Multiple genetic lineages of anadromous migratory Mekong catfish revealed by mtDNA control region and cytochrome .

Population genetic structure of migratory fishes can reflect ecological and evolutionary processes. is a critically important anadromous catfish in the Mekong River, and its migration pathways and genetic structure have attracted much interest. To investigate, we quantified the genetic diversity of this species using the control region (D-loop) and Cytochrome (Cyt) of the mitochondrial genome.

Impacts of Dams and Global Warming on Fish Biodiversity in the Indo-Burma Hotspot.

Both hydropower dams and global warming pose threats to freshwater fish diversity. While the extent of global warming may be reduced by a shift towards energy generation by large dams in order to reduce fossil-fuel use, such dams profoundly modify riverine habitats. Furthermore, the threats posed by dams and global warming will interact: for example, dams constrain range adjustments by fishes that might compensate for warming temperatures.
