Natural regeneration in a quaternary coastal plain in southern Brazilian Atlantic Rain forest BABT
Salimon,Cleber Ibraim; Negrelle,Raquel R. B..
Composition, structure and dynamics of an eight year old secondary forest was studied at Reserva Volta Velha (26°04'S; 48°38'W), southern Brazil. A 0.72ha plot was divided into 36 subplots of 20X10m, where all trees/shrubs greater than 1m tall were identified, measured (height/diameter) and evaluated (successional status). The results were: (1) 95 species collected within 68 genera and 44 families; the most species rich families were Myrtaceae and Asteraceae with 8 species each; (2) the most important species (considering biomass and density) were Psidium cattleianum, Eupatorium casarettoi, Ocotea pulchella and Ternstroemia brasiliensis; (3) the most similar area was a fallow abandoned 35 years ago; (4) the higher species diversity were found in border...

Tree mortality, recruitment and growth in a bamboo dominated forest fragment in southwestern Amazonia, Brazil Biota Neotropica
Medeiros,Herison; Castro,Wendeson; Salimon,Cleber Ibraim; Silva,Izaias Brasil da; Silveira,Marcos.
Forest fragmentation affects the structure and dynamics of plant communities, leading to biodiversity loss in forest remnants. In this paper we show that in a bamboo (Guadua weberbaueri Pilger) dominated forest fragment in southwestern Amazonia edge effect may be confounded by bamboo effect, which also occur inside the forest. We measured growth, mortality and, recruitment rate of trees with DBH ≥ 10 cm, in a fragment of bamboo dominated open forest in southwestern Amazonia, state of Acre, Brazil, in 15 plots at the forest edge and 15 plots inside the forest fragment, 500 m away from the border. Time interval between censuses was 1.8 years. The average diameter growth rate differed significantly between edge (3.82 ± 0.10 mm a-1) and interior (2.39 ± 0.18...
