(The University of Waikato, 2000)Deforestation and conversion to pasture of over 50% of land area has affected the water quality, physical habitat, and fish and benthic invertebrate communities of New Zealand streams, but the impact of land use change on ... -
Evaluating techniques for sampling stream crayfish (paranephrops planifrons)
(RSNZ Publishing, 1997)We evaluated several capture and analysis techniques for estimating abundance and size structure of freshwater crayfish (Paranephrops planifrons) (koura) from a forested North Island, New Zealand stream to provide a ... -
Growth and population dynamics of crayfish Paranephrops planifrons in streams within native forest and pastoral land uses
(RSNZ Publishing, 2002-11)Population dynamics of crayfish (Paranephrops planifrons White) in streams draining native forest and pastoral catchments, Waikato, New Zealand, were investigated from September 1996 to July 1998. Crayfish densities were ... -
New Zealand stream crayfish: Functional omnivores but trophic predators?
(Wiley-Blackwell, 2001)1. The feeding ecology of the crayfish Paranephrops planifrons in streams draining catchments in native forest and pastoral land was investigated using analyses of both stomach contents and stable isotopes of carbon and ...
