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

Duarte, Sofia; Seena, Sahadevan; Bärlocher, Felix; Pascoal, Cláudia; Cássio, Fernanda

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...


Temperature alters interspecific relationships among aquatic fungi

Duarte, Sofia; Fernandes, Isabel Rodrigues; Nogueira, Maria João; Cássio, Fernanda; Pascoal, Cláudia

This is not the final version of the paper ; Temperature is a key factor in determining the structure and performance of fungal assemblages on decomposing plant litter in streams. However, little is known of how temperature affects interspecific relationships among fungi. We compared the growth of four aquatic hyphomycetes co-occurring in temperate streams, in monocultures and all species combinations when exp...

This version does not correspond to the published one. To access the final version go to: http://www.springerlink.com/content/a31518u452m03286/ ; In aquatic ecosystems, microorganisms and invertebrates provide critical links between plant detritus and higher trophic levels. Atyaephyra desmarestii is an omnivorous decapod that inhabits freshwaters and exhibits high tolerance to temperature oscillations and high...


Preliminary insights into the phylogeography of six aquatic Hyphomycete Species

Duarte, Sofia; Seena, Sahadevan; Bärlocher, Felix; Cássio, Fernanda; Pascoal, Cláudia

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...

Effects of increased temperature and aquatic fungal diversity on litter decompo...

Geraldes, Paulo; Pascoal, Cláudia; Cássio, Fernanda

This version thus not correspond to the final version of the journal. To assess the final version please go to: http://www.sciencedirect.com/science/article/pii/S1754504812000876 ; Climate warming and biodiversity loss are two major factors threatening freshwaters. Aquatic hyphomycetes are fungi that play a key role in organic matter turnover in streams. To assess the impacts of temperature increase and aquati...


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

Seena, Sahadevan; Duarte, Sofia; Pascoal, Cláudia; Cássio, Fernanda

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...
