| Abstract |
Previous analyses of the life cycles and distributions of large antarctic copepods have concluded that competitive exclusion is the most important causal factor. It has been suggested that these species have asynchronous life cycles, their reproduction differing in time as a result of their interspecific interaction. I have analyzed these ideas by studying zooplankton samples collected by six expeditions in the Atlantic sector of the Antarctic ocean between 1963 and 1985. The results show no evidence of asynchronism among the species analyzed. An alternative hypothesis (independent life cycles), in which no competitive interactions are considered, is presented. |
