Rapid atmospheric warming since the mid-twentieth century has increased temperature-
dependent erosion and sediment-transport processes in cold environments, affecting food …

The physical and chemical changes that accompany permafrost thaw directly influence the
microbial communities that mediate the decomposition of formerly frozen organic matter …

The Arctic is a water-rich region, with freshwater systems covering about 16% of the northern
permafrost landscape. Permafrost thaw creates new freshwater ecosystems, while at the …

During recent years, many studies have shown that different processes including drift,
environmental selection and dispersal can be important for the assembly of bacterial …

Permafrost thawing results in the formation of thermokarst lakes, which are biogeochemical
hotspots in northern landscapes and strong emitters of greenhouse gasses to the …

Although the habitability of early Mars is now well established, its suitability for conditions
favorable to an independent origin of life (OoL) has been less certain. With continued …

The alpine meadow ecosystem, as the main ecosystem of the Qinghai-Tibet Plateau, has
been heavily degraded over the past several decades due to overgrazing and climate …

While the sentinel nature of freshwater systems is now well recognized, widespread
integration of freshwater processes and patterns into our understanding of broader climate …

Harmful cyanobacterial blooms are an increasing problem at many locations throughout the
world but are rarely reported in aquatic habitats at high latitudes. Shallow lakes are a major …

Lakes and ponds derived from thawing permafrost are strong emitters of carbon dioxide and
methane to the atmosphere, but little is known about the methane oxidation processes in …
