Widespread Distribution of Poribacteria in Demospongiae [PDF]

Applied and Environmental Microbiology, 2009
ABSTRACT Poribacteria were found in nine sponge species belonging to six orders of Porifera from three oceans. Phylogenetic analysis revealed four distinct poribacterial clades, which contained organisms obtained from several different geographic regions, indicating that the distribution of poribacteria is cosmopolitan.

Sponging up diversity: Evaluating metabarcoding performance for a taxonomically challenging phylum within a complex cryptobenthic community

Environmental DNA, 2022
Despite their ecological importance, sponges are often avoided in biodiversity studies and monitoring programs because they are notoriously difficult to identify using morphological or molecular methods. Here, we investigate the metabarcoding performance

Chemotaxonomy of Agelas (Porifera: Demospongiae) [PDF]

Biochemical Systematics and Ecology, 1992
The secondary metabolite content of four different species of Agelas (Porifera) from the West Indies has been studied. All the compounds isolated are already known metabolites whose identification was confirmed by comparison of their spectral properties with those reported in the literature.

Embryo development of Corticium candelabrum (Demospongiae: Homosclerophorida) [PDF]

Invertebrate Biology, 2007
Abstract. Corticium candelabrum is a homosclerophorid sponge widespread along the rocky Mediterranean sublittoral. Scanning and transmission electron microscopy were used to describe the gametes and larval development. The species is hermaphroditic. Oocytes and spermatocytes are clearly differentiated in April.

Implementation of the benefits of symbiotic bacteria in Demospongiae sponges in Indonesian waters using the literature study method [PDF]

BIO Web of Conferences
A Demospongiae sponge is an organism that can interact with symbiotic bacteria. Symbiotic bacteria form a specific mutualistic symbiosis that creates a stable and beneficial association with their hosts. This review examines the diversity and benefits of
