Accidental epiphytes: Ecological insights and evolutionary implications
Ecological Monographs, Volume 92, Issue 4, November 2022., 2022 Abstract Vascular epiphytes are an important component of many ecosystems and constitute a substantial part of global plant diversity. In this context, accidental epiphytism, that is, the opportunistic epiphytic growth of typically terrestrial species, deserves special attention because it provides crucial insights into the global distribution of ...

Population Ecology, Volume 64, Issue 2, Page 80-92, April 2022., 2022 This review analyzed the main dispersion indices and coefficients published between 1915 and 1975 and applied to the analysis of the spatial distribution of plant species. Despite a long history in ecological studies, these measurements do not meet the growing interest of ecologists in identifying factors related to distribution patterns.
