Eutacticity in Sea Urchin Evolution [PDF]
Bulletin of Mathematical Biology, 2007 An eutactic star, in a n-dimensional space, is a set of N vectors which can be viewed as the projection of N orthogonal vectors in a N-dimensional space. By adequately associating a star of vectors to a particular sea urchin we propose that a measure of the eutacticity of the star constitutes a measure of the regularity of the sea urchin. Then we study

The challenge of managing the commercial harvesting of the sea urchin Paracentrotus lividus: advanced approaches are required [PDF]
PeerJ, 2020 Sea urchins act as a keystone herbivore in marine coastal ecosystems, regulating macrophyte density, which offers refuge for multiple species. In the Mediterranean Sea, both the sea urchin Paracentrotus lividus and fish preying on it are highly valuable ...

Control Strategies in Guanine Biocrystallization
Angewandte Chemie, EarlyView.Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

Uncommon southwest swells trigger sea urchin disease outbreaks in Eastern Atlantic archipelagos
Ecology and Evolution, 2020 Recurrent sea urchin mass mortality has recently affected eastern Atlantic populations of the barren‐forming sea urchin Diadema africanum. This new episode of die‐off affords the opportunity to determine common meteorological and oceanographic conditions

Beyond the Nature-Culture Frontier
Journal of Festive Studies, 2021 In order to challenge the culture–nature dichotomy, this article investigates two festivities centered around fishing and consuming the sea urchin in two different locations: the Suape Bay Ouriçada (Brazil) in the Southern Hemisphere, and the Carry-le ...

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
