UV Light Reveals the Diversity of Jurassic Shell Colour Patterns: Examples from the Cordebugle Lagerstätte (Calvados, France) [PDF]

open access: yes, 2015
Viewed under UV light the diverse and exceptionally well-preserved molluscs from the Late Jurassic Cordebugle Konservat Lagerstätte (Calvados, Normandy, France) reveal fluorescent fossil shell colour patterns predating the oldest previously known ...

Evolution of the Cdk4/6-Cdkn2 system in invertebrates. [PDF]

open access: yesGenes Cells
Hypothesis on the evolution of the Cdkn2 locus. (a) Loss of Cdkn2 occurred multiple times. (b) Evolution of microsynteny at the Cdkn2 locus. Cdkn2e is a hypothetical transient gene. Abstract The cell cycle is driven by cyclin‐dependent kinases (Cdks). The decision whether the cell cycle proceeds is made during G1 phase, when Cdk4/6 functions.

Final report : benthic samples taken from the Padre Island National Seashore [PDF]

open access: yes, 1992
From March 1989 through January 1992 sediment samples were taken from subtidal areas within the boundary of the Padre Island National Seashore. These samples were taken as part of a large multidisciplinary study to determine how a hot, hypersaline ...

Use of axonal projection patterns for the homologisation of cerebral nerves in Opisthobranchia, Mollusca and Gastropoda [PDF]

open access: yes, 2013
Introduction: Gastropoda are guided by several sensory organs in the head region, referred to as cephalic sensory organs (CSOs). These CSOs are innervated by distinct nerves.

Evaluating Probe Design for Phylogenomics Across Taxonomic Scales: First Steps for Applying Ultraconserved Elements in an Understudied Class (Mollusca: Polyplacophora). [PDF]

open access: yesMol Ecol Resour
ABSTRACT Ultraconserved elements (UCEs) have become a powerful tool for phylogenomics, but probe sets optimized for one lineage often perform inconsistently when applied in others. Here, we designed and tested new UCE probe sets derived from both genome and transcriptome data of an understudied molluscan class, Polyplacophora (chitons).

Heterobranch sea slugs (Mollusca: Gastropoda) from Ascension Island, South Atlantic Ocean [PDF]

open access: yes, 2017
The small volcanic island of Ascension is situated in the middle of the South Atlantic Ocean, more than 1500 km from the coast of Africa, its nearest continental area. To date, eight 'opisthobranch' species were reported from the island. As a result of a

Primary Productivity and Habitat Depth Shape Developmental Mode in European Marine Gastropods. [PDF]

open access: yesEcol Evol
Thorson's rule suggests that marine gastropods in colder, high‐latitude regions tend to have non‐pelagic (non‐drifting) larval development. However, this study on 94 European gastropod species found that the rule disappears when examined at finer spatial scales, with temperature and phylogeny having little influence.

Designation of a neotype for the dwarf sea hare Aplysia concava G. B. Sowerby I, 1833, and a review of the status of Aplysia norfolkensis G. B. Sowerby II, 1869 (Mollusca: Heterobranchia)

open access: yesRecords of the Australian Museum, 2021
A recent revision of the globally distributed dwarf sea hare Aplysia parvula sensu lato split that species into 10 separate taxa. As Australian specimens were not included in this revision, further study using material from the south west Pacific was ...
