Model‐based mapping of assemblages for ecology and conservation management: A case study of demersal fish on the Kerguelen Plateau
Abstract Aim Quantifying biological assemblages and their environment is a fundamental, yet statistically challenging task in conservation ecology. Here, we use a recently developed approach called Regions of Common Profile ( RCP ) to quantify and map the distribution of demersal fish assemblages in...
