Prey preference in a kleptoplastic dinoflagellate is linked to photosynthetic performance
(Springer Nature, 2023-06-30)
Dinoflagellates of the family Kryptoperidiniaceae, known as “dinotoms”, possess diatom-derived endosymbionts and contain individuals at three successive evolutionary stages: a transiently maintained ...
Eileen J. Cox: her journey with diatoms
(National Botanic Garden of Belgium and Royal Botanical Society of Belgium, 2019-07-09)
Eileen already had a keen interest in science during her school years. She studied Botany at Bristol University from 1967–1970, and it was her University teacher, Professor Frank Round, who inspired her ...
Nitzschia fenestralis: A new diatom species abundant in the Holocene sediments of an eastern African crater lake
(Czech Phycological Society, 2020-02-18)
Nitzschia is common in the phytoplankton of several East African lakes. A new species, Nitzschia fenestralis, sp. nov. D. Grady, D.G. Mann et Trobajo was encountered at numerous depths in a 16 m sediment ...
Discovery of a kleptoplastic 'dinotom' dinoflagellate and the unique nuclear dynamics of converting kleptoplastids to permanent plastids
(Nature Research, 2019-07-19)
A monophyletic group of dinoflagellates, called ‘dinotoms’, are known to possess evolutionarily intermediate plastids derived from diatoms. The diatoms maintain their nuclei, mitochondria, and the ...
Diatoms as dandelions: convergent evolution in the reproductive biology of small Nitzschia species (Bacillariophyta) and its possible taxonomic consequences
(Taylor & Francis Group, 2024-03-01)
Nitzschia soratensis and N. inconspicua are two small diatoms that are extremely similar in the light microscope though separable in subtle aspects of valve and girdle ultrastructure. They are not closely ...
Evaluation and sensitivity analysis of diatom DNA metabarcoding for WFD bioassessment of Mediterranean rivers
(Elsevier, 2020-04-04)
Our study of 164 diatom samples from Catalonia (NE Spain) is the first to evaluate the applicability of DNA metabarcoding, based on high throughput sequencing (HTS) using a 312-bp rbcL marker, for ...
Description of Navicula vanseea sp. nov. (Naviculales, Naviculaceae), a new species of diatom from the highly alkaline Lake Van (Republic of Türkiye) with complete characterisation of its organellar genomes and multigene phylogeny
(Pensoft Publishers, 2024-04-08)
The current article describes Navicula vanseea sp. nov., a new species of diatom from Lake Van, a highly alkaline lake in Eastern Anatolia (Türkiye). The description is based on light and scanning ...
Taxonomy and diversity of a little-known diatom genus Simonsenia (Bacillariaceae) in the marine littoral: novel taxa from the Yellow Sea and the Gulf of Mexico
(National Botanic Garden of Belgium and Royal Botanical Society of Belgium, 2019-07-09)
Background and aims – The diatom genus Simonsenia has been considered for some time a minor taxon, limited in its distribution to fresh and slightly brackish waters. Recently, knowledge of its diversity ...
A rapid cleaning method for diatoms
(Taylor & Francis, 2019-07-18)
We describe here a protocol for cleaning diatoms when time is short and the amount of
sample is very limited. Essentially, the method consists of drying material onto coverslips and
cleaning it directly ...
The future of biotic indices in the ecogenomic era: Integrating (e)DNA metabarcoding in biological assessment of aquatic ecosystems
(Elsevier, 2018-05-22)
The bioassessment of aquatic ecosystems is currently based on various biotic indices that use the occurrence and/or abundance of selected taxonomic groups to define ecological status. These conventional ...
