The history of biogeography is briefly reviewed in relation to the dispersal/vicariance controversy. A cladistic analysis of known good dispersers, the admiral butterflies (Bassaris and Vanessa), provides a basis to assess the relative roles of dispersal and vicariance in generating geographic distribution patterns. Cladistic parsimony analyses of geographic distribution and phylogenetic data for Gondwanic and circum-antarctic taxa are used to appraise some of the varied views on the biogeographic classification and relationships of New Zealand. The new panbiogeographic approach to New Zealand's biogeographic classification is outlined and its conceptual links with geology reviewed. New models and explanations for two classic problems in New Zealand biogeography, the origin of the Chatham Islands biota and the mid-South Island glacial gap, are presented. These are based on track and cladistic analyses.

“…The contention stems largely from a long-standing debate about the origins of terrestrial Antarctic biotas. In particular, much controversy swirls around whether the biotas of the continent are relatively recent colonists or older palaeoendemics, and the extent of the relationships between the continental biota and those found on the more northerly maritime Antarctic and sub-Antarctic islands [9][10][11][12][13][14][15].…”

Mite dispersal among the Southern Ocean Islands and Antarctica before the last glacial maximum

et al. 2010

It has long been maintained that the majority of terrestrial Antarctic species are relatively recent, post last glacial maximum, arrivals with perhaps a few microbial or protozoan taxa being substantially older. Recent studies have questioned this 'recolonization hypothesis', though the range of taxa examined has been limited. Here, we present the first large-scale study for mites, one of two dominant terrestrial arthropod groups in the region. Specifically, we provide a broad-scale molecular phylogeny of a biologically significant group of ameronothroid mites from across the maritime and sub-Antarctic regions. Applying different dating approaches, we show that divergences among the ameronothroid mite genera Podacarus, Alaskozetes and Halozetes significantly predate the Pleistocene and provide evidence of independent dispersals across the Antarctic Polar Front. Our data add to a growing body of evidence demonstrating that many taxa have survived glaciation of the Antarctic continent and the sub-Antarctic islands. Moreover, they also provide evidence of a relatively uncommon trend of dispersals from islands to continental mainlands. Within the ameronothroid mites, two distinct clades with specific habitat preferences (marine intertidal versus terrestrial/supralittoral) exist, supporting a model of within-habitat speciation rather than colonization from marine refugia to terrestrial habitats. The present results provide additional impetus for a search for terrestrial refugia in an area previously thought to have lacked ice-free ground during glacial maxima.

“…Another common delineation of the region includes the area south of the Antarctic convergence, which is an important climatic boundary between air and water masses, and is also used as the approximate boundary of the Southern Ocean that surrounds the Antarctic continent. However, for the purposes of this paper the former definition of the Antarctic is used, while the term sub-Antarctic is ascribed to the islands in the Insulantarctic biogeographical province and the islands south of New Zealand (Udvardy, 1987).…”

Geotourism has achieved considerable prominence since the early 1990s as a means of conserving geological and geomorphological heritage. However, most accounts of the effects of geotourism are at a site-specific level while interpretation tends to focus on deep geological time rather than the Anthropocene. This restriction in consideration of time and space has meant that the broader effects of geotourism-related travel throughout the tourism system have been ignored, along with the potential role of climate change in affecting geosites and attractions. These issues are discussed with respect to the paradoxes of geotourism in polar regions with the polar cryospheric environment being both threatened by climate change yet simultaneously becoming more accessible and attractive to tourists. The article concludes that, like any form of tourism, geotourism needs to be understood within the broader context of tourism and physical systems rather than in isolation in order to fully access its contribution to geoconservation.

The biogeographical realm Antarctica: A proposal

Abstract: This paper diseusses the plaee and ex te nt of the Antaretie Realm within a biogeographie system of the world. Within this realm, I propose four biogeographical provinees (Maudlandia, Marielandia, Insulantaretiea and Neozealandia) and give brief justifieations for this proposal.
