An ubiquitous perspective of the intraspecific diversity of the aquatic fungus ...
Seena, Sahadevan; Duarte, Sofia Alexandra Ferreira; Pascoal, Cláudia; Cássio, FernandaThe cosmopolitan Articulospora tetracladia is a dominant sporulating species on decomposing plant-litter in streams of Northwest Iberian Peninsula. In an attempt to elucidate the intraspecific genetic diversity of A. tetracladia of Iberian Peninsula, isolates were attained from various types of substrates from streams of North and Central Portugal and North Spain, between 2000 and 2010. Genetic diversity of the...
Preliminary insights into the phylogeography of six aquatic Hyphomycete Species
Duarte, Sofia Alexandra Ferreira; Seena, Sahadevan; Bärlocher, Felix; Cássio, Fernanda; Pascoal, CláudiaAquatic 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...

Seena, Sahadevan; Duarte, Sofia Alexandra Ferreira; Pascoal, Cláudia; Cássio, FernandaThe 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...

Microscopy- or DNA-based analyses: Which methodology gives a truer picture of s...
Fernandes, Isabel Rodrigues; Pereira, Ana; Trabulo, José; Pascoal, Cláudia; Cássio, Fernanda; Duarte, Sofia Alexandra FerreiraWe assessed aquatic hyphomycete diversity in autumn and spring on oak leaves decomposing in five streams along a gradient of eutrophication in the Northwest of Portugal. Diversity was assessed through microscopy-based (identification by spore morphology) and DNA-based techniques (Denaturing Gradient Gel Electrophoresis and 454 pyrosequencing). Pyrosequencing revealed five times greater diversity than DGGE. Abou...
Seasonal Variability May Affect Microbial Decomposers and Leaf Decomposition Mo...
Duarte, Sofia Alexandra Ferreira; Cássio, Fernanda; Ferreira, Verónica; Canhoto, Cristina; Pascoal, CláudiaOngoing climate change is expected to affect the diversity and activity of aquatic microbes, which play a key role in plant litter decomposition in forest streams. We used a before-after control-impact (BACI) design to study the effects of warming on a forest stream reach. The stream reach was divided by a longitudinal barrier, and during 1 year (ambient year) both stream halves were at ambient temperature, whi...
