Evidence of Spatial Synchrony in the Spread of an Invasive Forest Pest.

ABSTRACT: Because population growth is a key component of range expansion, spatial synchrony in population growth along a species' range edge may lead to spatial synchrony in range expansion. However, demographic stochasticity in low-density range-edge populations and stochastic long-distance dispersal may disrupt the synchronisation of range expansion. Here, we investigate whether rates of spread by an invasive species, the spongy moth and exhibit spatial synchrony. We also evaluate if climatic oscillations at multi-annual timescales arising from teleconnections synchronise spread at similar timescales. We applied extensions of wavelet analysis to spatiotemporal data on climate variables and range-edge abundances during 1990-2020. Synchrony in spread occurred throughout the entire study area, but o
