The debated question of asymmetrical rhynchonellids (Brachiopoda, Rhynchonellida): examples from the Late Cretaceous of Western Europe

open access: yesBSGF - Earth Sciences Bulletin, 2020
Many Cretaceous asymmetrical rhynchonellid brachiopods (Brachiopoda, Rhynchonellida) have long been considered as Rhynchonella difformis (Valenciennes in Lamarck, 1819).

Complete mitochondrial genome of Laqueus Japonicus (Brachiopoda, Terebratulida, Laqueidae)

open access: yesMitochondrial DNA. Part B. Resources, 2017
In this study a complete mitochondrial genome of the species, Laqueus japonicus was sequenced and analysed. The mitochondrial genome size is 14,267 bp with 20.2% A, 15.7% C, 27.1% G, and 37.0% T nucleotide distributions.

NEW DATA ON THE LATE MIOCENE BRACHIOPOD FAUNA OF TETTI BORELLI (PIEDMONT, N ITALY)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2018
After a small brachiopod fauna was published in 2010 from the Tortonian Sant’Agata Fossili Formation of Tetti Borelli (N Italy), two new and more numerous brachiopod collections turned up from this locality.

Molluscan Shells, Spicules, and Gladii Are Evolutionarily Deeply Conserved. [PDF]

open access: yesJ Exp Zool B Mol Dev Evol
Evolutionarily conserved transcription factor encoding genes and other genes are expressed in the epithelia that give rise to spicules (green) and/or shells (blue) in developmental stages of diverse mollusks, including polyplacophorans, aplacophorans, scaphopods, and cephalopods.

Recent brachiopods from the Persian Gulf and their biogeographical significance

open access: yesScientia Marina, 2008
Two brachiopod species Discradisca indica (Dall, 1920) and Argyrotheca jacksoni Cooper, 1973, together with Lingula sp., have been identified from the Persian Gulf.

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 521-544, July 2026.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Scalable Benthic Biomonitoring: Trade‐Offs Between Bulk and Environmental DNA Metabarcoding Across Sediment Types

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
Direct eDNA metabarcoding is the most scalable method for large benthic monitoring programs, provided that sampling effort is increased to compensate for slightly lower per‐sample biodiversity recovery. ABSTRACT DNA metabarcoding offers prospects to assess benthic biodiversity in a more scalable and comprehensive way, but processing methods remain ...
