The Keystone Species Concept: Variation in Interaction Strength in a Rocky Intertidal Habitat
The usefulness and generality of the keystone species concept has recently been questioned. We investigated variation in interaction strength between the original keystone predator, the seastar… Expand
The humboldt current system of northern and central chile : Oceanographic processes, ecological interactions and socioeconomic feedback
The Humboldt Current System (HCS) is one of the most productive marine ecosystems on earth. It extends along the west coast of South America from southern Chile (∼42°S) up to Ecuador and the… Expand
More than a meal… integrating non-feeding interactions into food webs.
Organisms eating each other are only one of many types of well documented and important interactions among species. Other such types include habitat modification, predator interference and… Expand
Geographic variation of southeastern Pacific intertidal communities
We conducted field surveys of rocky intertidal communities at 18 sites distributed between 29°S and 36°S on the coast of central Chile in order to document broad patterns of functional and trophic… Expand
QUANTIFYING VARIATION IN THE STRENGTHS OF SPECIES INTERACTIONS
Understanding how the strengths of species interactions are distributed among species is critical for developing predictive models of natural food webs as well as for developing management and… Expand
Scales of benthic-pelagic coupling and the intensity of species interactions: from recruitment limitation to top-down control.

Large and usually unpredictable variation in species interaction strength has been a major roadblock to applying local experimental results to large-scale management and conservation issues. Recent… Expand
Mollusk species diversity in the Southeastern Pacific: why are there more species towards the pole?
The most ubiquitous and well recognized diversity pattern at large spatial scales is the latitudinal increase in species richness near the equator and decline towards the poles. Although several… Expand
Interhemispheric comparison of recruitment to intertidal communities: pattern persistence and scales of variation.
Recruitment variation can be a major source of fluctuation in populations and communities, making it difficult to generalize results. Determining the scales of variation and whether spatial patterns… Expand
Avoiding offshore transport of competent larvae during upwelling events: The case of the gastropod Concholepas concholepas in Central Chile
The coast of central Chile is characterized by the occurrence of coastal upwelling during the austral spring and summer seasons, which probably has important consequences for the cross-shelf… Expand
Integrating abundance and functional traits reveals new global hotspots of fish diversity
Species richness has dominated our view of global biodiversity patterns for centuries. The dominance of this paradigm is reflected in the focus by ecologists and conservation managers on richness and… Expand
