Abstract Habitat fragmentation increases forest edges, which in turn influence the microclimate to ferns are exposed. Ferns do not depend on pollinators or dispersers, make abiotic variables responsible for triggering manifestation of their phenophases. Phenology has been an important tool understanding effects habitat plant behaviour. Our aims were compare phenology populations fern Ctenitis submarginalis at a natural edge, artificial edge and interior determine whether effect influence. Populations C. monitored these three subareas Araucaria 2 years. Relative air humidity, temperature, precipitation, photosynthetically active radiation, photoperiod soil moisture concomitantly with collection phenological data each subarea. Among populations, that had greatest number individuals highest intensity sporangium formation leaf senescence. Only reproductive event (sporangium formation) all was seasonal. The seasonality formation. edges (natural artificial) more affected by than those interior. Abiotic sensitive alterations effect, such as relative influenced vegetative events edges. On other hand, photoperiod, is constant from year year, overlapped environmental factors Thus, we evidenced heterogeneity responses
