  • An ecological study of Chinese privet (Ligustrum sinense Lour.) in the Waikato Region

    Grove, E.; Clarkson, Bruce D. (2005)
    Chinese privet (Ligustrum sinense) has naturalised across the Waikato region invading lowland native forest and wetland habitat. This shrub has the ability to form a dense canopy or subcanopy and appears to exclude other ...
  • Electrofishing survey of the Manawatu, Whanganui, and Mokau rivers and Lake Rotorangi, Petea River

    Hicks, Brendan J.; Bell, Dudley G. (Department of Biological Sciences, University of Waikato, 2003)
    We used New Zealand’s first successful electrofishing boat to survey fish in three large North Island rivers and in Lake Rotorangi, hydro-electric impoundment on the Patea River. The primary objective of the fishing was ...
  • Evaluating remote sensing data classification techniques for mapping freshwater habitats: Trial application in the Tongariro River delta, Lake Taupo

    Ashraf, Muhammad Salman; Brabyn, Lars; Hicks, Brendan J. (Centre for Biodiversity and Ecology Research, The University of Waikato, 2008-07)
    The overall goal of this study is to evaluate different classification techniques that can be applied to multi-source satellite remote sensing data to map different freshwater habitat zones. The Tongariro River delta at ...
  • The feasibility of using otolith microchemistry to trace movements of rainbow trout and common smelt in lakes Rotoiti and Rotorua

    Riceman, Matthew Sean; Hicks, Brendan J. (Centre for Biodiversity and Ecology Research, The University of Waikato, 2007-05)
    Otolith microchemistry can be used to determine the natal origins of fish. Our feasibility study using single water samples has determined that the water chemistry around Lakes Rotorua and Rotoiti, have different elemental ...
  • Field guide for didymo DNA sample collection

    Hicks, Brendan J.; Cary, S. Craig; Barnett, Catherine Margaret Eleanor (Centre for Biodiversity and Ecology Research, The University of Waikato, 2007-11)
    This protocol is designed for work in two-person teams for both safety and to maximise sample integrity.
  • Fish biosurveillance by genetic methods: a feasibility study

    Knox, Matthew Andrew; Hicks, Brendan J.; Banks, Jonathan C.; Hogg, Ian D. (Centre for Biodiversity and Ecology Research, School of Science & Engineering, University of Waikato, 2008)
    We evaluated the possibility of isolating DNA from environmental samples to detect and identify invasive fish species based on variation in the sequences for mitochondrial gene region. Goldfish CO1 DNA was successfully ...
  • Fish populations of Lake Ngaroto, Waikato, and fish passage at the outlet weir.

    Hicks, Brendan J.; Reynolds, Gavin B.; Jamieson, Paul M.; Laboyrie, J. Lee (Centre Biodiversity and Ecology Research, 2001)
    1.Lake Ngaroto has a diverse fauna of native and introduced fish. It is largest of the Waipa lakes, is hypertrophic (i.e., has very high concentrations of plant nutrients), and is highly productive for this reason. 2.In ...
  • Genetic identification of fish

    Banks, Jonathan C.; Hicks, Brendan J.; Lobb, Richard; Blair, Jennifer Marie (Centre for Biodiversity and Ecology Research, The University of Waikato, 2010-11)
    Our report shows that the straightforward extraction of DNA and amplification of appropriate genes can identify fish that are difficult to identify unequivocally from morphology alone. Three examples show that these ...
  • Indigenous vegetation types of Hamilton Ecological District

    Clarkson, Bruce D.; Clarkson, Beverley R.; Downs, Theresa M. (2007)
    The following descriptions of indigenous vegetation types and lists of the most characteristic species have been compiled for the major landform units of the Hamilton Ecological District, which lies within the Waikato ...
  • Influence of human pressures on large river structure and function

    Collier, Kevin J.; Clapcott, Joanne E.; Young, Roger G. (2009)
    A large river study was conducted as part of the Cross Departmental Research Pool (CDRP) ecological integrity project to (i) provide an overview of the macroinvertebrate faunas of large rivers, including those in deep-water ...
  • An investigation to determine origin: age and otolith chemistry of a brown bullhead catfish (Ameiurus nebulosus) found at Okawa Bay, Lake Rotoiti

    Blair, Jennifer Marie; Hicks, Brendan J. (2009)
    Some time between 10 and 15 January 2009, a brown bullhead catfish(Ameiurus nebulosus) was found washed up on the shore of Okawa Bay, Lake Rotoiti. The elemental signature of the otolith was measured using laser ablation ...
  • Is there a lack of science resources and specialists for kaiako at Kura reo o Waikato?

    Hopkins, Aareka (Centre for Biodiversity and Ecology Research, The University of Waikato, 2010-08)
    The New Zealand debates on culture and science education for Maaori are grounded in the concern for the under-achievement of tauira in science. In 1995, a lack of subject experts, specialists and resources to implement the ...
  • Issues facing Southland’s wetlands— recommendations for future management

    Campbell, David I.; Clarkson, Beverley R.; Clarkson, Bruce D. (2003)
    This report summarises our experiences and recommendations from a weeklong series of fieldtrips and workshops focused on Southland’s wetlands. Our major recommendations are: • Priorities must be developed for wetland ...
  • Key ecological sites of Hamilton City: Volume 1

    Cornes, Toni S.; Thomson, Rachel Elizabeth; Clarkson, Bruce D. (Centre for Biodiversity and Ecology Research, The University of Waikato, 2012-05)
    Ecological sites of significance previously identified in 2000 were reviewed in 2011. Natural vegetation in areas acquired by the city since 2000 was also surveyed to identify any new key sites. In total seventy key sites ...
