51. Lipid transport, lipid metabolism and cold adaptation in Antarctic notothenioid fish [K058_2005_2008_NZ_1]
Fish species of the suborder Notothenioidei are morphologically distinct in that they lack a swim bladder. To compensate, high levels of tissue lipids aid in maintaining buoyancy. The lipids also ...


52. Measurement and comparison of miniature end plate currents between notothenioid Antarctic fish species [K012_1998_2000_NZ_2]
To determine if cold-adaptation of neuromuscular ion currents, as reported for Mini End Plate Currents (MEPCs) of one Antarctic fish species, Pagothenia borchgrevinki is a widespread feature of ther ...


53. Measurement of the effects of pH and temperature on the oxygen binding properties (oxygen affinity) and ATP concentrations in whole blood of Antarctic fish [K012_1982_1983_NZ_1]
Many Antarctic fishes have taken advantage of the combination of low oxygen requirements and high availability of oxygen by reducing the number of erythrocytes and the amount of intracellular haemoglobin. ...


54. Measurement of the vibrations the sensory neurons of the anterior lateral line can detect in the Antarctic fish Pagothenia borchgrevinki in relation to prey detection [K012_1985_1986_NZ_2]
A study of predator-prey interaction was focussed into an investigation of non-visual sensory interaction between Pagothenia borchgrevinki and its prey. Recordings were made from sensory neurons of ...


55. Measurements of factors affecting the timing of nest relief in Adelie penguins at Cape Bird [K121_1986_1987_NZ_1]
The timing of nest relief is crucial to the nesting success of adelie penguins. Experiments were conducted to test whether the physiological conditions of the female will determine how long she stays ...


56. Measurements of metabolic rate, osmotic pressure and blood volume of pycnogonids from Antarctica [K057_1985_1986_NZ_2]
Several individuals of several species of pycnogonids (sea spiders) were obtained from the aquarium at McMurdo Station. Measurements of metabolic rate, osmotic pressure and blood volume was determined ...


57. Measurements of the caridac, hematocrit and haemoglobin concentration recovery rates from exercise and in response to cardioregulatory drugs of Pagothenia borchgrevinki, T. bernacchii and Rhigophila dearborni [K012_1988_1989_NZ_2]
Electrocardiograms were recorded for Pagothenia borchgrevinki, T. bernacchii and Rhigophila dearborni while the fish were immobilised by artificial ventilation of the gills by rapid water flow over ...


58. 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 ...


59. Measurements of the quantal content in neuromuscular transmission of the Antarctic fish Pagothenia borchgrevinki - end plate potential recordings from muscle fibres [K012_1984_1985_NZ_1]
The Antarctic fish Pagothenia borchgrevinki was captured from near Scott Base and used to measure the quantal content in neuromuscular transmission of Antarctic fish. The amount of neurotransmitter ...


60. 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 ...


61. 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 ...


62. Metabolic changes of notothenioid fish in relation to nutritional status [K058_2007_2008_NZ_1]
Individuals of Trematomus bernacchii and Pagothenia borchgrevinki were captured and used in an experiment to understand metabolic changes, especially pertaining to the lipid transport system (lipoproteins) ...


63. Meterological Data from AWS, Darwin Glacier (Brown Hills) [K702_2004_2012_NZ_1]
Location: S79 50.113, E159 19.122 AWS/environemntal logging station was installed in the central valley (S 79º 50.113" E 159º 19.122") between Lake Wilson and Diamond Glacier in the Darwin Glacier ...


64. 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 ...
