Defensive glandular structures in opisthobranch molluscs : From histology to ecology
TLDR
New results on defensive glandular structures as well as a compilation of literature data in sea slugs (Opisthobranchia, Gastropoda, Mollusca) are presented and an hypothetical scenario relating chemical ecology to histology is proposed. Expand
Missing link in the Southern Ocean: sampling the marine benthic fauna of remote Bouvet Island
TLDR
Samples taken during the RV “Polarstern" cruise ANTXXI/2 on 3 days in November 2003 and January 2004 are reported to contribute to identifying the role of Bouvet in the faunal exchange between the Sub- and high Antarctic. Expand
Chemical ecology and origin of defensive compounds in the Antarctic nudibranch Austrodoris kerguelenensis (Opisthobranchia: Gastropoda)
TLDR
It is suggested that A. kerguelenensis derives the bioactive diacylglycerides by de novo biosynthesis rather than by sequestration from its sponge diet, since the mollusk does not contain active metabolites in the viscera, and neither the active compounds nor precursors were detected in the sponge diet. Expand
Biological factors affecting larval growth in the nudibranch mollusc Hermissenda crassicornis (Eschscholtz, 1831)
TLDR
Both diet quantity and quality, as well as larval density, had an effect on larval growth and metamorphosis of Hermissenda crassicornis in the laboratory. Expand
Natural Products from Antarctic Colonial Ascidians of the Genera Aplidium and Synoicum: Variability and Defensive Role
TLDR
A series of colonial Antarctic ascidians from deep-water collections belonging to the genera Aplidium and Synoicum are analyzed to evaluate the incidence of organic deterrents and their variability and the possible origin of both types of metabolites is discussed. Expand
A sequestered soft coral diterpene in the aeolid nudibranch Phyllodesmium guamensis Avila, Ballesteros, Slattery, Starmer and Paul
TLDR
Phyllodesmium guamensis appears to utilize both a cryptic and nocturnal behavior pattern and a sequestered chemical defense to overcome intensive predation pressures on the reefs of Guam. Expand
Bone-eating worms from the Antarctic: the contrasting fate of whale and wood remains on the Southern Ocean seafloor
TLDR
The combined whale-fall and wood-fall experiment provides support to the hypothesis that the Antarctic circumpolar current is a barrier to the larvae of deep-water species that are broadly distributed in other ocean basins. Expand
Induction of metamorphosis in Hermissenda crassicornis larvae (Molluscs: Nudibranchia) by GABA, choline and serotonin
TLDR
Evidence is presented that artificial metamorphic inducers such as GABA, choline, and serotonin, alone or combined with the natural inducer T. crocea, can be used to improve the meetamorphic success in H. crassicornis larvae. Expand
