Agaricales (Basidiomycota) Fungi in the South Shetland Islands, Antarctica

Abstract

Fungi are the most important nutrient cycling organisms in any ecosystem

Rapid denudation processes in cryptogamic communities from Maritime Antarctica subjected to human trampling

“…Most of the mosses found in the samples from the three communities are common on Livingston Island (Sancho et al . 1999, Putzke & Pereira 2001, Ochyra et al . 2008), but two of them were reported for the first time for the island: Pohlia wahlenbergii , already known from other islands in the South Shetland Islands, and Brachythecium subpilosum , a new report for the archipelago (Lara & Pertierra 2012).…”

Comparative study of moss diversity in South Shetland Islands and in the Antarctic Peninsula

“…Victoria and Pereira (2007) showed that the highest temperatures and weak winds were found in the Admiralty Bay, generating a distinct microclimate in this area, in comparison to the rest of the island, and thus can be reflecting in higher plant diversity in this area. The Elephant and Nelson Island, despite the differences in the individuals sampled, are both often related as islands with a moderate moss diversity, where no specific occurrences were found (Putzke et al, 1998;Pereira and Putzke 1994), unlike King George Island that has a known occurrence of endemic species cited in the literature (Ochyra, 1998). On the other hand, the moss flora from King George and Elephant Island are found to have higher similarities (Figure 3), even though Nelson Island is nearer to King George Island.…”

Do new records of macrofungi indicate warming of their habitats in terrestrial Antarctic ecosystems?

“…Spore measurements (minimum, average and maximum length and width; length-width quotient Q l/w) are based on values obtained from at least 10 randomly selected spores in lateral view. For species identification and retrieving information about their ecology and distribution, the following references were used: Elborne 2012, Guminska et al 1994, Horak 1982, Høiland 1976, Gminder and Krieglsteiner 2001, Laessøe 2012, Pegler et al 1980, Putzke and Pereira 1996, Putzke et al 2012, Redhead 1984, Segedin 1994, Senn-Irlet and Moreau 2003, Singer 1956, Vizzini et al 2012, among others. Current names and basionyms were assigned to species mostly according to Index Fungorum [1].…”
