Demographic Models and Behavioral Assessments Uncover Distinct Species Histories in the Pseudocryptic Nudibranch Genus <i>Hermissenda</i>. [PDF]

open access: yesEcol Evol
We reconstructed the speciation history of the recently split pseudocryptic nudibranch genus Hermissenda, finding divergence times in the Pleistocene (1.29–0.55 mya). Demographic modeling and behavioral experiments show no gene flow and assortative mating between sympatric species H. crassicornis (s.s.) and H.

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 ...

Mitochondrial Genomes of Three <i>Melampus</i> Species (Ellobiidae; Gastropoda). [PDF]

open access: yesEcol Evol
The mitochondrial genomes of three gastropod species from the family Ellobiidae—Melampus bidentatus, Melampus jaumei, and Melampus gundlachi—were assembled and annotated and found to have a gene order that diverges from the conserved gene order that is recovered in most genera within Ellobiidae and—more generally—within Euthyneura.

The marine Heterobranchia (Mollusca: Gastropoda) fauna of the Aeolian archipelago (Tyrrhenian Sea). First contribution: Lipari and Vulcano [PDF]

open access: yes, 2023
It is here presented the first faunistic list of the marine Heterobranchia fauna of Lipari and Vulcano, the two southernmost islands of the Aeolian archipelago. Through the examination of ten dive sites (six in Lipari and four in Vulcano), it was found a

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 ...

The first record of Gyraulus cf. acronicus (Gastropoda, Heterobranchia, Planorbidae) in waterbodies of the Novaya Zemlya Archipelago

open access: yesFauna Norvegica, 2023
The knowledge on diversity of freshwater molluscs in the Arctic islands of the Russian Federation remains incomplete. The present study provides the first record of the North Palaearctic species Gyraulus cf.

The Glacidorbidae (Mollusca: Gastropoda: Heterobranchia) of Australia [PDF]

open access: yesRecords of the Australian Museum, 2000
The heterobranch gastropod family Glacidorbidae (?Pulmonata) is known only from temperate Australia and Chile. The Australian taxa are reviewed and three new genera, Benthodorbis, Striadorbis and Tasmodorbis are described based on differences in their shells, especially the protoconchs, and in their opercula and radulae.

Assessment of mitochondrial genomes for heterobranch gastropod phylogenetics

open access: yesBMC Ecology and Evolution, 2021
Background Heterobranchia is a diverse clade of marine, freshwater, and terrestrial gastropod molluscs. It includes such disparate taxa as nudibranchs, sea hares, bubble snails, pulmonate land snails and slugs, and a number of (mostly small-bodied ...
