“…The authors showed that trees respond to it by producing foliage with a higher degree of sclerophylly and by maintaining larger fine root systems. Martius et al (2004) found that higher temperatures and lower soil moisture in younger forests under a developing canopy may contribute to slower decomposition rates, which reinforces the hypothesis of higher soil moisture and higher decomposition rate found in this study during the time of litterbag exposition.…”

Litter fall consists of all organic material deposited on the forest floor, being of extremely important for the structure and maintenance of the ecosystem through nutrient cycling. This study aimed to evaluate the production and decomposition of litter fall in a secondary Atlantic forest fragment of secondary Atlantic Forest, at the Guarapiranga Ecological Park, in São Paulo, SP. The litter samples were taken monthly from May 2012 to May 2013. To assess the contribution of litter fall forty collectors were installed randomly within an area of 0.5 ha. The collected material was sent to the laboratory to be dried at 65 °C for 72 hours, being subsequently separated into fractions of leaves, twigs, reproductive parts and miscellaneous, and weighed to obtain the dry biomass. Litterbags were placed and tied close to the collectors to estimate the decomposition rate in order to evaluate the loss of dry biomass at 30, 60, 90, 120 and 150 days. After collection, the material was sent to the laboratory to be dried and weighed again. Total litter fall throughout the year reached 5.7 Mg.ha-1.yr-1 and the major amount of the material was collected from September till March. Leaves had the major contribution for total litter fall (72%), followed by twigs (14%), reproductive parts (11%) and miscellaneous (3%). Reproductive parts had a peak during the wet season. Positive correlation was observed between total litter and precipitation, temperature and radiation (r = 0.66, p<0.05; r = 0.76, p<0.05; r = 0.58, p<0.05, respectively). The multiple regression showed that precipitation and radiation contributed significantly to litter fall production. Decomposition rate was in the interval expected for secondary tropical forest and was correlated to rainfall. It was concluded that this fragment of secondary forest showed a seasonality effect driven mainly by precipitation and radiation, both important components of foliage renewal for the plant community and that decomposition was in an intermediate rate.

“…A serapilheira representa a reserva central de elementos minerais e orgânicos em ecossistemas de florestas tropicais, onde os solos são quimicamente pobres e sua decomposição possibilita que os elementos liberados da biomassa vegetal entrem no sistema (Martius et al 2004). A importância de se avaliar essa produção está na compreensão dos reservatórios e fluxos de nutrientes nos ecossistemas, os quais constituem-se na principal via de fornecimento de nutrientes, por meio da mineralização dos restos vegetais, desempenhando importante papel na formação e manutenção da fertilidade do solo, bem como na oferta de matéria orgânica para a flora e fauna local (Souza & Davide 2001).…”

Foram estudados dois trechos de vegetação ciliar na região do Alto São Francisco, Minas Gerais, com o objetivo de verificar diferenças na produção de serapilheira. A serapilheira foi coletada entre setembro/2001 e agosto/2002, utilizando-se 10 coletores de 0,25 m 2 em cada trecho. Os resultados obtidos demonstraram uma produção elevada de serapilheira em ambos os trechos de mata, sendo que as folhas predominaram sobre os ramos e estes sobre os órgãos de reprodução nos dois talhões. A mata nativa apresentou um comportamento sazonal de queda de serapilheira, se contrapondo ao reflorestamento, que não apresentou sazonalidade para a queda de serapilheira. Os resultados obtidos estão de acordo com os valores próprios das matas localizadas sobre planícies aluvionares tropicais. Foram encontradas grandes diferenças entre os períodos de maior produção de serapilheira entre a mata ciliar nativa e a reflorestada, para o que estariam agindo de forma conjunta à dinâmica a florística e o estádio sucessional das espécies existentes nos trechos de vegetação estudados.Palavras-chave: mata ciliar, reflorestamento, bacia do rio São Francisco, recuperação de áreas degradadas, conservação.

“…The return of mineral elements through litter decomposition and mineralization is particularly relevant where soils are chemically poor, like most tropical forest ecosystems (Vitousek & Sanford, 1986;Martius et al, 2004). As a result, litter influences the plant community structure in these ecosystems (Facelli & Pickett, 1991;Molofsky & Augspurger, 1992).…”

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.
