Tundra Warming
Resource
Ecological rarity, characterized by low abundance or limited distribution, is typical of most species, yet our understanding of what factors contribute to the persistence of rare species remains...
Monitoring Wetland Vegetation and Reclamation Across Space and Time
Resource
Measuring variability in natural processes requires rigorous data collection and could increase the cost of environmental monitoring for oil and gas operators. Recent advances in remote-sensing and...
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...
