Abstract

BRAVO-MONASTERIO, Pablo; PENAILILLO, Patricio  and  FAJARDO, Alex. 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. Gayana Bot. [online]. 2012, vol.69, n.1, pp.208-211. ISSN 0717-6643.  http://dx.doi.org/10.4067/S0717-66432012000100025.

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.
