Magnification of Secondary Production by Kelp Detritus in Coastal Marine Ecosystems
- D. O. Duggins, C. Simenstad, J. Estes
- Environmental Science, Medicine
- Science
- 14 July 1989
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 of… Expand
Sea Otters and Kelp Forests in Alaska: Generality and Variation in a Community Ecological Paradigm
- J. Estes, D. O. Duggins
- Biology
- 1 February 1995
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
- D. O. Duggins, J. E. Eckman, Amy T. Sewell
- Biology
- 30 October 1990
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 shading… Expand
Is kelp detritus a good food for suspension feeders? Effects of kelp species, age and secondary metabolites
- D. O. Duggins, J. E. Eckman
- Biology
- 2 June 1997
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 serpulid… Expand
Geographic variation in polyphenolic levels of Northeastern Pacific kelps and rockweeds
- K. L. Van Alstyne, J. J. McCarthy III, C. L. Hustead, D. O. Duggins
- Biology
- 9 March 1999
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. We… Expand
Ecology of under story kelp environments. I. Effects of kelps on flow and particle transport near the bottom
- J. E. Eckman, D. O. Duggins, Amy T. Sewell
- Biology
- 22 August 1989
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
FATTY ACID SIGNATURES DIFFERENTIATE MARINE MACROPHYTES AT ORDINAL AND FAMILY RANKS 1
- Awe Galloway, K. Britton-Simmons, D. O. Duggins, P. W. Gabrielson, M. Brett
- Biology, Medicine
- Journal of phycology
- 1 August 2012
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 fatty… Expand
Starfish Predation and the Creation of Mosaic Patterns in a Kelp‐Dominated Community
- D. O. Duggins
- Biology
- 1 December 1983
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 rapid… Expand
Addressing assumptions: variation in stable isotopes and fatty acids of marine macrophytes can confound conclusions of food web studies
- M. Dethier, Elizabeth A. Sosik, A. E. Galloway, D. O. Duggins, C. Simenstad
- Biology
- 25 March 2013
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 isotopes… Expand
Population, morphometric and biomechanical studies of three understory kelps along a hydrodynamic gradient
- D. O. Duggins, J. E. Eckman, C. Siddon, T. Klinger
- Biology
- 31 December 2003
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 flow… Expand
