- Abstract
The intra‐ and interspecific facets of biodiversity have traditionally been analysed separately, limiting our understanding of how evolution has shaped biodiversity, how biodiversity (as a whole) alters ecological dynamics and hence eco‐evolutionary feedbacks at the community scale. Here, we propose using candidate genes phylogenetically‐conserved across species and sustaining functional traits as an inclusive biodiversity unit transcending the intra‐ and interspecific boundaries. This framework merges knowledge from functional genomics and functional ecology, and we first provide guidelines and a concrete example for identifying phylogenetically‐conserved candidate genes (PCCGs) within communities and for measuring biodiversity from PCCGs. We then explain how biodiversity measured at PCCGs can be linked to ecosystem functions, which unifies recent observations that both intra‐ and interspecific biodiversity are important for ecosystem functions. We then highlight the eco‐evolutionary processes shaping PCCG diversity patterns and argue that their respective role can be inferred from concepts derived from population genetics. Finally, we explain how PCCGs may shift the field of eco‐evolutionary dynamics from a focal‐species approach to a more realistic focal‐community approach. This framework provides a novel perspective to investigate the global ecosystem consequences of diversity loss across biological scales, and how these ecological changes further alter biodiversity evolution.
