Accounting for multiple dimensions of biodiversity to assess surrogate performance in a freshwater conservation prioritization

Although freshwater ecosystems support a disproportionately large number of species, decision-support tools for prioritizing protected area efforts have mostly been implemented in marine and terrestrial environments. Systematic conservation planners rely on surrogate metrics to represent unsampled e...
