Article: Anadromous alewives (Alosa pseudoharengus) contribute marine-derived nutrients to coastal stream food webs.(Report)

Introduction

Biota can play a central role in regulating the flux of energy and nutrients across ecosystem boundaries (Vanni 2002). One noteworthy example is Pacific salmon (Oncorhynchus spp.) that transport nutrients from marine to freshwater systems in the Pacific Northwest as a consequence of their anadromous life history (Naiman et al. 2002; Schindler et al. 2003; Thomas et al. 2003).
