58. Estimates of growth rates of lichen from photographs of lichen thalli on the Mt Falconer summit and ridge and the Rhone Bench (above Lake Bonney), Taylor Valley [K024_1980_2008_NZ_1]
A small number of lichen thalli on Mt Falconer summit and ridge and the Rhone Bench (above Lake Bonney) were marked and photographed during the 80-81 field season. These plants were refound over subsequent ...


59. Vegetation survey in a proposed long-term monitoring site at Castle Rock [K024_1996_1997_NZ_1]
The site, near Castle Rock was delineated in a previous season by another investigator. The area was carefully searched and plants located, identified and as necessary, collected for herbarium and ...


60. An ecological study of Bird Pond at Cape Bird: water parameters, population density and identification plants and animals [K014_1970_1971_NZ_3]
A seasonal ecological study was carried out at Bird Pond, Cape Bird. At weekly intervals the water temperature, depth, conductivity, pH and light were recorded, water samples were analysed for oxygen, ...


61. Biological survey of the Balleny Islands [K407_2000_2001_NZ_1]
