Here we present the results of the analysis of synchrony in annual population count, productivity, and survival for 26 species across 995 sites monitored from 1998 to 2019 under the European Constant Effort Scheme (CES) (Morrison et al. in prep.).

More exciting synchrony-based results can be read in the paper and many happy hours can be spent exploring our maps of abundance and demographic synchrony here: synchrony.uea.ac.uk.

Using wavelet analysis, we show that synchrony in both demographic rates occurred more commonly over long timescales in European-resident species and short timescales in subSaharan-migrant species.

Using spatial correlograms we estimated the scale and strength of synchrony and show that synchrony is strongest and largest scale in productivity and weakest and smallest scale in count.
