High-Up: A Remote Reservoir of Microbial Extremophiles in Central Andean Wetlands [PDF]
, 2015 The Central Andes region displays unexplored ecosystems of shallow lakes and salt flats at mean altitudes of 3700 m. Being isolated and hostile, these so-called “High-Altitude Andean Lakes” (HAAL) are pristine and have been exposed to little human ...

Factors shaping community patterns of protists and bacteria on a European scale
Environmental Microbiology, Volume 22, Issue 6, Page 2243-2260, June 2020., 2020 Summary Factors shaping community patterns of microorganisms are controversially discussed. Physical and chemical factors certainly limit the survival of individual taxa and maintenance of diversity. In recent years, a contribution of geographic distance and dispersal barriers to distribution patterns of protists and bacteria has been demonstrated ...

How do microbiota associated with an invasive seaweed vary across scales?
Molecular Ecology, Volume 29, Issue 11, Page 2094-2108, June 2020., 2020 Abstract Communities are shaped by scale dependent processes. To study the diversity and variation of microbial communities across scales, the invasive and widespread seaweed Agarophyton vermiculophyllum presents a unique opportunity. We characterized pro‐ and eukaryotic communities associated with this holobiont across its known distribution range ...

Cyclotella alvarniensis (Stephanodiscaceae): ¿Diatomea moderna o fósil?
Anales del Jardín Botánico de Madrid, 2023 Cyclotella alvarniensis es considerada una especie fósil de diatomea del Mioceno Superior. La presencia de esta especie suele estar asociada a su proximidad a zonas de explotación de diatomita. Se han encontrado frústulas en algunas regiones de España (Murcia-Albacete), Francia, Suiza y recientemente en Senegal. Sin embargo, las causas de su dispersión

Expression of genes involved in phagocytosis in uncultured heterotrophic flagellates
Limnology and Oceanography, Volume 65, Issue S1, Page S149-S160, January 2020., 2020 Abstract Environmental molecular sequencing has revealed an abundance of microorganisms that were previously unknown, mainly because most had not been cultured in the laboratory. Within this novel diversity, there are the uncultured MAST clades (MArine STramenopiles), which are major components of marine heterotrophic flagellates (HFs) thought to be ...
