“…Thus, extremophilic species are expected to be stenobionts or specialists that are found only in environments that are characterized by harsh physical and chemical conditions unfavourable for the majority of potential yeast colonists. In contrast, extremotolerant yeasts are eurybionts – species that are able to grow in various habitats and conditions, including some extreme environments (Yurkov & Pozo, ). Yeast communities in extreme environments are characterized by the presence of both stenobiont and eurybiont species with different abundances and frequencies, also in dependence on the level of selection exerted by the habitat and yeast adaptation aptitudes, and dispersal abilities.…”

“…liming. Acidic soils are widely distributed in nature (Bian, Zhou, Sun, & Li, 2013) and many soil-borne yeasts have demonstrated the ability to cope with these conditions (Yurkov & Pozo, 2017).Habitats characterized by alkaline pH values are equally challenging for yeast life. Alkali-tolerant yeasts have been isolated from soda-rich saline soils, frass, swamp, hot springs, alkaline lakes and hypersaline lakes (Lisichkina, Babeva, & Sorokin, 2003;Péter et al, 2017).…”

“…Soil yeasts of the genera Naganishia survive in dry sandy soil and species of the genus Solicoccozyma retain their viability in a dry state for as long as 9 months (reviewed in Yurkov & Pozo, 2017). In addition, several phylloplane-related yeasts exhibit resistance to dessiccation for over 2 months (Glushakova, Kachalkin, Zheltikova, & Chernov, 2015 (Raspor & Zupan, 2006).…”

Microorganisms are widely distributed in a multitude of environments including ecosystems that show challenging features to most life forms. The combination of extreme physical and chemical factors contributes to the definition of extreme habitats although the definition of extreme environments changes depending on one's point of view: anthropocentric, microbial-centric or zymo-centric. Microorganisms that live under conditions that cause hard survival are called extremophiles. In particular organisms that require extreme conditions are called true extremophiles while organisms that tolerate them to some extent are termed extremotolerant. Deviation of temperature, pH, osmotic stress, pressure and radiation from the common range delineates extreme environments. Yeasts are versatile eukaryotic organisms that are not frequently considered the toughest microorganisms in comparison with prokaryotes. Nevertheless extremophilic or extremotolerant species are present also within this group. Here a brief description is provided of the main extreme habitats and the metabolic and physiological modifications adopted by yeasts depending on their adverse conditions. Additionally the main extremophilic and extremotolerant yeast species associated with a few extreme habitats are listed.

“…Despite the range of strategies to prevent microbial colonisation of nectar, the evidence shows that floral nectar contains several species of highly adapted yeast and fungal communities [12,16,33,34] with the ability to alter the amino acid and sugar composition of the nectar [16,21,35]. Bacteria have previously been isolated, cultured and identified in a small number of floral nectar studies [36,26,37].…”

Background: Plants are critical to global environmental health and food production strategies; most plants utilise flowers as part of their reproduction cycle. Flowers attract pollinators using a range of complex strategies and floral nectar is an essential component of this attraction profile. Nectar is a nutrient rich liquid, containing a range of sugars, organic acids, amino acids, lipids and vitamins, found to be a suitable habitat for a wide range of fungi, but so far, limited bacterial diversity has been detected. Several antimicrobial properties and adverse environmental conditions, such as high osmotic pressure present in the nectar were thought to reduce bacterial numbers.Results: This study reports the next generation sequencing analysis of the bacterial and fungal diversity in flower nectar. This was achieved in four floral species native to the United Kingdom (Lamium album, white dead nettle; Narcissus pseudonarcissus, daffodil, Hyacinthoides non-scripta, English bluebell and Digitalis purpurea, the common foxglove). All flower species examined had a diverse bacterial and fungal populations present with a core microbiome detected, dominated by Proteobacteria and Firmicutes phyla, while Basidomycota were the most persistent fungal phyla in all of the floral nectar types sampled. However, many unique bacterial and fungal species were detected at lower abundances. Furthermore, in N. pseudonarcissus and D. purpurea floral nectar, the microbial diversity detected in the nectar between flowers exposed to the environment versus non-environment exposed flowers, was different.Conclusions: These results suggest that floral nectars in different plant species do contain a distinct microbiome and the individual flower microbial community diversity may be affected by floral nectar composition, insect visitation and other environmental factors.

Yeasts are ubiquitous in temperate forests. While this broad habitat is well‐defined, the yeasts inhabiting it and their life cycles, niches, and contributions to ecosystem functioning are less understood. Yeasts are present on nearly all sampled substrates in temperate forests worldwide. They associate with soils, macroorganisms, and other habitats and no doubt contribute to broader ecosystem‐wide processes. Researchers have gathered information leading to hypotheses about yeasts' niches and their life cycles based on physiological observations in the laboratory as well as genomic analyses, but the challenge remains to test these hypotheses in the forests themselves. Here, we summarize the habitat and global patterns of yeast diversity, give some information on a handful of well‐studied temperate forest yeast genera, discuss the various strategies to isolate forest yeasts, and explain temperate forest yeasts' contributions to biotechnology. We close with a summary of the many future directions and outstanding questions facing researchers in temperate forest yeast ecology. Yeasts present an exciting opportunity to better understand the hidden world of microbial ecology in this threatened and global habitat.
