Marked Variability in Distance‐Decay Patterns Suggests Contrasting Dispersal Ability in Abyssal Taxa

Global Ecology and Biogeography, Volume 34, Issue 1, January 2025.
ABSTRACT Aim We assess the role of spatial distance and depth difference in shaping beta diversity patterns across abyssal seascape regions. We measured the decrease of faunistic similarity across the northeast Pacific seafloor, to test whether species turnover rates differ between deep and shallow‐abyssal biogeographical provinces and whether these ...

Temporal and Spatial Distribution Patterns of Echinoderm Larvae in La Parguera, Puerto Rico

Revista de Biología Tropical, 2010
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 ...

Effects of Various Natural Diets on Gonad Development, Roe Quality, and Intestinal Microbiota of the Purple Sea Urchin (Heliocidaris crassispina)

Aquaculture Nutrition, Volume 2025, Issue 1, 2025.
The study analyzed the impact of different diets on the gonadal development of sea urchin Heliocidaris crassispina. Kelp (Laminaria japonica), corn (Zea mays), carrots (Daucus carota), and sweet potatoes (Ipomaea batatas) were used to continuously feed adults of H. crassispina for 50 days.

The Affinities of the Echinoidea [PDF]

The American Naturalist, 1909
THE recent discovery that the crinoids in their ontogeny increase the number of their anibulacral post-radial ossicles by the interpolation of numerous ossicles (in pairs) between the first two primitive brachials and the radial, forming what are known as "interpolated division series, " as well as by the addition of brachials in a linear series at the

Geochemical signatures and nanomechanical properties of echinoid tests from nearshore habitats of Florida: environmental and physiological controls on echinoid biomineralization [PDF]

PeerJ
The mechanisms that regulate minor and trace element biomineralization in the echinoid skeleton can be primarily controlled biologically (i.e., by the organism and its vital effects) or by extrinsic environmental factors.
