Spatiotemporal variability in primary producer growth rates is a fundamental aspect of community structure. Understanding drivers of these patterns and their response to climate variability and change are ongoing challenges. Nutrient and light limitations often are invoked as proximate drivers of these patterns, but many other environmental and biological factors vary across spatial and temporal scales. In temperate rocky inte...

The aims of the survey were to update the national overview of pesticides in New Zealand's groundwater systems, to investigate temporal variation in pesticide concentrations between surveys, and to identify environmental factors associated with pesticide contamination of groundwater. Thirty‐one wells (19%) tested...
