Productivity of kelp forests, sans the iconic kelp
kelp forests environmental change ecosystem forest canopy
2021/8/5
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 keep remaining California kelp forests alive(图)
Sea otters keep remaining California kelp forests alive
2021/4/9
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...
Collapse of Northern California kelp forests will be hard to reverse(图)
Collapse Northern California kelp forests hard to reverse
2021/3/19
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...
Researchers explore potential for kelp to relieve ocean acidification(图)

2020/12/11
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...
Giant kelp gives Southern California marine ecosystems a strong foundation(图)
Giant kelp Southern California marine ecosystems strong foundation
2020/2/20
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...
In search of an undersea kelp forest's missing nitrogen(图)
undersea kelp forest missing nitrogen
2019/10/28
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...
What keeps ocean kelp forest ecosystems stable?(图)
keeps stable ocean kelp forest ecosystems
2019/10/30
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...
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...
