Affinities of the family Sollasellidae (Porifera, Demospongiae). II. Molecular evidence [PDF]

, 2007
This is the second part of a revision and re-classification of the demosponge family Sollasellidae, and an example of a successful use of combined morphological and molecular data. Sollasella had been a poorly known, long forgotten taxon, placed incertae

Early evolution of the LIM homeobox gene family

BMC Biology, 2010
Background LIM homeobox (Lhx) transcription factors are unique to the animal lineage and have patterning roles during embryonic development in flies, nematodes and vertebrates, with a conserved role in specifying neuronal identity.

Benthic foraminifers and siliceous sponge spicules assemblages in the Quaternary rhodolith rich sediments from Pontine Archipelago shelf [PDF]

, 2016
The bottom samples (Quaternary in age) of two cores (CS1 and Caro1) collected at 60 and 122 m water depth in the marine area near Ponza Island (Pontine Archipelago, Tyrrhenian Sea) are investigated.

Potential for host-symbiont communication via neurotransmitters and neuromodulators in an aneural animal, the marine sponge Amphimedon queenslandica

Frontiers in Neural Circuits, 2023
Interkingdom signalling within a holobiont allows host and symbionts to communicate and to regulate each other’s physiological and developmental states.

Archaeal diversity in deep-sea sediments estimated by means of different Terminal-Restriction Fragment Length Polymorphisms (T-RFLP) protocols [PDF]

, 2009
Despite the increasing recognition of the quantitative importance of Archaea in all marine systems, the protocols for a rapid estimate of Archaeal diversity patterns in deep-sea sediments have been only poorly tested yet.

First Report on Chitin in a Non-Verongiid Marine Demosponge: The Mycale euplectellioides Case

Marine Drugs, 2018
Sponges (Porifera) are recognized as aquatic multicellular organisms which developed an effective biochemical pathway over millions of years of evolution to produce both biologically active secondary metabolites and biopolymer-based skeletal structures ...

Associations of Commercial Fisheries and Cold‐Water Corals and Sponges

Fish and Fisheries, Volume 27, Issue 2, Page 116-129, March 2026.
Three metrics for determining whether the marine life that are landed by commercial fisheries are associated with cold‐water corals and sponges: (a) Adjacent; (b) General Proximity; and (c) Habitat. The relationship between these structure forming invertebrates (SFI) and fisheries is robust across analytical approaches.

Diverse RNA interference strategies in early-branching metazoans

BMC Evolutionary Biology, 2018
Background Micro RNAs (miRNAs) and piwi interacting RNAs (piRNAs), along with the more ancient eukaryotic endogenous small interfering RNAs (endo-siRNAs) constitute the principal components of the RNA interference (RNAi) repertoire of most animals.

Barcoding‐Inferred Biodiversity of Shallow‐Water Indo‐Pacific Demosponges

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim The Indo‐Pacific is the world's largest marine biogeographic region. It is characterised by different degrees of connectivity among its subregions and harbours the majority of demosponge species currently known to science. Comparisons between regional sponge faunas have been undertaken in the past, mostly based on morphological species ...
