Multiple Processes Regulate Long-Term Population Dynamics of Sea Urchins on Mediterranean Rocky Reefs
We annually monitored the abundance and size structure of herbivorous sea urchin populations (Paracentrotus lividus and Arbacia lixula) inside and outside a marine reserve in the Northwestern Mediterranean on two distinct habitats (boulders and vertical walls) over a period of 20 years, with the aim of analyzing changes at different temporal scales in relation to biotic and abiotic drivers. P. ...
متن کاملEvolutionary crossroads in developmental biology: sea urchins.
Embryos of the echinoderms, especially those of sea urchins and sea stars, have been studied as model organisms for over 100 years. The simplicity of their early development, and the ease of experimentally perturbing this development, provides an excellent platform for mechanistic studies of cell specification and morphogenesis. As a result, echinoderms have contributed significantly to our und...
متن کاملThe Effects of Ocean Acidification on the Development of Lytechinus variegatus (Green Sea Urchins)
Breanna C. DeGroot University of North Carolina Wilmington Faculty Mentor: Heather Koopman University of North Carolina Wilmington ABSTRACT The purpose of this experiment was to study the effects of ocean acidification on early spicule formation and development in Lytechinus variegatus (green sea urchins). After induced spawning of adult green sea urchins occurred the larvae were placed in a co...
متن کاملTrophic ecology of sea urchins in coral-rocky reef systems, Ecuador
Sea urchins are important grazers and influence reef development in the Eastern Tropical Pacific (ETP). Diadema mexicanum and Eucidaris thouarsii are the most important sea urchins on the Ecuadorian coastal reefs. This study provided a trophic scenario for these two species of echinoids in the coral-rocky reef bottoms of the Ecuadorian coast, using stable isotopes. We evaluated the relative pro...
متن کاملEchinoderms Display Morphological and Behavioural Phenotypic Plasticity in Response to Their Trophic Environment
The trophic interactions of sea urchins are known to be the agents of phase shifts in benthic marine habitats such as tropical and temperate reefs. In temperate reefs, the grazing activity of sea urchins has been responsible for the destruction of kelp forests and the formation of 'urchin barrens', a rocky habitat dominated by crustose algae and encrusting invertebrates. Once formed, these urch...
