Kelp forests are characterized by high biodiversity and productivity, and the cycling of kelp-produced carbon is a vital process in this ecosystem. Although bacteria are assumed to play a major role ...
We experimentally investigated the response of phytoplankton and understory macroalgae to canopies of giant kelp, Macrocystis pyrifera, by following changes in their biomass and net primary productio...
The nutrient climate on the inner shelf off southern California changed markedly across the 1976–1977 North Pacific climate regime shift. With respect to giant kelp (Macrocystis pyrifera) canopies of...
The effects of aMacrocystis pyriferaforest on currents and turbulence were investigated in a controlled laboratory setting using a dynamically matched 1/25-scale model. Two kelp configurations with su...
To determine the relative importance of different sources of nitrate to the annual nitrogen needs of the giant kelpMacrocystis pyrifera,we measured ambient nitrate concentrations at a kelp forest for ...
