Impacts of Dams and Global Warming on Fish Biodiversity in the Indo-Burma Hotspot
(a) Existing (solid circles) and planned dams (blank circles) in the Indo-Burma Region  with Mekong River shown in blue line. (b) Spatial arrangement of drainage basins, prior to construction of dams (i.e. ‘Pre-dam’ condition). (c) Fragmentation of the drainage basins due to man-made barriers, assuming that all planned dams are constructed. Note that the graphical images are illustrative only; see  for a precise map of Indo-Burma.
