51. Measurements of the viscosity of blood and plasmas at various temperatures and shear rates in Antarctic notothenioids, zoarcids, channichthyids and a New Zealand notothenioid [K012_1988_1989_NZ_1]
The viscosity of blood and plasma was measured from the Antarctic notothenioids Pagothenia borchgrevinki, Trematomus bernacchii, T. centronotus and Dissostichus mawsoni, from the Antarctic zoarcid ...


52. Metabolic and biochemical consequences of niche specialization of Antarctic fish - heat stressed proteins, metabolite levels, nucleotide ratios, neurotransmitters, muscle buffering capacity, blood erythrocytes [K012_1992_1995_NZ_1]
Antarctic notothenioid fishes have radiated to fill a range of ecological niches, forming an assemblage of over a hundred closely related species. Some groups have developed extreme specializations ...


53. Miniature end plate currents recorded from Pagothenia borchgrevinki muscle at different temperatures and measurements of the function of the oculomotor (eye movement response) control system [K012_1981_1982_NZ_1]
Miniature end plate currents (MEPC) were recorded from fish muscle of Pagothenia borchgrevinki to test the hypothesis that the high proportion of unsaturated lipids will result in increased membrane ...


54. Physiological control of the heart and pH balance in Antarctic fish: An adaptation to cold temperatures [K012_1986_1987_NZ_1]
Changes in temperature are thought to affect the relative contributions of the excitatory adrenergic and inhibitory parasympathetic nerves to the vertebrate heart. Investigations of the heart function ...


55. Temperature selection, locomotion and feeding behaviour of Antarctic fish [K012_1983_1984_NZ_3]
To test the ability of Antarctic fishes to perceive and react to temperature differences, a temperature gradient from -1.8?C to +5.4?C was set up in a trough and fish were monitored to see which part ...


56. The effects of pH and drugs on miniature end plate current decay in extraocular muscles of the Antarctic fish Pagothenia borchgrevinki [K012_1982_1983_NZ_2]
Previous experiments indicated that miniature end plate currents (MEPCs) from extraocular muscles of Antarctic fish decay significantly faster than MEPCs from New Zealand temperate fish. As the Antarctic ...


57. The effects of temperature and pH on collegen denaturation at fish skin contractions in Antarctic fish [K012_1988_1989_NZ_4]
Measurements of fish skin contraction as a function of temperature and pH and the effects of temperature on denaturation of collagen was investigated by incubating strips of skin from several notothenioid ...


58. The effects of temperature on conduction of the nervous impulse and transmission of the impulse from nerve to muscle in two Antarctic fish and an isopod [K012_1977_1978_NZ_1]
The pattern of cold adaptation in the nervous system of Antarctic fish, with particular attention to the effects of temperature changes on conduction of the nervous impulse and on transmission of ...


59. The histological development of blood cells and identification of erythropoietin in the red blooded Antarctic notothenioid species [K012_1994_1995_NZ_1]
A joint program with the Italian program investigated erythropoesis (formation of red blood cells) and red cell turn over in the red blooded Antarctic fishes. A range of fish tissues was collected ...


60. The neural biology of Antarctic fish: Measurements of the neural activity from fish semicircular canals in response to head movement [K012_1983_1984_NZ_1]
The input and outputs of a well defined reflex pathway (the vestibulo-ocular reflex - VOR) was described in Antarctic fish to assess the mechanisms of neural cold adaptation at low temperatures. The ...


61. The respiratory physiology of Antarctic fish: resting metabolism, dermal respiration and haemoglobin denaturation investigations [K012_1984_1985_NZ_3]
Metabolic studies were made on 4 common species of notothenioids; Pagothenia borchgrevinki, Trematomus bernacchii, T. centronotus, T. hansoni and on one zoarcid species Rhigophila dearborni. Fish ...


62. The viscosity of the endolymph in Pagothenia borchgrevinki and Dissostichus mawsoni to assess the relative degrees of cold compensation at different stages in the vestibulo-ocular reflex arc [K012_1988_1989_NZ_3]
Endolymph (inner ear fluid) from the semicircular canals was collected from Pagothenia borchgrevinki and Dissostichus mawsoni by dissecting the mid brain to expose the intact vestibular apparatus. ...


63. Tissue collection for molecular and morphological phylogenetics of Antarctic fishes [K012_1989_1992_NZ_2]
Tissue was collected for molecular analysis of evolutionary relationships in the notothenioids. Material from 10 notothenioids and 2 zoarcids was collected and analysed.


64. Measurements of the energy requirements of adelie penguins (Pygoscelis adeliae) by analysis of blood samples for the turnover rate of injected radioactive water and salts and from analysis of gut contents [K121_1984_1987_NZ_1]
The metabolic rate and energy requirements of penguins was determined by measuring the turnover rates of radioactive body water and salts. Individual birds were banded, weighed and injected with radio-active ...
