Biogeography of Crustacea and Mollusca of the Subantarctic and Antarctic regions
, 1999 The Joint Magellan Victor Hensen Campaign in 1994 focused on the biogeographic relationships of the Antarctic and Magellan fauna. The Peracarida and Mollusca sampled at 18 stations in the Beagle Channel by means of an epibenthic sledge were compared with

FlexMat, EarlyView.A soft electrochemical actuator using a hierarchically structured polypyrrole membrane with coral‐like hollow vesicles achieves stable performance at −24°C. The unique architecture ensures continuous conductivity and rapid ion diffusion, resulting in large strain, low energy consumption, and high coulombic efficiency under subzero conditions. This work

Food Safety and Health, EarlyView.XSPH‐I exhibits excellent cellular antioxidant activity and cell protective effects. Four novel antioxidant peptides were screened from XSPH‐I peptide, and the newly synthetic peptide exhibits excellent antioxidant properties in vitro. ABSTRACT In this study, the antioxidant peptides (XSPH) from Xanthoceras sorbifolium oleifera were extracted and ...

An assessment of the spatial extent of polar dust using satellite thermal data
Scientific Reports, 2021 The effect of mineral dust aerosols and subsequent deposition in polar regions has historically been underestimated in climate models. Dust aerosols increase melt rates by reducing surface albedo and modifying atmospheric radiative properties.

The impact of the mixing properties within the Antarctic stratospheric vortex on ozone loss in spring [PDF]
, 2001 Calculations of equivalent length from an artificial advected tracer provide new insight into the isentropic transport processes occurring within the Antarctic stratospheric vortex. These calculations show two distinct regions of approximately equal area:

Global Change Biology Communications, EarlyView.Modeling of current and future spatial distribution of Antarctic lecideoid lichens shows that warming will strongly increase the potential habitat. Under three climate‐change scenarios, most fungal and algal partners are projected to expand inland. Overall, climate change drives widespread range shifts and promotes colonization of interior Antarctica ...
