Salmon migratory adaptation in the Anthropocene
Human-induced changes to the Earth led scientists to declare a new epoch within the Cenozoic era – the Anthropocene (Lewis and Maslin 2015). Climate change, which includes rising temperatures, is a well-documented result of environmental modification by humans and is expected to continue if action...
