A study of California quail in New Zealand with particular reference to population ecology
(Lincoln College, University of Canterbury, 1966)
California quail, probably Lophortyx californicus brunnescens, were first liberated in New Zealand in 1962. The species’ geographical range and habitat types are described.
A general account then follows of local diurnal ...
The influence of population and weeds, on the yield of fodder beet
(Lincoln College, University of Canterbury, 1964)
To achieve maximum crop yield, factors influencing growth must be identified, evaluated and limiting ones overcome. Limits to growth will be revealed by studying the crop in terms of its physiology, ecology and particularly ...
Flow in xylem
(Lincoln College, University of Canterbury, 1968)
Solutions of either ³²P or ⁴²K were drawn through segments of green and dormant poplar by applying a vacuum pressure at the upper end. Uptake was shown to consist of two fractions, the first passing through the stem via ...
The autecology of sweet brier (Rosa rubiginosa L.)
(Lincoln College, University of Canterbury, 1966)
Sweet brier is of particular interest in New Zealand, because it occurs widely as an unwanted plant in extensively grazed tussock grasslands of the eastern South Island. Since the control of the rabbit it has rapidly ...
Studies on the aerobic bacterial flora of a New Zealand tussock grassland soil
(Lincoln College, University of Canterbury, 1962)
The work described herein was best divided into 4 rather distinct parts. All are concerned with the aerobic bacterial flora of a single New Zealand grassland soil whose characteristics are described. The 4 parts deal ...
The biology and ecology of Coccinella undecimpunctata undecimpunctata L.
(Lincoln College, University of Canterbury, 1966)
The majority of Coccinellid ladybirds are beneficial to man because of their predacious nature. In 1874 Coccinella undecimpunctata Linneaus, was introduced into New Zealand, (Dumbleton 1936), as one of the first attempts ...
A chronosequence of soils and vegetation near the Franz Josef Glacier
(Lincoln College, University of Canterbury, 1963)
The recent rapid retreat of the Franz Josef Glacier in South Westland has produced extensive tracts of morainic debris, subsequently fashioned into a series of terraces of varying ages by the meandering Waiho River. These ...
Nitrogen fixation by root nodules of Coriaria
(Lincoln College, University of Canterbury, 1968)
Coriaria is the most widespread and vigorous genus of nodulated, nitrogen fixing plants in the native flora of New Zealand. The following study is concerned with the impact that Coriaria, and in particular C. arborea, has ...
A chronosequence of soils near the Franz Josef Glacier
(Lincoln College, University of Canterbury, 1968)
One method of studying the effects of Time as a Soil Forming Factor is the recognition and investigation of a Chronosequence, wherein four of the five Soil Forming
Factors are kept constant or ineffectively varying. Thus, ...
Forms of soil phosphate in some genetically-related New Zealand soils
(Lincoln College, University of Canterbury, 1965)
Phosphate fertilisation of soils is essential for the maintenance of high levels of agricultural production. This is especially true in New Zealand, where repeated topdressings with superphosphate are essential for the ...
