Mapping differences in mammalian distributions and diversity using environmental DNA from rivers.

Finding more efficient ways to monitor and estimate the diversity of mammalian communities is a major step towards their management and conservation. Environmental DNA (eDNA) from river water has recently been shown to be a viable method for biomonitoring mammalian communities. Most of the studies to date have focused on the potential for eDNA to detect individual species, with little focus on describing patterns of community diversity and structure.
