Developmental role of dpp in the gastropod shell plate and co-option of the dpp signaling pathway in the evolution of the operculum [PDF]

open access: yes, 2012
The operculum is a novel structure in gastropod molluscs. Because the operculum shows notable similarities to the shell plate, we asked whether there were an evolutionary link between these two secretory organs.

Observations on the intertidal barnacles (Cirripedia: Balanomorpha) at Fossil Island, Tasman Peninsula: physical tolerances, orientation and fertilisation [PDF]

open access: yes, 1986
Six species of barnacle are found intertidally at Fossil Island. Tolerances of the species to desiccation and temperature could be related to their position on the shore.

Surface growth kinematics via local curve evolution [PDF]

open access: yes, 2014
A mathematical framework is developed to model the kinematics of surface growth for objects that can be generated by evolving a curve in space, such as seashells and horns.

Facies mosaic distribution and stratigraphic disorder of a mixed carbonate–siliciclastic tidal succession

open access: yesSedimentology, EarlyView.
ABSTRACT Complex stratigraphic arrangements may be generated through lateral facies transitions from the strata of aeolian depositional systems into bordering peritidal deposits. In such scenarios, sedimentary architectural complexity and associated facies heterogeneities are governed by the interplay between autogenic processes inherent to tidal ...

Screening Relaxants for Efficacy and Effects on Growth for Greenlip Abalone, Haliotis laevigata Donovan

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Relaxants are used in abalone aquaculture to facilitate handling, transport and grading stock, with minimal injury, stress, immune suppression and mortality. Benzocaine has been commonly used as an abalone relaxant but negative behavioural responses to exposure have been observed, and in some countries it has a withholding period, precluding ...

Hominin and carnivore roles during the formation of the early Middle Pleistocene site of Loreto (Venosa Basin, southern Italy)

open access: yesJournal of Quaternary Science, Volume 40, Issue 7, Page 1252-1268, October 2025.
ABSTRACT The site of Loreto (Venosa Basin, Italy) was first discovered in 1929 and subsequently excavated during the latter half of the 20th century. The excavation revealed three archaeo‐palaeontological levels, with the lowermost level (Level A) yielding the largest number of remains.
