“…Of 150 insect species reported from the Antipodes Islands (ca. 49 • S) (Marris 2000), Coleoptera comprise only 25 species in 13 families. In comparison, the Snares Islands (48 • S) have a reported 25 species in 14 families; the Bounty Islands (ca.…”

“…In vagile taxa, such as the bryophytes and lichens, endemism tends to be low (acknowledging that further survey and taxonomic work might change the situation; Øvstedal & Gremmen 2001;Muñ oz et al 2004), while in insects, it is more variable. In islands close to continental or other landmasses genera and sometimes species are shared with what appears to be the source areas (Kuschel 1971;Vogel 1985;Marris 2000), while in more distant archipelagos, endemism is high and relationships are enigmatic. Indeed, the origin and closest relatives of many of the insect taxa from the South Indian Ocean Province Islands (Prince Edward Islands, Crozet Islands, Kerguelen Islands, Heard and McDonald Islands) remain a subject of vigorous contention, as they have been since the discovery of these species (see Jeannel 1964 for early discussion and Greve et al 2005 for recent partial review).…”

Antarctica and its surrounding islands lie at one extreme of global variation in diversity. Typically, these regions are characterized as being species poor and having simple food webs. Here, we show that terrestrial systems in the region are nonetheless characterized by substantial spatial and temporal variations at virtually all of the levels of the genealogical and ecological hierarchies which have been thoroughly investigated. Spatial variation at the individual and population levels has been documented in a variety of genetic studies, and in mosses it appears that UV-B radiation might be responsible for within-clump mutagenesis. At the species level, modern molecular methods have revealed considerable endemism of the Antarctic biota, questioning ideas that small organisms are likely to be ubiquitous and the taxa to which they belong species poor. At the biogeographic level, much of the relatively small ice-free area of Antarctica remains unsurveyed making analyses difficult. Nonetheless, it is clear that a major biogeographic discontinuity separates the Antarctic Peninsula and continental Antarctica, here named the 'Gressitt Line'. Across the Southern Ocean islands, patterns are clearer, and energy availability is an important correlate of indigenous and exotic species richness, while human visitor numbers explain much of the variation in the latter too. Temporal variation at the individual level has much to do with phenotypic plasticity, and considerable lifehistory and physiological plasticity seems to be a characteristic of Antarctic terrestrial species. Environmental unpredictability is an important driver of this trait and has significantly influenced life histories across the region and probably throughout much of the temperate Southern Hemisphere. Rapid climate change-related alterations in the range and abundance of several Antarctic and subAntarctic populations have taken place over the past several decades. In many sub-Antarctic locations, these have been exacerbated by direct and indirect effects of invasive alien species. Interactions between climate change and invasion seem set to become one of the most significant conservation problems in the Antarctic. We conclude that despite the substantial body of work on the terrestrial biodiversity of the Antarctic, investigations of interactions between hierarchical levels remain scarce. Moreover, little of the available information is being integrated into terrestrial conservation planning, which lags far behind in this region by comparison with most others.

“…The subantarctic flora and fauna are a mixture of endemics and taxa related to the closest continental areas (Morrone 1998). Here, we report for the first time phylogenetic evidence for a geographic connection with the Northern Hemisphere in a flightless insect, the staphylinid beetle Baeostethus chiltoni Broun (=Leptusa chiltoni (Broun)) recorded previously from the Antipodes and Campbell islands (Steel 1964;Marris 2000).…”

The placement of Leptusa chiltoni is restored to its original status as sole member of the genus Baeostethus. Baeostethus chiltoni is a subantarctic intertidal species that is present on the shores of Auckland, Antipodes, and Campbell islands. Baeostethus is concluded to be a member of Liparocephalini based on the absence of seta v on the adult mentum, several setae distributed only on the mesal surface and apex of the galea, and contiguous mesocoxal cavities. The phylogenetic relationships of Liparocephalini are investigated in the context of a previous study and Baeostethus is shown to be a sister taxon to Liparocephalus based on 12 synapomorphies (nine are unique). The majority of Liparocephalini are distributed along the coasts of the northern Pacific rim, some 9000 km away from B. chiltoni. Most are apterous, and with Baeostethus as a relatively derived member of the group, it is difficult to reconcile the biogeographic pattern based on a dispersal event from the northern Pacific to the Campbell Plateau. We argue that the trans-Pacific pattern in Liparocephalini is due to an older contiguous distribution along the coastal margins of Pangea. The data are supported by an alternative area cladogram derived from a rerooted tree, congruence with a Pacific rim pattern seen in intertidal Aegalitinae (Salpingidae), and the distribution and phylogeny of terrestrial Gymnusini (Aleocharinae).
