(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 ...
-
(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, ...
-
(Thesis, Doctor of Philosophy, 2005)This thesis set out to examine the soils, plants, lichens, invertebrates and common skinks along a gradient of habitat modification. This gradient was represented by ten study sites, of varying management histories, in a ...
-
(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, 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, 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. ...

(Conference or Workshop Item (Oral presentation), 16th Annual Colloquium of the Spatial Information Research Centre (SIRC 2004: A Spatio-temporal Workshop), 2004)The conservation status of New Zealand's indigenous grasslands has been assessed, as of September 2002, against an 1840 baseline, i.e., immediately before European settlement when New Zealand grasslands were essentially ... -
(Conference or Workshop Item (Oral presentation), 17th Annual Colloquium of the Spatial Information Research Centre (SIRC 2005: A Spatio-temporal Workshop), 2005)Reintroduction of threatened species to predator-free offshore islands has long been advocated in New Zealand as a prime management tool for conservation. They also provide a good experimental framework to investigate ... -
(Conference or Workshop Item (Oral presentation), 15th Annual Colloquium of the Spatial Information Research Centre (SIRC 2003: Land, Place and Space), 2003)Measurements of vegetation structure (the three dimensional placement of the vegetation biomass) and structural diversity (the number of vegetation layers present and the abundance of vegetation within them) are required ... -
(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, 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)Invasive plants modify ecosystem structure and function, which can result in an alternative novel state - jeopardising the ecosystems ecological value. The impact of invasive plants on communities, ecosystems or landscapes ...
-
(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 ...
-
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, Doctor of Philosophy, 2011)In many coastal areas increased anthropogenic influence has had a negative impact on the penetration of light through the water column, which may lead to increased periods of light limitation for subtidal macroalgae. This ...
-
(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, Master of Science, 2012)All light from the sun contains radiation in the ultraviolet (UV) range, wavelengths between 200 and 400 nm that may be harmful to living organisms. Exposure of plant tissues to UV-B radiation (200-400 nm) may result in ... -
(Thesis, Doctor of Philosophy, 2007)The aims of this study were to find endophytic brown algae in marine macroalgae from New Zealand, isolate them into culture and identify them using morphological as well as molecular markers, to study the prevalence of ...
-
(Thesis, Doctor of Philosophy, 1995)
-
(Thesis, Doctor of Philosophy, 2009)The flora of New Zealand has evolved largely in the absence of terrestrial mammals, the predominant frugivore guilds being birds and reptiles. The evolution of divergent fruit traits in New Zealand may be a consequence of ...
