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.

Phase-Shift Dynamics of Sea Urchin Overgrazing on Nutrified Reefs. [PDF]
PLoS ONE, 2016 Shifts from productive kelp beds to impoverished sea urchin barrens occur globally and represent a wholesale change to the ecology of sub-tidal temperate reefs.

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

Sea urchin waste as valuable alternative source of calcium in laying hens' diet. [PDF]
PLoS ONEAnnually, 3000-3500 tons of sea urchins are harvested in the Mediterranean Sea, with only their gonads being consumed (10-30% of the total weight), leaving the rest as waste.

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

Testing sea urchin and green sea turtle consumption of the allelopathic macroalga Galaxaura divaricata [PDF]
Ecology and EvolutionGalaxaura divaricata is a partially calcified macroalga that hampers coral recruitment, growth, and recovery via the excretion of allelopathic secondary metabolites. Herbivorous fishes are not major consumers of Galaxaura spp.

Sea urchin harvest inside marine protected areas: an opportunity to investigate the effects of exploitation where trophic upgrading is achieved [PDF]
PeerJ, 2022 Background Marine protected areas (MPAs) usually have both positive effects of protection for the fisheries’ target species and indirect negative effects for sea urchins. Moreover, often in MPAs sea urchin human harvest is restricted, but allowed.
