Resilience of microbial mats in Antarctic ponds to climate-relevant environmental disturbance
(The University of Waikato, 2021)Continental Antarctica is a cold desert, where the hydrologic system is dependent on melting of snow and ice. In a warming climate it is projected that there will be a significant change in precipitation, evaporation, cloud ... -
An investigation of microbial communities across two extreme geothermal gradients on Mt. Erebus, Victoria Land, Antarctica
(The University of Waikato, 2021)The geothermal fumaroles present on Mt. Erebus, Antarctica, are home to numerous unique and possibly endemic bacteria. The isolated nature of Mt. Erebus provides an opportunity to closely examine how geothermal physico-chemistry ... -
Origin of palaeo proglacial lake sediments in Taylor Valley, Antarctica
(The University of Waikato, 2005)The origin of carbonates found at three locations in the Taylor Valley and their association with different glacial advances is presented. Samples were collected from three locations through the Taylor Valley, specifically ... -
Microbial diversity in relation to human activity in historic areas of Ross Dependency, Antarctica
(The University of Waikato, 2003)The goal of this study was to undertake a relatively broad microbiological investigation at historic areas of Cape Evans and Ross Island. The two phylogenetically diverse targets were Bacillus anthracis, the causative agent ... -
An investigation of soil moisture associated with ephemeral streams, Wright Valley, Antarctica
(The University of Waikato, 2005)Ephemeral streams in Wright Valley, Antarctica, are fed by glacial melt and flow for between four and ten weeks annually. Hyporheic zones develop concomitantly with ephemeral stream channels. These zones are areas of ... -
Development and application of a method for U-Th dating of the Bonney Drift, Taylor Valley, Antarctica
(The University of Waikato, 1991)The lacustrine carbonates of the Bonney Drift, Taylor Valley, Antarctica were deposited in lakes proglacial to glaciers advancing through the valley, and now occur as lag and clasts in the glacial drift formed by the ... -
A Sedimentological and Micropaleontological Study of Quaternary Sections of Cores from the New Zealand Sector of the Southern Ocean
(The University of Waikato, 1998)The Southern Ocean lies between the Subtropical Front (STF) at about 45⁰S latitude and the continental landmass of Antarctica. It plays an important role in global climatic and oceanic circulation patterns, and is responsible ... -
Structure, light & temperature induced changes in the compound eyes of Antarctic crustaceans
(The University of Waikato, 1980)The structure of the photoreceptors of three different Antarctic crustaceans was investigated by light and electron microscopy. Special attention was paid to light and temperature induced changes of the normal, i.e. ... -
Volcanic geology and physical volcanology of Mount Morning, Antarctica
(The University of Waikato, 2006)Mount Morning is 70 km south of Ross Island and is part of the Cenozoic McMurdo Volcanic Group, which includes the presently active Erebus volcano. Few previous studies have investigated the mountain. The main exposures ... -
Microbial abundance and diversity surrounding mummified seals in Miers Valley, Antarctica
(The University of Waikato, 2004)The presence of a number of mummified seal carcasses have been reported in the Dry Valleys of Antarctica. The location of seal carcasses were observed up to 240km in-land, and approximately 1500m above sea level. The ... -
Use of Time Domain Reflectometry (TDR) to determine moisture and temperature regimes in Antarctic soils
(The University of Waikato, 2004)Antarctic soil moisture and temperature data are important as the soil climate influence. Antarctic ecosystems, and the data may provide information on climate change, and the effects of human activities on the Antarctic ... -
A study on molecular systematics of the Antarctic Bryum species and the development of microsatellite DNA markers in Bryum argenteum Hedw.
(The University of Waikato, 2000)The "silver" species Bryum subrotundifolium Jaeg. (Bryaceae) in Antarctica has undergone numerous taxonomic revisions. This research used the internal transcribed spacer (ITS) sequences of nuclear ribosomal DNA (nrDNA) to ... -
The fate and effects of JP-5 fuel in Antarctic soil: A controlled experiment at Scott Base, Antarctica
(The University of Waikato, 2002)Hydrocarbon contamination of Antarctic soils is evident in limited areas where accidental fuel spills have occurred, usually near scientific bases or field camps. To understand the short-term fate and effects of fuel spills ... -
Sedimentation in Antarctic proglacial lakes
(The University of Waikato, 1989)A variety of Antarctic lakes occur either as proglacial lakes to glaciers, or as detached lakes within an enclosed drainage system in the Dry Valleys of McMurdo Sound, Antarctica. Some of these are the evaporated remnants ... -
Soils and hydrology of Seabee Hook, Cape Hallett, Antarctica
(The University of Waikato, 2006)The soils and hydrology of Seabee Hook, Cape Hallett, Antarctica were investigated during the 2003-04 and 2004-05 summer periods. Seabee Hook is a low lying spit that has been built up by the deposition of material, from ... -
Antarctic bacteria and enzyme temperature optima
(The University of Waikato, 2003)The temperature optimum of enzyme activity, as recently described by Daniel et al. (2001), is thought to play a central role in the adaptation of an enzyme to its environmental temperature. The aim of this research was to ... -
Development of microsatellite markers for Antarctic Bryum Hedw. species
(The University of Waikato, 2002)The objective of this thesis was to isolate microsatellite markers using the Glenn (2001) method from the species Bryum argenteum so as to be able to study these markers in Antarctic populations of Bryum species. Microsatellite ... -
Biotreatability studies of oil-contaminated soils from Antarctica
(The University of Waikato, 2005)Human activity in Antarctica has resulted in accidental fuel spills on soils. These are broadly damaging to the Antarctic ecosystem, and expensive to clean up completely by physical removal, therefore, alternative remediation ... -
Genetic diversity and phylogeography of New Zealand and Antarctic arthropods
(The University of Waikato, 2005)Historical climatic and geological changes and ecological factors ( e.g. population size, dispersal abilities) are conducive to shaping genetic differentiation among natural populations. This thesis examines these issues ... -
Late Holocene cool climate episodes, recorded on Lake Bonney, an Antarctic amplifier lake
(The University of Waikato, 2005)Chemical, stable isotope and natural abundance radionuclide analysis of cores taken through sediments below Lake Bonney, Taylor Valley, Antarctica, show evidence of multiple episodes of flooding by meltwaters from Taylor ...
