Although theory suggests geographic variation in species' performance is determined by multiple niche parameters, little consideration has been given to the spatial structure of interacting stressors that may shape local and regional vulnerability to global change. Here, we use spatially explicit mosaics of carbonate chemistry, food availability and temperature spanning 1280 km of coastline to test whether persistent, overlapp...

To distinguish the intertidal states of emergence, splash, surge, and submergence and record their relative durations, we deployed a water‐level logger paired with a temperature logger in the mid‐intertidal zone at each of 10 wave‐exposed sites during the summer in the northeast Pacific. Relative durations of intertidal states were different among the different sites, even at sites close together. Splash was temporally variabl...

Oceanic sources of nutrients to the kelp forests of the Santa Barbara Channel were diagnosed using time series from three moorings in 12‐ to 17‐m water depth. An in situ nitrate autoanalyzer on the moorings provided the first high‐resolution time series of nitrate + nitrite (dissolved inorganic nitrogen, DIN) concentrations for this environment. Measurements between February 2001 and May 2003 show that the major mechanisms tha...
