A comparison of metrics for estimating phylogenetic signal under alternative evolutionary models

Abstract: Several metrics have been developed for estimating phylogenetic signal in comparative data. These may be important both in guiding future studies on correlated evolution and for inferring broad-scale evolutionary and ecological processes (e.g., phylogenetic niche conservatism). Notwithstanding, the validity of some of these metrics is under debate, especially after the development of more sophisticated model-based approaches that estimate departure from particular evolutionary models (i.e., Brownian motion).

“…Most were not significantly greater than zero: of 72 tests done, only 11 were significantly greater than zero at the 5% level, and only one at the 1% level (Table ). Values for Argyranthemum and Descurainia are consistent with Brownian motion‐level niche conservatism for temperature, while values for the other clades across all climatic variables are more consistent with lower levels of climatic niche similarity than expected under Brownian motion evolution (Diniz‐Filho et al ., ).…”

“…Although Moran’s I, Blomberg’s K , and the Mantel tests are closely related mathematically [41,42], their performance depends heavily on the choice of genetic distance model [42]. For this reason, we used three different models of genetic distance.…”
