Extreme Phenotypic Plasticity in Metabolic Physiology of Antarctic Demosponges [PDF]
Frontiers in Ecology and Evolution, 2016 Seasonal measurements of the metabolic physiology of four Antarctic demosponges and their associated assemblages, maintained in a flow through aquarium facility, demonstrated one of the largest differences in seasonal strategies between species and their associated sponge communities.

Long Term Marine Biodiversity Monitoring in Coastal Antarctica: Are Fewer Rare Species Recruiting? [PDF]
Glob Chang BiolBarnes et al. report 21 years of monitoring marine invertebrate recruitment to artificial substrata (settlement panels) with contextual environmental variables at the West Antarctic Peninsula. Traditional measures of recruitment and colonisation, such as density and space occupation (% cover) varied but with no obvious temporal trend.

Demospongic Acids Revisited [PDF]
Marine Drugs, 2010 The well-known fatty acids with a D5,9 unsaturation system were designated for a long period as demospongic acids, taking into account that they originally occurred in marine Demospongia sponges. However, such acids have also been observed in various marine sources with a large range of chain-lengths (C16–C32) and from some terrestrial plants with ...

Methylome Profiling of a Deuterostome Invertebrate Using Oxford Nanopore Technology (ONT). [PDF]
Mol Ecol ResourABSTRACT DNA methylation is crucial for genome regulation and provides key insights into the interaction between genetics and environmental factors, offering valuable perspectives for ecological research. However, knowledge of DNA methylation patterns in nonmodel invertebrates remains limited.

Seventeen new complete mtDNA sequences reveal extensive mitochondrial genome evolution within the Demospongiae. [PDF]
PLoS ONE, 2008 Two major transitions in animal evolution--the origins of multicellularity and bilaterality--correlate with major changes in mitochondrial DNA (mtDNA) organization.

Molecular biodiversity of Red Sea demosponges [PDF]
Marine Pollution Bulletin, 2016 Sponges are important constituents of coral reef ecosystems, including those around the Arabian Peninsula. Despite their importance, our knowledge on demosponge diversity in this area is insufficient to recognize, for example, faunal changes caused by anthropogenic disturbances.

Diversity, 2021 Confined marine environments are particularly susceptible to climate change and anthropic pressures. Indeed, the long-term monitoring of benthic assemblages in these environments allows us to understand the direction of changes over time.

Some aspects of silica deposition in lithistid demosponge desmas [PDF]
Microscopy Research and Technique, 2003 AbstractTransmitted light microscope and SEM observations of various growth stages, including very young forms, of lithistid demosponge spicules called desmas provided a wealth of new observations on silica deposition in desmas of most lithistid demosponge groups.

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux. [PDF]
J Exp Zool B Mol Dev EvolEpithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.
