Mitochondrial dynamics underlying thermal plasticity of cuttlefish (Sepia officinalis) hearts.
In the eurythermal cuttlefish Sepia officinalis, performance depends on hearts that ensure systemic oxygen supply over a broad range of temperatures. We therefore aimed to identify adjustments in energetic cardiac capacity and underlying mitochondrial function supporting thermal acclimation and adaptation that could be crucial for the cuttlefish's competitive success in variable environments. T...
متن کاملAbiotic conditions in cephalopod (Sepia officinalis) eggs: embryonic development at low pH and high pCO2
Low pO2 values have been measured in the perivitelline fluids (PVF) of marine animal eggs on several occasions, especially towards the end of development, when embryonic oxygen consumption is at its peak and the egg case acts as a massive barrier to diffusion. Several authors have therefore suggested that oxygen availability is the key factor leading to hatching. However, there have been no mea...
متن کاملCuttlebone calcification increases during exposure to elevated seawater pCO2 in the cephalopod Sepia officinalis
Changes in seawater carbonate chemistry that accompany ongoing ocean acidification have been found to affect calcification processes in many marine invertebrates. In contrast to the response of most invertebrates, calcification rates increase in the cephalopod Sepia officinalis during long-term exposure to elevated seawater pCO2. The present trial investigated structural changes in the cuttlebo...
متن کاملCritical temperatures in the cephalopod Sepia officinalis investigated using in vivo 31P NMR spectroscopy.
The present study was designed to test the hypothesis of an oxygen limitation defining thermal tolerance in the European cuttlefish (Sepia officinalis). Mantle muscle organ metabolic status and pHi were monitored using in vivo 31P NMR spectroscopy, while mantle muscle performance was determined by recording mantle cavity pressure oscillations during ventilation and spontaneous exercise. Under c...
متن کاملGrowth and calcification in the cephalopod Sepia officinalis under elevated seawater pCO2
Ocean acidification and associated changes in seawater carbonate chemistry negatively influence calcification processes and depress metabolism in many calcifying marine invertebrates. We present data on the cephalopod mollusc Sepia officinalis, an invertebrate that is capable of not only maintaining calcification, but also growth rates and metabolism when exposed to elevated partial pressures o...
