“…Higher values for soil microbial biomass and activity were observed at CSS and CD and may be associated with the greater plant richness and diversity found at these sites, which provides a high quantity and quality of plant litter that contributes to the higher availability of above-and below-ground carbon sources for soil microbial biomass (Nsabimana et al, 2004). According to Ribeiro et al (2011), the above-ground biomass in the Brazilian Cerrado varied from 12.8 to 107.3 ton ha -1 , while the estimation of below-ground biomass ranged from 15.0 to 102.1 ton ha -1 in the grassland and Cerradao, respectively. Therefore, these differences in the litter contribution influenced the soil microbial biomass across the gradient.…”

The different physiognomies and soil conditions across the Cerrado gradient may influence soil microbial biomass. The present study evaluated the soil microbial biomass and enzyme activity across a preserved Cerrado gradient and correlated these with environmental conditions. The site, sampling period and their interaction influenced soil microbial biomass and activity. Soil conditions, i.e., chemical and microclimatic properties, varied across the Cerrado gradient and influenced soil microbial biomass and activity. The highest and lowest values for microbial biomass and enzyme activity were found in Cerradao and Campo graminoide, respectively, during both seasons. Multivariate analysis showed that the sites were clearly separated into different groups, indicating that distinct physiognomies and environmental conditions influenced soil microbial biomass and enzyme activities.

“…Valores de precipitação pluviométrica e estoque mensal de serapilheira em áreas de Cerrado Típico, Mata de Galeria e povoamento de eucalipto na Fazenda Água Limpa, UnB, Lago Sul, DF. (Ribeiro et al, 2011). Segundo Ribeiro & Walter (2008), em Matas de Galeria o estrato arbóreo apresenta altura entre 20 m e 30 m, na qual observa-se uma superposição das copas, que fornecem cobertura arbórea de 70% a 95%.…”

Estoque de Serapilheira em Três Fisionomias no Cerrado do Distrito Federal

et al. 2017

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.

“…For example, it is not always obvious if a basic variable such as "tree height" refers to total tree height or to commercial tree height (e.g. Feldpausch et al 2010or Ribeiro et al 2011. Information about the height where the diameter measurement was taken is needed.…”
