“…In the Mabea fistulifera plantation, the higher total litterfall occurred in the dry season (mainly between July and September) in all fertilization treatments (Figure 4). This pattern corroborated the results observed in an Amazon-Cerrado Transition Forest in Mato Grosso (Silva et al, 2009) and in different physiognomies of Cerrado (Cianciaruso et al, 2006;Giácomo et al, 2012). Higher litterfall influenced by higher leaf fall during the dry season occurs for many tree species as a strategy to overcome water deficit (Silva et al, 2014).…”

“…The high contribution of leaves, which commonly reaches 60% or more of total litter, was also observed in different tropical forest ecosystems (Cianciaruso et al, 2006;Giácomo et al, 2012;Schumacher et al, 2004Schumacher et al, , 2013.

“…6/9 Giácomo RG, Alves MC, Camara R, Pereira MG, Arruda OG, Souto SN et al Floresta e Ambiente 2017;24: e20160028 The Pearson correlation did not present significant values between total annual litterfall and precipitation, nor between total annual litterfall and temperature in both of the plantations and in all treatments ( Table 2). The absence of significant correlation between litter production and meteorological factors, such as precipitation and temperature, was also observed in mesophytic forest and savanna (Cianciaruso et al, 2006;Giácomo et al, 2012). According to Scoriza & Piña-Rodrigues (2014), the correlation between litterfall (total and its fractions) in tropical forest ecosystems and meteorological factors (precipitation and temperature) may not be significant in considering evaluation of litterfall during the same month.…”

This study aimed to test the effects of fertilization with organic compost from industrial production of pulp on the litterfall and nutrient input of monospecific plantations in a loan area. The treatments consisted of three doses of the organic compost D 10 , D 15 and D 20 (10, 15 and 20 Mg ha -1 , respectively), mineral conventional fertilization (D AM ) and no fertilization (D 0 ) in land plots (N = 4/treatment/species; 15 x 12 m). Litterfall was monthly collected by two traps (0.72 m 2 /plot) and sorted out into leaves, twigs, seeds, flowers, fruits and others. We determined the input of nitrogen, phosphorous and potassium. There were no differences among the treatments and between species in terms of total annual litterfall. The higher nutrient input was obtained by D AM, followed by D 10 , in both plantations. The annual nutrient input was higher for the litterfall on the E. urograndis plantation.

“…Abscission in evergreen rain forests occurs with more intensity when day length, solar radiation, temperature, air relative humidity, rainfall and consequent leaf fl ush increases (Larcher 1986, van Schaik et al 1993. Some tropical and subtropical ecosystems with pronounced seasonality, such as deciduous and semideciduous forests, savannas and some Amazonian forests, generally present the highest leaf litterfall in dry season (Klinge & Rodrigues 1968, Scott et al 1992, Cesar 1993, König et al 2002, Cianciaruso et al 2006, Silva et al 2007, Pallardy 2008. However, some of these ecosystems also present peak of leaf fall at the beginning of rainy season or in late dry season (Dias et al 2002, Pezzatto & Wisniewski 2006.…”

-(Patterns of litter production in a secondary alluvial Atlantic Rain Forest in southern Brazil). Above-ground litter production is one of the most accessible ways to estimate ecosystem productivity, nutrient fl uxes and carbon transfers. Phenological patterns and climatic conditions are still not fully explained well for tropical and subtropical forests under less pronounced dry season and non-seasonal climates, as well as the interaction of these patterns with successional dynamics. Monthly litterfall was estimated for two years in a 9 to 10 year old secondary alluvial Atlantic Rain forest. Total litterfall was higher in the site with more developed vegetation (6.4 ± 1.2 ton ha -1 year -1 ; 95% confi dence interval) as compared to the site with less developed vegetation (3.0 ± 1.0 ton ha -1 year -1 ). The monthly production of 11 litter fractions (eight fractions comprising the leaf litter of the seven main species of the community and other species; reproductive parts, twigs ≤ 2 cm diameter, and miscellaneous material) were correlated with meteorological variables making possible to identify three patterns of deposition. The main pattern, dominated by leaf-exchanging species, consisted of a cycle with the highest litterfall at the beginning of the rainy season, preceding by basically three months the peaks of the annual cycles of rainfall and temperatures. Other two patterns, dominated by brevi-deciduous species, peaked at the end of the rainy season and at the end of the non-rainy season. Tropical and subtropical dry forests that present the highest leaf fall gradually earlier than rain forests (as the studied sites) are possibly related to the start of senescence process. It seems that such process is triggered earlier by a more severe hydric stress, besides other factors linked to a minor physiological activity of plants that result in abscission.Key words -litterfall, meteorological variables, phenology, primary productivity, sucession RESUMO -(Padrões de produção de serapilheira em uma Floresta Ombrófi la Densa aluvial secundária no Sul do Brasil). A produção de serapilheira é uma das variáveis mais acessíveis para se estimar a produtividade primária, fl uxos de nutrientes e transferências de carbono em ecossistemas terrestres. Padrões fenológicos e condições climáticas ainda não estão bem explicados para fl orestas tropicais e subtropicais sob climas com sazonalidade pouco pronunciada, muito menos a interação desses padrões com a dinâmica sucessional. A produção mensal de serapilheira foi estimada durante dois anos em uma Floresta Ombrófi la Densa aluvial durante o nono e décimo ano de regeneração. O sítio com vegetação mais desenvolvida apresentou maior produção de serapilheira (6,4 ton ha -1 ano -1 ), quando comparado com o sítio com vegetação menos desenvolvida (3,0 ton ha -1 ano -1 ). As produções mensais de 11 frações de serapilheira foram correlacionadas com variáveis meteorológicas possibilitando identifi car três padrões de deposição.

ABSTRACT:Litter production and decomposition rates have great importance in maintaining the fertility of the soil. The study was carried out to determine the relationship tree characters (girth size, canopy radius, tree height, leaf area and number of primary branches), litter production and quality, and climatic variables among stands of Daniellia oliveri (Rolfe) Hutch. & Dalziel growing in University of Ilorin campus. Twelve trees of different girth sizes were selected and their physiognomic characters measured. Litter samples (leaves and twigs) were collected from the stands on monthly basis (January to May) using 1 m 2 traps. The collected litters were air-dried, ground and analysed for carbon, nitrogen, phosphorus, potassium, calcium and magnesium using standard methods. Rainfall and temperature data were collected during the sampling months. Girth size range was 0.32 -0.67 m. Tree height range was 13.90 -31.81 m. Primary branches range was 3 -16, crown radii was 2.5 -5.2 m and leaflet area between 24.62 cm 2 and 90.90 cm 2 . Higher leaf litter was recorded in January and February, but twigs were more in the other months. Leaf and twig litters positively correlated with girth size (r = 0.572 and 0.614 respectively), but the former also correlated with crown radii (r = 0.834). Carbon, calcium and magnesium contents in leaves and twigs were lower in May compared to January, but reverse trend were observed for nitrogen and phosphorus. The number of rain (rainy days) negatively correlated with total monthly litter (r = -0.291). The study concluded that climatic conditions influence tree characters, which in turn affect litterfall and nutrient returns to the soil. ©JASEM
