A Comprehensive DNA Barcode Reference Library for the Macroinvertebrates of Scottish Seagrass Beds Using Oxford Nanopore Flongle Flowcells

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
In this study we use ONT Flongle Flowcells to produced DNA barcodes for 146 seagrass associated marine invertebrate OTUs collected from four seagrass beds in Scotland, targeting COI and 18S V4 regions. We generate the first DNA barcode reference library for seagrass beds in Scotland to support future biomonitoring of these priority habitats.

Body Polarity and Mineral Selectivity in the Demosponge Chondrosia reniformis

open access: yesThe Biological Bulletin, 1998
The skeleton of the common Mediterranean demosponge Chondrosia reniformis lacks endogenous spicules; but exogenous siliceous material is selectively incorporated into its collagenous ectosome, strengthening this layer. Nevertheless, the settling of sponge buds during asexual reproduction necessitates an active incorporation of the calcareous substratum

The phylogeny of halichondrid demosponges: past and present re-visited with DNA-barcoding data

open access: yes, 2012
Halichondrid sponges play a pivotal role in the classification of demosponges as changes in their classification has had direct consequences for the classification of Demospongiae. Historically, the systematics of halichondrids has been unstable.

Revisiting the silicon isotopic signal of sponge skeletons and its implications

open access: yesLimnology and Oceanography, Volume 70, Issue 9, Page 2480-2495, September 2025.
Abstract This study investigates the relationship between the silicon (Si) isotopic composition of sponge skeletal silica (δ30SibSi) and seawater characteristics in sponge habitats, specifically the concentration of dissolved silicic acid and its Si isotopic signature (δ30SidSi).

Marine Spongin: Naturally Prefabricated 3D Scaffold-Based Biomaterial

open access: yesMarine Drugs, 2018
The biosynthesis, chemistry, structural features and functionality of spongin as a halogenated scleroprotein of keratosan demosponges are still paradigms. This review has the principal goal of providing thorough and comprehensive coverage of spongin as a

Long Term Marine Biodiversity Monitoring in Coastal Antarctica: Are Fewer Rare Species Recruiting?

open access: yesGlobal Change Biology, Volume 31, Issue 7, July 2025.
Barnes et al. report 21 years of monitoring marine invertebrate recruitment to artificial substrata (settlement panels) with contextual environmental variables at the West Antarctic Peninsula. Traditional measures of recruitment and colonisation, such as density and space occupation (% cover) varied but with no obvious temporal trend.

Metazoan Diversity and Its Drivers: An eDNA Survey in the Pacific Gateway of a Changing Arctic Ocean

open access: yesEnvironmental DNA, Volume 7, Issue 2, March/April 2025.
In the face of climate change, organisms must adapt or shift their ranges to survive. Our study conducted the first COI marker‐based eDNA survey in the Pacific Gateway of the Arctic Ocean, analyzing seawater samples from the Bering Strait and Chukchi Sea.
