Gigantism in unique biogenic magnetite at the Paleocene-Eocene Thermal Maximum [PDF]

, 2008
We report the discovery of exceptionally large biogenic magnetite crystals in clay-rich sediments spanning the Paleocene-Eocene Thermal Maximum (PETM) in a borehole at Ancora, New Jersey. Aside from previously-described abundant bacterial magnetofossils,

Lithistid sponges from submarine caves in the Mediterranean: taxonomy and affinities

Scientia Marina, 2011
Several lithistid sponges are described from Mediterranean caves occurring in the northwestern and Adriatic basins. In the Corallistidae, Neoschrammeniella bowerbanki and Neophrissospongia nolitangere are recorded for the first time from the ...

The coral-killing red sponge Clathria (Microciona) aceratoobtusa (Porifera: Demosponigiae) invades various coral communities of Gulf of Mannar Marine National Park, southeast India

The European Zoological Journal, 2020
Accounts of the encrusting, coral-killing sponges are increasing at an alarming rate. The present paper details about a thinly encrusting red sponge Clathria (Microciona) aceratoobtusa (Carter, 1887) which is invasive or locally spreading species and ...

Early animal evolution: a morphologist's view [PDF]

Royal Society Open Science, 2019
Two hypotheses for the early radiation of the metazoans are vividly discussed in recent phylogenomic studies, the ‘Porifera-first’ hypothesis, which places the poriferans as the sister group of all other metazoans, and the ‘Ctenophora-first’ hypothesis ...

Foundation Species Abundance Influences Food Web Topology on Glass Sponge Reefs

Frontiers in Marine Science, 2020
Foundation species support communities across a wide range of ecosystems. Non-trophic interactions are considered the primary way foundation species influence communities, with their trophic interactions having little impact on community structure.

The early expansion and evolutionary dynamics of POU class genes. [PDF]

, 2014
The POU genes represent a diverse class of animal-specific transcription factors that play important roles in neurogenesis, pluripotency, and cell-type specification. Although previous attempts have been made to reconstruct the evolution of the POU class,

Host population genetics and biogeography structure the microbiome of the sponge Cliona delitrix

Ecology and Evolution, 2020
Sponges occur across diverse marine biomes and host internal microbial communities that can provide critical ecological functions. While strong patterns of host specificity have been observed consistently in sponge microbiomes, the precise ecological ...

Microbial communities and bioactive compounds in marine sponges of the family Irciniidae-a review [PDF]

, 2014
Marine sponges harbour complex microbial communities of ecological and biotechnological importance. Here, we propose the application of the widespread sponge family Irciniidae as an appropriate model in microbiology and biochemistry research. Half a gram

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

Marine 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.
