A lush canopy is a defining feature of most of the planet's forests. But canopy-forming species can be particularly vulnerable to disturbances and environmental change. So the question is: What is a f...
Sea otters have long been recognized as a classic example of a keystone species, a dominant predator that maintains the balance of kelp forest ecosystems by controlling populations of sea urchins, whi...
Satellite imagery shows that the area covered by kelp forests off the coast of Northern California has dropped by more than 95%, with just a few small, isolated patches of the bull kelp remaining. Spe...
Ethereal, swaying pillars of kelp along California's coasts grow up through the water, to form a dense surface canopy of thick fronds that provide homes for numerous marine creatures.Scientists have s...
Certain species serve as the foundations of their ecosystems. Scientists are increasingly interested in ecological stability -- the factors that allow an ecosystem to withstand pressures and perturbat...
Plants need nutrients to grow. So scientists were surprised to learn that giant kelp maintains its impressive growth rates year-round, even in summer and early fall when ocean currents along the Calif...
An ecosystem is made up of species, populations, communities, and a network of communities across a region.A team led by NSF-funded researchers at the University of California-Santa Barbara (UCSB) has...
We explored the use of stable nitrogen (N) isotope analysis to assess trophic position of consumers in two marine ecosystems: the kelp forests of southern California and a coral atoll in the tropical ...
Forests of the giant kelp Macrocystis pyrifera found on coastal rocky reefs lack the large reservoirs for nutrient storage found in many terrestrial environments. Supporting their high year-round grow...
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...
Masticatory pressure caused by chewing with molars was measured using a multiple-point sheet sensor. The sensor system is useful to directly indicate masticatory force and contact area with various su...
Southern California Edison Co. (SCE) is required to build a 300 hectare (150 acre) artificial reef for the purpose of mitigating the impacts of the San Onofre Nuclear Generating Station on nearby ke...
El Niiios are large-scale, climatic anomalies that originate in the tropical Pacific and affect oceanographic and atmospheric conditions globally. Along the west coast of North America, where El Nif...
