Abstract

Structure and floristic composition will be determined in the following Atlantic Forest types: Low Land Ombrophylus Dense Forest (5 to 50 m above sea level), Sub Montana Ombrophylus Dense Forest (50 to 500 m above sea level), and Montana Ombrophylus Dense Forest (500 to 1.200 m above sea level). All trees with a DBH > 4,8 cm that fall inside 14 1ha permanent plots, divided into a grid of 10 x 10 meter parcels, will be considered.The 14 permanent plots will be established along the altitudinal gradient, 4 independent plots in each forest type plus 1 plot of Restinga Forest (sand dunes type of forest) and extra 1 plot of Low Altitude Ombrophylus Dense Forest. In the case of botanical families with relevant ecological roles, such as the Leguminosae in the nitrogen cycle, or Bromeliaceae, Melastomataceae, Rubiaceae, Solanaceae,Moraceae and Piperaceae responsible for the maintenance of key populations of pollinators and dispersors, a comprehensive floristic survey will include herbaceous, lianas and epiphytes. Data analysis will be conducted using the FITOPAC program. Where appropriate, more detailed analyses will be conducted using multivariate methods such as Canonical Correlation, Correspondence Analysis, PCA and PCO. The database on composition and structure of the forest will allow a choice of species for more detailed studies on reproduction biology, seed anatomy and reserves, germination, photosynthesis and water use efficiency, nitrogen assimilation, transport and metabolism, plant populations structure and dynamics, techniques, genetic structure of plant populations using molecular markers, determination of forest age by DBH classes and using 14C, determination of annual average growth rates of key species, and phenology. Multivariate analyses will be used to check for functional groups, or groups of species that share a common behavior and ecology. The comparison of different groups along the altitudinal gradient will allow investigation of the effect of altitude in the functioning of these groups. Simultaneously, the inputs of nitrogen through precipitation, biological fixation, and soil mineralization and nitrification will be determined, along with key parameters of N losses through desnitrification and export by streams, allowing a preliminary nitrogen mass balance along the altitudinal gradient. Water and carbon balance of the forest will be estimated along with the seasonal variation of this balance through use of micrometeorological towers and Eddy-covariance technique. The photosynthesis/respiration balance of the ecosystem will be used to determine the role of the forest as a sink or source of carbon to the atmosphere. Our final goal is to integrate the results of all activities listed above, scaling-up from individual trees, to families, o functional groups, and finally to phytophysiognomies, allowing us to understand forest structure and functioning. The outcomes of this project will allow, for the first time, a full comparison between the Atlantic ODF and the Amazon ODF, and will enhance our capability in understanding how this biome will respond to future climatic changes.
