Fifteen collectors of 0.25 m 2 each were used, distributed in three transects per study area (A1, A2 and AR). The highest litterfall p roduction occurred in AR (8 .13 Mg ha -1 yr -1 ), followed by A2 (4 .26 M g ha -1 yr -1 ) and A1 (2 .74 Mg ha -1 yr -1 ). The AR area produced significantly more leaves, reproductive material and wastes. This can be explained by its more develo ped forest structure, wit h large trees, more closed canopy and greater number of epiphytes. On the other hand, areas A1 and A2 produced significant amounts of thin stems. These areas have a higher proportion of species in early successional stages, a higher den sity of thin trees a nd a more open canopy, being subject to winds, which could result in greater production and fall of branches. The results of this study highlight the importance of litterfall production in different successional stages, becoming necessary studies with this emphasis to understand the nutritional dynamics of ecosystems, especially those that have suffered strong impacts in the past, such as op en -pit coal mining. 2017 artículo científico 0100-8307 https://www.redalyc.org/articulo.oa?id=467553545003 https://www.redalyc.org/journal/4675/467553545003/ https://www.redalyc.org/journal/4675/467553545003/html/ https://www.redalyc.org/journal/4675/467553545003/467553545003.epub https://www.redalyc.org/journal/4675/467553545003/movil en http://www.redalyc.org/revista.oa?id=4675 Ciência e Natura application/pdf Universidade Federal de Santa Maria Ciência e Natura (Brasil) Num.3 Vol.39 |
