Última Forest biomass and wood consumption In the lower course of the Amazon: a case study of rhe Urubueua Island Acta Amazonica TSUCHIYA,Akio; HIRAOKA,Mario. Várzea and terra-firme forests in the lower course of the Amazon were compared in terms of forest structure, wood volume increments and forest biomass. The wood volume of várzea forests was smaller than that of terra-firme forests, particularly when severe human intervention such as the cultivation of açaí palm occurred. The difference was even greater in the forest weight comparison because of the lower wood density of várzea trees. These trees are not directly influenced by water stress during the dry season, while late wood with a high density is formed in the terra-firme trees. The annual forest disappearance area due to firewood for tile factories was estimated to be about 276 ha on the island investigated, which had an area of 36,200 ha. Assuming...

Ano: 1999 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0044-59671999000100079 The relationship between stem vessel parameters and the development of strata in the early stages of secondary forest succession in Amazonia Acta Amazonica TSUCHIYA,Akio; HIRABUKI,Yoshihiko; NISHIZAWA,Toshie; LISBOA,Pedro Braga; SILVA,Carlos Rosário da. In order to compare the development of strata in the early stages of secondary forest succession with vessel parameters of the tree species, a forest inventory was carried out in 4-year (Q1: 48 m2), 11-year (Q2: 400 m2) and 20-year (Q3: 400 m2) forests and vessel parameters were investigated from stem cross sections of 18 species obtained in Q2. Thirty three species (21 families), 77 species (35 families), 39 species (20 families) were found in Ql, Q2, Q3, respectively. The percentage of dead individuals, dead stems and the percentage of individuals with multiple stems increased with time after clear cutting. Also, the total D2H of Q3 was 26.1 times that of Q1, and the development of strata started in Q2 and Q3. The image analysis of vessel size, area and...
