Diversity and hidden host specificity of chytrids infecting colonial volvocacean algae 

Wyngaert, Silke Van den; Rojas Jiménez, Keilor Osvaldo; Seto, Kensuke; Kagami, Maiko; Grossart, Hans-Peter (2018-05)
Chytrids are zoosporic fungi that play an important, but yet understudied, ecological role in aquatic ecosystems. Many chytrid species have been morphologically described as parasites on phytoplankton. However, the majority ...

A preliminary report of aquatic hyphomycetes isolated from Anzali lagoon (Gilan province, North of Iran)
* گزارش مقدماتی از هیفومیستهاي آبزي تالاب انزلی (استان گیلان) 

Rezakhani, Forough; Khodaparast, Seyed Akbar; Masigol, Hossein; Rojas Jiménez, Keilor Osvaldo; Grossart, Hans-Peter; Bakhshi, Mounes (2019)
Aquatic hyphomycetes equipped with a rich array of extracellular enzymes are involved in bioremediation of anthropogenic pollutants, plastics, aromatic contaminants and petroleum hydrocarbons. The current study contributes ...

Microorganismos del corredor marino Isla del Coco-Galápagos: diversidad funcional y de especies 

Rojas Jiménez, Keilor Osvaldo (2018)
El corredor marino Isla del Coco-Galápagos, en su conjunto, constituye un santuario para la protección de especies marinas en la región oriental del Pacífico Tropical. La alta biodiversidad de macroorganismos ha sido ...

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 ...

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 ...

Microplastic ingestion by a herring Opisthonema sp. in the Pacific coast of Costa Rica 

Bermúdez Guzmán, Luis; Alpízar Villalobos, Crista; Gatgens García, Johan; Jiménez Huezo, Gabriel; Rodríguez Arias, Marco; Molina Ureña, Helena; Villalobos Porras, Javier; Paniagua Pérez, Sergio; Vega Baudrit, José Roberto; Rojas Jiménez, Keilor Osvaldo (2020-07)
Current knowledge of the presence of microplastics (MP) in marine species in tropical areas is still limited. The presence of MP was examined in the gastrointestinal content of 30 filter feeders of the herring Opisthonema ...

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, ...

Richness of cultivable endophytic fungi along an altitudinal gradient in wet forests of Costa Rica 

Rojas Jiménez, Keilor Osvaldo; Hernández Alfaro, Myriam; Blanco Salas, Jorge; Vargas, Luis Diego; Acosta Vargas, Luis Guillermo; Tamayo Castillo, Giselle (2016-04)
We collected various plant species along an altitudinal gradient ranging from 400 to 2900 m in tropical wet forests of Costa Rica, isolated the associated endophytic fungi, and performed bioinformatic analyses to determine ...

Study of the diversity of culturable actinomycetes in the North Pacific and Caribbean coasts of Costa Rica 

Solano Arias, Godofredo; Rojas Jiménez, Keilor Osvaldo; Jaspars, Marcel; Tamayo Castillo, Giselle (2009)
In this study, 137 actinomycetes were isolated from subtidal marine sediments in the North Pacific and Caribbean coasts of Costa Rica. Bioinformatics analysis of the 16S rRNA gene sequences assigned the isolates to 15 ...
