Zamborain-Mason et al. (Ecol. Lett., 20, 2017, 815-831) state that they have newly proposed network metrics that account for node self-connections. Network metrics incorporating node self-connections, also referred to as intranode (intrapatch) connectivity, were however already proposed before and have been widely used in a variety of conservation planning applications.
Keywords: Connectivity; conservation planning; ecological networks; graph-based metrics; habitat availability; network metrics; population persistence; probability of connectivity; reachable habitat; reserve networks.
