New antecedents on the distribution and ecology of Botrychium dusenii (H. Christ.) Alston (Ophioglossaceae) associated with anthropogenic environments in the Coyhaique province, Aysén Region, Chile

Abstract

Conducting botanical and ecological explorations with the objective of studying the floristic composition of post-fire
communities in the Aysén Region, we found new regional records of the fern Botrychium dusenii (H. Christ.) Alston
(Ophioglossaceae). These findings, that extend the north limit of the species distribution, occurred in open areas affected
by historical human-provoked fires (happening between 1950 and 1960) during the regional process of colonization.
