Microbial Distortion? Impacts of Delayed Preservation on Microbiome Diversity and Composition in a Marine Invertebrate

MicrobiologyOpen, Volume 14, Issue 2, April 2025.
Delayed preservation of marine invertebrates during field sampling may impact microbiome characterization. Here, we show that a 3‐h preservation delay decreased microbiome richness in the ascidian Trididemnum solidum; however, menthol addition mitigated diversity loss and overall microbiome composition was not significantly altered, as dominant taxa ...

Ca2+ current in myotome cells of the lancelet (Branchiostoma lanceolatum).

The Journal of Physiology, 1992
1. By using the whole‐cell patch clamp method Ca2+ and Ba2+ currents were measured in the extremely thin twitch muscle cells of the protochordate Branchiostoma lanceolatum whose Ca2+ channels are likely to resemble the evolutionary ancestors of those found in vertebrate skeletal muscle. 2. When using 10 mM‐Ca2+ in the artificial external solution and 1

Morphological Stasis and Proteome Innovation in Cephalochordates [PDF]

, 2018
Lancelets, extant representatives of basal chordates, are prototypic examples of evolutionary stasis; they preserved a morphology and body-plan most similar to the fossil chordates from the early Cambrian.

XV. On the Anatomy of Amphioxus lanceolatus; Lancelet, Yarrell [PDF]

Transactions of the Royal Society of Edinburgh
The genus Amphioxus was instituted by Mr Yarrell for the reception of a singular little animal which he received from Mr Couch. The characters of this genus, as given in the History of British Fishes, are, “Body compressed, the surface without scales, both ends pointed; a single dorsal fin extending the whole length of the back; no pectoral, ventral ...

Marine fauna of Mljet National Park (Adriatic Sea, Croatia). 6. Leptocardia [PDF]

, 2016
Kopljača Branchiostoma lanceolatum Pallas, 1778, jedini je naš predstavnik razreda Leptocardia. Nalazimo je u svim morima Europe, pa tako i kod nas. Najčešća je u sjevernom Jadranu, a drugdje njezina su naselja vrlo ograničena. Našim je nalazima utvrđeno

The opsin repertoire of the European lancelet: a window into light detection in a basal chordate

The International Journal of Developmental Biology, 2017
Light detection in animals is predominantly based on the photopigment composed of a protein moiety, the opsin, and the chromophore retinal. Animal opsins originated very early in metazoan evolution from within the G-Protein Coupled Receptor (GPCR) gene superfamily and diversified into several distinct branches prior to the cnidarian-bilaterian split ...

New records of the lancelet Branchiostoma lanceolatum in Scottish waters

The Glasgow Naturalist, 2019
New records of the lancelet Branchiostoma lanceolatum from Scottish waters are presented. Most of the records originate from sublittoral monitoring around fish farms from Orkney, Shetland, the Western Isles, the Isles of Skye and Mull, but also from a distillery discharge in the Firth of Clyde and a plankton survey in the Sea of the Hebrides. Lancelets

Molecole coinvolte nella regolazione ionica in due specie di anfiosso provenienti da mari diversi

, 2016
. Abstract Molecules involved in ionic regulation in two species of lancelets from different seas. The presence of two molecules involved in osmoregulation and pH control (NHE and NKA) was demonstrated by immunocytochemical studies in Branchiostoma ...
