Overfishing and sea warming drive the collapse of Paracentrotus lividus. [PDF]

Sci Rep
Abstract As a seafood delicacy, the purple sea urchin Paracentrotus lividus is the most exploited echinoid species in the Mediterranean Sea, with a significant increase in total catches being reported over the last 2 decades. This work presents: (i) the findings from two demographic monitoring campaigns, conducted on P. lividus populations in

Habitat preferences of the sea urchin Paracentrotus lividus  [PDF]

Marine Ecology Progress Series, 2012
Population structure of the sea urchin Paracentrotus lividus seems to vary depending on the habitat, as, on average, urchin density is higher on rocks, and size is larger in Posidonia oceanica seagrass. Here, we tested the hypothesis that P. lividus would choose P.

Acute Toxicity of Perfluorooctane Sulfonic Acid on Early Life Stages of Daphnia Magna, Siriella Armata, Paracentrotus Lividus Sea Urchin, and Turbot (Scophthalmus Maximus L.). [PDF]

, 2010
Perfluorooctane sulfonate (PFOS) is a persistent organic pollutant whose potential toxicity is causing great concern. In the present study, we used two crustaceans (_Daphnia magna_, _Siriella armata_), echinoid embryos (_Paracentrotus lividus_) and ...

Functional traits of two co-occurring sea urchins across a barren/forest patch system [PDF]

, 2013
Temperate rocky reefs may occur in two alternative states (coralline barrens and erect algal forests), whose formation and maintenance are often determined by sea urchin grazing.

Recovery trends of commercial fish: the case of an underperforming Mediterranean marine protected area [PDF]

, 2016
Temporal trends in the recovery of exploited species in marine protected areas (MPAs) are useful for a proper assessment of the efficacy of protection measures.

Toxicity of diatom-derived polyunsaturated aldehyde mixtures on sea urchin Paracentrotus lividus development [PDF]

, 2019
Diatom-derived polyunsaturated aldehydes (PUAs), decadienal, heptadienal and octadienal, derive from the oxidation of fatty acids and have cytotoxic and anticancer effects. PUAs, tested separately, induce malformations in sea urchin Paracentrotus lividus

A wnt2 ortholog in the sea urchin Paracentrotus lividus [PDF]

genesis, 2019
SummaryMembers of the wnt gene family encode secreted glycoproteins that mediate critical intercellular communications in metazoans. Large‐scale genome and transcriptome analyses have shown that this family is composed of 13 distinct subfamilies. These analyses have further established that the number of wnt genes per subfamily varies significantly ...

Microsatellite markers reveal shallow genetic differentiation between cohorts of the common sea urchin Paracentrotus lividus (Lamarck) in northwest Mediterranean [PDF]

, 2009
Temporal variability was studied in the common sea urchin Paracentrotus lividus through the analysis of the genetic composition of three yearly cohorts sampled over two consecutive springs in a locality in northwestern Mediterranean.
