Observations on the Benthic Heterobranch “Sea Slugs” (Mollusca: Gastropoda) of Lampedusa, the Southernmost Island of Italy (MPA Isole Pelagie)

Journal of Marine Science and Engineering
Thanks to their striking shapes and colors, heterobranch “sea slugs” are probably the most sought-after group of marine critters by scuba divers around the world.

Barcoding against a paradox? Combined molecular species delineations reveal multiple cryptic lineages in elusive meiofaunal sea slugs

BMC Evolutionary Biology, 2012
Background Many marine meiofaunal species are reported to have wide distributions, which creates a paradox considering their hypothesized low dispersal abilities.

Evolution of the Cdk4/6–Cdkn2 system in invertebrates

Genes to Cells, Volume 29, Issue 11, Page 1037-1051, November 2024.
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.

Diversity and function of fluorescent molecules in marine animals

Biological Reviews, Volume 99, Issue 4, Page 1391-1410, August 2024.
ABSTRACT Fluorescence in marine animals has mainly been studied in Cnidaria but is found in many different phyla such as Annelida, Crustacea, Mollusca, and Chordata. While many fluorescent proteins and molecules have been identified, very little information is available about the biological functions of fluorescence.

A Middle Triassic Cassian‐type fauna (Pelsa‐Vazzoler Lagerstätte) and the adaptive radiation of the Modern evolutionary fauna

Papers in Palaeontology, Volume 10, Issue 4, July/August 2024.
Abstract We describe a high‐diversity silicified assemblage of marine molluscs (Pelsa‐Vazzoler Lagerstätte) from the upper Ladinian of the Agordo Dolomites (northeastern Italy). New data on the Triassic rebound, after the end‐Permian mass extinction, constrain it to an interval of relatively stable climatic conditions.

Resource level modifies heatwave responses in the freshwater snail Lymnaea stagnalis

Freshwater Biology, Volume 69, Issue 5, Page 692-704, May 2024.
Abstract Predicting climate change‐mediated environmental effects on organisms is difficult because their direction and strength may depend on multiple ecological factors that vary in nature. This is because the effects of environmental factors often interact.

The Revolution of Small Snails and the Early Modern Evolutionary Fauna

Diversity
The species richness of major clades and functional groups among gastropods, a key element of Modern Evolutionary Fauna (MEF), underlines the dominant role of carnivorous Caenogastropoda and Heterobranchia, including small ectoparasites and micrograzers,

The fossil record of freshwater Gastropoda – a global review

Biological Reviews, Volume 99, Issue 1, Page 177-199, February 2024.
ABSTRACT Gastropoda are an exceptionally successful group with a rich and diverse fossil record. They have conquered land and freshwater habitats multiple times independently and have dispersed across the entire globe. Since they are important constituents of fossil assemblages, they are often used for palaeoecological reconstruction, biostratigraphic ...

Sea Slugs (Mollusca, Gastropoda, Heterobranchia) from the Medes Islands (Costa Brava, NE Spain): Biodiversity and Ecological Study over a Decade

Diversity
The Mediterranean Sea faces escalating environmental pressures from the unsustainable exploitation of resources and insufficient management. Marine protected areas (MPAs), such as the Parc Natural del Montgrí, les Illes Medes i el Baix Ter (PNMMBT) on ...

Testing the Species Status of the Chromodorid Nudibranch Goniobranchus aureopurpureus (Mollusca: Gastropoda)

Species Diversity
The chromodorid nudibranch Goniobranchus aureopurpureus (Collingwood, 1881) is characterized by numerous yellow spots on a white mantle that is bordered with purple spots.
