A cell-based boundary model of gastrulation by unipolar ingression in the hydrozoan cnidarian Clytia hemisphaerica

open access: yesDevelopmental Biology, 2020
In Cnidaria, modes of gastrulation to produce the two body layers vary greatly between species. In the hydrozoan species Clytia hemisphaerica gastrulation involves unipolar ingression of presumptive endoderm cells from an oral domain of the blastula, followed by migration of these cells to fill the blastocoel with concomitant narrowing of the gastrula ...

Two oppositely localised frizzled RNAs as axis determinants in a cnidarian embryo.

open access: yesPLoS Biology, 2007
In phylogenetically diverse animals, including the basally diverging cnidarians, "determinants" localised within the egg are responsible for directing development of the embryonic body plan. Many such determinants are known to regulate the Wnt signalling

A Widely Applicable Urea-based Fluorescent/Colorimetric mRNA in situ Hybridization Protocol

open access: yesBio-Protocol, 2019
In situ hybridization methods are routinely employed to detect nucleic acid sequences, allowing to localize gene expression or to study chromosomal organization in their native context. These methods rely on the pairwise binding of a labeled probe to the

High‐Resolution Longitudinal eDNA Metabarcoding and Morphological Tracking of Planktonic Threats to Salmon Aquaculture

open access: yesEnvironmental DNA, Volume 6, Issue 5, September–October 2024.
In the current study, we present and assess an exhaustive approach to identify the planktonic drivers of farmed Atlantic salmon complex gill disease (CGD) and fish mortality. We explored delayed or “lagged” effects of plankton abundances on gill health and undertook a comparison of environmental DNA (eDNA) metabarcoding and microscopy in their ability ...

Diversity and function of fluorescent molecules in marine animals

open access: yesBiological Reviews, Volume 99, Issue 4, Page 1391-1410, August 2024.
ABSTRACT Fluorescence in marine animals has mainly been studied in Cnidaria but is found in many different phyla such as Annelida, Crustacea, Mollusca, and Chordata. While many fluorescent proteins and molecules have been identified, very little information is available about the biological functions of fluorescence.

Environmental DNA for monitoring the impact of offshore wind farms on fish and invertebrate community structures

open access: yesEnvironmental DNA, Volume 6, Issue 4, July–August 2024.
Offshore windfarms are marine areas that are difficult to access, and innovative monitoring techniques are needed to study their impact on marine biodiversity. Water sampling and trawl catches conducted in parallel in 30 sites in the Belgian part of the North Sea showed that 12S eDNA metabarcoding retrieved 85.7% of the fish species caught in the beam ...

Mapping Cell Atlases at the Single‐Cell Level

open access: yesAdvanced Science, Volume 11, Issue 8, February 23, 2024.
The review discusses the technical characteristics of emerging single‐cell omics technologies and their diverse applications in various biological contexts, ranging from whole‐organism and single‐tissue analyses to studies involving evolution, development, aging, and diseases.

Large-scale deorphanization of Nematostella vectensis neuropeptide G protein-coupled receptors supports the independent expansion of bilaterian and cnidarian peptidergic systems

open access: yeseLife
Neuropeptides are ancient signaling molecules in animals but only few peptide receptors are known outside bilaterians. Cnidarians possess a large number of G protein-coupled receptors (GPCRs) – the most common receptors of bilaterian neuropeptides – but ...

Shallow-water Campanulariidae (Hydrozoa, Leptothecatae) from Northern Bahía, Brazil

open access: yesRevista de Biología Tropical, 2003
This study provides the first semi-quantititative account of the benthic campanulariid hydroids from Northern Bahia (Brazil), down to a depth of 60 m, based largely on collections obtained since 1992.
