Urban sprawl as a risk factor in motor vehicle crashes Urban sprawl as a risk factor in motor vehicle crashes
A decade ago, compactness/sprawl indices were developed for metropolitan areas and counties which have been widely used in health and other research. In this study, we first update the original county index to 2010, then develop a refined index that accounts for more relevant factors, and finally seek to test the relationship between sprawl and traffic crash rates using structural...

Taking a systems approach to ecological systems Taking a systems approach to ecological systems
Increasingly, there is interest in a systems-level understanding of ecological problems, which requires the evaluation of more complex, causal hypotheses. In this issue of the Journal of Vegetation Science, Soliveres et al. use structural equation modeling to test a causal network hypothesis about how tree canopies affect understorey communities. Historical analysis suggests structural...

Landscape structure affects specialists but not generalists in naturally fragmented grasslands Landscape structure affects specialists but not generalists in naturally fragmented grasslands
Understanding how biotic communities respond to landscape spatial structure is critically important for conservation management as natural landscapes become increasingly fragmented. However, empirical studies of the effects of spatial structure on plant species richness have found inconsistent results, suggesting that more comprehensive approaches are needed. In this study, we asked how...

Beyond just sea-level rise: Considering macroclimatic drivers within coastal wetland vulnerability assessments to climate change Beyond just sea-level rise: Considering macroclimatic drivers within coastal wetland vulnerability assessments to climate change
Due to their position at the land-sea interface, coastal wetlands are vulnerable to many aspects of climate change. However, climate change vulnerability assessments for coastal wetlands generally focus solely on sea-level rise without considering the effects of other facets of climate change. Across the globe and in all ecosystems, macroclimatic drivers (e.g., temperature and rainfall...

Compact development and VMT: environmental determinism, self-selection, or some of both? Compact development and VMT: environmental determinism, self-selection, or some of both?
There is a long-running debate in the planning literature about the effects of the built environment on travel behavior and the degree to which apparent effects are due to the tendency of households to self-select into neighborhoods that reinforce their travel preferences. Those who want to walk will choose walkable neighborhoods, and those who want to use transit will choose transit...
