BACKGROUND Airborne fungi are responsible for the majority of fungal infections in humans and animals. Outdoor air markedly influences the prevalence of fungal spore levels in indoor air and thus, it is the major source of fungal infections in indoor environments especially in hospitalized individuals. METHODS Using a settle plate method, air sampling (1092 air samples from 93 sampling sites ...

1. Decomposition of red maple (Acer rubrum) and rhododendron (Rhododendron maximum) leaves and activity of associated microorganisms were compared in two reaches of a headwater stream in Coweeta Hydrologic Laboratory, NC, U.S.A. The downstream reach was enriched with ammonium, nitrate, and phosphate whereas the upstream reach was not altered. 2. Decomposition rate, microbial respiration, fungal...

The Evolution of Increased Competitive Ability (EICA) hypothesis predicts that introduced plants should lose enemy resistance and in turn evolve increased size or fecundity. We tested the first prediction of this hypothesis by growing introduced North American and native European genotypes of St. John’s Wort (Hypericum perforatum) in common gardens in the state of Washington, USA, and in Girona...

Aquatic hyphomycetes occur worldwide on a wide range of plant substrates decomposing in freshwaters, and are known to play a key role in organic matter turnover. The presumed worldwide distribution of many aquatic hyphomycete species has been based on morphology-based taxonomy and identification, which may overlook cryptic species, and mask global-scale biogeographical patterns. This might be c...

During a study on fungal diversity in petroleum contaminated soils in Khuzestan province, two species of hyphomycetes were isolated, which represent new records for the mycobiota of Iran. Based on the combination of morphological data and ITS-rDNA sequence, the isolates were identified as Alternaria obovoidea and Emericellopsis pallida. Morphological descriptions and illustrations are provided ...

Black fungi are an ecological group of melanized specialized in extremotolerance and assumed to be among the most stress-resistant eukaryotes on Earth. Multi-omics studies have provided significant evidence that they a peculiar response stress differs considerably from common mesophilic hyphomycetes. Survival strategies displayed by these organisms situated them as attractive models for astrobi...
