Magnification of Secondary Production by Kelp Detritus in Coastal Marine Ecosystems
Kelps are highly productive seaweeds found along most temperate latitude coastlines, but the fate and importance of kelp production to nearshore ecosystems are largely unknown. The trophic role ofExpand

Sea Otters and Kelp Forests in Alaska: Generality and Variation in a Community Ecological Paradigm
Multiscale patterns of spatial and temporal variation in density and popu- lation structure were used to evaluate the generality of a three-trophic-level cascade among sea otters (Enhydra lutris),Expand

Ecology of understory kelp environments. II, Effects of kelps on recruitment of benthic invertebrates
Previous studies demonstrated that understory kelps altered rates of mass and particulate transport beneath kelp canopies. This study examined the implications of these physical effects, plus shadingExpand

Is kelp detritus a good food for suspension feeders? Effects of kelp species, age and secondary metabolites
Abstract The food quality of detrital particles derived from three species of kelps was evaluated in a laboratory feeding experiment utilizing two species of suspension feeders, the serpulidExpand

Geographic variation in polyphenolic levels of Northeastern Pacific kelps and rockweeds
Abstract Brown algal polyphenolic compounds are secondary metabolites whose functions may include protecting plants from pathogens or damage by UV radiation, and deterring feeding by herbivores. WeExpand

Ecology of under story kelp environments. I. Effects of kelps on flow and particle transport near the bottom
Abstract Because of their likely ecological importance, the effects of understory kelps on fluid and paniculate transport near the bottom were assessed in waters of the San Juan Archipelago,Expand

Primary productivity by plants and algae is the fundamental source of energy in virtually all food webs. Furthermore, photosynthetic organisms are the sole source for ω‐3 and ω‐6 essential fattyExpand

Starfish Predation and the Creation of Mosaic Patterns in a Kelp‐Dominated Community
Subtidal kelps in Torch Bay, Alaska, resemble a mosaic of discrete algal patch types. This pattern reflects the patchy distribution of herbivorous sea urchins (Strongylocentrotus spp.) and the rapidExpand

Addressing assumptions: variation in stable isotopes and fatty acids of marine macrophytes can confound conclusions of food web studies
Studies that use biomarkers to elucidate consumer diets often must assume that these signa- tures are relatively invariant in space and time. We tested this assumption for multiple stable isotopesExpand

Population, morphometric and biomechanical studies of three understory kelps along a hydrodynamic gradient
Kelps (benthic algae in the order Laminariales) live in a highly dynamic fluid environ- ment, and exhibit many adaptations to meet the challenges imposed by hydrodynamic forces. We examined flowExpand
