Abstract
Landscape connectivity can be viewed from two perspectives that could be considered as extremes of a gradient functional connectivity refers to how the behavior of a dispersing organism is affected by landscape structure and elements and structural connectivity depends on the spatial configuration of habitat patches in the landscape like vicinity or presence of barriers Here we argue that dispersal behavior changes with landscape configuration stressing the evolutionary dimension that has often been ignored in landscape ecology Our working hypothesis is that the functional grain of resource patches in the landscape is a crucial factor shaping individual movements and therefore influencing landscape connectivity Such changes are likely to occur on the shortterm some generations We review empirical studies comparing dispersal behavior in landscapes differing in their fragmentation level ie with variable resource grain We show that behavioral variation affecting each of the three stages of the dispersal process emigration displacement or transfer in the matrix and immigration is indeed likely to occur according to selective pressures resulting from changes in the grain of the landscape mortality or deferred costs Accordingly landscape connectivity results from the interaction between the dispersal behavior of individuals and the grain of each particular landscape The existence of this interaction requires that connectivity estimates being based on individualbased models least cost distance algorithms and structural connectivity metrics or even Euclidian distance should be carefully evaluated for their applicability with respect to the required level of precision in speciesspecific and landscape informationWe thank Thomas Merckx and Nicolas Schtickzelle for their input to this study Virginie M Stevens provided constructive comments on a first draft This work was funded by a grant from UCL to MB and HVD FSR06 “Behavioral Ecology of Dispersal” by grants from the Office of Scientific and Cultural Affairs Belgian Federal Government to MB contracts OSTCPADD II EV10/16A 2000–2004 PADD II EV10/26A 2003–2006 and PADD II support action 2004–2006 MB also acknowledges financial support from the Belgian National Fund for Scientific Research FRFC 2455605
