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 ...

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 ...

Dry-season leaf flushing of Enterolobium cyclocarpum (ear-pod tree): above- and belowground phenology and water relations 

Rojas Jiménez, Keilor Osvaldo; Holbrook, Noel Michele; Gutiérrez Soto, Marco Vinicio (2007-11)
Above- and belowground phenology and water relations of Enterolobium cyclocarpum Jacq. trees in the dry forest of Santa Rosa National Park, Costa Rica were studied during two consecutive phenological cycles, from November ...

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 ...

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 ...

Isolation of Fungi and Bacteria Associated with the Guts of Tropical Wood-Feeding Coleoptera and Determination of Their Lignocellulolytic Activities 

Rojas Jiménez, Keilor Osvaldo; Hernández Alfaro, Myriam (2015-08)
The guts of beetle larvae constitute a complex system where relationships among fungi, bacteria, and the insect host occur. In this study, we collected larvae of five families of wood-feeding Coleoptera in tropical forests ...

Relaciones hídricas en árboles del bosque tropical seco: el caso de Enterolobium cyclocarpum 

Rojas Jiménez, Keilor Osvaldo; Gutiérrez Soto, Marco Vinicio (2011)
Las relaciones hídricas en árboles de Enterolobium cyclocarpum del Parque Nacional Santa Rosa, Costa Rica, se estudiaron en diferentes momentos del curso diurno y a lo largo de dos ciclos fenológicos. La característica ...

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 ...

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 ...
