Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

open access: yesBiological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Genetic structure of declining chinstrap penguin (Pygoscelis antarcticus) populations from South Shetland Islands (Antarctica) [PDF]

open access: yes, 2012
Seabirds and their response to climate perturbations are important bioindicators of changes in Antarctic ecosystems. During 30 years of observations of two chinstrap penguin (Pygoscelis antarcticus) colonies, one on King George Island and the other on ...

Lateral flexure of Erebus Ice Tongue due to ocean current forcing and fast ice coupling

open access: yesJournal of Glaciology
Ice tongues are unconfined by land on their lateral margins and are sensitive to external forcing from the ocean. They are found sporadically around the Antarctic coast but are common in the western Ross Sea.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Incorporation of particulates into accreted ice above subglacial Vostok lake, Antarctica [PDF]

open access: yes, 2005
The nature of microscopic particulates in meteoric and accreted ice from the Vostok (Antarctica) ice core is assessed in conjunction with existing ice-core data to investigate the mechanism by which particulates are incorporated into refrozen lake water.

Influence of sea surface temperature in the tropics on the Antarctic sea ice under global warming

open access: yesЛëд и снег, 2019
Sea ice fields in the Antarctic, in contrast to the Arctic ones, did not show a reduction in observed global warming, whereas the global climate models indicate its certain decrease.

Purification of crude cellulase obtained from Aspergillus foetidus and its immobilization in agar xerogel: A comparative study with commercial cellulase immobilized in similar support

open access: yesFood Biomacromolecules, EarlyView.
Agar xerogel was used to immobilize cellulase. Properties of partially purified cellulase from Aspergillus foetidus and commercial cellulase were compared after immobilization. Abstract This research study is a comparative study of the characteristics of partially purified cellulase produced from Aspergillus foetidus through solid‐state fermentation ...

Animals, colonialism and Antarctica

open access: yes
This chapter uses the specific case of Antarctica to think more broadly about how the treatment of animals can reveal colonial attitudes and logics, but also whether, in the absence of an Indigenous human population, animals have been (or can be ...

Potential of Seaweed to Improve the Quality and Shelf Life of Fish and Fishery Products

open access: yesFood Safety and Health, EarlyView.
Growing global demand for safe fish preservation has increased interest in natural alternatives. Seaweed‐derived bioactive compounds possess antioxidant and antimicrobial properties that enhance fish quality, safety, and shelf life. These sustainable preservatives may reduce spoilage and synthetic preservative use, though further research ...

A Reassessment of Petrochemistry of ~1.2 Ga Tonalitic Rocks of the Northern Tugela Terrane, Natal Metamorphic Belt, South Africa: Further Constraints on the Evolution of This Belt

open access: yesGeological Journal, EarlyView.
Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.
