Abstract. The Amazon Basin plays key roles in the carbon and water cycles, climate change, atmospheric chemistry, and biodiversity. It has already been changed significantly by human activities, and more pervasive change is expected to occur in the coming decades. It is therefore essential to establish long-term measurement sites that provide a baseline record of present-day climatic, biogeochemical, and atmospheric conditions and that will be operated over coming decades to monitor change in the Amazon region, as human perturbations increase in the future.The Amazon Tall Tower Observatory (ATTO) has been set up in a pristine rain forest region in the central Amazon Basin, about 150 km northeast of the city of Manaus. Two 80 m towers have been operated at the site since 2012, and a 325 m tower is nearing completion in mid-2015. An ecological survey including a biodiversity assessment has been conducted in the forest region surrounding the site. Measurements of micrometeorological and atmospheric chemical variables were initiated in 2012, and their range has continued to broaden over the last few years. The meteorological and micrometeorological measurements include temperature and wind profiles, precipitation, water and energy fluxes, turbulence components, soil temperature profiles and soil heat fluxes, radiation fluxes, and visibility. A tree has been instrumented to measure stem profiles of temperature, light intensity, and water content in cryptogamic covers. The trace gas measurements comprise continuous monitoring of carbon dioxide, carbon monoxide, methane, and ozone at five to eight different heights, complemented by a variety of additional species measured during intensive campaigns (e.g., VOC, NO, NO 2 , and OH reactivity). Aerosol optical, microphysical, and chemical measurements are being made above the canopy as well as in the canopy space. They include aerosol light scattering and absorption, fluorescence, number and volume size distributions, chemical composition, cloud condensation nuclei (CCN) concentrations, and hygroscopicity. In this paper, we discuss the scientific context of the ATTO observatory and present an overview of results from ecological, meteorological, and chemical pilot studies at the ATTO site.

“…A number of factors affect palm community at local and regional scale in tropical forests, such as soil physical and chemical characteristics, topography (slope and altitude), climate, hydrology and components of forest structure (Cintra et al, 2005;Costa et al, 2009;Eiserhardt et al, 2011;Emilio et al, 2014;Rodrigues et al, 2014;Schietti et al, 2014). The greater abundance of palms in forests with a given structure can be a result of specific preferences of the local species (Eiserhardt et al, 2011).…”

“…These forests share higher resemblance in structure than in species composition (Grubb et al, 1963) and identifying structural patterns is a primary goal in plant ecology. Many studies addressed how forest structure varies along successional gradients (Saldarriaga et al, 1988;Brown, 1991;Terborgh and Petren, 1991;Montgomery and Chazdon, 2001;Guariguata and Ostertag, 2001;DeWalt et al, 2003) and how structure is shaped by factors such as topography, soil, water availability, disturbances and previous land use (Grubb et al, 1963;Lieberman et al, 1996;Guariguata and Ostertag, 2001; Thompson et al, 2002;Hietz et al, 2006;Nepstad et al, 2007;Santos et al, 2008;Costa et al, 2010;Emilio et al, 2014;Rodrigues et al, 2014).…”

Palms, bromeliads and bamboos are key elements of tropical forests and understanding the effects of climate, anthropogenic pressure and forest structure on these groups is crucial to forecast structural changes in tropical forests. Therefore, we investigated the effects of these factors on the abundance of these groups in 22 Atlantic forest fragments of Northeastern Brazil. Abundance of bromeliads and bamboos were assessed through indexes. Palms were counted within a radius of 20 m. We also obtained measures of vegetation structure, fragment size, annual precipitation, precipitation seasonality and human population density. We tested the effects of these predictors on plant groups using path analysis. Palm abundance was higher in taller forests with larger trees, closed canopy and sparse understory, which may be a result of the presence of seed dispersers and specific attributes of local palm species. Bromeliads were negatively affected by both annual precipitation and precipitation seasonality, what may reflect adaptations of these plants to use water efficiently, but also the need to capture water in a regular basis. Bamboos were not related to any predictor variable. As climate and forest structure affected the abundance of bromeliads and palms, human-induced climatic changes and disturbances in forest structure may modify the abundance of these groups. In addition, soil properties and direct measurements of human disturbance should be used in future studies in order to improve the predictability of models about plant groups in Northeastern Atlantic Forest.Keywords: Arecaceae, Bambusoideae, Bromeliaceae, disturbance, rainfall, secondary forest fragments. Efeitos do clima e da estrutura da vegetação em palmeiras, bromélias e bambus em fragmentos de Mata Atlântica no nordeste brasileiro ResumoPalmeiras, bromélias e bambus são importantes elementos das florestas tropicais e, entender os efeitos do clima, pressão antrópica e estrutura da floresta nesses grupos é crucial para prever alterações estruturais em florestas tropicais. Portanto, nós investigamos os efeitos desses fatores na abundância desses grupos vegetais em 22 fragmentos de Mata Atlântica no nordeste brasileiro. Abundâncias de bromélias e bambus foram registradas através de índices. Palmeiras foram contadas em um raio de 20 m. Nós também obtemos medidas da estrutura da vegetação, tamanho de fragmento, precipitação anual, sazonalidade na precipitação e densidade populacional humana. Nós testamos os efeitos desses preditores nos grupos vegetais através de análises de caminhos. A abundância de palmeiras foi maior em florestas mais altas, com árvores mais grossas, dossel fechado e sub-bosque aberto, o que deve refletir a presença de dispersores de sementes e atributos específicos das espécies de palmeiras locais. Bromélias foram negativamente afetadas pela precipitação anual e pela sazonalidade na precipitação, o que deve refletir adaptações dessas plantas para o uso eficiente da água, mas também a necessidade de captar água regularmente.

“…For example, Euterpe is the most abundant 55 tree genus across the entire Amazon, and Euterpe precatoria and E. oleracea are the most and seventh most abundant hyperdominant tree species, respectively (Ter Steege et al, 2013). Arborescent palms also represent a dominant proportion of tree basal area and biomass in central and western Amazon forests (Vormisto et al, 2004;Emilio et al, 2014), but they appear to be less dominant in eastern Amazonia, including areas of 60 the Guianan Shield (Terborgh and Andresen, 1998). Yet even when palms are less dominant and/or less abundant, they can still provide a disproportionate contribution to forest and cultural dynamics due to extended fruiting seasons and high levels of fruit production (Peres, 2000;Link and De Luna, 2004;Cámara-Leret et al, 2014).…”

Highlights The occurrence, density and biomass of adult arborescent palms were measured in a National Forest in the eastern Brazilian Amazon. Commercially important arborescent palms were rare. Density and biomass were related to hydrographic and topographic variables. Subsidised agroforestry practices are required to facilitate the commercialization of palm NTFPs. Published as:Norris, D., Chuma, V.J.U.R., Arevalo-Sandi, A.R., Paredes, O.S.L. and Peres, C.A., 2016. Too rare for non-timber resource harvest? Meso-scale composition and distribution of arborescent palms in an Amazonian sustainable-use forest. Forest Ecology and Management, 377,. oleracea, an economically important species. The presence, biomass, and density of palms were uncorrelated with geographic distances among plots. The hydrographic model significantly explained variation in palm presence and biomass, whereas density was only explained by the topographic model. Our findings indicate that arborescent palms are currently too rare to be efficiently harvested as NTFPs in the study area. Yet, comparisons with published estimates suggest that there is significant potential for agroforestry to facilitate the commercialization of palm NTFPs for community based extractive activities.
