Only those species with a value greater than 50 are listed. Grouping factor refers to number in parentheses in regression tree splits, identifying where each discriminant species was found Trophic categories: BH, browsing herbivore; SH, scraping herbivore; EX, excavator; I, invertivore; MP, mesopredator; O, omnivore; P, piscivore.
