Cryptococcus species (Basidiomycota) were isolated as the predominant yeast from glacial biomes of both Patagonia (Argentina) and the Svalbard archipelago (Norway). For a selected group of Cryptococcus belonging to Tremellales, assimilative profile, production of extracellular hydrolytic enzymes and ribosomal DNA internal transcribed spacer and large subunit (D1/D2) sequences were analysed. Cryptococcus victoriae, which was originally described from Antarctica, was the most frequently found species at both locations. High variability within the species was observed and described at the genotypic and phenotypic levels, two newly described species were found in both Patagonia and Svalbard: Cryptococcus fonsecae and Cryptococcus psychrotolerans. Two other new species were found only in Patagonia: Cryptococcus frias and Cryptococcus tronadorensis. Three additional new taxa were found, but they are not named as they were only represented by single isolates.

“…1b, inset) and the feeding behavior of the moths, which do not feed on cold nights or during the colder periods of the night (e.g., Martínez del Río and Bfflrquez 1986). Fermentation by yeasts in the nectar (e.g., Herzberg et al 2002) could also add to the basal floral CO 2 release (Drawert et al 1987), and this supplementary production of CO 2 may also diminish with the drop in temperature during the night.…”

Floral CO2 emission may indicate food abundance to nectar-feeding moths

As part of a study of the roles of the sensory subsystem devoted to CO(2) in the nectar-feeding moth Manduca sexta, we investigated CO(2) release and nectar secretion by flowers of Datura wrightii, a preferred hostplant of Manduca. Datura flowers open at dusk and wilt by the following noon. During the first hours after dusk, when Manduca feeds, the flowers produce considerable amounts of nectar and emit levels of CO(2) that should be detectable by moths nearby. By midnight, however, both nectar secretion and CO(2) release decrease significantly. Because nectar production requires high metabolic activity, high floral CO(2) emission may indicate food abundance to the moths. We suggest that hovering moths could use the florally emitted CO(2) to help them assess the nectar content before attempting to feed in order to improve their foraging efficiency.

“…The species seems to have a global and ubiquitous distribution. It was isolated from volcanic soil in Iceland (Vishniac, 2002), from soil of forest in Austria (Wuczkowski and Prillinger, 2004), as well as from floral nectar in Germany (Herzberg et al, 2002). In view of the various substrates from which it has been isolated and because of its low frequency reported here an association with grapes seems unlikely.…”
