Evidence for association of Vibrio echinoideorum with tissue necrosis on test of the green sea urchin Strongylocentrotus droebachiensis

open access: yesScientific Reports, 2022
“Sea urchin lesion syndrome” is known as sea urchin disease with the progressive development of necrotic epidermal tissue and loss of external organs, including appendages on the outer body surface. Recently, a novel strain, Vibrio echinoideorum has been

Grazing in the dark: A behavioural adjustment in a population of the black sea urchin Arbacia lixula

open access: yesEcology and Evolution, 2023
In Mediterranean rocky shores, the black sea urchin Arbacia lixula is often associated with communities dominated by encrusting corallines, devoid of fleshy algae.

Sea Urchin-Inspired Immuno-Instructive Ionic Flow Drives MSCs-Macrophage Communication to Promote Bone Regeneration. [PDF]

open access: yesAdv Mater
ABSTRACT Bone tissue regeneration is a complex physiological process dependent on the spatiotemporal coordination of immune cells and stem cells. Conventional research primarily elucidates the mechanism through which materials facilitate bone formation by initially modulating macrophages and subsequently encouraging the osteogenic differentiation of ...

Seagrass abundance and morphological, nutritional and biochemical traits in relation to sea urchin Tripneustes gratilla overgrazing

open access: yes, 2022
We studied the grazing of tropical seagrass species by the sea urchin Tripnesutes gratilla in relation to seagrass traits and abundance. The inception of this project happened after witnessing the overgrazing of the seagrass species Thalassodendron ...

The challenge of managing the commercial harvesting of the sea urchin Paracentrotus lividus: advanced approaches are required [PDF]

open access: yesPeerJ, 2020
Sea urchins act as a keystone herbivore in marine coastal ecosystems, regulating macrophyte density, which offers refuge for multiple species. In the Mediterranean Sea, both the sea urchin Paracentrotus lividus and fish preying on it are highly valuable ...

Uncommon southwest swells trigger sea urchin disease outbreaks in Eastern Atlantic archipelagos

open access: yesEcology and Evolution, 2020
Recurrent sea urchin mass mortality has recently affected eastern Atlantic populations of the barren‐forming sea urchin Diadema africanum. This new episode of die‐off affords the opportunity to determine common meteorological and oceanographic conditions

The sea urchin's siren

open access: yesDevelopmental Biology, 2006
This issue of Developmental Biology features articles that constitute a new wave of insights into how a genome interacts with itself (as DNA) and with effectors-proteins and probably RNAs, collectively operating as a kind of "cis-trans" dualism. We learned a test for allelism in genetics class that bore that Latin name but now it comes as a new day for

On artificial parthenogenesis in sea-urchins. [PDF]

open access: yesScience, 1900
IN No. 277 of SCIENCE, I stated that the MgCl 2 solution used in my experiments on artificial parthenogenesis was a 20/8 n solution. I have since found that the assistant who made the Mg-solution used and who has left the laboratory must have made a mistake as the solution contained only ...

Characterization of sea-urchin fibronectin [PDF]

open access: yesBiochemical Journal, 1983
Sea-urchin fibronectin from the ovary of the sea urchin Pseudocentrotus depressus bound to gelatin, fibrin and fibrinogen. After mild digestion of the protein labelled with 125I, a 195 000 Da domain was observed. Sea-urchin fibronectin was aggregated by spermine (1 mM) at neutral pH.
