An evaluation of sponge-associated amphipods from the Antarctic Peninsula

Antarctic Science, 2009
AbstractNearshore marine benthic algal communities along the western Antarctic Peninsula harbour extremely high densities of amphipods that probably play important roles in nutrient and energy flow. This study extends our evaluation of the importance of amphipods in the nearshore Antarctic Peninsular benthic communities and focuses on sponge ...

Rhapsamine, a Cytotoxin from the Antarctic Sponge Leucetta leptorhapsis

Tetrahedron Letters, 1997
Abstract Bioassay guided fractionation of the cytotoxic crude extract from the antarctic sponge Leucetta leptorhapsis has resulted in the isolation of rhapsamine ( 1 ), a linear C28 polyene terminally substituted by 1,3-diaminoglycerol groups. © 1997 Elsevier Science Ltd.

Antibacterial defenses and palatability of shallow-water Antarctic sponges

Hydrobiologia, 2017
Marine sponges are exposed to predation as well as to a wide array of potentially harmful microorganisms, and therefore they often possess chemical activity against putative predators and/or pathogens. Some crude extracts from sponges are effective in avoiding microbial colonization or potential infections, and in protecting them against predation ...

Discorhabdin Alkaloids from the Antarctic Sponge Latrunculia apicalis

Journal of Natural Products, 1995
An Antarctic collection of Latrunculia apicalis contained as its major secondary metabolite the pigment discorhabdin C as well as a previously unreported pigment, discorhabdin G. Discorhabdin alkaloids have a variety of pharmacological and ecological bioactivities, including the mediation of interactions with the potential predator Perknaster fuscus, a

Antarctic sponges as prokaryotic diversity and biotechnology hot-spots

2018
Polar Regions are experiencing multiple environmental stressors and the increasing contaminant influxes are likely becoming more severe. As filter-feeders, in Porifera ingestion becomes the primary route in the uptake and accumulation of particle-associated contaminants, which may accumulate in animal tissues. Porifera also provide an important habitat
