El Yunque National Forest,
Mameyes Watershed
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 nonnative species
