Roles and Responsibilities

Major leader for Ecology

I am a generalist.  My teaching, research and postgraduate supervision is very diverse but with two main themes: aquatic systems, and quantitative methods.  My PhD thesis (Victoria University, Wellington) was on the biogeography and systematics of New Zealand caddisflies.  That involved discovering and describing new species of these aquatic insects but also led to research in methods for phylogenetic analysis, biogeographic theory, and also the ecology of the stream communities that caddisflies are part of.  More recently I have branched out to study lake ecosystems (particularly deep stratified lakes) and fisheries modelling.

Project Title: Understanding the 'dead zone' in Lake Namunamu

Lake Namunamu is a small lake in central North Island hill country formed by a landslide 2,000 years ago. The lake is very deep for its size which results in some unusual behaviour. It is strongly stratified (warmer at the top than the bottom), with no oxygen in the bottom waters, for most of the year. That would be expected in a lake with excessive nutrients but Namunamu is completely surrounded by forest and has no obvious source of nutrients. There is a lot of biological production in the lake but it is all hidden from view, concentrated at about 5 metres deep. At that depth there is a very dense bloom of a dinoflagellate (a type of single-celled 'plant') and just below that is an even denser concentration of a green-sulphur bacterium. These bacteria are photosynthetic like plants but they don't produce oxygen as a by-product. They use hydrogen sulphide, release sulphur, and they can only live in the absence of oxygen. Similar bacteria can be found in the 'dead zones' that are forming in our seas at an alarming rate, driven by excess nutrients from the land and made worse by global warming. A lake like Namunamu can be a more convenient place to study and understand these processes.
