This paper is a part two of a study investigating the relative importance of the built environment, sociodemographic,
and attitudinal factors on mode choice. A semi-experimental approach that aims to
measure causal effects of the built environment is utilized. This paper reports spatial analysis, survey and
modeling results for San Francisco, CA, USA and compares the results with a previous similar study in
Rome, Italy. Results reveal that the local street network’s integration is important in both cities and that in

Aim: Although the effects of life history traits on population density have been investigated widely, how spatial environmental variation influences population density for a large range of organisms and at a broad spatial scale is poorly known. Filling this knowledge gap is crucial for global species management and conservation planning and to understand the potential impact of environmental changes on multiple species.

Location: Global.
