Sea urchin roe quality within urchin barrens and improvement through kelp restoration
EcosphereSea urchin overgrazing is a major cause of kelp loss and consequently sea urchin removal is frequently promoted as a tool for restoring kelp in urchin barrens. While many sea urchin species support high‐end roe fisheries, roe condition is generally lower

An Integrated Canonical and Non-Canonical Wnt Signaling Network Controls Early Anterior-Posterior Axis Formation in Sea Urchin Embryos. [PDF]
J Dev BiolWnt signaling is an ancient developmental mechanism that drives the initial specification and patterning of the primary axis in many metazoan embryos. Yet, it is unclear how exactly the various Wnt components interact in most Wnt-mediated developmental ...

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.

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.

Influence of Winter Storms on the Sea Urchin Pathogen Assemblages
Frontiers in Marine Science, 2022 In recent years, recurrent sea urchin mass mortalities in the Canary Islands have been registered. These mortality-related events have decimated 93% of the eastern Atlantic populations of the barren-forming sea urchin Diadema africanum.

Trophic cascades induced by lobster fishing are not ubiquitous in southern California kelp forests. [PDF]
PLoS ONE, 2012 Fishing can trigger trophic cascades that alter community structure and dynamics and thus modify ecosystem attributes. We combined ecological data of sea urchin and macroalgal abundance with fishery data of spiny lobster (Panulirus interruptus) landings ...
