“…The first mycological investigations of soil in the north‐west Alps were reported in 1957, 1960, and 1974 . Subsequently, data are rare and scattered, with the most recent being on the microfungi living in soil hummocks in the Italian Rhaetian Alps . In the Lombardy region of the Italian Alps, where the present study was conducted, there is clear evidence that glaciers have retreated due to transient climate change and, during the latest glaciological campaign (2008–2009), this phenomenon was observed in 41 out of the 54 monitored sites .…”

Periglacial areas are one of the least studied habitats on Earth, especially in terms of their fungal communities. In this work, both molecular and culture-dependent methods have been used to analyse the microfungi in soils sampled on the front of the East Dosdè Glacier (Valtellina, Northern Italy). Although this survey revealed a community that was rich in fungal species, a distinct group of psychrophilic microfungi has not been detected. Most of the isolated microfungi were mesophiles, which are well adapted to the sensitive climatic changes that occur in this alpine environment. A discrepancy in the results that were obtained by means of the two diagnostic approaches suggests that the used molecular methods cannot entirely replace traditional culture-dependent methods, and vice versa.

“…Complexes of bacteria, fungi (including saprobic micro fungi) and soil fauna play an important role in decomposing leaf litter (Persiani et al 2011). For the recycling of nutrients, the decomposition of living and logged trees along with fallen litter is critical and is primarily carried out by fungi, especially the members of basidiomycetes (Saitta et al 2011).…”

Litter decay is a significant part of carbon budget. Due to strong environmental control, the changes in the environment may drastically influence the litter decay rates. Litter decomposition of eight dry tropical woody species, viz. Shorea robusta, Buchanania lanzan, Diospyros melanoxylon, Lagerstroemia parviflora, Lannea coromandelica, Terminalia tomentosa, Holarrhena antidysenterica and Lantana camara was studied to document the effect of intra-annual changes in the environment. Litter decomposition was monitored at monthly intervals at five sites using litter bag technique over an annual cycle in a dry tropical deciduous forest of Vindhyan highland, India. Weight loss differed among species and through months, and ranged from 15.38% in L. camara at Kotwa site in January to 30.72% in T. tomentosa at Hathinala site in August. Peak weight loss occurred in August and averaged 46.2% across species and sites. Nitrogen and phosphorus mineralization rates also varied significantly from species to species. T. tomentosa having higher nitrogen content and lower C/N ratio than other species exhibited faster weight loss. Nitrogen and phosphorus contents of litter showed significant positive correlation with weight loss. C/N ratio was negatively related to decay constant, and the weight loss was positively related to the soil surface temperature as well as soil moisture content.

“…Arctic areas and glaciers of high-mountain complexes, such as Himalaya, Alps and Andes are glacial areas which also represent rich sources of psychrophiles and psychrotolerants (Thomas-Hall et al 2010;Turchetti et al 2011). The viability of microorganisms in cold environments has been the focus of interest for many years, and glacial ice is an excellent preservation matrix for microbial life (Newsham 2012); the longevity of microorganisms entrapped in ice (including those from alpine environments) has consequently become a subject of study (Catranis & Starmer 1991;Abyzov 1993;Persiani et al 2011;among others). Physiological mechanisms conferring cold tolerance on fungi are complex and not yet fully understood; they include increases in unsaturated membrane lipids (Russell 2008), the production of RNA chaperones to suppress the formation of undesired secondary RNA structures (Kwak et al 2011), the synthesis of antifreeze (García-Arribas et al 2007) and cold shock proteins (Horn et al 2007), as well as cold-active enzymes (Gatti-Lafranconi et al 2010).…”

A wide range of cold environments exist, with an equally broad variety of fungi and yeasts that have adapted to such environments. These adaptations, which affect membranes, enzymes and other cellular components, such as radical scavenging molecules, display a great potential for exploitation in biotechnology. Alterations have been detected in membrane lipids, with an increase in fatty acid unsaturated bonds that enhance their fluidity. We report new data on the different phospholipid composition in membrane lipids in the same fungal species from both Antarctic and temperate regions. The decrease in temperature causes intracellular oxidative stress by inducing the generation of reactive oxygen species. We report the results of the first analysis of the non-enzymatic antioxidant response and phenolic compound production by an Antarctic strain of Geomyces pannorum. A survey on yeasts from the cryosphere is reported with a focus on their adaptation to a cold environment. Some studies have shown that the number of macrofungi in glacier forefronts rises as deglaciation increases. The survival success of many plants in such areas may be attributed to their mycorrhizal associations. We highlighted the macrofungal biodiversity of some Italian alpine habitats, in which we Inocybe microfastigiata, Laccaria montana and Lactarius salicisherbaceae were recorded for the first time in Lombardy (Italy).
