Sea Urchin Removal as a Tool for Macroalgal Restoration: A Review on Removing “the Spiny Enemies”
Frontiers in Marine Science, 2022 Kelp and macroalgal forests provide the ecological foundations of many temperate rocky reef ecosystems, but have regionally declined, often due to sea urchin overgrazing and the formation of urchin barrens.

A Hermaphrodite Sea-Urchin [PDF]
Nature, 1932 COMPARATIVELY few cases of hermaphroditism have been recorded among echinoids. Gadd1 has described a specimen of Strongylocentrotus drbachiensis with four segments of the gonad female and one segment male. Gray2 has described a specimen of S. lividus with three segments female and two mixed female and male.

The evolutionary modifications of a GoLoco motif in the AGS protein facilitate micromere formation in the sea urchin embryo [PDF]
eLifeThe evolutionary introduction of asymmetric cell division (ACD) into the developmental program facilitates the formation of a new cell type, contributing to developmental diversity and, eventually, species diversification. The micromere of the sea urchin

The influence of physical factors on kelp and sea urchin distribution in previously and still grazed areas in the NE Atlantic. [PDF]
PLoS ONE, 2014 The spatial distribution of kelp (Laminaria hyperborea) and sea urchins (Strongylocentrotus droebachiensis) in the NE Atlantic are highly related to physical factors and to temporal changes in temperature. On a large scale, we identified borders for kelp

Between Life and Death: Sea Urchin Embryos Undergo Peculiar DNA Fragmentation after Exposure to Vanadium, Cadmium, Gadolinium, and Selenium [PDF]
LifeExogenous DNA damage represents one of the most harmful outcomes produced by environmental, physical, or chemical agents. Here, a comparative analysis of DNA fragmentation was carried out on Paracentrotus lividus sea urchin embryos exposed to four common
