Polymastiidae (Porifera: Demospongiae) of the Nordic and Siberian Seas

open access: yesJournal of the Marine Biological Association of the United Kingdom, 2017
Polymastiidae (Porifera: Demospongiae) of the Nordic and Siberian Seas are revised and compared with the related species of the North Atlantic based on the morphological data from the type and comparative material and the molecular data from fresh ...

Sulfated Polysaccharides in Marine Sponges: Extraction Methods and Anti-HIV Activity

open access: yesMarine Drugs, 2011
The extraction, fractionation and HIV-1 inhibition potential of polysaccharides extracted from three species of marine sponges, Erylus discophorus, Cliona celata and Stelletta sp., collected in the Northeastern Atlantic, is presented in this work.

The complete mitogenome of excavating sponge Thoosa mismalolli (Demospongiae, Tetractinellida, Thoosidae) from Northeastern Tropical Pacific

open access: yesMitochondrial DNA. Part B. Resources, 2020
The complete mitogenome of Thoosa mismalolli Carballo, Cruz-Barraza & Gómez, 2004 (Tetractinellida, Thoosidae) was sequenced. This is the first complete mitogenome of the suborden Thoosina and the third Tetractinellid so far.

DNA State Influences the Uptake and Persistence of Environmental DNA by Marine Sponge Natural Samplers

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
We present results from a mesocosm experiment testing the utility of marine sponges as natural samplers of eDNA and show the effect of DNA state on the capture and persistence of genetic material. We find a significant interaction between DNA state and sample type, with lower detection and concentration of extracellular DNA, compared to cellular DNA ...

First Report of the Coral-Killing Sponge Terpios hoshinota Rützler and Muzik, 1993 in Western Australia: A New Threat to Kimberley Coral Reefs?

open access: yesDiversity, 2019
The cyanobacteriosponge Terpios hoshinota has been reported throughout the Indo-Pacific including the Great Barrier Reef, Australia. The species encrusts live coral, giant clams, and other benthos and can be a threat to benthic communities on coral reefs.

Quantifying the Temporal Dynamics of Marine Biodiversity Under Anthropogenic Impacts Using eDNA Metabarcoding

open access: yesEnvironmental DNA, Volume 7, Issue 3, May–June 2025.
This study uses eDNA to explore marine biodiversity changes under anthropogenic impacts, with a focus on marine community dynamics. Through the use of eDNA metabarcoding, the research identified 814 ASVs across 617 marine families, noting drastic changes in biological communities over time, with different species dominating during different phases of ...

Evolution of g-type lysozymes in metazoa: insights into immunity and digestive adaptations

open access: yesFrontiers in Cell and Developmental Biology
Exploring the evolutionary dynamics of lysozymes is critical for advancing our knowledge of adaptations in immune and digestive systems. Here, we characterize the distribution of a unique class of lysozymes known as g-type, which hydrolyze key components

Spatial and Seasonal Biodiversity Variation in a Large Mediterranean Lagoon Using Environmental DNA Metabarcoding Through Sponge Tissue Collection

open access: yesEnvironmental DNA, Volume 7, Issue 3, May–June 2025.
Ecosystem monitoring is essential for preventing biodiversity loss, and in the Mar Menor lagoon (SE Spain), where intensive agriculture has led to eutrophication and mass mortality of marine fauna, it is critical for assessing the status of flora and fauna and informing conservation actions.

Assessing the Potential of Sponges (Porifera) as Indicators of Ocean Dissolved Si Concentrations

open access: yesFrontiers in Marine Science, 2017
We explore the distribution of sponges along dissolved silica (dSi) concentration gradients to test whether sponge assemblages are related to dSi and to assess the validity of fossil sponges as a palaeoecological tool for inferring dSi concentrations of ...
