Limited emigration from an outbreak of a forest pest insect.

Molecular ecology - 1 Nov 2011

Ronnås Cecilia, Cassel-Lundhagen Anna, Battisti Andrea, Wallén Johan, Larsson Stig

Abstract excerpt

Population density and individual dispersal behaviour affect species' distribution dynamics. Population densities vary over time, and some species occasionally increase to very high numbers, for example during outbreaks. In such situations, populations are expected to expand into new areas as a result of density-dependent dispersal which sometimes even results in range expansion. A local population of the...
