Butterfly Monitoring Methods: The ideal and the Real World

WebThe OU-based method enables us to model the evolution of a trait across a phylogenetic tree in response to different selective regimes (Hansen, 1997; Butler & King, 2004; Hansen et al., 2008). These selective regimes themselves can be values or states of other traits, or those of the environment (predictor variables).
