Permian–Triassic evolution of the Bivalvia: Extinction-recovery patterns linked to ecologic and taxonomic selectivity [PDF]

open access: yes, 2016
The Bivalvia is an important benthic clade that was relatively less affected than other benthos during the Permian–Triassic (P–Tr) biotic crisis, reporting losses of 85%, 64%, and 32% at the species, genus and family levels, respectively.

Paleoecology and proliferation of the bivalve Chondrodonta joannae (Choffat) in the upper Cenomanian (Upper Cretaceous) Adriatic Carbonate Platform of Istria (Croatia) [PDF]

open access: yes, 2020
Chondrodonta joannae (Choffat) is a morphologically variable oyster-like bivalve with a predominately calcitic shell. An exceptional exposure of C. joannae-bearing strata of late Cenomanian age crops out along the seaside in northern Istria (Croatia) and

Palaeoecology of the late Permian mass extinction and subsequent recovery [PDF]

open access: yes, 2015
Climate warming during the latest Permian is associated with the most severe mass extinction event of the Phanerozoic, and the expansion of hypoxic and anoxic conditions into shallow shelf settings.

Marine Animal-Derived Compounds and Autophagy Modulation in Breast Cancer Cells [PDF]

open access: yes, 2021
It is known that in breast cancer biology, autophagy mainly plays a cytoprotective and anti-apoptotic role in vitro, being conceivably responsible for cell resistance to drug exposure and a higher metastatic attitude in vivo.

The genome sequence of the Pacific oyster, Magallana gigas (Thunberg, 1793) [version 1; peer review: 2 approved]

open access: yesWellcome Open Research
We present a genome assembly from an individual Magallana gigas (the Pacific oyster; Mollusca; Bivalvia; Ostreida; Ostreidae). The genome sequence is 564.0 megabases in span. Most of the assembly is scaffolded into 10 chromosomal pseudomolecules.

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

open access: yesSedimentology, Volume 73, Issue 1, Page 40-82, January 2026.
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 ...
