Collateral effects of microplastic pollution on aquatic microorganisms: An ecological perspective 

Arias Andrés, María de Jesús; Rojas Jiménez, Keilor Osvaldo; Grossart, Hans-Peter (2018-12-05)
Microplastics (MP) provide a unique and extensive surface for microbial colonization in aquatic ecosystems. The formation of microorganism-microplastic complexes, such as biofilms, maximizes the degradation of organic ...

The contrasting roles of aquatic fungi and oomycetes in the degradation and transformation of polymeric organic matter 

Masigol, Hossein; Khodaparast, Seyed Akbar; Woodhouse, Jason Nicholas; Rojas Jiménez, Keilor Osvaldo; Fonvielle, Jeremy; Rezakhani, Forough; Mostowfizadeh Ghalamfarsa, Reza; Neubauer, Darshan; Goldhammer, Tobias; Grossart, Hans-Peter (2019)
Studies on the ecological role of fungi and, to a lesser extent, oomycetes, are receiving increasing attention, mainly due to their participation in the cycling of organic matter in aquatic ecosystems. To unravel their ...

A Salinity Threshold Separating Fungal Communities in the Baltic Sea 

Rojas Jiménez, Keilor Osvaldo; Rieck, Angelika; Wurzbacher, Christian; Jürgens, Klaus; Labrenz, Matthias; Grossart, Hans-Peter (2019)
Salinity is a significant factor for structuring microbial communities, but little is known for aquatic fungi, particularly in the pelagic zone of brackish ecosystems. In this study, we explored the diversity and composition ...

Notes on Dictyuchus species (Stramenopila, Oomycetes) from Anzali lagoon, Iran 

Masigol, Hossein; Khodaparast, Seyed Akbar; Mostowfizadeh Ghalamfarsa, Reza; Mousanejad, Sedigheh; Rojas Jiménez, Keilor Osvaldo; Grossart, Hans-Peter (2018)
Nine Dictyuchus isolates were obtained from floating and decaying twigs and leaves in Anzali lagoon, Anzali County, Guilan province, Iran. They are interestingly distinguished from current Dictyuchus species by the presence ...

Early diverging lineages within Cryptomycota and Chytridiomycota dominate the fungal communities in ice-covered lakes of the McMurdo Dry Valleys, Antarctica 

Rojas Jiménez, Keilor Osvaldo; Wurzbacher, Christian; Bourne, Elizabeth Charlotte; Chiuchiolo, Amy; Priscu, John C.; Grossart, Hans-Peter (2017-11)
Antarctic ice-covered lakes are exceptional sites for studying the ecology of aquatic fungi under conditions of minimal human disturbance. In this study, we explored the diversity and community composition of fungi in five ...

A New Parasitic Chytrid, Staurastromyces oculus (Rhizophydiales, Staurastromycetaceae fam. nov.), Infecting the Freshwater Desmid Staurastrum sp. 

Wyngaert, Silke Van den; Seto, Kensuke; Rojas Jiménez, Keilor Osvaldo; Kagami, Maiko; Grossart, Hans-Peter (2017-08)
Chytrids are a diverse group of ubiquitous true zoosporic fungi. The recent molecular discovery of a large diversity of undescribed chytrids has raised awareness on their important, but so far understudied ecological role ...

Microplastics alter composition of fungal communities in aquatic ecosystems 

Kettner, Marie Therese; Rojas Jiménez, Keilor Osvaldo; Oberbeckmann, Sonja; Labrenz, Matthias; Grossart, Hans-Peter (2017)
Despite increasing concerns about microplastic (MP) pollution in aquatic ecosystems, there is insufficient knowledge on how MP affect fungal communities. In this study, we explored the diversity and community composition ...

Transformation of humic substances by the freshwater Ascomycete Cladosporium sp. 

Rojas Jiménez, Keilor Osvaldo; Fonvielle, Jeremy; Ma, Hua; Grossart, Hans-Peter (2017)
The ecological relevance of fungi in freshwater ecosystems is becoming increasingly evident, particularly in processing the extensive amounts of polymeric organic carbon such as cellulose, chitin, and humic substances (HS). ...

Aquatic fungi: targeting the forgotten in microbial ecology 

Grossart, Hans-Peter; Rojas Jiménez, Keilor Osvaldo (2016-06)
Fungi constitute important and conspicuous components of aquatic microbial communities, but their diversity and functional roles remain poorly characterized. New methods and conceptual frameworks are required to accurately ...

Fungi in aquatic ecosystems 

Grossart, Hans-Peter; Wyngaert, Silke Van den; Kagami, Maiko; Wurzbacher, Christian; Cunliffe, Michael; Rojas Jiménez, Keilor Osvaldo (2019-03)
Fungi are phylogenetically and functionally diverse ubiquitous components of almost all ecosystems on Earth, including aquatic environments stretching from high montane lakes down to the deep ocean. Aquatic ecosystems, ...
