Diagnosing ice sheet grounding line stability from landform morphology
The Cryosphere, 2018 . The resilience of a marine-based ice sheet is strongly governed by the stability of its grounding lines, which are in turn sensitive to ocean-induced melting, calving, and flotation of the ice margin.

Primulina marmorata (Gesneriaceae), a new species from northern Guangxi, China
Nordic Journal of Botany, EarlyView.Primulina marmorata, a new species of Gesneriaceae from the limestone areas of Siding Town, Rong'an County, liuzhou City, Guangxi, China, is described and illustrated here. It morphologically resembles P. yungfuensis in leaf blades. Still, it can be easily distinguished from the latter by noting a combination of characteristics, especially in its ...
