Ophiuroidea das regiões Antártica e Subantártica: 2. Variação em Gorgonocephalus chilensis ( Philippi) (Echinodermata, Ophiuroidea, Gorgonocephalidae) [PDF]
Foram examinados 198 exemplares de Gorgonocephalus chilensis das regiões antártica e subantartica, tendo-se em vista a variação de caracteres morfológicos externos. Foi constatada uma grande variação nas características morfológicas externas, que parece independer de localização geográfica.

Historical Biogeography of Spiny Lobsters in the Genus Panulirus (Achelata: Palinuridae)
ABSTRACT Aim Panulirus is the spiny lobster genus with the most living species, containing 22 recognised species split into two lineages distinguished by habitat preference. Diversification has been proposed to occur due to geographic events affecting the distribution of adults and the dispersal potential of long‐lived larvae by oceanic currents ...

Temporal 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 64μm mesh net between the new and full moon from April ...

ABSTRACT Aim This study characterises benthic habitats and associated biodiversity in three Japanese subduction trenches, and explores the effects of trench‐specific differences in large‐scale seismic events, disturbance and productivity regimes on habitat structure and assemblage composition.

Spatial and temporal variation in sponge spicule patches at Station M, northeast Pacific [PDF]
Changes in habitat-forming organisms can have complex consequences for associated species. Sessile epibenthic glass “plate” sponges (Porifera: Hexactinellida) are conspicuous inhabitants of soft-sediment abyssal areas and their siliceous spicules create ...

The core–periphery hypothesis (CPH) predicts that genetic diversity is greatest at the centre and lowest at the edges of a species' distribution because genetic diversity is a function of a species' abundance, which is also expected to be greatest at the centre and lowest at the edges of the distribution. Variants of the CPH include the ‘Ramped North' (
