Thermodynamics, maximum power, and the dynamics of preferential river flow structures at the continental scale

The organization of drainage basins shows some reproducible phenomena, as exemplified by self-similar fractal river network structures and typical scaling laws, and these have been related to energetic optimization principles, such as minimization of Hose Reducing Joiner stream power, minimum energy expenditure or maximum "access".Here we describe

Protecting Japanese giant salamanders (Andrias japonicus) in the Nawa River Basin, Japan: policy recommendations addressing water pollution and waterway disruption

The Japanese giant salamander, Andrias japonicus, is an iconic but declining species of aquatic amphibian.A population within the Nawa River Basin of Tottori Prefecture persists but faces two significant threats.The first major threat is waterway obstructions, in the form of dams, weirs, and concrete embankments, which severely fragment and degrade
