  • Responses of salmonids to habitat changes

    Hicks, Brendan J.; Hall, James D.; Bisson, P. A.; Sedell, J. R. (1991)

    Book item
    University of Waikato

    Streams in western North America provide spawning and rearing habitats for several species of salmon and trout that are of substantial economic importance in the region. Timber that grows on lands through which these streams flow is also economically important, and its harvest can substantially change habitat conditions and aquatic production in salmonid streams. Undisturbed forests, the streams that flow through them, and the salmonid communities in these streams have intrinsic scientific, genetic, and cultural values in addition to their economic importance. The complex relations between salmonids and their physical environment, and the changes in these relations brought about by timber harvest, have been investigated extensively (see the bibliography by Macdonald et al. 1988). However, in spite of considerable evidence of profound changes in channel morphology and in light, temperature, and flow regimes associated with timber harvests, much uncertainty exists about the responses of salmonids to these changes.

  • The contructivist paradigm and some implications for science content and pedagogy

    Carr, Malcolm; Barker, Miles; Bell, Beverley; Biddulph, Fred; Jones, Alister; Kirkwood, Valda; Pearson, John; Symington, David (1997)

    Book item
    University of Waikato

    Through a comparison of the widely-held traditional view of science with the constructivist view of science, we argue that the constructivist view of the content of science has important implications for classroom teaching and learning. This alternative view of science concepts as human constructs, scrutinised by application of the rules of the game of science, raises many challenges for teachers. Reconceptualisation of teachers' views of the nature of science and of learning in science is important for a constructivist pedagogy. We argue here that open discussion of the 'rules of the game' of science would contribute to better learning in the classroom, since learners would be better equipped to change their existing concepts by knowing more about the nature of science itself.

  • Technology and science education

    Jones, Alister; Compton, Vicki (1997)

    Book item
    University of Waikato

    The incorporation of technology into the school curriculum is part of a worldwide trend in education. The way in which technology is incorporated depends on which country the reform is initiated in. The New Zealand Curriculum Framework (Ministry of Education, 1993a) includes science and technology as distinct learning areas. This chapter considers the view of technology expressed in both science in the New Zealand Curriculum (Ministry of Education, 1993b) and in Technology in the New Zealand Curriculum (Ministry of Education, 1995). The chapter is divided into four sections. Firstly, the concept of technology in the science curriculum is identified and discussed; secondly, the use of some types of technological application to enhance the learning of science outcomes is considered; thirdly, the technology curriculum itself is discussed in order to highlight the concept of technology underpinning this statement so that comparisons can be made with the concept employed in the science curriculum, and finally the introduction of technology outcomes by science teachers in a science environment is explored.

  • Electronics and control technology

    Forret, Michael (1997)

    Book item
    University of Waikato

    Until recently, there was no requirement to learn electronics and control technology in the New Zealand school curriculum. Apart from isolated pockets of teaching based on the enthusiasm of individual teachers, there is very little direct learning of electronics in New Zealand primary or secondary schools. The learning of electronics is located in tertiary vocational training programmes. Thus, few school students learn about electronics and few school teachers have experience in teaching it. Lack of experience with electronics (other than using its products) has contributed to a commonly held view of electronics as out of the control and intellectual grasp of the average person; the domain of the engineer, programmer and enthusiast with his or her special aptitude. This need not be true, but teachers' and parents' lack of experience with electronics is in danger of denying young learners access to the mainstream of modern technology.

  • Technology education in the New Zealand curriculum

    Jones, Alister (1997)

    Book item
    University of Waikato

    In this chapter, the way in which experience of existing school programmes influences teacher perceptions of technology education is discussed, and reasons for teaching technology are outlined. A relationship between technology and technology education is suggested and the structure of technology education in the New Zealand technology curriculum is described. A particular focus is the role of technological activities in technology education, and this is developed in the final section.

  • Towards an understanding of thermodynamic and kinetic controls on the formation of clay minerals from volcanic glass under various environmental conditions

    Hodder, A.P.W.; Naish, T.R.; Lowe, David J. (1996-01-01)

    Book item
    University of Waikato

    lmogolite is the kinetically and thermodynamically favoured weathering product from rhyolitic volcanic glass in the soil-forming environment. However, on thermodynamic grounds imogolite would also appear to be the favoured alteration product of rhyolitic glass deposited in the nearshore marine environment. On the basis that the rate of conversion of glass to clay minerals is a function of the solubility of the clay mineral, smectite is expected to be formed under mildly diagenetic conditions, and formed more rapidly than imogolite in soil. The derived activation energies for formation of imogolite from glass in soils are appropriate for a diffusion controlled reaction, and appear consistent with the diffusion of the tetrahedrally co-ordinated species Al[iv](OH)₂(H2Q)⁺. In the marine environment, however the mechanism for all reactions appear to be surface reaction control.

  • Lakes

    Lowe, David J.; Green, John D. (1992-01-01)

    Book item
    University of Waikato

    Lakes have always held an aesthetic fascination for people; they figure prominently in both art and literature and have even been endowed with spiritual qualities. For example, the nineteenth century American writer Henry D. Thoreau (1854) considered a lake to be 'the landscape's most beautiful and expressive feature. It is the earth's eye; looking into which the beholder measures the depth of his own nature'. More prosaically, lakes are also of considerable geomorphological interest as dynamic landfonns originating in varied and often complex ways.

  • The middle Waikato Basin and hills

    Selby, Michael J.; Lowe, David J. (1992-01-01)

    Book item
    University of Waikato

    The middle Waikato (or Hamilton) Basin is a roughly oval-shaped depression more than 80 km north to south and more than 40 km wide. The basin, except in the south, is almost completely surrounded by ranges up to 300 m high, broken by only a few gaps. In the south the basin floor rises gradually and merges with the dissected plateaux of the King Country.

  • Cloning of a family G xylanase gene (XYNB) from the extremely thermophilic bacterium Dictyoglomus thermophilum and action of the gene product on kraft pulp.

    Morris, DD; Gibbs, MD; Bergquist, Peter (1996)

    Book item
    The University of Auckland Library

    Xylanases can be grouped into two unrelated families, namely family F and family G. We report here the cloning of a family G xylanase gene (xynB) from the Dictyoglomus thermophilum strain Rt46B.1 and the characterisation of the expressed gene product (229B). Novel consensus-PCR and genomic-walking PCR techniques were used to isolate the xynB gene from Dictyoglomus thermophilum genomic DNA. Various 229B xylanases produced from xynB expression constructions had pH optima of 6.5, and temperature optimum ranges of between 70 and 85°C. The 229B xylanase was active on kraft pulp as shown by the release of reducing sugars.

  • Expression and Secretion of Bacterial Thermophilic Hemicellulases in Kluyveromyces lactis

    Walsh, DJ; Gibbs, MD; Bergquist, Peter (1998)

    Book item
    The University of Auckland Library

    The yeast Kluyveromyces lactis has been developed as a host for extracellular production of thermophilic hemicellulases employing expression vectors based on the 2μ-like plasmid pKD1 of Kluyveromyces drosophilarium, Α β-1,4-xylanase gene (xynA) from Dictyoglomus thermophilum strain Rt46B.1 was fused in-frame with a synthetic secretion signal derived from the K. lactis killer toxin and expressed under control of the Κ. lactis LAC4 (β-galactosidase) promoter. Correctly processed xylanase enzyme with full biological activity on Oat Spelt Xylan was secreted during shake-flask cultivation of Κ. lactis transformants. Yield was found to be dependent on the strain and the composition of the growth medium. The transcriptional activity of the LAC4 promoter dramatically affected mitotic stability of the expression vector under non-selective conditions. However, one isolate combined higher plasmid stability and good yield and has been employed for scaled-up production of XynA and other thermostable hemicellulases in chemostat culture. Similar results have been obtained for expression of a fusion of the xynA gene of Thermotoga strain FjSS3.B1 cloned into the same secretion vectors.

  • Geological Information in New Zealand

    Leaming, Elva (1999)

    Book item
    The University of Auckland Library

    New Zealand consists of two large is1ands--some 270,000 square kilometers in area--straddling a major crustal plate boundary. The present landscape is the highest part of a submerged subcontinent that broke away from Gondwana some 80 million years ago. To the northeast the Pacific oceanic plate is subducting westward, and to the southwest the Tasman seafloor is subducting eastward beneath the Campbell Plateau. These two subduction zones are linked through the transcurrent Alpine Fault. In the mid 19th Century two world-famous geologists contributed to the country's geological exploration. Hochstetter, from Austria, established a tradition of systematic geological mapping, and Hector, from Canada, founded the New Zealand Geological Survey. New Zealand's national geological organization, now the Institute of Geological and Nuclear Sciences (IGNS), continues to publish a broad spectrum of geological literature and maps. Its library holds the largest collection of geological literature pertaining to New Zealand. The six universities that teach geology and earth sciences each have library collections of a high standard. The University of Auckland Geology Collection is housed in the Science Library with an area that is a focal point for geological information and literature research.
