    Abstract In der vorliegenden Arbeit werden mittels biochemischer, elektrophoretischer und elektronenmikroskopischer Methoden ausgewaehlte Parameter des Lipidstoffwechsels des Suedlichen See-Elefanten (Mirounga leonina) untersucht. Die Ergebnisse werden dann als Ausdruck der besonderen Anpassung an den polaren Lebensraum diskutiert. Fruehere Untersuchungen bei Weddellrobben (Leptonychotes weddellii) zeigten hohe Konzentrationen an Cholesterin (400-1000 mg/dl) und trotz der fetthaltigen Nahrung vergleichsweise niedrige Serumkonzentrationen an Triacylglyceriden (30-90 mg/dl). Histologische Untersuchungen an Arterien der Weddellrobben und eines See-Elefanten zeigten jedoch keine pathologischen Veraenderungen der Blutgefaesse. Beim Menschen hingegen wurde anhand zahlreicher epidemiologischer Studien der Zusammenhang zwischen pathologischen Blutfettwerten und kardiovaskulaeren Erkrankungen nachgewiesen. Hierdurch wurden in der Lipiddiagnostik zahlreiche Labormethoden etabliert. Eine Auswahl dieses Spektrums wird fuer die Untersuchungen am Suedlichen See-Elefanten angewendet und diskutiert. Die Freilanduntersuchungen fanden in zwei Expeditionen (1995/96 und 1996/97) im deutsch-argentinischen Dallmann-Labor auf King George Island, Antarktis, statt. (gekuerzt)

    Abstract The occurrence and composition of toxic algae, and presence of viruses and other human microbial pathogens in production areas of mussels are factors determining suitability of mussel products for human consumption. As bivalves feed by filtering large volumes of water, potentially toxic viruses, algae, and bacteria as well as phytoplankton are ingested. With the expansion of mussel aquaculture and subsequent increase in human consumption of mussel products, improved risk management is required for consumer protection. For example, shifting production to offshore areas (e.g. wind farms) can decrease the hazards of infection due to dilution of contaminants, and increase overall health of mussels. In addition, the deployment of off-bottom cultivation methods such as longlines increases the condition index, growth, and aesthetic appearance of mussels. However, other hazards like algal toxins not yet monitored on a regular basis, may play a more important rule offshore. Here, we present an analysis of biological, economic, and consumer health-related aspects of mussel cultivation under near- and offshore conditions.

    Abstract Representatives of the Antarctic food web (krill, cephalopod, fish, penguin, seal) of the area around Elephant Island and from the Weddell Sea were analysed for the most recalcitrant organochlorine compounds. Due to sorption of the compounds to sinking particles and accumulation in sediments, two benthic fish species (Gobionotothen gibberifrons, Chaenocephalus aceratus) feeding on benthos invertebrates and fish reflected significantly increasing concentrations within a decade (1987-1996), while a benthopelagic species (Champsocephalus gunnari) feeding on krill did not. In the pelagic food chain, lipid normalised concentrations of all compounds increased from Antarctic krill to fish proving that biomagnification of highly lipophilic pollutants (log octanol-water partition coefficient>5) occurs in water-breathing animals. As top predators Weddell and southern elephant seals (Leptonychotes weddellii, Mirounga leonina) biomagnified the persistent organic pollutants relative to krill 30-160 fold with the exception of hexachlorobenzene, the levels of which were lower than in fish indicating its intense specific elimination.
