Metabolites from an Antarctic sponge-associated bacterium, Pseudomonas aeruginosa.
In an ongoing survey of the bioactive potential of microorganisms associated with marine invertebrates, the culture media of a sponge-associated bacterial strain of Pseudomonas aeruginosa was foundExpand
Cold-water marine natural products.
Marine natural products isolated from organisms collected from cold-water habitats are described. Emphasis is on bioactive compounds from tunicates, sponges, microbes, bryozoans, corals, algae,Expand
Ecology of Antarctic Marine Sponges: An Overview1
Abstract Sponges are important components of marine benthic communities of Antarctica. Numbers of species are high, within the lower range for tropical latitudes, similar to those in the Arctic, andExpand

Overview of the chemical ecology of benthic marine invertebrates along the western Antarctic peninsula.
TLDR
The present article reviews the current knowledge of chemical ecology of benthic marine invertebrates comprising communities along the Western Antarctic Peninsula (WAP), a region of Antarctica that is both physically and biologically distinct from the rest of the continent. Expand
Surface sequestration of chemical feeding deterrents in the Antarctic sponge Latrunculia apicalis as an optimal defense against sea star spongivory
TLDR
Results support the predictions of the optimal defense theory as L. apicalis sequesters its defensive chemistry (discorhabdin G) in its most vulnerable surface tissues, where the likelihood of predation from sea stars is highest. Expand
The Mg-Calcite Composition of Antarctic Echinoderms: Important Implications for Predicting the Impacts of Ocean Acidification
The Southern Ocean is considered to be the canary in the coal mine with respect to the first effects of ocean acidification (OA). This vulnerability is due to naturally low carbonate ionExpand
Feeding rates of common Antarctic gammarid amphipods on ecologically important sympatric macroalgae
TLDR
Regression analysis indicated that differences in amphipod macroalgal palatability are most likely related to other factors including physical and/or chemical deterrents. Expand
Palatability and chemical anti-predatory defenses in common ascidians from the Antarctic Peninsula
TLDR
Test the ability of acidified krill pellets to deter fish and sea star predators and found that, while fish readily ingested acidified food pellets, sea stars were deterred at pH 5 or less, thus either organic or inorganic chemical defenses explain defense in 5 of the 7 ascidian species found unpalatable to sea stars.

Palmerolide A, a cytotoxic macrolide from the antarctic tunicate Synoicum adareanum.
Palmerolide A, a 20-membered macrocyclic polyketide bearing carbamate and vinyl amide functionality, was isolated from the tunicate Synoicum adareanum collected from the vicinity of Palmer Station onExpand
