(Thesis, Master of Science, 2013)Alpine environments are highly variable with different selective pressures compared to lower altitude habitats. The alpine zone in New Zealand was formed in isolation and displays a range of unusual floral characteristics ...
-
(Thesis, Master of Science, 2001)The ecology of urban forest fragments is relatively understudied in New Zealand. The purpose of this study was to examine the ecology of the Dunedin Town Belt, especially with regards to regeneration, and to relate the ...
-
(Thesis, Master of Science, 2013)Understanding reproductive capabilities of individual species along altitudinal gradients is increasingly important in light of changes in habitat that are predicted with climate change. Alpine plants can be considered ... -
(Thesis, Doctor of Philosophy, 2013)The objective of this thesis was to improve our understanding of the processes and mechanisms underlying the successful invasion of Thymus vulgaris L. in Central Otago, New Zealand by carrying out aboveground and belowground ...

(Dissertation, Bachelor of Science with Honours, 1979)
-
(Thesis, Doctor of Philosophy, 2009)Plant-based defence mutualisms involve aspects of plant morphology that influence the performance of plant parasites, their natural enemies and trophic interactions. Leaf domatia, small indentations on the underside of ...
-
(Thesis, Doctor of Philosophy, 1996)Assembly rules represent the integrated action of species interactions leading to non-random patterns in the distributions of species niches in the combined niche space for a community or guild, i.e. to community structure. ...
-
(Thesis, Doctor of Philosophy, 2007)The intertidal red algal genus Porphyra is found on rocky shores worldwide. In the Northern Hemisphere the genus is well studied but there is a paucity of data on southern hemisphere Porphyra and even less on New Zealand ...
-
The ecology of Nothofagus menziesii in the Catlins ecological region, South-east Otago, New Zealand (Thesis, Doctor of Philosophy, 1985)In the Catlins Ecological Region of south-east Otago, New Zealand, Nothofagus menziesii is present as a continuous body of forest surrounded by other vegetation types lacking Nothofagus, and as a number of relatively small ...

(Thesis, Master of Science, 2007)
-
(Thesis, Master of Science, 2003)Historically there has been considerable debate over the origin of karaka (Corynocarpus laevigatus J.R. et G. Forst.) In contrast, the extent and importance of pre-historic arboriculture in New Zealand has received little ...

(Thesis, Master of Science, 2012)Alien plants cost the New Zealand economy over $1 billon per annum in lost revenue and control measures, and can modify native plant communities to the detriment of endemic biodiversity. Hieracium lepidulum has invaded ... -
(Thesis, Doctor of Philosophy, 2012)A major threat to biodiversity worldwide is human land-use change which increases habitat fragmentation and reduces landscape connectivity leading to species extinctions. For conservation biologists it is essential to ... -
(Thesis, Doctor of Philosophy, 2012)Large, isolated ‘specimen’ trees are a significant part of urban landscapes, yet their role in supporting wider biodiversity remains largely unexamined. The aims of this thesis were to examine how urban, isolated trees ...
-
(Thesis, Doctor of Philosophy, 2012)This thesis investigates the potential for a sand-dune plant, Ammophila arenaria (L.) Link (marram grass, European beach grass) to disperse and establish new colonies from pieces of its rhizome system. Such dispersal ... -
(Thesis, Master of Science, 2012)Ocean acidification is the lowering of oceanic pH that has resulted from the increase of CO2 in the atmosphere. pH is a dominant factor driving the dissociation of inorganic carbon in the ocean and because the pH is lowering, ...
