Large-scale spatial synchrony is ubiquitous in ecology. We examined 56
years of data representing chlorophyll density in 26 areas in British seas
monitored by the Continuous Plankton Recorder survey. We used wavelet
methods to disaggregate synchronous fluctuations by timescale and
determine that drivers of synchrony include both biotic and abiotic
variables. We tested these drivers for statistical significance by
comparison with spatially synchronous surrogate data. We generated
timescale-specific models, accounting for 61% of long-timescale (>
4yrs) synchrony in a chlorophyll density index, but only 3% of observed
short-timescale (< 4yrs) synchrony. The dominant source of
long-timescale chlorophyll synchrony was closely related to sea surface
temperature, through a Moran effect, though likely via complex
oceanographic mechanisms. The top-down action of Calanus finmarchicus
predation enhances this environmental synchronising mechanism and
interacts with it non-additively to produce more long-timescale synchrony
than top-down and climatic drivers would produce independently. Thus we
demonstrate interaction effects between Moran drivers of synchrony, a new
mechanism for synchrony that may affect many ecosystems at large spatial
scales.
