Joy and Death (2001): Control of freshwater fish and crayfish community structure in Taranaki, New Zealand: dams, diadromy or habitat structure?

Joy M. K.; Death R. G. 2001. Control of freshwater fish and crayfish community structure in Taranaki, New Zealand: dams, diadromy or habitat structure? Freshwater Biology 46: 417-429.

This paper investigates the relationship between fish and crayfish communities and environmental variables at a number of scales from proximal to landscape on the Taranaki ring plain. The analysis showed elevation, distance from the coast and dams were the strongest predictors of fish and crayfish assemblages. Dams had greater impacts at lower elevation and landscape scale variables proved more important than proximal habitat variables in structuring fish communities.
