- 摘要:
- Populations of North American river otters (Lontra canadensis) declined throughout large portions of the continent during the early 1900s due to

Data from: The architecture of river networks can drive the evolutionary dynamics of aquatic populations
- 负责人:
- DOI:

- 摘要:
- branched rivers show a 20-fold increase in the overall genetic diversity and a 7-fold increase in the genetic differentiation between local populations. Give
