INDICE BIBLIOGRAFICO DE LAS DIATOMEAS (BACILLARIOPHYCEAE) DE CHILE

, 2020
Recientes revisiones de familias y géneros de diatomeas chilenas demuestran que el conocimiento taxonómico sobre esta flora es aún muy incompleto y, en muchas ocasiones, erróneo.

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

Diatomeas del registro sedimentario del sistema lagunar Yahuarcaca, Amazonas, Colombia

Revista de la Academia Colombiana de Ciencias Exactas, Físicas y Naturales
Los estudios sobre diatomeas en la Amazonia son relativamente escasos, a pesar del interés por la gran diversidad de esta región. El análisis taxonómico de diatomeas amazónicas amplía la comprensión de la diversidad de los ecosistemas acuáticos y ...

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 ...

ParAquaSeq, a Database of Ecologically Annotated rRNA Sequences Covering Zoosporic Parasites Infecting Aquatic Primary Producers in Natural and Industrial Systems

Molecular Ecology Resources, Volume 25, Issue 6, August 2025.
ABSTRACT Amplicon sequencing tools such as metabarcoding are commonly used for thorough characterisation of microbial diversity in natural samples. They mostly rely on the amplification of conserved universal markers, mainly ribosomal genes, allowing the taxonomic assignment of barcodes.

Colonización de diatomeas epizóicas sobre larvas de Aliger gigas (Mollusca: Gastropoda): Colonización de diatomeas epizóicas sobre larvas Aliger gigas

, 2022
Background. In Mexico, few studies have been carried out on epibiosis. Epizoic diatoms are used as biological indicators of ecosystems due to their apparent epibiont specificity with host animals.

A Scavenging Behavior of Cyclammina cancellata (Foraminifera, Rhizaria) on a Crustacean Carcass: Amino Acid Nitrogen Isotope and Microbiome Analyses

Marine Ecology, Volume 46, Issue 3, May/June 2025.
ABSTRACT Cyclammina cancellata is a common benthic foraminifer found at bathyal depths across the world's oceans. Despite its important role in deep‐sea food webs and biogeochemical cycles, the feeding habits of this species remain poorly understood. In this study, we document an aggregation of C.
