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 ...

Coscinodiscophyceae and Fragilariophyceae (Diatomeae) in the Iguaçu River, Paraná, Brazil [PDF]

Acta Botanica Brasilica, 2014
A taxonomic survey was carried out on Coscinodiscophyceae and Fragilariophyceae found in the Iguaçu River catchment area within Iguaçu National Park, in the state of Paraná, Brazil. Between September 2007 and August 2008, we collected 24 samples from two stations on the Iguaçu River, upstream and downstream of the falls.

Control of Bovicola equi infestation in a herd of horses using an environmentally sustainable treatment protocol

Veterinary Record Case Reports, Volume 14, Issue 1, February 2026.
Abstract In March 2024, a Slovenian warmblood gelding presented with severe pruritus and skin lesions throughout its head, neck and around the base of the tail. The owners had observed increased pruritus in multiple animals within the herd. After careful examination, Bovicola equi were found in all five horses, but not the pony.

Environmental Factors, Not Biotic Competitive Interactions, Drive the Relative Abundance of Diatoms and Chlorophyta in the Coastal Areas of the Beibu Gulf: Evidence From 18S rDNA Metabarcoding and Partial Least Squares‐Path Modeling Analysis

Ecology and Evolution, Volume 15, Issue 8, August 2025.
Using high‐throughput sequencing (HTS) analysis, a negative correlation was found between Bacillariophyta and Chlorophyta near the Dafeng River Estuary (DRE) and the Sanniang Bay (SNB) located in the Beibu Gulf, China. The partial least squares‐path modeling (PLS‐PM) analysis showed that both the differing responses of Chlorophyta and Bacillariophyta ...
