1. Modeling Complex Interactions of Overlapping River and Road Networks in a Changing Landscape http://biocomplexity.warnercnr.colostate.edu/ El Yunque National Forest, Mameyes Watershed

2. River Road Networks Flows of energy through river and road networks, as well as food webs, have some fundamental similarities A hierarchy of physical processes is altered by distinct thresholds of human access and use of rivers Different locations within the spatial hierarchy of a drainage network alter access and intensities of land use as well as species diversity Aquatic food webs respond to selective harvest of species and cumulative additions of non- native species
