The thermal biology of Carcinus maenas as a tool for conservation, mitigation, and invasion predictions
Carcinus maenas is a thermally tolerant invasive species that have successfully colonized every continent except Antarctica. Invasive species negatively impact native species, and C. maenas, in particular, has been implicated in the local losses of several ecologically important species. Anthropogen...
