We present pollen and spore analysis from a peat-bog section from southwestern Isla de los Estados (Staaten Island), Tierra del Fuego to better understand late-Holocene environmental change in southernmost Patagonia. The island's position as the easternmost landmass at the southernmost of South America, places it squarely within the influence of the southern westerly winds (SWW) and the Antarctic Circumpolar Current, and so makes the island a unique location to document the palaeoecological response ...

Strain delineation of the emerging opportunistic pathogen Clavispora lusitaniae was studied using 12 strains, including two strains of known opposite mating type, CBS 6936 (h+) and CBS 5094 (h-), and 10 strains isolated between 1998 and 2001 from immunocompromized patients. This retrospective study assessed the occurrence of C. lusitaniae subtypes within and among hospitals, and in outpatients who were regularly screened for fungal infections in the course of radio-chemotherapy. Strain typing was ...

A pollen record was obtained from a coring site at La Correntina mire (54°33′S, 66°59′W, 206 m a.s.l.) to the east of Lago Fagnano, centre of Tierra del Fuego. The results indicate that the valley bottom was free of ice shortly before 15,400 cal bp. Pioneer vegetation included dwarf shrub heaths, grasses and herbs with sparsely distributed Nothofagus trees, indicative of dry conditions. Nothofagus expanded by 10,000 cal bp and the forest-steppe ecotone was established by 9,400 cal bp, implying warm ...

We analyzed a peat-bog sequence from the central region of Tierra del Fuego, southernmost Patagonia, to reconstruct the environmental changes over the past 15,000 years. Postglacial vegetation was mainly composed by grasslands and shrubby communities with sparsely distributed Nothofagus trees under dry conditions. The predominance of Glomus sp. and Gelasinospora sp. may also indicate less humid conditions related to the steppe communities. The presence of herbivorous grazers is suggested by the ...
