    Selektion von hitzestresstoleranten Individuen bei der Weißbeingarnele Pennaeus vannamei (Peneidae) (2013)
    Details
    Publication Date: 2024-05-13
    Description: Wissenschaftliche Untersuchungen haben gezeigt, dass einige invasive Arten bzw. Populationen gegenüber Umweltstress robuster sind als nicht invasive Arten bzw. Populationen derselben Art. Es wird vermutet, dass die Toleranz gegenüber abiotischen Stressoren wahrscheinlich eine Schlüsseleigenschaft von invasiven Arten darstellt. Während des Transports von Individuen in einen neuen Lebensraum oder durch Stressereignisse könnten widrige abiotische Bedingungen eine Selektion stresstoleranter Individuen hervorrufen, was die erhöhte Stresstoleranz von invasiven Arten bzw. Populationen erklären könnte. Um dies zu testen, habe ich in einem Laborexperiment ein Transport- bzw. Stressereignis simuliert. In zwei unabhängigen Experimenten habe ich in einer Gruppe von Individuen der Weißbeingarnele Penaeus vannamei durch erhöhte Temperaturen mindestens 50 % Mortalität erzeugt. Hierbei wurden die Individuen in unabhängigen Replikaten für 13 Tage 37°C (Langzeit-Stressexperiment) bzw. für 2 h 41°C (Kurzzeit-Stressexperiment) Wassertemperatur ausgesetzt. Nach dieser ersten Stressphase wurde ein Teil der überlebenden gleichzeitig mit einer gleichen Anzahl an bis dahin nicht vorgestressten Individuen sofort wieder denselben erhöhten Temperaturen ausgesetzt und die Überlebenskurven in beiden Gruppen verglichen. Den übrigen überlebenden der ersten Stressphase wurde vor der zweiten Stressphase eine 13 Tage (Langzeit-Stressexperiment) bzw. 6 Tage (Kurzzeit-Stressexperiment) lange Erholungsphase gewährt, damit etwaige physiologische Anpassungen an Stressbedingungen abklingen konnten. Der Vergleich der Überlebenskurven einer vorgestressten Gruppe, die nach der ersten Stressphase direkt wieder Stressbedingungen ausgesetzt wurde und einer vorgestressten Gruppe, der eine Erholungsphase gewährt wurde, sollte Aufschluss darüber geben, ob eine mögliche erhöhte Stresstoleranz der vorgestressten Gruppen auf eine Selektion stresstoleranter Individuen oder physiologischer Anpassungen an Stressbedingungen zurückzuführen war. In beiden Experimenten zeigten die vorgestressten Gruppen, unabhängig davon, ob ihnen eine Erholungsphase gewährt wurde oder nicht, stets höhere Überlebensraten als die Gruppen, die nicht vorgestresst waren. Meine Ergebnisse legen einerseits nahe, dass es durch Temperaturstress zu einer physiologischen Stressabhärtung und dadurch zu erhöhten Überlebensraten der vorgestressten Individuen kam. Da Literaturdaten darauf hinweisen, dass die Erholungsphasen wahrscheinlich lang genug waren, um die physiologische Stressabhärtung in den vorgestressten Gruppen, denen eine Erholungsphase gewährt wurden, abklingen zu lassen, kann man andererseits annehmen, dass es durch den Temperaturstress bei P. vannamei zu einer Selektion stresstoleranterer Individuen gekommen ist. Dies konnte im Rahmen meiner Diplomarbeit jedoch nicht direkt bewiesen werden.

    Metabolic suppression during protracted exposure to hypoxia in the jumbo squid, Dosidicus gigas, living in an oxygen minimum zone (2014)
    COMPANY OF BIOLOGISTS LTD

    Description: The jumbo squid, Dosidicus gigas, can survive extended forays into the oxygen minimum zone (OMZ) of the Eastern Pacific Ocean. Previous studies have demonstrated reduced oxygen consumption and a limited anaerobic contribution to ATP production, suggesting the capacity for substantial metabolic suppression during hypoxic exposure. Here, we provide a more complete description of energy metabolism and explore the expression of proteins indicative of transcriptional and translational arrest that may contribute to metabolic suppression. We demonstrate a suppression of total ATP demand under hypoxic conditions (1% oxygen, PO2=0.8 kPa) in both juveniles (52%) and adults (35%) of the jumbo squid. Oxygen consumption rates are reduced to 20% under hypoxia relative to air-saturated controls. Concentrations of arginine phosphate (Arg-P) and ATP declined initially, reaching a new steady state (~30% of controls) after the first hour of hypoxic exposure. Octopine began accumulating after the first hour of hypoxic exposure, once Arg-P breakdown resulted in sufficient free arginine for substrate. Octopine reached levels near 30 mmol g−1 after 3.4 h of hypoxic exposure. Succinate did increase through hypoxia but contributed minimally to total ATP production. Glycogenolysis in mantle muscle presumably serves to maintain muscle functionality and balance energetics during hypoxia. We provide evidence that post-translational modifications on histone proteins and translation factors serve as a primary means of energy conservation and that select components of the stress response are altered in hypoxic squids. Reduced ATP consumption under hypoxia serves to maintain ATP levels, prolong fuel store use and minimize the accumulation of acidic intermediates of anaerobic ATP-generating pathways during prolonged diel forays into the OMZ. Metabolic suppression likely limits active, daytime foraging at depth in the core of the OMZ, but confers an energetic advantage over competitors that must remain in warm, oxygenated surface waters. Moreover, the capacity for metabolic suppression provides habitat flexibility as OMZs expand as a result of climate change.
