Abstract	Functional connectivity reflects the ease with which an organism can access different locations within its environment. Because functional connectivity can significantly influence dispersal, habitat selection, and ultimately the viability of populations, it is central to understanding and predicting biological responses to anthropogenic disturbance. Currently, no consensus exists on how to measure functional connectivity.Species-centered approaches such as translocation experiments have recently been advocated because they enable strong inferences about functional connectivity. The use of these types of experiments is increasing rapidly, but to date there has been no synthesis of the wide range of methods available to minimize possible study design problems. Here, we review the recent literature on translocation experiments and highlight potential confounds that may lead to inappropriate conclusions from translocation studies.We report several approaches that can limit the degree to which these confounds affect inferences. We briefly describe paired and repeated-measures designs that use mixed models to address lack of spatial and temporal independence as means for coping with confounds.Such approaches to the design and analyses of translocation experiments should facilitate high-quality measurements of landscape functional connectivity. We encourage investigators to continue functional connectivity research that capitalizes on the advantages of translocations while applying rigorous study designs.
