“…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).…”

“…On the other hand, RS deposition presented its maximum in August for the edge, and between September and December for the other strips ( Figure 2D). The highest seed yields in semi-deciduous seasonal forests are generally observed at the end of the dry season (between August and September) and are usually related to fruit production in that period (Diniz & Pagano, 1997;Toscan et al, 2017).…”

The edge effect makes forest communities more susceptible to changes and may cause changes in different ecosystem characteristics such as litter production. The objective of this work was to evaluate the edge effect on the contribution of litter and its temporal variation in a Semi-Deciduous Seasonal Forest fragment located in Vitória da Conquista, BA, Brazil. Four sampling ranges were delimited in the forest fragment: edge (0-10 m from the edge), transition 1 (40-50 m from the edge), transition 2 (80-90 m from the edge) and interior (400-410 m from the edge). The produced litter was collected monthly. The main litter components were leaves and branches in all sampling ranges. The contribution of the other fractions obeyed different orders at the edges (bark > reproductive structures) and interior (reproductive structures > bark). The edge effect did not influence the contribution of total litter and its temporal variation, only manifesting in the production of reproductive structures.

“…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.…”

The litter is an important way of returning the organic matter to the soil, through the cycling of the nutrients, aiding in the development of the vegetation present in the ecosystems. The study aimed to estimate the spatio-temporal variation of deposition, accumulation and decomposition of the litter present in the preserved caatinga vegetation, located in the RPPN Fazenda Tamanduá in Santa Terezinha-PB, Brazil and the interference of climatic variables in the dynamics of these events. The research was conducted at RPPN Fazenda Tamanduá, in Santa Terezinha-PB, Brazil. The deposition of litter on 20 collectors of 1.0 m × 1.0 m was collected monthly in two periods: period I (August/2015 to July/2016) and period II (August/2016 to July/2017), the collected material was separated into leaves, branches + barks, reproductive and miscellaneous fractions. To estimate the rate of decomposition the litter accumulated on the forest floor was quantified using a 0.5 m × 0.5 m metal frame. The deposition of the total litter in periods I and II was 2,356.83 kg ha-1 and 1,163.67 kg ha-1, respectively. The leaf fraction was the one that contributed the most during the two collection periods. The analysis of the data allowed to conclude that the total litter deposition in the two periods is in line with the average production for the Caatinga. The increase in precipitation provided higher deposition of litter after the rainy season. Due to several factors, the decomposition of litter in the caatinga is slower than in other biomes.

“…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).…”

Tree species that produce resources for fauna are recommended for forest restoration plantings to attract pollinators and seed dispersers; however, information regarding the flowering and fruiting of these species during early growth stages is scarce. We evaluated the reproductive phenology of animal‐dispersed tree species widely used in Atlantic Forest restoration. We marked 16 animal‐dispersed tree species in 3‐ to 8‐year‐old forest restoration plantings in Itu‐São Paulo, southeast Brazil. We noted the age of the first reproductive event, flowering and fruiting seasonality, percentage of trees that reached reproductive stages, and intensity of bud, flower, and fruit production for each species. Flowering and fruiting are seasonal for most species; only two, Cecropia pachystachya and Ficus guaranitica, exhibited continuous flowering and fruiting throughout the year; we also identified Schinus terebinthifolia and Dendropanax cuneatus fruiting in the dry season during resource scarcity. Therefore, we recommend all as framework species, that is, species that are animal‐dispersed with early flowering and fruiting potential, for forest restoration. Further, we recommend identifying and planting similar animal‐dispersed tree species that produce fruits constantly or in the dry season to maximize fauna resource availability throughout the year in tropical forest restoration plantings.
