Una nueva especie de Tomura (Gastropoda, Heterobranchia, Cornirostridae) del Caribe

open access: green, 1998
A new marine valvatoidean gastropod species is described. Based on the radula structure and morphology of the soft parts, the species is assigned to the genus Tomura Pilsbry and McGinty ...

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).

Checklist of the micromolluscs in the intertidal zone of the Yellow Sea and Bohai Sea, China [PDF]

open access: yesBiodiversity Data Journal, 2023
The diversity of the sedimentary environment and molluscs is rich in the intertidal zone of the Yellow Sea and Bohai Sea. At present, many of the investigations focus on macromolluscs, while the diversity of micromolluscs is seriously underestimated.In ...

The Sea Slug Doriopsilla areolata Bergh, 1880 (Mollusca, Gastropoda) in the Mediterranean Sea: Another Case of Cryptic Diversity

open access: yesDiversity, 2022
The Mediterranean Sea diversity is still far from being fully disclosed. Marine Heterobranchia are one of the most paradigmatic species-rich groups, with many recent systematic studies revealing the high density of new, cryptic, and endemic species ...

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.

Cryptic species in tropic sands--interactive 3D anatomy, molecular phylogeny and evolution of meiofaunal Pseudunelidae (Gastropoda, Acochlidia) [PDF]

open access: yes, 2011
Towards realistic estimations of the diversity of marine animals, tiny meiofaunal species usually are underrepresented. Since the biological species concept is hardly applicable on exotic and elusive animals, it is even more important to apply a ...

Two Seas for One Great Diversity: Checklist of the Marine Heterobranchia (Mollusca; Gastropoda) from the Salento Peninsula (South-East Italy)

open access: yesDiversity, 2020
The Salento peninsula is a portion of the Italian mainland separating two distinct Mediterranean basins, the Ionian and the Adriatic seas. Several authors have studied the marine Heterobranchia (Mollusca, Gastropoda) fauna composition living in the ...

From Mud to Meat: Comparative Metabarcoding Reveals Two Different Evolutionary Paths to Carnivory in a Group of Meiofaunal Annelids. [PDF]

open access: yesMol Ecol
ABSTRACT Evolutionary transitions to carnivory represent profound shifts in feeding mode that are often accompanied by widespread changes in organismal function, behaviour and ecology. Such transitions have evolved numerous times among animals, and predator–prey interactions have been major drivers of animal evolution.
