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

Environmental 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.

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

Frontiers 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

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

Frontiers 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 ...

Linking Water to the Bottom: eDNA Study of Benthic Invertebrates and Invasive Species in the Venice Lagoon

Environmental DNA, Volume 7, Issue 2, March/April 2025.
This study used environmental DNA (eDNA) metabarcoding of superficial water samples to assess benthic invertebrate biodiversity in the Venice Lagoon. Sampling from surface water revealed 80 taxonomic units, mostly benthic species, including several invasive ones, with significant spatial and seasonal variations in community composition.

Spongivory by Fishes on Southwestern Atlantic Coral Reefs: No Evidence of Top-Down Control on Sponge Assemblages

Frontiers in Marine Science, 2018
Predator-prey dynamics can affect assemblage structure and ecosystem processes representing a central theory in ecology. In coral reef ecosystems, recent evidences have suggested that sponge assemblages in regions with high diversity, like the Caribbean,

Vertical Transmission of a Phylogenetically Complex Microbial Consortium in the Viviparous Sponge \u3cem\u3eIrcinia Felix\u3c/em\u3e [PDF]

, 2007
Many marine demosponges contain large amounts of phylogenetically complex yet highly sponge-specific microbial consortia within the mesohyl matrix, but little is known about how these microorganisms are acquired by their hosts.

Capitalizing on the wealth of chemical data in the accretionary structures of aquatic taxa: Opportunities from across the tree of life

Limnology and Oceanography Letters, Volume 10, Issue 1, Page 18-36, February 2025.
Abstract Aquatic organisms are natural data loggers and record chemical variations within hardened accretionary structures like shells and teeth. Chemical sclerochronology is the study of these chemical variations through time and how they are used to understand environmental change and the physiology and ecology of species.

Novel Gene Clusters for Secondary Metabolite Synthesis in Mesophotic Sponge‐Associated Bacteria

Microbial Biotechnology, Volume 18, Issue 2, February 2025.
The mesophotic coral ecosystem harbours a vast array of sponge species. Our metagenomic analysis reveals the bacterial diversity of mesophotic coral ecosystem sponges and their biosynthetic gene clusters of secondary metabolites, emphasising an underexplored resource for bioactive compounds.
