Abstract EN
The distance from a source patch that dispersing insects reach depends on the number of dispersers, or random draws from a probability density function called a dispersal kernel, and the shape of that kernel.
This can cause asymmetrical dispersal between habitat patches that produce different numbers of dispersers.
Spatial distributions based on these dynamics can explain several ecological patterns including megapopulations and geographic range boundaries.
I hypothesized that a locally extirpated longhorned beetle, the sugar maple borer, has a new geographical range shaped primarily by probabilistic dispersal distances.
I used data on occurrence from Ontario, Canada to construct a model of geographical range in Indiana, USA based on maximum dispersal distance scaled by habitat area.
This model predicted the new range boundary within 500 m very accurately.
This beetle may be an ideal organism for exploring spatial dynamics driven by dispersal.
