Differing preferences of Antarctic soil nematodes for microbial prey [PDF]

, 2004
We tested the preferences of three nematode taxa, Geomonhystera villosa, Plectus spp. and Teratocephalus spp., extracted from moss at Signy Island in the Maritime Antarctic, for two microalgae, three microfungi and six heterotrophic bacteria, each also ...

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

Ecography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Moss diatoms show regional structuring, high potential endemism, and an inverse latitudinal diversity gradient in the Arctic

Ecography, EarlyView.
Microorganisms perform essential functions in Arctic terrestrial ecosystems. Yet, their ecology and biogeography are poorly understood, despite being necessary to predict microbial responses to future climate change. Here, we provide the first large‐scale floristic and biogeographic study of the moss diatom flora in the tundra regions of the North ...

Freshwater diatoms of the Ecology Glacier foreland, King George Island, South Shetland Islands [PDF]

Polish Polar Research, 2018
Diatom assemblages from small pools and creeks on the Ecology Glacier forefield have been investigated. It is the first study in the Admiralty Bay region after the thorough taxonomic revision of the non-marine Antarctic diatom flora.

Setting a precautionary catch limit for Antarctic krill [PDF]

, 2002
A revised precautionary catch limit for Antarctic krill (Euphausia superba) in the Scotia Sea of 4 million tons was recently adopted by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).

Low‐temperature soft electrochemical actuator based on hierarchically structured polypyrrole membranes for subzero operation

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
