Pectinidae WILKES 1810

open access: yes, 2019
PECTINIDAE WILKES, 1810 FIG. 37 UCMP 412480 is a mold of a small indeterminate Pectinidae. The cast is about 7 mm high with 10, possibly 11, strong radial ribs, with the suggestion of finer concentric sculpture on some ribs. A possible posterior auricle is present although the impression is very faint and difficult to distinguish, and no sculpture is ...

Carotenoid extraction from the gonad of the scallop Nodipecten nodosus (Linnaeus, 1758) (Bivalvia: Pectinidae) Extração de carotenóides da gônada da vieira Nodipecten nodosus (Bivalvia: Pectinidae)

open access: yesBrazilian Journal of Biology, 2009
In marine bivalve mollusks, unsaturated molecules called carotenoids are present in the natural diet and play an important role in different biological process, especially in reproduction. In order to gain more insights into these compounds in Nodipecten

Comparative mitogenomic analyses of three scallops (Bivalvia: Pectinidae) reveal high level variation of genomic organization and a diversity of transfer RNA gene sets

open access: yesBMC Research Notes, 2009
Background It can be seen from the available mollusk mitogenomes that the family Pectinidae exhibits the most variation in genome organization. In this study, comparative mitogenomic analyses were performed for three scallops from the subfamily ...

Downcurrent variation in submarine channel‐fill architecture from the shelf to upper slope

open access: yesSedimentology, EarlyView.
ABSTRACT The transition between the shelf and the upper slope is often considered an area of sediment bypass, where steeper gradients increase flow velocities and maintain particles in suspension. In addition to transferring sediments into deeper basins, upper‐slope areas can also host channelised submarine deposits.
