Biodiversity in mountain soils above the treeline
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

The stepwise rise of angiosperm‐dominated terrestrial ecosystems
ABSTRACT Angiosperms are the most diverse and abundant plant taxon today and dominate the majority of Earth's terrestrial ecosystems. They underwent rapid divergence and biogeographic expansion from the early to the middle Cretaceous. Yet, transformative ecosystem change brought about by the increased ecological dominance of angiosperms unfolded ...

Abstract This study shares over 25 years of weather and climate data collected from Iceland's glaciers. Since 1994, scientists have recorded weather observations from stations installed on the glaciers. These records help understand how the local climate is changing and implications for glacier melt. The weather station network covers many parts of the

Abstract The presence and nature of marine ice in ice shelves is important, yet difficult to determine. We present transient electromagnetic results spanning 10 km across a suture zone of Larsen C Ice Shelf (LCIS), Antarctica, supported by central borehole measurements. Our results indicate the presence of two ice‐shelf layers.

Abstract The subduction of the Chile Ridge beneath South America beginning 12–16 Myr ago opened a gap in the subducting slab beneath southern Patagonia, which migrated northward and is located today at 46°S. Geodynamic processes associated with the slab window are poorly understood.

Antarctic sea ice multidecadal variability triggered by Southern Annular Mode and deep convection
Antarctic sea ice exerts great influence on Earth’s climate by controlling the exchange of heat, momentum, freshwater, and gases between the atmosphere and ocean.
