Recent environmental legislation and institutional structural change has altered the network of human-environment relationships in the SouthIsland high country. The current tiering of responsabilities has promoted conflicts about policy goals
In this paper, morphological characteristics of longitudinal profiles of rivers are analyzed in relation to mathematical functions in the SouthIsland of New Zealand, and their regional characteristics are examined in relation to geomorphological

Bird Island in Algoa Bay supports a breeding colony of South African (Cape) fur seals. This is the easternmost extreme of their breeding range and is likely to be the most environmentally marginal of the existing fur seal colonies. Climatic
conditions on Bird Island are analysed and issues of heat stroke and starvation examined. It is shown that modest (2°C) increases in average summer temperatures would greatly increase the number of potentially lethal hot days. - (AJC)
Plate boundary tectonics and oceanic island geomorphology in The geomorphology of plate boundaries and active continental margins.
This paper illustrates how studies of the geomorphology of oceanic islands can contribute to the understanding of nearby plate boundaries. For this purpose, an oceanic island is defined as one within an ocean basin. Case studies are given of three
contrasting situations : a) islands behind a subduction zone (the Law islands behind the Tonga trench in the Pacific| b) an island oceanwards of a trench (Christmas island near the Sunda trench in the Indian Ocean| c) islands scattered each side of a spreading
The biogeography of the macrolepidoptera of south-eastern Polynesia
The distributions and affinities of the macrolepidopteran taxa known from south-eastern Polynesia are investigated and contrasted with various geological hypotheses for the origin of the islands. A colonialist interpretation, long distance dispersal
into a westering assemblage of small islands much as seen today, appears to be most probable.
Geomorphology of South Atlantic Volcanic Islands. Part I: the Tristan da Cunha group
Volcanoes of the Tristan Group have varied physiography resulting from the interplay of repeated volcanic eruptions, coastal erosion and fluvial erosion. The geomorphic histories of the islands are more complicated than was described in earlier

Mapping actual and predicted perceptions of wilderness enables the impact of resource use activities upon wilderness to be modelled. The Heaphry Road in the Norhwest portion of New Zealand's SouthIsland is used to evaluate the effects
Comparing the effects of acidic deposition on the chemistry of small streams in the SouthIsland of New Zealand with those in the Fichtelgebirge, F.R.G.

Simple linear regression is used to interpret erosion rates on two shore platforms from the Kaikoura Peninsula, SouthIsland, New Zealand. Using this analysis it is suggested that measured rates could be viewed as representatives of populations
Third World meets First World in the West Coast region of the SouthIsland : possum hunting and the role of social forestry in indigenous forest management

This paper descibes the characteristics of, and outlines the most likely origins for, three forms of unusual patterned ground observed in the Falkland Islands, South Atlantic. The features here described are not products of frost-related processes
Island uplift and lithospheric flexure : observations and cautions from the South Pacific in Neotectonics and morphotectonics.
Here the A. A provide new information from instrumented surveys of geomorphological features in the Society Islands, the North-west Tuamotu Archipelago and the Southern Cook Islands. The flexure models are also more generally evaluated in the light
of improved chronologies for island volcanism and the radiometric dating of emergent limestones and thus in terms of the likely geomorphological history of these islands.
This paper examines features of drainage and stream channel form and process on the mountainous volcanic island of Kadavu in the humid tropical South Pacific, and interprets the findings in relation to island environmental characteristics
increasing numbers of cyclones in the South Pacific and human vegetation disturbance on Kadavu are considered.
