    Brood patch temperature during provocation of common eiders in Ny-Ålesund, Svalbard (2001)

    Notizen: In this short note we describe the behaviour and body changes of three incubating female common eiders (Somateria mollissima) during provocation made by humans approaching the nest. The study site was near the settlement of Ny-Ålesund, Svalbard. Temperture transmitters were implanted subcutaneously at the brood patch and data recorded using a VHF receiver. We found that the female experiment exhibited a passive defence response (“freezing”), accompanied by a significant drop in brood patch temperature (0.6 °C) during provocation; this temperature drop lasted for 5 minutes. These accord with other studies of the physiological changes which the passive defence response in birds and other animals.

    Thermogenesis in newly hatched Eider (Somateria mollissima) and Long-tailed Duck (Clangula hyemails) ducklings and Barnacle Goose (Branta leucopsls) goslings (1986)

    Notizen: Oxygen consumption and body temperature were recorded in Eider and Long-tailed ducklings and in Barnacle goslings less than 4 days old. In some ducklings organ temperatures during cold exposure and oxydative capacity of various organs were also measured. Both ducklings and goslings were perfectly homeothermic down to -10°C ambient temperature. Eider hatchlings had a lower critical temperature of 23°C, Long-tailed of 29°C, and Barnacle goslings of21°C. During cold stress the area below the spine was slightly warmer than the thigh and liver. The high oxydative capacities of these organs compared to yolk, kidney, and gut indicate that the homeothermy in newly hatched ducklings and goslings depends on a combination of good insulation and a high oxydative capacity of leg muscles and liver.

    Oxidative capacity of tissues contributing to thermogenesis in eider (Somateria mollissima) ducklings: changes associated with hatching (1988)

    Notizen: Summary 1. The development of liver and skeletal muscle oxidative capacities during hatching of the common eider (Somateria mollissima) in the Arctic has been investigated by monitoring tissue cytochrome c oxidase activity. 2. The specific activity of the liver enzyme did not change as the embryo underwent hatching, nor during subsequent growth of the duckling into adulthood. 3. Thigh muscle enzyme specific activity increased by a factor of 3.4 during the 24 h prehatching period, remained elevated for at least 48 h after hatching, and then returned to the embryonic (−24 h) level in adults. 4. Histochemically visualized NADH-tetrazolium reductase of a typical red thigh muscle, M. vastus lateralis, showed a distinct increase in activity as the hatching process progressed to completion. 5. Electron microscopy of sectioned M. vastus lateralis revealed a dramatic increase in the density of the myofibrillar structure (number of mitochondrial profiles per unit area), and in the surface area of mitochondrial crista membranes in the course of the 48 h interval from 1 day prehatching to 1 day after hatching. 6. The significance of these changes for the scaling of thermoregulatory heat generation in the newly hatched eider duckling is discussed.
