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

Sex Determination in Sponges. [PDF]
Mol Reprod DevABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

Discovery of chitin in skeletons of non-verongiid Red Sea demosponges [PDF]
PLoS ONE, 2018 Marine demosponges (Porifera: Demospongiae) are recognized as first metazoans which have developed over millions of years of evolution effective survival strategies based on unique metabolic pathways to produce both biologically active secondary ...

Transcriptomic Insights Into the Immune Repertoire of an Antarctic Sponge. [PDF]
Ecol EvolAntarctic marine sponges are essential components of the benthic fauna, playing a crucial role in structuring this ecosystem through their own biological activities and their symbiotic relationships with diverse microorganisms. Yet, the transcriptional repertoire and the immune responses associated with interactions with microorganisms in this unique ...

The mitochondrial genomes of sponges provide evidence for multiple invasions by Repetitive Hairpin-forming Elements (RHE) [PDF]
BMC Genomics, 2009 Background The mitochondrial (mt) genomes of sponges possess a variety of features, which appear to be intermediate between those of Eumetazoa and non-metazoan opisthokonts.

Post-Embryonic Development and Formation of the Heterocoelic Aquiferous System in Two Species of Calcareous Sponges (Calcarea, Porifera). [PDF]
Mol Reprod DevABSTRACT We characterized the morphogenetic processes of larval metamorphosis and the development of the olynthus and heterocoelic aquiferous system (AS) in Sycettusa hastifera (syconoid) and Paraleucilla magna (leuconoid) (Porifera, Calcarea). Metamorphosis and development up to the olynthus were similar in both species.

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