Does biodiversity respond to embedded spectra of environmental variability

Recent research conducted both in marine and terrestrial habitats has emphasized the role that different spectra of environmental variability (generally indicated as environmental ‘colour’) have in driving changes in distribution and abundance of populations. It has been suggested that many ecological processes are autocorrelated in space (‘red’ spectra of variability) and some studies have tested the hypothesis that this should result in similar patterns of autocorrelation in spatial distribution of populations. Whilst some of the evidence supports this hypothesis, other studies have shown that populations often fluctuate independently in space and/or time (‘white’ spectra of variability).

The Environmental Modulation Biodiveristy and Ecosystem Dynamics (EMBED) workshop lead by Dr Lisandro Benedetti-Cecchi, was one of the first workshops funded by EuroCoML. The workshop was held in Pisa, Italy from the 27 - 29 April 2006 and the workshop report is available to be viewed online.

Although EMBED has so far not been successful in obtaining funding, this has not prevented them from publishing papers or attending conferences. The most recent publication is by Michael Burrows from the Scottish Association for Marine Science.
