Summary: | INTRODUCTION The classical studies of Ege & Krogh (1914) and Krogh (1914, 1916) suggested that polar ectotherms would have an elevated metabolic rate (metabolic cold adaptation, MCA) relative to temperate ectotherms when exposed to the same temperature. Work by Scholander et al. (1953) and Wohlschlag (1960, 1964) suggested that cold-water fishes tended to have a relatively higher metabolic rate than temperate and warm-water species. The theory was later criticized (Holeton, 1973, 1974; Clarke, 1980, 1983, 1991, 1993; Hop & Graham, 1995), and several authors claimed that there was no evidence for MCA (Wells, 1986, 1987; Bushnell et al., 1994; Ste ensen et al., 1994; Clarke & Johnston, 1999). A potential problem in comparative studies of MCA to date, is that the fish fauna of the Southern Ocean consist to a large part of notothenioids (Perciformes). Thus most comparative studies between polar, temperate and tropical species have related to ecology and only a few studies have concerned |
