“…Dried soil was powdered and used for elementary CHN analysis (Carlo Erba CHNS-O-meter, EA 1108). Phosphorus was determined in dried material by the colorimetric meta-vanadate method, and other elements were determined by atomic absorption spectroscopy (Tatur et al 1997). Ash content was obtained by weighing the residue after combustion at 450°C.…”

Glacier forelands are excellent sites in which to study microbial succession because conditions change rapidly in the emerging soil. Development of the bacterial community was studied along two transects on lateral moraines of Ecology Glacier, King George Island, by culture-dependent and culture-independent approaches (denaturating gradient gel electrophoresis). Environmental conditions such as cryoturbation and soil composition affected both abundance and phylogenetic diversity of bacterial communities. Microbiocenosis structure along transect 1 (severe cryoturbation) differed markedly from that along transect 2 (minor cryoturbation). Soil physical and chemical factors changed along the chronosequence (time since exposure) and influenced the taxonomic diversity of cultivated bacteria, particularly along transect 2. Arthrobacter spp. played a pioneer role and were present in all soil samples, but were most abundant along transect 1. Cultivated bacteria isolated from transect 2 were taxonomically more diverse than those cultivated from transect 1; those from transect 1 tended to express a broader range of enzyme and assimilation activities. Our data suggest that cryoturbation is a major factor in controlling bacterial community development in postglacial soils, shed light on microbial succession in glacier forelands, and add a new parameter to models that describe succession phenomena.

“…Within the occupied penguin rookeries soils can contain high levels of organic acids such as oxalic, acetic, propionic and succinic acids (Roser et al 1994). The surface layer of soils of active penguin rookeries contains fresh and leached guano underlain by aluminium-iron phosphatic clay (Tatur et al 1997). It is generally entirely devoid of vegetation because of toxic overmanuring and active trampling.…”

This paper presents the results of a biodiversity study of microfungi in ornithogenic soils from Beaufort Island (Ross Sea, continental Antarctic). During the 2004/05 austral summer, we sampled a wide range of soil habitats from an abandoned penguin rookeries to examine the biodiversity of soil microfungi. Beaufort Island is predominantly ice and snow covered, isolated, difficult to access and known to have been visited only infrequently. Warcup's soil plating method was used for fungal cultivation. A total of ten fungal taxa were isolated, consisting of seven ascomycetes, two anamorphic fungi and one yeast. In terms of their thermal classes, a total of four psychrophilic, five psychrotolerant and 1 mesophilic fungi were isolated. Thelebolus microsporus, Geomyces sp. and Thelebolus sp. were the most common isolated fungi. Internal Transcribed Spacer (ITS) and 18S rDNA sequences were obtained from 17 fungal isolates, confirming their identification as Thelebolus microsporus, Thelebolus sp., Phoma herbarum and Geomyces sp.
