Four replacement names in fossil demosponges (Porifera: Demospongiae)

open access: yesRevista Brasileira de Paleontologia, 2022
The following replacement names in fossil Demospongiae are proposed: Trinacriarbuscula Ceccolini & Cianferoni nom. nov. = Arbuscula Parona, 1933 nec Bolivar, 1905; Iberogilletia Ceccolini & Cianferoni nom. nov. = Gilletia Lagneau-Herenger, 1962 nec Benderitter, 1923; Teutomastophorus Ceccolini & Cianferoni nom. nov.

Draft genomes shed light on the dual bacterial symbiosis that dominates the microbiome of the coral reef sponge Amphimedon queenslandica

open access: yesFrontiers in Marine Science, 2016
Amphimedon queenslandica is a coral reef demosponge that houses a low complexity and low abundance microbiota dominated by a proteobacterial duo for which draft genomes are presented here.

The complete mitochondrial genome of sponge Halichondria sp. (Demospongiae, Suberitida, Halichondriidae) from Dok-do

open access: yesMitochondrial DNA. Part B. Resources, 2019
The mitogenome sequence of Halichondria sp. was determined for the first time in this study. Specimens were identified as a new species belonging to genus Halichondria and more detailed taxonomic study is ongoing.

Divergence times in demosponges (Porifera): first insights from new mitogenomes and the inclusion of fossils in a birth-death clock model

open access: yesBMC Evolutionary Biology, 2018
Background Approximately 80% of all described extant sponge species belong to the class Demospongiae. Yet, despite their diversity and importance, accurate divergence times are still unknown for most demosponge clades.

Sponge Takeover from End-Permian Mass Extinction to Early Induan Time: Records in Central Iran Microbial Buildups

open access: yesFrontiers in Earth Science, 2021
The end-Permian mass extinction was the most severe biotic crisis in Earth’s history. In its direct aftermath, microbial communities were abundant on shallow-marine shelves around the Tethys.

The complete mitochondrial genome of sponge Pseudosuberites sp. (Demospongiae, Suberitida, Suberitidae) from Dokdo, Republic of Korea (East Sea)

open access: yesMitochondrial DNA. Part B. Resources, 2019
The mitogenome of Pseudosuberites sp. (Suberitida, Suberitidae) has been determined first in the genus Pseudosuberites. Assembled mitogenome was 23,502 bp in length, including 14 protein-coding genes, 25 transfer RNA, and 2 ribosomal RNA genes. The order

Agelasine Diterpenoids and Cbl-b Inhibitory Ageliferins from the Coralline Demosponge Astrosclera willeyana

open access: yesMarine Drugs, 2021
An extract of the coralline demosponge Astrosclera willeyana inhibited the ubiquitin ligase activity of the immunomodulatory protein Cbl-b. The bioassay-guided separation of the extract provided ten active compounds, including three new N-methyladenine ...

Environmental Flow Regimes for Dysidea avara Sponges [PDF]

open access: yes, 2008
The aim of our research is to design tank systems to culture Dysidea avara for the production of avarol. Flow information was needed to design culture tanks suitable for effective production. Water flow regimes were characterized over a 1-year period for
