Earthquake impacts in old-growth Nothofagus forests in New Zealand
(Opulus Press, 2001-06)
Six stands located on different land forms in mixed old-growth Nothofagus forests in the Matiri Valley (northwest of South Island, New Zealand) were sampled to examine the effects of two recent large earthquakes on tree ...
The role of competition and introduction effort in the success of passeriform birds introduced to New Zealand
(The University of Chicago Press for The American Society of Naturalists, 1997-05)
The finding that passeriform birds introduced to the islands of Hawaii and Saint Helena were more likely to successfully invade when fewer other introduced species were present has been interpreted as strong support for ...
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 ...
Insect performance and host-plant stress: a review from a biological control perspective
(CSIRO Entomology, 2003)
Three hypotheses predict how insect herbivores perform on stressed host plants. The plant stress hypothesis (PSH) predicts improved insect performance on stressed hosts. The plant vigour hypothesis (PVH) predicts that ...
Tree regeneration in a New Zealand rain forest influenced by disturbance and drainage interactions
(Opulus Press, 2005-08)
Question: Does canopy tree regeneration response to different large disturbances vary with soil drainage? Location: Old-growth conifer (Dacrydium and Dacrycarpus), angiosperm (Nothofagus and Weinmannia) rain forest, Mount ...
Small-scale species richness in forest canopy gaps: the role of niche limitation versus the size of the species pool
(Opulus Press, 1998-06)
The form of the relationship between local species richness and the number of species in the surrounding region can be used as a test between competing theories of community structure. For 32 canopy gaps in New Zealand ...
