AI Article Synopsis
- Fungal strains discovered in Victoria Land, Antarctica, belong to two new genera and species: Recurvomyces mirabilis and Elasticomyces elasticus.
- These fungi are phylogenetically linked to other extremophilic fungi found in dry habitats, whether cold or hot.
- The findings suggest ecological relationships with other fungi that thrive in harsh conditions, including those that can survive extreme acidity and salinity.
Article Abstract
Fungal strains isolated from rocks and lichens collected in the Antarctic ice-free area of the Victoria Land, one of the coldest and driest habitats on earth, were found in two phylogenetically isolated positions within the subclass Dothideomycetidae. They are here reported as new genera and species, Recurvomyces mirabilisgen. nov., sp. nov. and Elasticomyces elasticusgen. nov., sp. nov. The nearest neighbours within the clades were other rock-inhabiting fungi from dry environments, either cold or hot. Plant-associated Mycosphaerella-like species, known as invaders of leathery leaves in semi-arid climates, are also phylogenetically related with the new taxa. The clusters are also related to the halophilic species Hortaea werneckii, as well as to acidophilic fungi. One of the latter, able to grow at pH 0, is Scytalidium acidophilum, which is ascribed here to the newly validated genus Acidomyces. The ecological implications of this finding are discussed.

Article Synopsis
- The study assessed the organization and infrastructure of pharmaceutical services in the prison system of Rio Grande do Sul, identifying major deficiencies in the primary health care framework.
- Most prison units lacked designated pharmacy areas and standardized procedures, with 78.4% reporting no operational guidelines for pharmacy activities.
- Only a small percentage had a pharmacist on site, and many did not adequately monitor medication storage conditions or have proper medication dispensing processes in place, highlighting significant weaknesses in the system.
