- Abstract
-This study aimed to assess the seasonality of litter deposition in a Cerrado area, in Gurupi, Tocantins State, Brazil. We installed systematically 50 collectors in the area. Litter collections were carried out monthly for two years from July, 2016 to June, 2018. The litter was collected and packed in plastic bags, before separating the fractions (leaves, branches and reproductive material). Subsequently, the samples were taken to the oven at 70 °C for 48 h. The litter deposition varied in terms of stability along the two years, with higher production in the dry period. The total litter production and its structural and reproductive and leaf fractions were not affected by the differences between years 1 (5,884.0 kg ha-1) and 2 (5,420.0 kg ha-1), only for branches that presented significant differences. We measured 426 individuals distributed in 40 species and 28 families, showing Shannon diversity index equivalent to 3.11 (nats ind-1) and Pielou equitability index of 0.84. The species Myrcia splendens showed higher values for phytosociological parameters. There were significantly correlations among growth traits and the fraction of leaf and branches.
