“…Segundo Clark (2001), A. aristulata é caracterizada por apresentar rizoma anfimorfo (ver Judziewicz et al 1999), colmos decumbentes ou escandentes com 1-4 m, entrenós ocos, e nós no meio do colmo com uma gema, resultando no complemento de um só ramo dominante, portando na base 2 a muitos ramos bem desenvolvidos e livres. Dessa forma, lianas podem ter seu crescimento suprimido pela competição por bambus (Campanello et al 2007) na área I, dominada pelo bambu.…”

-(Liana abundance and biomass in an Atlantic forest fragment). Lianas represent an important component of the structure and diversity of tropical forests. Normally, in disturbed forest a higher density and biomass of lianas is found compared with undisturbed forests. The aim of this study was to evaluate if the abundance and biomass of lianas differ between bamboo-dominated and non-dominated areas in Parque Estadual das Fontes do Ipiranga. Sample plots of 0.7 ha were established in both areas, and a standard census protocol for woody lianas ≥ 1 cm were used. We found 277 lianas (395 ind. ha ) in the non-dominated area. The biomass, abundance and the proportion of infested trees were significantly different between areas. Lianas ≥ 5 cm diameter accounted for 75% of total biomass in the bamboo-dominated area and 21,4% in the non-dominated area. In bamboo-dominated area lianas may be suppressed by absence of supports and by competition with Aulonemia aristulata a native scandent bamboo. Key words: Aulonemia aristulata, bamboo, forest fragment, lianas biomass RESUMO -(Abundância e biomassa de lianas em um fragmento de floresta Atlântica). Lianas representam um importante componente da estrutura e diversidade das florestas tropicais. Normalmente em florestas perturbadas são encontradas uma alta densidade de lianas em comparação com florestas não perturbadas. O objetivo deste estudo foi avaliar se a abundância e a biomassa de lianas difere entre áreas dominadas e não-dominadas por uma espécie de bambu nativo no Parque Estadual das Fontes do Ipiranga. Uma parcela de 0,7 ha foi estabelecida em cada área e um censo com protocolo padrão para lianas lenhosas ≥ 1 cm foi usado. Nós encontramos 277 lianas (395 ind. ha ) na área não dominada. A biomassa e a proporção de árvores infestadas foram diferentes entre áreas. Lianas ≥ 5 cm de diâmetro foram responsáveis por 75% da biomassa total na área dominada por bambu e por 21,4% na área não dominada por bambu. Na área dominada por bambu as lianas podem ter sido suprimidas pela ausência de suporte e pela competição com Aulonemia aristulata um bambu nativo escandente.

“…Several authors associate the reduced biomass of western Amazonian forests to the presence of bamboo [64][65][66]. Bamboo tends to reduce density and basal area of trees [67,68], restraining forest biomass development due to a negative feedback with the recruitment, growth, and survival of other individuals [69,70]. Tree recruitment is suppressed by the low density of seedlings and saplings [71][72][73][74].…”

Abstract:Fire is one of the main factors directly impacting Amazonian forest biomass and dynamics. Because of Amazonia's large geographical extent, remote sensing techniques are required for comprehensively assessing forest fire impacts at the landscape level. In this context, Light Detection and Ranging (LiDAR) stands out as a technology capable of retrieving direct measurements of vegetation vertical arrangement, which can be directly associated with aboveground biomass. This work aims, for the first time, to quantify post-fire changes in forest canopy height and biomass using airborne LiDAR in western Amazonia. For this, the present study evaluated four areas located in the state of Acre, called Rio Branco, Humaitá, Bonal and Talismã. Rio Branco and Humaitá burned in 2005 and Bonal and Talismã burned in 2010. In these areas, we inventoried a total of 25 plots (0.25 ha each) in 2014. Humaitá and Talismã are located in an open forest with bamboo and Bonal and Rio Branco are located in a dense forest. Our results showed that even ten years after the fire event, there was no complete recovery of the height and biomass of the burned areas (p < 0.05). The percentage difference in height between control and burned sites was 2.23% for Rio Branco, 9.26% for Humaitá, 10.03% for Talismã and 20.25% for Bonal. All burned sites had significantly lower biomass values than control sites. In Rio Branco (ten years after fire), Humaitá (nine years after fire), Bonal (four years after fire) and Talismã (five years after fire) biomass was 6.71%, 13.66%, 17.89% and 22.69% lower than control sites, respectively. The total amount of biomass lost for the studied sites was 16,706.3 Mg, with an average loss of 4176.6 Mg for sites burned in 2005 and 2890 Mg for sites burned in 2010, with an average loss of 3615 Mg. Fire impact associated with tree mortality was clearly detected using LiDAR data up to ten years after the fire event. This study indicates that fire disturbance in the Amazon region can cause persistent above-ground biomass loss and subsequent reduction of forest carbon stocks. Continuous monitoring of burned forests is required for depicting the long-term recovery trajectory of fire-affected Amazonian forests.

“…Como esperado, identificou-se, para as plântulas padrão, similar ao detectado para as sementes, com maior densidade destas na borda das clareiras. Esse grupo de plantas se espalha rapidamente através de rizomas paquimorfos, formando densas touceiras com profusão de colmos pendentes (CAMPANELLO et al, 2007). Dada a sua localização mais densa nos limites externos da clareira, uma das implicações possíveis desse padrão de recolonização e crescimento seria o aumento da área de ocupação atual da espécie, resultado em um ciclo de distúrbio autoperpetuado.…”
