Global Diversity of Sponges (Porifera)
TLDR
Results obtained demonstrate that regional approaches to analytical biogeography are at present more likely to achieve insights into the biogeographic history of sponges than a global perspective, which appears currently too ambitious. Expand
Reconstructing ordinal relationships in the Demospongiae using mitochondrial genomic data.
TLDR
This work assembled a mitochondrial genomic dataset comprising all orders of demosponges that includes 17 new and five previously published complete demosponge mitochondrial genomes and assembled a modified method for the analysis of gene order data that works well when translocation of tRNA genes are more frequent than other rearrangements. Expand
Characterization of a Culturable Alphaproteobacterial Symbiont Common to Many Marine Sponges and Evidence for Vertical Transmission via Sponge Larvae
TLDR
This is the first report of the successful culture of a bacterial symbiont of a sponge that is transferred through the gametes and densely associated with the larvae rather than being evenly distributed throughout the mesohyl. Expand
Mitochondrial genomes of two demosponges provide insights into an early stage of animal evolution.
TLDR
The findings suggest that the evolution of the typical metazoan mtDNA has been a multistep process in which the compact genome organization and the reduced gene content were established prior to the reduction of tRNA and rRNA structures and the introduction of multiple changes of the translation code. Expand
Phylogenetic Relationships of the Marine Haplosclerida (Phylum Porifera) Employing Ribosomal (28S rRNA) and Mitochondrial (cox1, nad1) Gene Sequence Data
TLDR
Gene trees generated using 28S rRNA, nad1 and cox1 gene data, under maximum likelihood and Bayesian approaches, are highly congruent and suggest the presence of four clades of marine Haplosclerida. Expand
Silicon isotopic fractionation in marine sponges: A new model for understanding silicon isotopic variations in sponges
Abstract The silicon (Si) isotope (δ30Si) composition of deep-sea sponges from near Antarctica, subantarctic waters (Tasmania Seamounts) and subtropical waters north of New Zealand vary widelyExpand
Mirabamides A-D, depsipeptides from the sponge Siliquariaspongia mirabilis that inhibit HIV-1 fusion.
TLDR
Four new cyclic depsipeptides termed mirabamides A-D (1-4) have been isolated from the marine sponge Siliquariaspongia mirabilis and shown to potently inhibit HIV-1 fusion and demonstrate that these peptides can act at the early stages of HIV- 1 entry. Expand
Monitoring Bacterial Diversity of the Marine Sponge Ircinia strobilina upon Transfer into Aquaculture
TLDR
Culture-based and molecular techniques showed an increase in the Bacteroidetes and Alpha- and Gammaproteobacteria components of the bacterial community in aquaculture. Expand
Batzelladine alkaloids from the caribbean sponge Monanchora unguifera and the significant activities against HIV-1 and AIDS opportunistic infectious pathogens
Abstract Five new polycyclic guanidine alkaloids, 16β-hydroxycrambescidin 359 (1), batzelladines K, L, M, and N (2–5), along with the previously reported ptilomycalin A (6), crambescidine 800 (7),Expand
Spatial and Temporal Variability of Cytotoxic Metabolites in Populations of the New Zealand Sponge Mycale hentscheli
Intraspecific variation in the composition of three cytotoxic secondary metabolites from the New Zealand marine sponge Mycale hentscheli collected at two sites in central New Zealand was quantifiedExpand
