However, the effect of multiple reproduction events overlapping generations on the front speed can be very important especially for species with a long life spam . Only in one-dimensional space has this approximation been relaxed previously, although almost all biological invasions take place in two dimensions. Here we present a model that takes into account the overlapping generations effect or, more generally, the stage structure of the population , and we analyze the main differences with the corresponding nonoverlappinggenerations results" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "American Physical Society" , "dc.relation.isformatof": "Reproducció digital del document publicat a: http://link.aps.org/doi/10.1103/PhysRevE.80.051918" , "dc.relation.ispartof": "© Physical Review E, 2009, vol. 80, núm. 5, p. 051918-1 - 051918-9" , "dc.relation.ispartofseries": "Articles publicats (D-F)" , "dc.rights": "Tots els drets reservats" , "dc.subject": "Kernel, Funcions de" , "dc.subject": "Kernel functions" , "dc.subject": "Funcions de variables complexes" , "dc.subject": "Invasions biològiques -- Models matemàtics" , "dc.subject": "Biological invasions -- Mathematical models" , "dc.title": "Fronts from two-dimensional dispersal kernels: Beyond the nonoverlapping-generations model" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/openAccess" , "dc.embargo.terms": "Cap" , "dc.type.version": "info:eu-repo/semantics/publishedVersion" , "dc.identifier.doi": "http://dx.doi.org/10.1103/PhysRevE.80.051918" , "dc.identifier.eissn": "1550-2376" }
