The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

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 ...

First Specimen Based Record of Anthessius cucullatus (Copepoda: Cyclopoida: Anthessiidae) Associated with Aplysia spp. (Gastropoda: Aplysiida: Aplysiidae) from Coastal Waters of Kagoshima, Southern Japan

open access: yesSpecies Diversity, 2023
A species of cyclopoid copepod Anthessius cucullatus Lee and Kim, 2021 (Anthessiidae) is newly recorded based on both sexes collected from three species of the sea slug genus Aplysia Linnaeus, 1767, i.e., Ap. dactylomela Rang, 1828, Ap.

Transcriptional changes following long-term sensitization training and in vivo serotonin exposure in Aplysia californica. [PDF]

open access: yesPLoS ONE, 2012
We used Aplysia californica to compare the transcriptional changes evoked by long-term sensitization training and by a treatment meant to mimic this training, in vivo exposure to serotonin.

Novel calpain families and novel mechanisms for calpain regulation in Aplysia. [PDF]

open access: yesPLoS ONE, 2017
Calpains are a family of intracellular proteases defined by a conserved protease domain. In the marine mollusk Aplysia californica, calpains are important for the induction of long-term synaptic plasticity and memory, at least in part by cleaving protein

Characterization of an Aplysia vasotocin signaling system and actions of posttranslational modifications and individual residues of the ligand on receptor activity

open access: yesFrontiers in Pharmacology, 2023
The vasopressin/oxytocin signaling system is present in both protostomes and deuterostomes and plays various physiological roles. Although there were reports for both vasopressin-like peptides and receptors in mollusc Lymnaea and Octopus, no precursor or

Reducing unwanted catches of trammel nets: experimental results of the “guarding net” in the caramote prawn, Penaeus kerathurus, small-scale fishery of the Ligurian Sea (western Mediterranean)

open access: yesScientia Marina, 2018
This study aimed to test the effectiveness of a “guarding net”, a device placed at the bottom of a trammel net, for reducing unwanted catches in the caramote prawn trammel net fishery of the Ligurian Sea.

Identification of three elevenin receptors and roles of elevenin disulfide bond and residues in receptor activation in Aplysia californica

open access: yesScientific Reports, 2023
Neuropeptides are ubiquitous intercellular signaling molecules in the CNS and play diverse roles in modulating physiological functions by acting on specific G-protein coupled receptors (GPCRs). Among them, the elevenin signaling system is now believed to
