Summary
Nitrogen and phosphorus modelled in freshwater eutrophication: The director’s cut
Most Life Cycle Impact Assessment (LCIA) methods to date estimate freshwater eutrophication impacts from phosphorus (P) only. There is a need to account for the…

Variability of Escherichia coli Concentrations in Rivers during Base-Flow Conditions in NZ
We compared the variability of E. coli concentrations in baseflow of 3 different-sized rivers in both summer and winter at the time scales of minutes,…

An event-based model of soil erosion and sediment transport at the catchment scale
Soil conservation over large areas is expensive and needs to be targeted to obtain maximum benefit for the least cost. In this paper, an event-based…
Journal Article
Stressor-response relationships and the prospective management of aquatic ecosystems
We set out a framework for interpreting S-R relationships in terms of functional forms, trajectories, thresholds and slopes. These characteristics convey information about resistance to…

Indirect Methods to Elucidate Water Flows and Contaminant Transfer Pathways through Meso-scale Catchments – a Review
We provide a critical review of indirect methods to elucidate water flows and contaminant transfer pathways through meso-scale catchments, as the proliferation of such methods…

Molecular Approaches to Identify Benign Denitrification in Shallow Groundwaters
We measured lower dissolved N2O and higher denitrifier genes abundance in the groundwater samples collected from reducing (anoxic) groundwaters sites, as compared with the groundwater…

Adaptation of water eutrophication indicators for EU environmental footprinting of NZ products
To address impacts on freshwater eutrophication, it is paramount that both N and P are accounted for. The current recommendation from the EC for Product…
