Emeritus - Freshwater Ecologist

Dr Dave Rowe gained his PhD at Stirling University and has more than 30 years experience with both native and introduced fish in NZ. He is responsible for a wide range of applied research and consultancy projects identifying factors that reduce native fish biodiversity in NZ rivers and lakes. Biosecurity is another speciality and he helped develop grass carp as a weed control agent, using this tool to rehabilitate NZ lakes via the eradication of both pest plants and introduced fish. More recently, research on the impacts of introduced fish on biodiversity and lake ecosystem functioning led to the development a NZ risk assessment model for fish introductions. Dave currently manages the Fish Group based in Hamilton. 

Marine Biologist

Dr. Kareen Schnabel is a taxonomist and systematist focussing her researach on New Zealand decapod crustaceans. She was the Collection Manager of the NIWA Invertebrate Collection between 2006 and 2015.
