A decade's perspective on the impact of DNA sequencing on aquatic hyphomycete r...

This is not the final version of the paper ; A decade has passed since the first DNA sequences of aquatic hyphomycete species have become available. They have illuminated aspects of their phylogeny and evolution that were inaccessible by conventional methods. Here we present examples of how the resulting information has modified our knowledge of aquatic hyphomycetes. Generating more and better DNA sequence dat...

Preliminary insights into the phylogeography of six aquatic Hyphomycete Species

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 circumvented by us...

Preliminary Insights into the phylogeography of six aquatic hyphomycete species

Intraspecific variation of the aquatic fungus articulospora tetracladia : an ub...

The worldwide-distributed aquatic fungus Articulospora tetracladia Ingold is a dominant sporulating species in streams of the Northwest Iberian Peninsula. To elucidate the genetic diversity of A. tetracladia, we analyzed isolates collected from various types of plant litter or foam in streams from North and Central Portugal and North Spain, between 2000 and 2010. Genetic diversity of these fungal populations wa...

Effects of nano CuO on aquatic decomposers : from community to cellular responses

Can metal nanoparticles be a threat to microbial decomposers of plant litter in...

The extensive use of nanometal-based products increases the chance of their release into aquatic environments, raising the question whether they can pose a risk to aquatic biota and the associated ecological processes. Aquatic microbes, namely fungi and bacteria, play a key role in forested streams by decomposing plant litter from terrestrial vegetation. Here, we investigated the effects of nanocopper oxide and...
