Metapopulation‐scale resilience to disease‐induced mass mortality in a keystone predator: From stasis to instability Open
Mass mortality from disease epidemics challenges the resistance and resilience of populations and communities. Assessing the impacts and consequences of such events is crucially dependent on long‐term datasets. In 2013–2016, sea star wasti…

Impacts of Birds vs. Invertebrate Predators on Rocky Intertidal Community Structure Open
Most studies of species interactions in rocky intertidal communities focus on invertebrate predators and herbivores interacting with sessile invertebrates and macrophytes. However, shorebirds are usually a conspicuous presence on rocky sho…

Nitrogen use efficiency underlies cross-ecosystem variation in marine primary production Open
The supply of nitrogen (N) and the efficiency with which it is used by phytoplankton serve as two fundamental controls on the productivity of many marine ecosystems. Shifts in nitrogen use efficiency (NUE) can decouple primary production f…

Biogeographic Patterns in Density, Recruitment, Body Size and Zonation of Rocky Intertidal Predators Suggest Increased Population Vulnerability Near Southern Range Limits Open
Aim Surveying the demography of populations near species range edges may indicate their vulnerability to range contractions or local extinction as the climate changes. In the rocky intertidal, not only are latitudinal ranges constricted by…

Resistance of rocky intertidal communities to oceanic climate fluctuations Open
A powerful way to predict how ecological communities will respond to future climate change is to test how they have responded to the climate of the past. We used climate oscillations including the Pacific Decadal Oscillation (PDO), North P…

A unified meta‐ecosystem dynamics model: Integrating herbivore‐plant subwebs with the intermittent upwelling hypothesis Open
Determining the relative influence of biotic and abiotic processes in structuring communities at local to large spatial scales is best understood using a biogeographic comparative‐experimental approach. Using this approach, previous work s…

Community Theory: Testing Environmental Stress Models Open
Protocol for Testing Environmental Stress Models M&S1987; and M&O1990; were expressly proposed as landscape or meta-community models and briefly laid out protocols enabling tests of ESMs. Here I make those criteria more explicit. Thus, cri…

Coastal upwelling may strengthen the controls of herbivory and light over the population dynamics of <i>Hedophyllum sessile</i> in the Oregon rocky intertidal Open
Survival of early life history stages is critical to the successful establishment of benthic populations. Although light availability and herbivory are likely to influence the passage of marine macroalgae through a “recruitment bottleneck”…

Keystone predation: trait‐based or driven by extrinsic processes? Assessment using a comparative‐experimental approach Open
Keystone predation can be a determinant of community structure, including species diversity, but factors underlying “keystoneness” have been minimally explored. Using the system in which the original keystone, the sea star Pisaster ochrace…

Biogeography of ocean acidification: Differential field performance of transplanted mussels to upwelling-driven variation in carbonate chemistry Open
Ocean acidification (OA) represents a serious challenge to marine ecosystems. Laboratory studies addressing OA indicate broadly negative effects for marine organisms, particularly those relying on calcification processes. Growing evidence …

Remote sensing: generation of long‐term kelp bed data sets for evaluation of impacts of climatic variation Open
A critical tool in assessing ecosystem change is the analysis of long‐term data sets, yet such information is generally sparse and often unavailable for many habitats. Kelp forests are an example of rapidly changing ecosystems that are in …
