Data and code from: How do synchrony in survival and productivity influence abundance synchrony in European landbirds?

Synchronous fluctuations in species’ abundance are influenced by synchrony
in underlying rates of productivity and survival. However, it remains
unclear how rate synchrony varies in space and time, contributes to
abundance synchrony, and differs among species. Using long-term annual
count (number of adults captured), adult survival and productivity (number
of juveniles captured per adult) data for breeding land-birds at ringing
sites across Europe, we show that synchrony is strongest and largest-scale
in productivity, and weakest and smallest-scale in counts. However, counts
fluctuate more synchronously with survival than they do with productivity.
These patterns hold for species which do not migrate or only migrate
within Europe (European-residents) and those migrating to sub-Saharan
Africa (subSaharan-migrants), but the periodicity of productivity and
survival synchrony is longer in European-residents than
subSaharan-migrants. This suggests that survival and productivity
synchrony may interact to weaken abundance fluctuations, but are
influenced by environmental drivers operating over differing timescales in
European-resident and subSaharan-migrantspecies.
