Caracterização Da Produção De Serapilheira E Da Chuva De Sementes Em Uma Reserva De Floresta Estacional Semidecidual, Paraná

Abstract: O objetivo do estudo foi analisar a produção de serapilheira e a chuva de sementes em um fragmento de Floresta Estacional Semidecidual do oeste do Paraná com 242 ha, que é conhecido como Reserva Particular de Patrimônio Natural Fazenda Santa Maria. O material foi coletado mensalmente de junho/2011 a maio/2012, em nove parcelas de 20 x 20 m, com o uso quatro coletores de 0,5 x 0,5 m em cada parcela. A serapilheira foi triada e pesada, e a chuva de sementes foi avaliada quanto à riqueza, forma de vida, categoria… Show more

“…The average annual litter production for the fragment as a whole was 4.3 Mg ha −1 (Table 4), a value close to that found in several studies in semi-deciduous seasonal forests in Brazil, such as by Bianchi et al (2016) (4.7 Mg ha −1 ), Werneck et al (2001) (5.0 Mg ha −1 ), Martins & Rodrigues (1999) (5.9 Mg ha -1 ) and Pinto et al (2008) (6.3 Mg ha −1 ). However, higher results were observed by other authors in studying this same forest typology, who obtained 11.7 Mg ha −1 (Pezzatto & Wisniewski, 2006) and 11.9 Mg ha −1 (Toscan et al, 2017).…”

“…This indicates that vegetation is responsive to water stress, using the fall of senescent plant material as a mechanism to reduce water loss through transpiration. This behavior is common in forests with a high proportion of deciduous species, which intensify the abscission of their leaves in the cold season (König et al, 2002), and has been observed in several studies on litter contribution in semi-deciduous and deciduous seasonal forests (Pinto et al, 2008;Santos Neto et al, 2015;Toscan et al, 2017).…”

“…A study by Toscan et al (2017), in the RPPN Fazenda Santa Maria, in Santa Terezinha de Itaipu-PR, observed that annual litter production was 11.886 kg ha -1 , however, it should be noted that this high result is generally reported for seasonal semideciduous forests, not occurring in dry tropical forests such as the Caatinga.…”

“…As they fruit in a resource‐scarce period, we recommend S. terebinthifolia and D. cuneatus as framework species. Cecropia pachystachya and D. cuneatus are found to be highly abundant in terms of seed rain (Toscan et al., 2017), C. pachystachya and S. terebinthifolia attract many frugivorous birds (Navarro et al., 2019; da Silva et al., 2015), and F. guaranitica is considered a keystone species in tropical forests (Pereira et al., 1995).…”
