Trophic Relationships and Diet of Consumers in Temperate Kelp Forest and Coral Reef Ecosystems
Temperate Kelp Forest Coral Reef Ecosystems
2015/7/16
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 ...
Multiple Sources and Forms of Nitrogen Sustain Year-Round Kelp Growth on the Inner Continental Shelf of the Santa Barbara Channel
Nitrogen Sustain Year-Round Kelp Growth Santa Barbara Channel
2015/7/16
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...
Partitioning of primary production among giant kelp (Macrocystis pyrifera), understory macroalgae, and phytoplankton on a temperate reef
giant kelp understory macroalgae phytoplankton
2014/4/4
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 response of giant kelp (Macrocystis pyrifera) in southern California to low-frequency climate forcing
giant kelp southern California
2014/4/17
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...
Currents and turbulence within a kelp forest (Macrocystis pyrifera): Insights from a dynamically scaled laboratory model
Currents and turbulence a kelp forest Insights a dynamically scaled
2014/4/17
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...
Transplanting Giant Kelp (Macrocystis pyrifera) onto Artificial Reefs: The San Clemente Reef Mitigation Project
Macrocystis pyrifera kelp transplant Artificial Reefs
2009/5/6
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 Nino 1997-1998: Large-Scale Patterns of Disturbance and Recovery in Giant Kelp Forests
Macrocystis pyrifera kelp weather El Nino
2009/5/6
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...
Photosynthetic Response of Arctic Kelp Forests to Stratospheric Ozone Depletion

Photosynthetic Response of Arctic Kelp Forests to Stratospheric Ozone Depletion.
Experimental assessment of the effects of shade on an intertidal kelp: Do phytoplankton blooms inhibit growth of open-coast macroalgae?
Experimental assessment an intertidal kelp
2014/4/17
Benthic primary producer abundance and satellite-derived chlorophyll concentrations are strongly negatively
correlated along the Oregon and Northern California coast, suggesting an antagonistic inter...
Internal Wave Attenuation by Coastal Kelp Stands
Internal Wave Coastal Kelp Stands low frequencies
2009/1/20
Coastal kelp stands are a unique physical environment having high drag distributed throughout the water column. Temperature records from locations at increasing distances into the kelp show a damping ...
Physical pathways and utilization of nitrate supply to the giant kelp, Macrocystis pyrifera
Physical pathways utilization of nitrate supply giant kelp, Macrocystis pyrifera
2014/4/18
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 ...
Modulation of wave forces on kelp canopies by alongshore currents
Modulation of wave forces on kelp canopies alongshore currents
2014/5/20
The predominant view of the canopy-forming kelp’s mechanical response to water motion is that they sway passively under waves such that they are only rarely stretched out in flow, which reduces r...
Evolution of kelp morphology in response to local physical factors: the effect of small-scale water flow on nutrient uptake, growth, and speciation in the southern sea palm, Eisenia arborea
morphology growth, and speciation
2015/11/12
Evolution of kelp morphology in response to local physical factors: the effect of small-scale water flow on nutrient uptake, growth, and speciation in the southern sea palm, Eisenia arborea。
A study of water velocities near subtidal kelp fronds, relative to the motion of the kelp itself, is described. The dynamic model developed by Utter and Denny (1996) is used to develop a quantitative ...
