Developing an optimal method for producing a tearless onion
(Lincoln University, 2008)
People experience the irritating tearing and burning sensation of lachrymatory factor (LF, propanthial S-oxide) when cutting or chopping onion bulbs. LF is produced by lachrymatory factor synthase (LFS) specifically from ...
Habitat selection and breeding ecology of the endangered Chatham Island oystercatcher (Haematopus chathamensis)
The Chatham Island oystercatcher (Haematopus chathamensis) is an endangered shorebird endemic to the Chatham Islands, New Zealand. In the late 1980s the population was estimated at less than 110 individuals and was feared ...
Phaeomoniella chlamydospora: potential inoculum sources in the grapevine propagation process
(Lincoln University, 2004)
Phaeomoniella chlamydospora is a recently described fungal pathogen that infects grapevines causing Petri disease, which is observed externally as a general decline. The objective of this research programme was to identify ...
Enhancing the biological control of leafrollers (Lepidoptera: Tortricidae) using floral resource subsidies in an organic vineyard in Marlborough, New Zealand
(Lincoln University, 2005)
In this thesis, experiments were conducted in both the laboratory and the field to determine whether the provision of floral resources to Dolichogenidea tasmanica Cameron (Hymenoptera: Braconidae) could enhance the biological ...
Urban biotopes: the typical and unique habitats of city environments and their natural analogues
(Wickliffe Press, 2000)
This paper reports on an investigation of Christchurch biotopes, based on sampling uniform areas where species were recorded by composition, abundance, and features of the physical environment. Seven biotopes were identified ...
Propagule size and the relative success of exotic ungulate and bird introductions to New Zealand
(The University of Chicago Press for The American Society of Naturalists, 2001-06)
We investigated factors affecting the success of 14 species of ungulates introduced to New Zealand around 1851-1926. The 11 successful species had a shorter maximum life span and were introduced in greater numbers than the ...
Kiwi forego vision in the guidance of their nocturnal activities
(Public Library of Science, 2007-02)
Background: In vision, there is a trade-off between sensitivity and resolution, and any eye which maximises information gain at low light levels needs to be large. This imposes exacting constraints upon vision in nocturnal ...
Examination of Trichoderma phylogenies derived from ribosomal DNA sequence data
(Cambridge University Press, 2000-01)
Ribosomal DNA sequences were assessed for their usefulness in distinguishing among Trichoderma isolates and for their robustness in resolving their phylogenetic relationships. DNA sequences from the D2 region of the 28S ...
