Contrasting phylogeographical patterns for springtails reflect different evolutionary histories between the Antarctic Peninsula and continental Antarctica
(Blackwell Publishing, 2009)Aim: We examined the genetic structure among populations and regions for the springtails Cryptopygus antarcticus antarcticus and Gomphiocephalus hodgsoni (Collembola) to identify potential historical refugia and subsequent ... -
The corophiid amphipods of Tauranga Harbour, New Zealand: evidence of an Australian crustacean invader
(Springer, 2002)Using morphological and molecular techniques we examined the corophiid amphipods in the Waimapu Estuary, Tauranga Harbour in the North Island of New Zealand. Based on morphology we identified two New Zealand endemic species, ... -
Distinct migratory and non-migratory ecotypes of an endemic New Zealand eleotrid (Gobiomorphus cotidianus) – implications for incipient speciation in island freshwater fish species
(BioMed Central (online), 2008-02)Background: Many postglacial lakes contain fish species with distinct ecomorphs. Similar evolutionary scenarios might be acting on evolutionarily young fish communities in lakes of remote islands. One process that drives ... -
Distribution and abiotic influences on hypolithic microbial communities in an Antarctic Dry Valley
(Springer, 2010)The Miers Valley within the McMurdo Dry Valleys of Antarctica supports abundant quartz and marble substrates for hypolithons—microbial colonists on the underside of these translucent rocks. Three physically distinct ... -
Environmental influences on Adelie penguin breeding schedules, endocrinology, and chick survival
(Elsevier, 2011)To understand how the social and physical environment influences behaviour, reproduction and survival, studies of underlying hormonal processes are crucial; in particular, interactions between stress and reproductive ...
