Rafting in Antarctic Collembola
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 captureExpand

Plasticity and superplasticity in the acclimation potential of the Antarctic mite Halozetes belgicae (Michael)
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 heterogeneousExpand

Freezing in the Antarctic limpet, Nacella concinna.
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 provisionExpand

Plasticity in arthropod cryotypes
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 andExpand

Habitat temperature and the temporal scaling of cold hardening in the high Arctic collembolan, Hypogastrura tullbergi (Schäffer)
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 polarExpand

Aerial dispersal of springtails on the Antarctic Peninsula: implications for local distribution and demography
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 hasExpand

Haplotype diversity in the Antarctic springtail Gressittacantha terranova at fine spatial scales - a Holocene twist to a Pliocene tale
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 twoExpand

Aeolian fallout on recently deglaciated terrain in the high Arctic
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 (theExpand

Physiological constraints on the life cycle and distribution of the Antarctic fairy shrimp Branchinecta gaini
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 theExpand

Origins and dispersal of the Antarctic fairy shrimp
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 contextExpand
