Arid ecosystems cover∼ 40% of the Earth's terrestrial surface and store a high proportion of
the global nitrogen (N) pool. They are low-productivity, low-biomass, and polyextreme …

The Antarctica Dry Valleys are regarded as the coldest hyperarid desert system on Earth.
While a wide variety of environmental stressors including very low minimum temperatures …

The McMurdo Dry Valleys are the largest ice-free region in Antarctica and are critically at risk
from climate change. The terrestrial landscape is dominated by oligotrophic mineral soils …

The metaviromes of two distinct Antarctic hyperarid desert soil communities have been
characterized. Hypolithic communities, cyanobacterium-dominated assemblages situated on …

Desert ecosystem is generally considered as a lifeless habitat with extreme environmental
conditions although it is colonized by extremophilic microorganisms. Cyanobacteria …

It has been established that maize/soybean intercropping can improve nitrogen use
efficiency. However, few studies have addressed how maize/soybean intercropping affects …

Drylands are the largest terrestrial biome on Earth and a ubiquitous feature is desert
pavement terrain, comprising rocks embedded in the mineral soil surface. Quartz and other …

In hyperarid ecosystems, macroscopic communities are often restricted to cryptic niches,
such as hypoliths (microbial communities found beneath translucent rocks), which are …

Abstract The Namib Desert is considered the oldest desert in the world and hyperarid for the
last 5 million years. However, the environmental buffering provided by quartz and other …

The Antarctic continent is widely considered to be one of the most hostile biological habitats
on Earth. Despite extreme environmental conditions, the ice-free areas of the continent …
