New Sesterterpenes from the Antarctic Sponge Suberites sp.

open access: yesMarine Drugs
Chemical investigation of the Antarctic sponge Suberites sp. has previously led to the identification of new suberitane derivatives, some of which show bioactivity toward respiratory syncytial virus (RSV).

Neosuberitenone, a New Sesterterpenoid Carbon Skeleton; New Suberitenones; and Bioactivity against Respiratory Syncytial Virus, from the Antarctic Sponge Suberites sp.

open access: yesMarine Drugs, 2023
Respiratory syncytial virus (RSV) is a highly contagious human pathogen that poses a significant threat to children under the age of two, and there is a current need for new small molecule treatments. The Antarctic sponge Suberites sp.

The Biodiversity of Retreating Glaciers Leaves an Ecological Legacy in Emerging Soil Communities

open access: yesGlobal Change Biology, Volume 32, Issue 8, August 2026.
We provide the first multi‐taxa assessment of biodiversity transitions across the supraglacial‐proglacial interface, using eDNA metabarcoding across five glacier systems. Recently deglaciated soils resemble supraglacial communities taxonomically and functionally, markedly for microbes and weakly for animals, with microbial similarity declining rapidly ...

Functional Analysis of Ligand‐Gated Chloride Channels in a Cnidarian Sheds Light on the Evolution of Inhibitory Signaling

open access: yesAdvanced Science, Volume 13, Issue 41, 22 July 2026.
We uncover a large variety of putative inhibitory ligand‐gated ion channels (LGICs) in the phylum Cnidaria, the sister group to all bilaterian animals. Phylogenetic analysis suggests a complex evolutionary history of inhibitory LGICs with diverse neurotransmitter ligands.

Multiscale patterns of sponge diversity on Western Atlantic coral reefs: insights from the Southern Gulf of Mexico and the Mexican Caribbean

open access: yesFrontiers in Marine Science
IntroductionSponges are increasingly dominant components of coral reefs in the Tropical Western Atlantic, yet patterns of their diversity across spatial scales remain poorly quantified.MethodsWe applied a hierarchical sampling design across 13 reefs and ...

Exploring Mesophotic Coral Reef Boundaries Using Environmental DNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 4, July‐August 2026.
Environmental DNA (eDNA) metabarcoding reveals boundaries along depth gradients in shallow and mesophotic coral reefs. Analysis of metazoan amplicon sequence variants (ASVs) uncovers changes in community structure from shallow to deep reefs, highlighting a localized eDNA footprint and its potential for monitoring mesophotic and deep‐sea habitats ...

Effect of Acute Thermal Stress Exposure on Ecophysiological Traits of the Mediterranean Sponge Chondrilla nucula: Implications for Climate Change

open access: yesBiology, 2023
As a result of climate change, the Mediterranean Sea has been exposed to an increase in the frequency and intensity of marine heat waves in the last decades, some of which caused mass mortality events of benthic invertebrates, including sponges.

Evaluating 18S Phylogenetic Placement Accuracy to Uncover Hidden Diversity in Non‐Bilaterian Animals

open access: yesEnvironmental DNA, Volume 8, Issue 4, July‐August 2026.
We assembled the largest curated non‐bilaterian 18S reference dataset and demonstrate that barcode choice strongly influences phylogenetic placement accuracy. Full‐length 18S provides the most robust framework for biodiversity discovery, recovering previously unknown non‐bilaterian lineages, whereas V9 should be interpreted with caution. ABSTRACT Small

Reproduction and Development in Calcareous Sponges: A Panorama of the Last Two Centuries

open access: yesMolecular Reproduction and Development, Volume 93, Issue 7, July 2026.
ABSTRACT Nearly 200 years ago, scientists began examining reproductive cells in calcareous sponges (Calcarea, Porifera). Since then, 238 studies have been published, encompassing descriptions of gametes and embryos (including ultrastructural studies), life history, asexual reproduction, regeneration, and molecular aspects of development.
