Unique Polyhalogenated Peptides from the Marine Sponge Ircinia sp. [PDF]

open access: yesMarine Drugs, 2020
Two new bromopyrrole peptides, haloirciniamide A (1) and seribunamide A (2), have been isolated from an Indonesian marine sponge of the genus Ircinia collected in the Thousand Islands (Indonesia).

Phylogenetically and spatially close marine sponges harbour divergent bacterial communities. [PDF]

open access: yesPLoS ONE, 2012
Recent studies have unravelled the diversity of sponge-associated bacteria that may play essential roles in sponge health and metabolism. Nevertheless, our understanding of this microbiota remains limited to a few host species found in restricted ...

New Scalarane Sesterterpenoids from the Formosan Sponge Ircinia felix [PDF]

open access: yesMarine Drugs, 2015
Five new scalarane sesterterpenoids, felixins A–E (1–5), were isolated from the Formosan sponge Ircinia felix. The structures of scalaranes 1–5 were elucidated on the basis of spectroscopic analysis.

Competition for waterborne food resources among tropical shallow-water sponges. [PDF]

open access: yesEcology
Abstract A recurrent theme in marine ecology is that the community dynamics of sessile, suspension‐feeding animals is primarily limited by the availability of space, but in some habitats, filtration by these organisms may locally deplete water column resources, setting the stage for exploitative competition for food.

Collagenic architecture and morphotraits in a marine basal metazoan as a model for bioinspired applied research. [PDF]

open access: yesJ Morphol, 2022
A prototype of connective system, almost exclusively based on collagenic networks, is zoomed in the model sponge Ircinia retidermata (Porifera: Keratosa). We focused on topographic distribution, spatial layout, microtraits, and/or morphogenesis of these collagenic structures. Ectosome and outer endosome are the active fibrogenetic areas where exogenous

Uncovering the Potent Antiviral Activity of the Sesterterpenoids from the Sponge Ircinia Felix Against Human Adenoviruses: from the Natural Source to the Total Synthesis. [PDF]

open access: yesChemistry
Isolation, structure elucidation, biological activity, and total synthesis of ircinialactam J, a novel sesterterpene lactam produced by the sponge Ircinia felix, is presented. Ircinialactam J displays a significant antiviral activity against Human Adenoviruses (11 times more active than cidofovir®) without cytotoxicity.

CO I barcoding reveals new clades and radiation patterns of Indo-Pacific sponges of the family Irciniidae (Demospongiae: Dictyoceratida). [PDF]

open access: yesPLoS ONE, 2010
DNA barcoding is a promising tool to facilitate a rapid and unambiguous identification of sponge species. Demosponges of the order Dictyoceratida are particularly challenging to identify, but are of ecological as well as biochemical importance.Here we ...

Validation of key sponge symbiont pathways using genome‐centric metatranscriptomics

open access: yesEnvironmental Microbiology, Volume 25, Issue 12, Page 3207-3224, December 2023., 2023
The sponge microbiome is hypothesised to carry out a range of metabolic functions that improve the fitness of the host. Our study tested whether these metabolic functions were active across three different sponge species by analysing the gene‐expression of their symbionts.

NAMBER: A biotic index for assessing the ecological quality of mesophotic biogenic reefs in the northern Adriatic Sea

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 3, Page 298-311, March 2023., 2023
Abstract The aim of the present study was to propose a biotic index (North Adriatic Mesophotic BiogEnic Reefs, NAMBER) suitable for assessing the ecological quality of the mesophotic biogenic reefs of the northern Adriatic continental shelf based on photographic sampling.
