Allometry, biomass and litter decomposition of the New Zealand mangrove Avicennia marina var. australasica
(Auckland University of Technology, 2014)Accurate estimates for biomass pools and fluxes are the key for assessing the potential of vegetation to counteract anthropogenic carbon emissions. However, such data are laborious to retrieve and still missing for many ... -
The Ecophysiology of the New Zealand Mangrove, Avicennia marina (Forssk.) Vierh. subsp. australasica (Walp.) J. Everett
(Auckland University of Technology, 2019)The availability of water is an important environmental factor determining plant growth, survival, and distribution globally. From a physiological viewpoint, non-structural carbohydrates (NSCs) are necessary for plants to ... -
Effect of Nutrients and Salinity on Growth of Temperate Mangroves (Avicennia marina var australasica) in Northern New Zealand
(Auckland University of Technology, 2019)Estuarine environmental conditions in New Zealand have changed greatly due to human catchment activity (e.g., deforestation, intensive agricultural activity, and urbanisation). These factors have led to additional accretion ... -
The Effects of Seabirds, Rats, and Ecosystem Restoration on Invertebrate Food Webs
(Auckland University of Technology, 2016)Burrowing seabirds that nest on islands transfer nutrients from the sea, disturb the soil through burrowing, damage tree foliage when landing, and thereby modify the surface litter. One of the greatest effects seabirds may ... -
Epidemiology and Physiological Impact of Aerial Phytophthora pluvialis in New Zealand and Oregon Forest Systems
(Auckland University of Technology, 2019)Forest health is threatened by invasive plant-infecting fungi and fungal-like organisms, whose frequency has increased with international trade in recent decades. While planted forests are particularly vulnerable to invasive ... -
In Situ Leaf Growth Measurements Using Digital Image Analysis
(Auckland University of Technology, 2019)Plant growth is a broad topic that is of interest in many different research fields from the basics of plant functioning, to agricultural research, and ecology. In this thesis, I first distinguish different aspects of plant ... -
Nor any drop to drink: Water relations of the mangrove avicennia marina (Forssk.) vierh
(Auckland University of Technology, 2018)Essential players within the planet’s water cycle, plants are themselves sensitive to ongoing global change. Future shifts in water availability are predicted to change the face of the earth’s forests. In the last decades ... -
The Role of Honeybee Pollination in Native New Zealand Plants
(Auckland University of Technology, 2021)Honeybees (Apis mellifera) fill a keystone role in the pollination of many plant species. Studies have found that honeybees visit native New Zealand plants, however, with exception to Metrosideros excelsa, little data on ... -
Understanding Warming Effects on Vegetation Through Geothermal Hotspots: A Case Study of the Wairakei-Tauhara Geothermal Field, Taupo, New Zealand
(Auckland University of Technology, 2017)Understanding and predicting warming effects on vegetation is a key challenge of the 21st century. To date, warming experiments have been limited to isolated laboratory studies, which have been criticised as too small-scale ...
