Ecology:  Nutrient consequences of salmon spread

Peter D. Moore1

The end of a salmon run is a pretty gloomy affair — mature fish, having expended their final resources of energy on reproduction, wearily donate what remains of their bodies to the recycling processes of the aquatic ecosystem. Ecologists, lacking sentimentality, have asked whether this input of fish biomass to the headwaters of a stream is a significant import of key elements, such as nitrogen and phosphorus, to the area.
