How to measure and test phylogenetic signal - Münkemüller

Phylogenetic signal is usually described as the tendency of related biological species to resemble each other more than any other species that is randomly picked from the same phylogenetic tree. In other words, phylogenetic signal can be defined as the statistical dependence among species' trait values that is a consequence of their phylogenetic relationships. The traits (eg. morphological, ecological, life-history or behavioural traits) are inherited characteristics – meaning the trait value… WebFeb 27, 2024 · The retention of niche-related ecological traits over time, causing that closely related species are more ecologically similar than would be expected based on their phylogenetic relationships (Losos, 2008), is termed phylogenetic niche conservatism (PNC) and strong PS has often been interpreted as evidence of it (Wiens et al., 2010).
