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.

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
