abstract Long-term observations and experiments in diverse drylands reveal how
ecosystems and services are responding to climate change. To develop generalities about …

Roughly six petagrams of organic carbon are stored within ice worldwide. This organic
carbon is thought to be of old age and highly bioavailable. Along with storage of ancient and …

Amplified climate change in polar regions is significantly altering regional ecosystems, yet
there are few long-term records documenting these responses. The McMurdo Dry Valleys …

Cyanobacterial mat communities are the main drivers of primary productivity in the McMurdo
Dry Valleys, Antarctica. These microbial communities form laminar mats on desert pavement …

Microbial consortia dominate glacial meltwater streams from polar regions, including the
McMurdo Dry Valleys (MDV), where they thrive under physiologically stressful conditions. In …

Abstract Streams in the McMurdo Dry Valleys (MDVs) of Antarctica moderate an important
hydrologic and biogeochemical connection between upland alpine glaciers, valley‐bottom …

Extreme climate and weather events, such as a drought, hurricanes, or ice storms, can
strongly imprint ecosystem processing and may alter ecosystem structure. Ecosystems in …

Hydrologic connectivity has received great attention recently as our conceptual models of
watersheds and water quality have evolved in the past several decades. However, the …

We use correlative field studies and high-resolution multispectral remote sensing data from
the WorldView-2 instrument to estimate the abundance of photosynthetically active biomass …

Microbial mats are abundant in many alpine and polar aquatic ecosystems. With warmer
temperatures, new hydrologic pathways are develo** in these regions and increasing …
