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

天然边缘和人工边缘对物候的影响：滨海下睾丸炎的个案研究
栖息地的碎片化增加了森林的边缘，进而影响了蕨类植物所处的微气候。蕨类植物不依赖授粉剂或分散剂，而传粉剂或分散剂是造成触发其表相表达的非生物变量的生物。物候学一直是了解生境破碎化对植物行为影响的重要工具。我们的目的是比较自然边缘，人工边缘和森林内部的近缘蕨蕨类植物种群的物候，并确定边缘效应是否有影响。滨海梭菌的种群在南洋杉森林的这三个分区中进行了2年的监测。相对湿度，空气温度，降水，光合有效辐射，光周期和土壤湿度的监测与每个分区的物候数据的收集有关。在这些种群中，人工边缘的种群数量最多，孢子囊形成和叶片衰老的强度最高。所有子区域中只有种群的生殖事件（孢子囊形成）是季节性的。森林内部种群的孢子形成季节最多。森林边缘（天然和人工）的蕨类受边缘效应的影响大于森林内部的蕨类。对边缘效应引起的变化更敏感的非生物变量，例如相对空气湿度，土壤湿度和温度，影响边缘的植物生长。另一方面，每年不变的光周期与森林内部其他环境因素的影响重叠。因此，我们在森林边缘的蕨类植物的物候响应中证明了异质性。
