Integrating spatial and phylogenetic information in the fourth-corner analysis to test trait-environment relationships

The fourth-corner analysis aims to quantify and test for relationships between species traits and site-specific environmental variables, mediated by site-specific species abundances. Since there is no common unit of observation, the significance of …

Combining the fourth-corner and the RLQ methods for assessing trait responses to environmental variation

Assessing trait responses to environmental gradients requires the simultaneous analysis of the information contained in three tables: L (species distribution across samples), R (environmental characteristics of samples), and Q (species traits). Among …
