PROTEOMICS, EarlyView.ABSTRACT Fragilariopsis cylindrus is a key diatom in the Southern Ocean, where low iron and manganese availability constrain primary production and biogeochemical activity. The molecular mechanisms used by polar diatoms, including F. cylindrus, to cope with trace metal limitations remain largely unexplored.

Effects of heavy metals on bioremediation of diesel by Antarctic microalga Tritostichococcus sp. [PDF]
Polish Polar ResearchHydrocarbon spillage has long been a concern in Antarctica as it can result in detrimental effects on Antarctic biota and ecosystems. Bioremediation, using microorganisms such as microalgae, represents one of the most effective and least damaging methods

PLANTS, PEOPLE, PLANET, EarlyView.In response to Chile's public policy to establish a national biodiversity inventory and monitoring system, we launched the HerbarioDigital.cl portal. We have digitised over 120,000 specimens representing more than 3,900 species from two Chilean herbaria, integrating them through a curated local taxonomic index.

Windows of opportunity in subseasonal weather regime forecasting: A statistical–dynamical approach
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study explores how the atmospheric state at initialisation creates windows of opportunity for improving week 3 forecasts of weather regime activity. Greenland blocking activity increases following Madden–Julian Oscillation phases 7, 8, and 1 and weak stratospheric polar vortex states, revealing patterns exploitable by statistical models.
