A B S T R A C TThe material that is deposited throughout the year in forests has an important role in litter formation, especially in environments under stress, as occurs in the semi-arid. This study aimed to identify the inference of the vegetation cover in the production of leaf litter in tropical dry forest-Caatinga. The study was developed in the catchment area of the Alto Jaguaribe in Iguatu-CE. It was monitored two sub-basins, one with vegetation cover of caatinga in regeneration about 38 years, and another one under thinning management, maintaining the plant species with stem circumference ≤ 10 cm. Litter samples were taken monthly (January 2011 to December 2013). It was used 15 boxes of 1 m 2 randomly arranged in each hydrographic watershed. The average amount of leaf litter produced plots with regenerating and thinned caatinga were of the order of 4,277.2 and 2,248.0 kg.ha , respectively. Litter production presented a seasonal character, with peak production immediately after the rainy season, producing respectively 62.1% and 47.9% of all litter in the months of May to September. It shows that the caatinga in higher regeneration due to output the most individuals' ferns and most amount of species.

“…In productive forest ecosystems, such as in natural stands of Brazil nut trees (Bertholletia excelsa Bonpl. ), a species native to the Amazon and of great importance to economic sustainability of the region (Salomão, 2014), the study of litter production can help to understand the nutrient dynamics in these stands (Lima et al, 2015;Proctor, 1983) and direct management techniques. Godinho et al (2014) also emphasize the importance of quantifying litter production in pristine ecosystems that are threatened by human activities, such as the case of stands of native Brazil nut trees along the BR 163 (Santarém-Cuiabá) highway (Scoles et al, 2016).…”

This research estimated litter production and analyzed its relation to environmental variables such as maximum temperature, insolation, and rainfall. The study was conducted on a 300 × 300 m experiment as part of the project titled mapping of native Brazil nut stands and socio-environmental and economic characterization of Brazil nut production systems (MapCast), in the Tapajós National Forest (FLONA Tapajós). Every 30 days for one full year (August 2015 to July 2016), litterfall was collected and stored in a laboratory. After drying, the material was separated into leaves, wood, flowers and fruits, and miscellaneous and weighed. Statistical tests conducted were Shapiro-Wilk (5%), Principal coordinate analysis, t-test, Pearson's linear correlation, cross-correlation, and canonical redundancy analysis. Rainfall and temperature data were inferior and superior, respectively, to normal climate conditions in the region, and data for solar insolation had an abnormal pattern compared to normal climate conditions. Leaf production varied between 169.9 and 965.6 kg ha . The greatest leaf production was measured during the months with the lowest amount of rainfall and highest temperatures, and variation in leaf production and total litterfall was partially explained by temperature and insolation.

“…Padrão oposto ocorreu na Mata de Galeria, onde a fração foliar apresentou maior contribuição para o estoque de serapilheira durante o período de maior precipitação (Figuras 1 e 3). Vários estudos sugeriram que o padrão de maior queda da serapilheira na estação seca, o qual reflete-se no aumento do estoque de serapilheira nesse período, é um mecanismo pelo qual a vegetação arbórea minimiza perdas de água via evapotranspiração durante a época de estiagem, na qual ocorre déficit hídrico (Moreira & Silva, 2004;Andrade et al, 2008;Lima et al, 2015;Silva et al, 2007;Vital et al, 2004). Já o maior estoque de serapilheira na estação chuvosa foi verificado para a Mata de Galeria, o que provavelmente ocorreu em função da maior queda de folhas e, em alguns casos, de galhos, o que geralmente ocorre em florestas sem restrição hídrica severa durante a estação chuvosa.…”

RESUMOO estudo teve como objetivo avaliar o estoque mensal e anual de serapilheira e sazonalidade em duas fitofisionomias (Cerrado stricto sensu e Mata de Galeria) e em um povoamento de eucalipto, localizados na Fazenda Água Limpa, DF. O estoque de serapilheira foi coletado mensalmente, pelo período de um ano, com auxílio de um gabarito metálico de 0,25 m 2 . O material foi separado manualmente nas frações folhas, cascas, galhos, raízes, flores/frutos e material particulado. O estoque de serapilheira na Mata de Galeria (9,36 t ha -1 ) foi estatisticamente igual ao observado no povoamento de eucalipto (9,12 t ha -1 ), valores maiores que o verificado no Cerrado Típico (6,08 t ha -1 ). A fração folha apresentou maior quantidade nas fitofisionomias e no povoamento quando comparada às demais frações. Verificaram-se dois padrões divergentes de sazonalidade do estoque de serapilheira: maior estoque no Cerrado Típico e no povoamento de eucalipto na estação seca e maior estoque na Mata de Galeria na estação chuvosa.Palavras-chave: ecologia florestal, senescência foliar, sistemas florestais. Litter Stock in Three Forest Types in Cerrado at Distrito Federal ABSTRACTThe aim of this study was to evaluate the monthly and annual litter stock, and the seasonality in two phytophysiognomies (Cerrado stricto sensu and Gallery Forest) and one eucalyptus plantation, located in Fazenda Água Limpa, DF. The litter stock was monthly collected by using a metal jig of 0.25 m 2 , during one year. The material was manually sorted into leaves, bark, twigs, roots, flowers/fruits and particulate matter. There were no significant differences in the litter stock between the Gallery Forest (9.36 t ha -1 ) and the eucalyptus plantation (9.12 t ha -1 ), which were both higher than the Cerrado stricto sensu (6.08 t ha -1 ). The leaf fraction presented a larger amount in the three vegetation types when compared to the other fractions. There were two different patterns of litter stock seasonality: higher litter stock in the Cerrado stricto sensu and eucalyptus plantation in the dry season; and higher stock in Gallery Forest in the rainy season.
