Annotated 18S and 28S rDNA reference sequences of taxa in the planktonic diatom family Chaetocerotaceae. [PDF]

PLoS ONE, 2018
The species-rich diatom family Chaetocerotaceae is common in the coastal marine phytoplankton worldwide where it is responsible for a substantial part of the primary production.

Pengaruh Cahaya Terhadap Produksi Fukosantin Chaetoceros calcitrans (Paulsen) Takano 1968 (Bacillariophyceae: Chaetocerotaceae)

Jurnal Kelautan Tropis, 2019
Fucoxanthin is a pigment of the carotenoid group that can be used in the food and human health. The demand for natural carotenoid in the global market is quite high for food nutrition, food colorant, medicine, and cosmetic.

Tropics to the Poles: A Snapshot of Coastal Eukaryotic Marine Microalgal Diversity Across Five Ecoregions. [PDF]

Mol Ecol
ABSTRACT Eukaryotic microalgae are key organisms in marine environments, contributing to essential nutrient and biogeochemical cycles. Climate change is already causing shifts in the composition and diversity of microalgal assemblages, with coastal ecosystems experiencing increased pressure.

A full-length 18S ribosomal DNA metabarcoding approach for determining protist community diversity using Nanopore sequencing. [PDF]

Ecol Evol
A new primer pair combination was used to amplify the full‐length 18S rDNA and its efficacy was validated with a test community. The full‐length sequences obtained with the Nanopore MinION for protist diversity from field samples yielded improved taxonomic resolution when compared with Illumina MiSeq V4 and V8‐V9 short reads. Abstract Protist diversity

A multigene phylogeny to infer the evolutionary history of Chaetocerotaceae (Bacillariophyta)

Molecular Phylogenetics and Evolution, 2019
The diatom family Chaetocerotaceae (Bacillariophyta) is common in the marine plankton worldwide, especially in coastal areas and upwelling zones. Its defining character constitutes hollow processes, called setae, which emerge from the valves of the vegetative cells. The family comprises two extant genera: Bacteriastrum and Chaetoceros.

Diversity, Distribution and Evolution of the Planktonic Diatom Family Chaetocerotaceae [PDF]

Estuarine, Coastal and Shelf Science, 2017
The number and abundance of diatom species in environmental samples are counted traditionally by means of light microscopy (LM). However, recognizing –let alone, counting- species is often challenging because of the existence of cryptic species and intraspecific phenotypic plasticity.

Evaluation of the nutritional quality of Chaetoceros muelleri Schütt (Chaetocerotales: Chaetocerotaceae) and Isochrysis sp. (Isochrysidales: isochrysidaceae) grown outdoors for the larval development of Litopenaeus vannamei (Boone, 1931) (Decapoda: Penaeidae) [PDF]

Archives of Biological Sciences, 2012
The biomass, proximal composition and fatty acid profile of Isochrysis sp., Chaetoceros muelleri and their mixture, grown under greenhouse conditions, were evaluated.

From metabarcoding time series to plankton food webs: The hidden role of trophic hierarchy in providing ecological resilience

Marine Ecology, Volume 44, Issue 3, June 2023., 2023
Abstract The advent of metabarcoding (metaB) in aquatic ecology has provided a huge amount of information on plankton biodiversity worldwide. However, the large datasets obtained with that approach are still partially explored, especially for what concerns the study of trophic interactions and food webs.

Nutrient limitation can explain a rapid transition to synchrony in an upwelling‐driven diatom community

Limnology and Oceanography, Volume 67, Issue S1, Page S298-S311, February 2022., 2022
Abstract Identifying the mechanisms controlling the temporal dynamics of ecological communities is key to understand their vulnerability to natural and anthropogenic impacts and to identify early warnings of critical transitions. At community level, inter‐specific synchrony is an important indicator of ecosystem stability and variation in function ...

Sedimentary Ancient DNA From the Subarctic North Pacific: How Sea Ice, Salinity, and Insolation Dynamics Have Shaped Diatom Composition and Richness Over the Past 20,000 Years

Paleoceanography and Paleoclimatology, Volume 36, Issue 4, April 2021., 2021
Abstract We traced diatom composition and diversity through time using diatom‐derived sedimentary ancient DNA (sedaDNA) from eastern continental slope sediments off Kamchatka (North Pacific) by applying a short, diatom‐specific marker on 63 samples in a DNA metabarcoding approach.
