Bioremediation Capabilities of Hymeniacidon perlevis (Porifera, Demospongiae) in a Land-Based Experimental Fish Farm

open access: yesJournal of Marine Science and Engineering, 2022
The expansion of aquaculture practices in coastal areas can alter the balance of microbial communities in nearby marine ecosystems with negative impacts on both farmed and natural species, as well as on human health through their consumption.

A therapeutic potential for marine skeletal proteins in bone regeneration [PDF]

open access: yes, 2013
A vital ingredient for engineering bone tissue, in the culture dish, is the use of recombinant matrix and growth proteins to help accelerate the growth of cultivated tissues into clinically acceptable quantities.

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.

Genome-wide analysis of the sox family in the calcareous sponge Sycon ciliatum: multiple genes with unique expression patterns

open access: yesEvoDevo, 2012
Background Sox genes are HMG-domain containing transcription factors with important roles in developmental processes in animals; many of them appear to have conserved functions among eumetazoans.

Post‐Embryonic Development and Formation of the Heterocoelic Aquiferous System in Two Species of Calcareous Sponges (Calcarea, Porifera)

open access: yesMolecular Reproduction and Development, Volume 92, Issue 10, October 2025.
ABSTRACT We characterized the morphogenetic processes of larval metamorphosis and the development of the olynthus and heterocoelic aquiferous system (AS) in Sycettusa hastifera (syconoid) and Paraleucilla magna (leuconoid) (Porifera, Calcarea). Metamorphosis and development up to the olynthus were similar in both species.

Sponge community of the western Black Sea shallow water caves: diversity and spatial distribution [PDF]

open access: yesPeerJ, 2018
Marine caves possess unique biocoenotic and ecological characteristics. Sessile benthic species such as sponges associated with cave habitats typically show a marked zonation from the cave entrance towards the end of the cave.

Putative cross-kingdom horizontal gene transfer in sponge (Porifera) mitochondria [PDF]

open access: yes, 2006
Background The mitochondrial genome of Metazoa is usually a compact molecule without introns. Exceptions to this rule have been reported only in corals and sea anemones (Cnidaria), in which group I introns have been discovered in the cox1 and nad5 genes.

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).

Cytotoxicity and Glycan-Binding Properties of an 18 kDa Lectin Isolated from the Marine Sponge <em>Halichondria </em><em>o</em><em>kadai</em>

open access: yesToxins, 2012
A divalent cation-independent lectin—HOL-18, with cytotoxic activity against leukemia cells, was purified from a demosponge, <em>Halichondria okadai</em>. HOL-18 is a 72 kDa tetrameric lectin that consists of four non-covalently bonded 18 kDa

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.
