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 ...

Modelling Palaeodistributions in Marine Environments: A Review

open access: yesJournal of Biogeography, Volume 53, Issue 5, May 2026.
ABSTRACT Aim This scoping review (ScR) synthesises the current literature on the application of Species Distribution Models (SDM) to past marine environments. We assess how these models have been used to reconstruct past environmental suitability, track biogeographical shifts and investigate long‐term ecological dynamics, while identifying key ...

A new genus of Triassic discinid brachiopod and re-evaluating the taxonomy of the group—evolutionary insights into autecological innovation of post-Palaeozoic discinids [PDF]

open access: yesActa Palaeontologica Polonica
The discinid brachiopod from the Lower Triassic Osawa Formation in the Southern Kitakami Terrane, Japan, exhibited a unique morphological combination of a narrow pedicle track (listrium) and a V-shaped large depressed area, thereby suggesting an ...

Orientation of Telotrematous Brachiopoda [PDF]

open access: yesNature, 1953
A STUDY of the development of the rhynchonellid, Tegulorhynchia nigricans, Sowerby, shows the larva to be furnished with two pairs of large tufts of long setae set on the hind margin of the mantle rudiment. The members of one pair lie dorso-laterally, those of the other pair laterally.

The Permian–Triassic transition in Türkiye: New insights and 3D outcrop models for accessible, reproducible and sustainable fieldwork

open access: yesThe Depositional Record, Volume 12, Issue 2, April 2026.
We studied the Permian–Triassic successions of south‐western Türkiye at five locations, synthesised sedimentological and palaeontological data, putting it into a consistent stratigraphic framework and incorporating 3D digital outcrop models. Abstract The Permian–Triassic transition is characterised by major environmental changes and the largest known ...
