eDNA Metabarcoding Enhances Aquaculture Impact Monitoring Across Microbial and Benthic Metazoan Communities in Understudied Tropical Environments

open access: yesEnvironmental DNA, Volume 8, Issue 4, July‐August 2026.
Benthic community responses to aquaculture organic matter enrichment remain poorly understood in tropical low‐input farms typical of scattered island socio‐ecosystems. Detecting these responses requires sensitive approaches such as eDNA metabarcoding across multiple biological groups.

Complete mitochondrial genome analysis of Aquilonastra batheri (Echinodermata, Asteroidea, Valvatida)

open access: yesMitochondrial DNA. Part B. Resources, 2018
In this study, we determined the complete mitochondrial genome sequences of Aquilonastra batheri. This is the first study on mitochondrial genome sequencing of the genus Aquilonastra belonging to the family Asterinidae, order Valvatida, and class ...

BeeGees: A High‐Throughput Protein‐Coding DNA Barcode Recovery Pipeline Tailored for Genome Skims of Museum Specimens

open access: yesMolecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Natural history collections are unparalleled archives of global biodiversity, yet most specimens remain molecularly uncharacterised due to the technical challenges of historical DNA (hDNA), including degradation, low endogenous content and contamination.

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,

Biogeography of intertidal invertebrates is influenced by latitude along the west coast of Australia

open access: yesEcography, Volume 2026, Issue 6, June 2026.
Along the west coast of Australia, intertidal rock platforms support high invertebrate diversities that provide vital ecosystem services, yet patterns in diversity are not well understood. Here, we document and examine the invertebrate assemblages on intertidal rock platforms in Western Australia and delineate ecoregions according to assemblage ...

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.

Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 6, June 2026.
Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.
