Precise monitoring of porpoising behaviour of Adélie penguins determined using acceleration data loggers.
A new method using acceleration data loggers enabled us to measure the porpoising behaviour of Adélie penguins (Pygoscelis adeliae), defined as a continuous rapid swimming with rhythmic serial leaps. Previous hydrodynamic models suggested that leaping would be energetically cheaper when an animal swims continuously at depths of less than three maximum body diameters below the water surface. In ...
متن کاملPhysiological response to feeding in little penguins.
Specific dynamic action (SDA), the increase in metabolic rate above resting levels that accompanies the processes of digestion and assimilation of food, can form a substantial part of the daily energy budget of free-ranging animals. We measured heart rate (fH) and rate of oxygen consumption (VO2) in 12 little penguins while they digested a meal of sardines in order to determine whether they sho...
متن کاملOesophageal temperature differences in children.
It has been shown that the temperature of the oesophagus in the anaesthetized and intubated adult is not uniform along its length. There is an area below the distal end of the endotracheal tube that is affected by ventilation and the temperature of the inspired gases. This area does not extend into the lowest quarter of the oesophagus (Stupfel and Severinghaus, 1956; Whitby and Dunkin, 1963, 19...
متن کاملPlankton community properties determined by nutrients and size-selective feeding
The potential impacts of climate change on marine planktonic ecosystems remain difficult to predict. Climate forcing can alter nutrient availability and predator community composition, and here we show that these shifts may dramatically alter plankton trophic structure, size distributions and biomass. We modeled phytoplankton and zooplankton as a highly resolved size spectrum with size-dependen...
متن کاملFeeding behaviour in rabbits
As a monogastric herbivore, the rabbit presents a unique feeding behaviour compared to other domestic animals, since he belongs to the Lagomorpha order (Leporidae family: rabbits and hares, Grassé and Dekeuser, 1955), and consequently possess a main specificity that is the caecotrophy. For recall (see details in chapter 1), the caecotrophy is a complete behaviour involving an excretion and an i...
