POTENTIAL DISTRIBUTION OF FOUR SPECIES OF CHEILANTHOIDS FERNS FROM SOUTH AMERICA
DANIEL CACHARANI
Abstract
We present the current and potential distribution of four fern species, Doryopteris concolor, D. triphylla, Hemionitis tomentosa and Pellaea ovata (Cheilathoideae, Pteridaceae), in order to determine the biogeographic region that they occupy. The study involved the use of herbaria records and online databases, and the Maxent modeling program with 19 known bioclimatic variables. The predictive capacity of all models was evaluate and the most important bioclimatic variables in the predictive model for each species were determined. The results showed that the distribution of the species Doryopteris concolor and Hemionitis tomentosa has greater coincidence with the distribution of the seasonal neotropical South American dry forests than Doryopteris triphylla and Pellaea ovata.
