A cross-ecosystem comparison of the strength of trophic cascades
Although trophic cascades (indirect effects of predators on plants via herbivores) occur in a wide variety of food webs, the magnitudes of their effects are often quite variable. We compared theExpand
MOSAIC PATTERNS OF THERMAL STRESS IN THE ROCKY INTERTIDAL ZONE: IMPLICATIONS FOR CLIMATE CHANGE
We explicitly quantified spatial and temporal patterns in the body temperature of an ecologically important species of intertidal invertebrate, the mussel Mytilus californianus, along the majority ofExpand
Climate Change and Latitudinal Patterns of Intertidal Thermal Stress
TLDR
Climate change may not lead to a poleward shift in the distribution of intertidal organisms, but instead will likely cause localized extinctions at a series of “hot spots” at several northern sites. Expand
WHAT DETERMINES THE STRENGTH OF A TROPHIC CASCADE
TLDR
It is found that high system productivity and low species diversity do not consistently generate larger trophic cascades, and the strongest cascades occurred in association with invertebrate herbivores and endothermic vertebrate predators. Expand
SIZE AND SURVIVAL OF INTERTIDAL PLANTS IN RESPONSE TO WAVE ACTION: A CASE STUDY WITH FUCUS GARDNERI
TLDR
“Optimal” plant sizes predicted by the model closely match the mean observed sizes of plants collected from exposed and protected locations, however, the match between observed and predicted plant sizes occurred not via differential survivorship, but by direct size modification resulting from plant tattering. Expand
The Keystone Species Concept: Variation in Interaction Strength in a Rocky Intertidal Habitat
TLDR
Variation in interaction strength between the original keystone predator, the seastar Pisaster ochraceus, and its primary prey, mussels is investigated, indicating that, as in Washington state, seastars prevent large adult M. californianus from invading lower intertidal regions, but only at wave—exposed, not wave—protected sites. Expand
Mechanical Consequences of Size in Wave‐Swept Algae
TLDR
Preliminary calculations show that these accelerational forces combine with drag to act as a size-dependent agent of mortality, constraining the size of these algae, suggesting that mechanical factors may be important in limiting thesize of intertidal macroalgae and that attention solely to biological constraints may be inappropriate.

Biogeographical patterns of rocky intertidal communities along the Pacific coast of North America
Aim Our aim in this paper is to present the first broad-scale quantification of species abundance for rocky intertidal communities along the Pacific coast of North America. Here we examine theExpand
Geographic variability in form, size and survival of Egregia menziesii around Point Conception, California
TLDR
Results indicate that region- ally specific morphological forms of E. menziesii seem to be uniquely adapted to maximize growth and survival under conditions typical of their native region, and may be advantageous within each of these regions. Expand
SPECIES INTERACTION STRENGTH: TESTING MODEL PREDICTIONS ALONG AN UPWELLING GRADIENT
TLDR
This model predicts that species interactions in benthic marine communities vary predictably with upwelling regimes, and quantified phytoplankton concentration and rates of mussel recruitment, mussels growth, mussel abundance, and sea star abundance to evaluate the relation between predation rates and key ecological processes and conditions.
