“…The representativeness of these families as hosts is understandable, since these are the most diverse and abundant families according to various floristic surveys in the Amazon, although these studies do not associate them with the epiphytic community (Amaral et al 2000;Duque et al 2003;Oliveira et al 2008;Silva et al 2008). This result may indicate that epiphytes occurred more frequently on these phorophytes because these species possess a wide distribution, as well as high density in terra firme forests in the Amazon and, therefore, the majority of available species and individuals in this forest may be conducive to epiphytic colonization.…”

10 cm) were sampled. We recorded 3.528 individuals in 13 families, 48 genera and 164 species. Araceae was the most prevalent family with regard to the importance value and stood out in all related parameters, followed by Bromeliaceae, Cyclanthaceae and Orchidaceae. The species with the highest epiphytic importance values were Guzmania lingulata (L.) Mez. and Philodendron linnaei Kunth. The predominant life form was hemiepiphytic. Estimated floristic diversity was 3.2 (H'). The studied epiphytic community was distributed among 727 host plants belonging to 40 families, 123 genera and 324 species. One individual of Guarea convergens T.D. Penn. was the host with the highest richness and abundance of epiphytes. Stems/trunks of host plants were the most colonized segments, and the most favorable habitat for epiphytism was the lowlands, where 84.1% of species and 48.2% of epiphytic specimens were observed.]]>

“…O percentual de espécies raras encontrado pode ser considerado baixo por se tratar de uma floresta intacta, ou seja, ainda não manejada, principalmente em relação a alguns estudos realizados na Amazônia Legal: 44% em Oliveira et al (2003) e 49% em Silva et al (2008). Porém cabe salientar, que a intensidade amostral foi de apenas 0,05% da área de manejo florestal e pode não refletir a quantidade total de espécies raras presentes nessa floresta.…”

RESUMOO presente estudo teve como objetivo caracterizar a composição florística e fitossociológica de uma floresta nativa no município de Caracaraí, Roraima, Brasil. Foram inventariadas todas as árvores com DAP > 10 cm em 9 parcelas permanentes de 100 x 100 m (1 ha cada Phytosociology of a dense ombrophilous forest in the northern Amazon, Roraima, Brazil ABSTRACTThis study was carried out to characterize species composition and phytosociology of a native forest located at Caracaraí, Roraima, Brazil. All trees with breast diameter (DBH) above 10 cm in nine 1-ha-permanent plots (100 x 100 m each) were inventoried. We observed 4,724 individuals (525 trees per hectare) distributed in 42 families, 111 genera and 165 species. The families with greater number of individuals were Fabaceae (1883), Lecythidaceae (609) and Sapotaceae (434), comprising 52% of the total. The higher densities of individuals were observed in the pioneer (219 trees ha -1 ), followed by secondary (193 trees ha ). However, species of secondary group had the highest species richness (95), followed by the climax (44) and the pioneer (26). The Shannon diversity index (H' = 3.27) and the value of Pielou equability (J = 0.64) were lower than those obtained in other floristic inventories in the Amazon, because of the high occurrence of Pentaclethra macroloba. The importance values (VI) were higher for Pentaclethra macroloba (52.1), Eschweilera bracteosa (23.7) and Pouteria caimito (8.1). The importance values of these three species alone accounted for 28% of the total VI across species. Most of the individuals (71.3% = 374 trees ha -1 ) were recorded in the middle stratum (12.4 m < height < 26.5 m) of forest. The forest community can be considered well-structured, mature and diverse, and so it is in good state of conservation.

RESUMOEste trabalho analisou dados de três inventários florestais realizados na área da Floresta Experimental, pertencente à Embrapa Amazônia Ocidental e localizada no km 54 da BR-174, em Manaus/AM. O objetivo foi estudar a dinâmica da floresta -taxas de incremento, recrutamento e mortalidade -além do estoque de carbono, em uma área de floresta primária, sem qualquer tipo de intervenção. Dynamics and carbon storage in primary forest in the region of Manaus / AM ABSTRACTThis study analyzed data from three forest inventories conducted in the Experimental Forest, which belongs to Embrapa Western Amazon basin and is located at km 54 on BR-174, Manaus / AM. The aim was to study forest dynamics -the rates of recruitment, growth and mortality -in addition to carbon storage in an area of primary forest, without any intervention. The surveys were conducted in the years 2005, 2007 and 2010 in 15 permanent plots of 1 hectare each. There, all trees with diameter at breast height (DBH) above 10 cm were measured. We calculated the rates of recruitment and mortality, the periodic annual increments (PAIs) in terms of DBH, basal area and volume, fresh and dry biomass above the soil and total carbon storage in the vegetation. The recruitment rates were 2.0 percent and 1.8 percent, and mortality were 0.
