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 ...
Declining plant species richness in the tussock grasslands of Canterbury and Otago, South Island, New Zealand
(New Zealand Ecological Society, 2001)
We studied vegetation change on 142 permanently marked transects spread throughout tussock grasslands of Otago and Canterbury, in areas subject to both pastoral and conservation management. The transects were established ...
Population age structure and recent Dracophyllum spread on subantarctic Campbell Island
(New Zealand Ecological Society, 2005)
Mid to late 20th century expansion of Dracophyllum scrub into tussock grassland on subantarctic Campbell Island has been attributed to the collective effects of global warming, cessation of farming in 1931, and continued ...
Light environments occupied by conifer and angiosperm seedlings in a New Zealand podocarp-broadleaved forest
(New Zealand Ecological Society, 2009)
Interaction between conifers and angiosperms in New Zealand’s podocarp–broadleaved forests is a topic of enduring interest. We aimed to determine if the often discontinuous regeneration of the podocarps Dacrydium cupressinum ...
Burrowing seabirds affect forest regeneration, Rangatira Island, Chatham Islands, New Zealand
(New Zealand Ecological Society, 2007)
The forests of Rangatira Island (218 ha) in the Chatham Islands are a critical breeding site for a number of rare and threatened forest bird species, but are also home to more than three million seabirds, which could significantly ...
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 ...
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 ...
Plant invasions downunder
This poster considers plant naturalisations in New Zealand from the late nineteenth century to year 2000. Notes on which species naturalised earliest and what species spread the furthest are given also.
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 ...
