Relative abundance and size composition of Red sea urchin, Strongylocentrotus franciscanus, populations along the Mendocino county coast, 1991 [PDF]

open access: yes, 1993
Underwater surveys were conducted in the summer of 1991, as part of a three year survey, to determine density and size composition of red sea urchin, Strongylocentrotus franciscanus, populations along the Mendocino coast at three different depth zones ...

Gene regulatory network subcircuit controlling a dynamic spatial pattern of signaling in the sea urchin embryo [PDF]

open access: yes, 2008
We dissect the transcriptional regulatory relationships coordinating the dynamic expression patterns of two signaling genes, wnt8 and delta, which are central to specification of the sea urchin embryo endomesoderm.

Titanium dioxide nanoparticles stimulate sea urchin immune cell phagocytic activity involving TLR/p38 MAPK-mediated signalling pathway

open access: yesScientific Reports, 2015
Titanium dioxide nanoparticles (TiO2NPs) are one of the most widespread-engineered particles in use for drug delivery, cosmetics and electronics. However, TiO2NP safety is still an open issue, even for ethical reasons.

Extent and toxicity of contaminated marine sediments in Southeastern Florida [PDF]

open access: yes, 2004
Thirty sites were sampled in southern Biscayne Bay and Manatee Bay in December 1999 to determine the extent of toxicity in sediments. Analyses and assays included: pesticides and phenols in seawater; chemical contaminants in sediment; amphipod mortality,

Flagellar propulsion [PDF]

open access: yes, 2006
In this JEB Classics paper, Sir James Gray and G. J. Hancock explained how spermatozoa are propelled by flagellar bending waves (Gray and Hancock, 1955). This paper was a lasting success because it provided an easy-to-understand solution to a complicated

Biobanking of a Marine Invertebrate Model Organism: The Sea Urchin

open access: yes, 2016
The sea urchin has long been used as an invertebrate model organism in developmental biology, membrane transport and sperm oocyte interactions, and for the assessment of marine pollution.

A management support framework for subtidal rockyreef communities on the east coast of Tasmania [PDF]

open access: yes, 2011
We developed a local and regional scale simulation model of the important dynamical features of seaweed-based rocky reef systems in eastern Tasmania.

A Rapid Colorimetric Method Reveals Fraudulent Substitutions in Sea Urchin Roe Marketed in Sardinia (Italy)

open access: yesFoods, 2016
In recent years, besides the consumption of fresh sea urchin specimens, the demand of minimally-processed roe has grown considerably. This product has made frequent consumption in restaurants possible and frauds are becoming widespread with the partial ...

Developmental gene regulatory network architecture across 500 million years of echinoderm evolution [PDF]

open access: yes, 2003
Evolutionary change in morphological features must depend on architectural reorganization of developmental gene regulatory networks (GRNs), just as true conservation of morphological features must imply retention of ancestral developmental GRN features ...

Autophagy as a defense strategy against stress: focus on Paracentrotus lividus sea urchin embryos exposed to cadmium

open access: yesCell stress & chaperones (Print), 2015
Autophagy is used by organisms as a defense strategy to face environmental stress. This mechanism has been described as one of the most important intracellular pathways responsible for the degradation and recycling of proteins and organelles.
