A Taxonomic and Ecological Study of Periphytic Cyanobacteria in Kaituna River and Its Tributaries, Banks Peninsula, New Zealand.
(University of Canterbury. School of Biological Sciences, 2013)
Most of the detailed studies on periphyton in New Zealand rivers and streams have focused on diatoms. Despite the recent rise of interest in potentially toxic cyanobacterial mats, knowledge of the diversity and ecology ...
The invasion ecology of Didymosphenia geminata
(University of Canterbury. Biological Sciences, 2014)
Didymosphenia geminata (Didymo) is a nuisance, bloom forming, invasive freshwater algae. Through an ecological survey I examined habitat associations and effects, identifying bloom preferences for stable, low nutrient ...
Disentangling the effects of disturbance and habitat size on stream community structure
(University of Canterbury. School of Biological Sciences, 2011)
Our ability to predict community responses to environmental stress remains limited. To address this issue, I investigated how species abundance, community composition and food-web structure varied across abiotic gradients ...
Mechanisms and mitigation of food web change in stream ecosystems
(University of Canterbury. Biological Sciences, 2013)
Freshwater ecosystems reflect the condition of their surrounding landscape, and thus are particularly vulnerable to anthropogenic stressors associated with human land-use. One of the most prevalent stressors on stream ...
Chimpanzee (Pan troglodytes ellioti) ecology in a Nigerian montane forest
(University of Canterbury. Biological Sciences, 2012)
Due to high levels of exploitation, habitat loss and habitat degradation, Pan troglodytes has experienced such a significant population reduction over the past 20 to 30 years that it is now on the IUCN (International ...
