    The climate is changing – as it always has! But now, changes are taking place at an unprecedented pace, and we already now have temperatures that are as high as they were during the Holocene maximum five thousand years ago (Hansen et al. 2006). These changes are particularly pronounced in the Arctic, and in the future they are modelled to be even more pronounced here due to a number of feed-back mechanisms (Kattsov et al. 2005). The increased melting of snow and sea ice is of particular importance, since snow and ice reflect about 75 pct. of the incoming solar...

  5. Aerial kleptoparasitism by the Magnificent Frigatebird: Host size selection, social dominance, and aerodynamic constraints
    (pp. 17-38)
    Carlos A. Valle, Tjitte de Vries and Cecilia Hernández

    Frigatebirds are seabirds adapted for aerial life that forage and feed on the wing (Nelson 1975) and have evolved a variety of foraging methods including the highly specialized aerial kleptoparasitism (Nelson 1975, Diamond 1975, Brockmann and Barnard 1979, Barnard 1984). Aerial kleptoparasitism, or food stealing from other seabird species or from conspecifics, involves an aerial attack and an active chase and harassment of hosts (victims) that force them to regurgitate, while frigatebirds retrieve the meal usually from the air and occasionally from the water surface or from the ground (Osornoet al. 1992, Valle 1986). Sex and age-class differences in...

  6. Colour and size variation in the Northern Fulmar Fulmarus glacialis on Bear Island, Svalbard.
    (pp. 39-58)
    Jan Andries van Franeker and Robert Luttik

    Bear Island, or Bjørnøya, is situated in the Barents Sea at 74°30’N and 19°00’E, approximately 450 km north of the Norwegian Nordkapp and 230 km south of Spitsbergen. The island is triangular in shape, measures ± 207×15 km, and is uninhabited except for a Norwegian radio station on its northern coast. The northern half is rather flat, lies ± 20 to 50 m above sea level and holds many lakes. To the southeast of this plain there is a 536 m high mountain called Miseryfjellet. Further south several other mountains gradually rise up to 440 m above sea level. Most...

  7. Barnacle goose Branta leucopsis survey on Nordenskiöldkysten, west Spitsbergen 1975–2007: breeding in relation to carrying capacity and predator impact
    (pp. 59-84)
    Rudolf H. Drent and Jouke Prop

    The barnacle gooseBranta leucopsisbreeds in three discrete flyways: Greenland (wintering in Ireland and westernmost Scotland), the Svalbard archipelago (mainly on the largest island, Spitsbergen, wintering on the Solway Firth, UK) and the Russian arctic (wintering mainly in coastal Germany and the Netherlands). The population breeding on Spitsbergen is the smallest of the three and experienced a dramatic low of only 300 birds in 1948 but assisted by conservation measures (closure of hunting, establishment of refuges at the main wintering site and sanctuaries at the breeding sites) has recovered since (Owen & Black 1999). The leading question now is to...

  8. The little bird and the big whale. 1986–2006
    (pp. 85-102)
    Louwrens Hacquebord

    Four centuries ago England and the Netherlands began whaling in the waters around Spitsbergen (Conway 1906; De Jong 1983; Jackson 1978; Hacquebord 1984a; Stora 1987; Bruijn 1988). The whaling trade commenced in 1611 and lasted more than two hundred years (fig. 1, fig. 2), with its success being highly dependent on ice and weather conditions (Hacquebord 1984b). By around 1850, whaling in Spitsbergen had led to the complete removal of the bowhead whale (Balaena mysticetus) from the marine ecosystem (Hacquebord & Leinenga 1994). The extermination of the bowhead whale is a good example of the way that natural resources in polar...

  9. 1986–2006: Twenty years of research on baleen whales in the Antarctic
    (pp. 103-118)
    Kees Lankester

    Ko de Korte made his first voyage to the Antarctic in the summer of 1985/86. In the following two decades he frequented the Southern Ocean and he saw many large whales. Scientific research on the large whales in those twenty years has offered more insight in their whereabouts and behaviour. This contribution to the Ko-special of the Circumpolar Journal reviews the progress in the debate on and understanding of the science on baleen whales in Antarctic waters covering the past twenty years.

    Ko’s first summer in the Antarctic coincided with the season that the global moratorium on commercial whaling came...

  10. Testate amoebae in a changing Arctic
    (pp. 119-132)
    Louis Beyens, Pieter Ledeganck and Ivan Nijs

    Polar worlds are characterized by some degree of isolation from the lower latitudes. Maybe this is one of the attractions they have for some breeds of scientists who long to work in remote landscapes that captivate the mind. If we take a look at Dr. Ko de Korte’s polar career, it is obvious that he belongs to those who explored their scientific questions by means of fieldwork in the purest sense of the word. The development of communication technology has partly diminished this isolation. With increased accessibility, more scientists, tourists and adventurers are visiting the polar regions. This augmented entering...

  11. A Passion for the Pole
    (pp. 133-146)
    Ko de Korte

    How could one describe the attraction of the Pole region? What is it that often makes you long to be there, how can you explain to others the mixture of nostalgia and happiness that you feel when you think of it? The feelings I refer to here are comparable to the emotions which are sometimes aroused by music, poetry and the visual arts. They belong to the field of aesthetics and even sensuality. As I search for words to make others understand how it is that the Pole area has drawn me to it to such an extent for the...
