Rafting in Antarctic Collembola
- T. C. Hawes, M. R. Worland, J. Bale, P. Convey
- Biology
- 24 August 2007
Darwin was an early exponent of the importance of ‘occasional means of dispersal’ in accounting for the present-day distribution of plants and animals. This study examined the implications of capture… Expand
Plasticity and superplasticity in the acclimation potential of the Antarctic mite Halozetes belgicae (Michael)
- T. C. Hawes, J. Bale, M. R. Worland, P. Convey
- Biology, Medicine
- Journal of Experimental Biology
- 15 February 2007
SUMMARY The plasticity of an organism's phenotype may vary spatially and temporally, and across levels of physiological organisation. Given the adaptive value of plasticity in heterogeneous… Expand
Freezing in the Antarctic limpet, Nacella concinna.
- T. C. Hawes, M. R. Worland, J. Bale
- Biology, Medicine
- Cryobiology
- 1 August 2010
The process of organismal freezing in the Antarctic limpet, Nacella concinna, is complicated by molluscan biology. Internal ice formation is, in particular, mediated by two factors: (a) the provision… Expand
Plasticity in arthropod cryotypes
- T. C. Hawes, J. Bale
- Biology, Medicine
- Journal of Experimental Biology
- 1 August 2007
SUMMARY Low-temperature acclimation and acclimatization produce phenotypic changes in arthropods at multiple levels of biological organization from the molecular to the behavioural. The role and… Expand
Habitat temperature and the temporal scaling of cold hardening in the high Arctic collembolan, Hypogastrura tullbergi (Schäffer)
- T. C. Hawes, C. Couldridge, J. Bale, M. R. Worland, P. Convey
- Biology
- 1 October 2006
Abstract 1. Cold tolerance is a fundamental adaptation of insects to high latitudes. Flexibility in the cold hardening process, in turn, provides a useful indicator of the extent to which polar… Expand
Aerial dispersal of springtails on the Antarctic Peninsula: implications for local distribution and demography
- T. C. Hawes, M. R. Worland, P. Convey, J. Bale
- Biology
- 1 March 2007
Aerial dispersal has been frequently proposed as a potential mechanism by which polar terrestrial arthropods are transported to, and settle the ice free habitats of Antarctica, but to date there has… Expand
Haplotype diversity in the Antarctic springtail Gressittacantha terranova at fine spatial scales - a Holocene twist to a Pliocene tale
- T. C. Hawes, G. Torricelli, M. Stevens
- Biology
- 1 December 2010
The mitochondrial COI gene of the Antarctic springtail, Gressittacantha terranova, was sequenced across a polar coastal landscape at Terra Nova Bay, northern Victoria Land. Samples from two… Expand
Aeolian fallout on recently deglaciated terrain in the high Arctic
- T. C. Hawes
- Biology
- Polar Biology
- 1 February 2008
In the absence of autochthonous inputs, it has been hypothesised that winds operate as an important vector for the nutritional subsidisation of pre-vegetative sites on deglaciated terrain (the… Expand
Physiological constraints on the life cycle and distribution of the Antarctic fairy shrimp Branchinecta gaini
- T. C. Hawes, M. R. Worland, J. Bale
- Biology
- Polar Biology
- 5 August 2008
Maturation to adulthood and successful reproduction in the Antarctic fairy shrimp, Branchinectagaini, must be completed within a physiologically challenging temporal window of ca. 2.5 months in the… Expand
Origins and dispersal of the Antarctic fairy shrimp
- T. C. Hawes
- Biology
- 1 October 2009
Passive dispersal has traditionally formed a fundamental component of biogeographical theories of the origin of the fauna that occupy the ice-free habitats of mainland Antarctica. But in the context… Expand
