Abstract
The springtail Gomphiocephalus hodgsoni Arthropoda Collembola has been the focus of extensive ecophysiological and molecular genetic work and is now arguably the most wellstudied of the continental Antarctic springtails Here we further the ecophysiological catalogue of this species First we provide experimental data on G hodgsoni from one summer season at Cape Bird Ross Sea Region examining dispersal ability and desiccation tolerance Next we expand an existing metabolic rate dataset that encompasses individual metabolic rate measurements across both temporal and spatial scales in southern Victoria Land adding an additional season of metabolic rate measurements taken at a cooler drier continental location Garwood Valley Our data show that some G hodgsoni individuals can survive at least ten days of suspension on the surface of both fresh and sea water This coupled with the presence of G hodgsoni specimens in air and pitfall traps suggests that dispersal over local scales ie metres is possible for this species Our metabolic data show that different populations within the same Antarctic region have different average metabolic rates at both temporal and spatial scales indicating that distinct populations may respond differently to environmental variables We suggest that G hodgsoni maintains a flexible life history strategy that allows its ecophysiological responses to be dependent on local environmental conditions Accordingly there may be no ‘typical’ response to environmental changes—a factor that should be considered in both future ecophysiological work and conservation approachesWe thank Laurie Beth Connell and two anonymous reviewers for their constructive comments on an earlier version of the manuscript We are also grateful to Antarctica New Zealand for their logistical support Funding for this project was provided by a New Zealand Tertiary Education Commission Top Achiever Doctoral Scholarship and a Sir Robin Irvine Doctoral Scholarship to AM with the latter also supporting PC’s fieldwork and by a New Zealand Foundation for Research Science and Technology Grant UOWX0710 to IH This paper forms a contribution to SCAR’s Evolution and Biodiversity in the Antarctic EBA Antarctica New Zealand’s Latitudinal Gradient Project LGP and British Antarctic Survey’s Polar Science for Planet Earth PSPE research programmes
