A revised classification of Cryptophyta [PDF]

Botanical Journal of the Linnean Society, 1999
Abstract The systematics of currently recognized cryptomonad genera is reviewed. Complete ultraIstructural descriptions are provided for each genus, and are based on the most recent observations in the literature. Using ultrastructural, biochemical and molecular data, a classification scheme, which delineates 16 genera, is proposed for the ...

HiMBar: A High-Fidelity Metagenomic Barcoding Approach for Transkingdom Species Detection and Interaction Analysis in Aquatic Ecosystems. [PDF]

Mol Ecol Resour
ABSTRACT Aquatic ecosystems host diverse organisms across all six life kingdoms, yet their complex interactions remain poorly understood, primarily due to limitations in transkingdom species detection methods. To address this limitation, we developed HiMBar (https://github.com/Xchenkai2019/HIFI_barcoding), a high‐fidelity (HiFi) metagenomic barcoding ...

Sustained Heatwaves Reshape the Phytoplankton-Zooplankton Community Structure in Freshwater Ecosystems: A Case Study of Shengjin Lake. [PDF]

Ecol Evol
The sustained heatwave has shaped the plankton community structure and led to high‐temperature domestication of some of the plankton. Plankton communities have the ability to resist heatwave stress. The sustained heatwave has altered the interrelationships between plankton.

Comparative Decay Dynamics and Detectability of eDNA and eRNA in Connected and Isolated Freshwater Mesocosms Using Digital PCR. [PDF]

Mol Ecol Resour
ABSTRACT Efficient use of environmental nucleic acids (eNAs) in freshwater biodiversity monitoring requires understanding their degradation and detectability in interconnected ecosystems. We employed a novel field‐scale assay to compare environmental DNA (eDNA) and environmental RNA (eRNA) decay rates and detectability across four genetic markers (16S,

Cryptophyta as major bacterivores in freshwater summer plankton [PDF]

The ISME Journal, 2018
Abstract Small bacterivorous eukaryotes play a cardinal role in aquatic food webs and their taxonomic classification is currently a hot topic in aquatic microbial ecology. Despite increasing interest in their diversity, core questions regarding predator–prey specificity remain largely unanswered, e.g., which heterotrophic nanoflagellates

Exploring the Regional Diversity of Eukaryotic Phytoplankton in the English Channel by Combining High-Throughput Approaches. [PDF]

Microbiologyopen
By combining flow cytometry and high‐throughput sequencing, we reveal seasonal and spatial variations in the size, composition, and diversity of phytoplankton in the English Channel, highlighting the dynamics of pico‐, nano‐, and microphytoplankton and environmental factors, with the Seine Bay as a hotspot of taxonomic and functional diversity ...

Flora algal de la cuenca del río Guadalquivir: Su valor en la determinación de la ecorregionalización de la cuenca [PDF]

, 2018
In compliance with the Water Framework Directive of the European Union, we needed to diagnose the ecologic quality of the different sections of the rivers of the Guadalquivir basin. In order to establish a regional classification of the water bodies by a

Fast preparative isoelectric focusing of phycocyanin subunits in layers of granulated gels [PDF]

, 1987
A new method is presented for the fast preparative separation of the light-harvesting photosynthetic pigment C-phycocanin into its and subunits, which is based on isoelectric focusing in layers of granutaled gels containing 7 M urea. The method has been
