Spatial and seasonal variation of the gonad index of Diadema antillarum (Echinodermata: Echinoidea) in the Canary Islands

چکیده
The sea urchin Diadema antillarum Philippi has a tropical-subtropical amphiatlantic distribution. According to Lessios et al. (2001), there are two genetically separate forms, one from the western and central Atlantic (D. antillarum-a) and one from the eastern Atlantic (D. antillarum-b). The latter form is found from the Madeira Archipelago to the Gulf of Guinea, including the Selvages, Canary and Cape Verde Islands.

A new species of Diadema (Echinodermata: Echinoidea: Diadematidae) from the eastern Atlantic Ocean and a neotype designation of Diadema antillarum (Philippi, 1845).
Diadenia africanum sp. nov. Rodríguez et al. 2013 occurs in the eastern Atlantic Ocean at depths of 1-80 meters off Ma- deira Islands, Salvage Islands, Canary Islands, Cape Verde Islands, Sâo Tome Islands and at the continental coast off Sen- egal and Ghana. This species was previously considered an eastern Atlantic population of D. antillarum. Genetic distances between the holotype of D. afric...
متن کاملNeoparamoeba branchiphila infections in moribund sea urchins Diadema aff. antillarum in Tenerife, Canary Islands, Spain.
A total of 109 sea urchins from 3 species collected in 2 localities off the coast of Tenerife Island, Spain, were examined for the presence of free-living amoebae in their coelomic fluid. Amoeba trophozoites were isolated exclusively from moribund individuals of long-spined sea urchins Diadema aff. antillarum (Philippi) (Echinoidea, Echinodermata) that manifested lesions related to sea urchin b...
متن کاملInfluence of wave exposure and habitat complexity in determining spatial variation of the sea urchin Diadema aff. antillarum (Echinoidea: Diadematidae) populations and macroalgal cover (Canary Islands - Eastern Atlantic Ocean)
Diadema aff. antillarum performs a key role in organizing and structuring rocky macroalgae assemblages in the Canary Islands; increased sea urchin population density can result in the formation of rocky grounds covered with crustose algae. In the Canary Islands this type of system alternates with non-crustose macroalgal systems. However, understanding of the process controlling formation, persi...
متن کاملPopulation Growth and Distribution of Diadema antillarum at Discovery Bay, Jamaica
The urchin Diadema antillarum Philippi (Echinodermata: Echinoidea) was extremely rare to absent from reefs throughout Jamaica during much of the 1980s and part of the 1990s following a Caribbean wide mortality event. This survey was conducted in 2007 to assess their distribution on the western forereef of Discovery Bay, Jamaica. Mean urchin densities of 3.93 ± 3.4 m -2 (mean ± SD) are the highe...
متن کاملTemporal and spatial distribution patterns of echinoderm larvae in La Parguera, Puerto Rico.
This study describes temporal and spatial abundance patterns of echinoderm larvae in La Parguera, Puerto Rico. For the temporal study, larvae were sampled by a series of monthly tows taken with a 64 microm mesh net between the new and full moon from April 2005 to July 2006, September 2006 and August 2007. In order to measure spatial variation of echinoderm larval abundances, oblique tows were t...
