Diel activity correlates with colour pattern morphology of heterobranch sea slugs. [PDF]
J Anim EcolThe authors show that daytime activity fundamentally shapes the appearance of prey animals to potential predators and that colour pattern phenotypes likely associated with visual signalling are predominantly found in diurnal species of sea slugs. This study showcases novel methodology combining comparative phylogenetic analyses, animal vision modelling,

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

Diversity, 2023 Five Chromodoris species from North Sulawesi, Indonesia, were investigated for their sequestration of marine natural products. The cytotoxic 2-thiazolidinone macrolide latrunculin A (LatA) was the major metabolite in all examined Chromodoris species, as ...

An update to the 2014 nomenclator of Valvatidae [PDF]
ZooKeys, 2022 This contribution is an update to the 2014 compilation of all supra- and (infra-) specific taxa of extant and fossil Valvatidae, a group of freshwater operculate snails near the base of Heterobranchia with a nearly worldwide distribution.

Crustaceans and Marine Heterobranchia: A New Symbiotic Relationship in the Mediterranean Sea
Diversity, 2021 The “solar-powered” Elysia timida (Risso, 1818) is an endemic Mediterranean sacoglossan living in rocky substrates at shallow water. During a scuba dive, one E. timida was photographed and collected.

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

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

Diversity, 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 ...

Assessment of mitochondrial genomes for heterobranch gastropod phylogenetics
BMC 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 ...
