Experimentally based sea urchin gene regulatory network and the causal explanation of developmental phenomenology [PDF]
, 2009 Gene regulatory networks (GRNs) for development underlie cell fate specification and differentiation. Network topology, logic, and dynamics can be obtained by thorough experimental analysis.

Functional traits of two co-occurring sea urchins across a barren/forest patch system [PDF]
, 2013 Temperate rocky reefs may occur in two alternative states (coralline barrens and erect algal forests), whose formation and maintenance are often determined by sea urchin grazing.

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 ...

Identification and characterization of PlAlix, the Alix homologue from the Mediterranean sea urchin Paracentrotus lividus. [PDF]
, 2013 The sea urchin provides a relatively simple and tractable system for analyzing the early stages of embryo development. Here, we use the sea urchin species, Paracentrotus lividus, to investigate the role of Alix in key stages of embryogenesis, namely the ...

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

Relative abundance and size composition of subtidal abalone, Haliotis spp., sea urchin, Strongylocentrotus spp., and abundance of sea stars off Fitzgerald marine reserve, September 1993 [PDF]
, 1997 Data were collected at twenty-six dive stations at seven discrete latitudes along Fitzgerald Marine Reserve (FMR). Dive stations were targeted at three stratified depth zones: shallow (6.1 m), medium (10.7 m), and deep (16.8 m) in six of the seven ...

Estimating exploitable stock biomass for the Maine green sea urchin (Strongylocentrotus droebachiensis) fishery using a spatial statistics approach [PDF]
, 2005 The objective of this study was to investigate the spatial patterns in green sea urchin (Strongylocentrotus droebachiensis) density off the coast of Maine, using data from a fishery-independent survey program, to estimate the exploitable biomass of this
