Revisiting Adaptive Traits and Epiphylly in Tropical Leafy Liverworts (Family Lejeuneaceae).
Several morphological and life-history traits in the leafy liverwort family Lejeuneaceae are hypothesized to be adaptations for living on broad leaves of vascular plants (epiphylly). However, there has been no direct evidence or experiment to test such a hypothesis. In this study, I used the recently published phylogeny of Lejeuneaceae and trait data from published monographs to determine whether the proposed “adaptive” traits were correlated to each other and with epiphylly. The results did not show any significant correlation among the traits of interest, or correlation of the traits with epiphylly. The findings suggested that these “adaptive” traits were not specific adaptations for epiphylly in Family Lejeuneaceae, or possibly not even the traits that were under selection for epiphylly. Broader selection of traits will be needed for better explaining the adaptation of the liverworts to leaf space.
