This proposal aims to meet the urgent need to extend monitoring of biodiversity, carbon stock, carbon balance, tree growth, and tree mortality in Latin America beyond rain forests and into dry biomes. Most concerns about biodiversity and ecosystem function in the tropics focus on rain forests, but this neglects the fact that 50% of the lowland tropics globally is climatically seasonal, with a natural vegetation of dry forest or savanna. In South America in particular, the rain forests of Amazonia monopolise research and conservation, but dry forests and woody savannas can house equal numbers of plant species, many of which are endemic. We need to understand far better how these dry biomes contribute to global biogeochemical cycles and how their unique species react to environmental changes. In particular, little is known about how dry forests will respond to climate change.Initiatives such as RAINFOR have been highly successful in connecting a large network of scientists who have established permanent inventory plots in Neotropical rain forests. Collectively, hundreds of plots distributed across Amazonia have been central to describing patterns of biodiversity across the basin, and how the forest participates in global biogeochemical cycles. No corresponding network connecting a large number of plots over broad geographic scales exists in Brazil or more widely in the Neotropics for dry biomes. This project aims to start a process of connecting researchers who have established dozens of inventory plots in these biomes.We propose to:1. Re-census, using methodologies agreed by the RAINFOR network, 10 permanent 0.2Ha plots in tropical dry forest in Rio de Janeiro state for carbon stock, above ground biomass (C) gain, tree growth, tree mortality, and biodiversity. 2. Contribute data for five existing 1 Ha plots in dry forests and neighbouring forest biomes in Rio de Janeiro state and c. 100 dry forest plots from elsewhere in Brazil to the ForestPlots.net database, thereby making it available to the global research community. We will prioritise dry forests, but we also have plot-based data from the Mata Atlântica rain forests (not covered by RAINFOR), and from the tree-savanna biome of the cerrado in Central Brazil, and we hope additionally to start a process of adding this information to ForestPlots.net. 3. Convene a workshop to bring together key workers from RJ and across Brazil who have established inventory plots in dry biomes to encourage them to join a new network that can take forward dry forest monitoring at a continental scale. This workshop will be held in the Universidade Estadual do Norte Fluminense (UENF), Campos dos Goytacazes, RJ, Brazil. This workshop will be preceded by a two day training course in phylogenetics and phylogenetic diversity delivered by Dexter and Pennington at the Escola de Botânica in Rio, and will be followed a course for the same student pool on ecological niche modelling taught by Antje Ahrends (Royal Botanic Garden Edinburgh). In addition, training will be provided to Brazilian co-Is in the UK to build capacity to make some simple growth, leaf area and respiration measurements, led by Meir and Grace, with plot curation and analysis training using the ForestPlots.net facility, led by Gabriela Lopez in Leeds.4. Compare phylogenetic diversity between dry forests and neighbouring rain forests in RJ to determine if these dry forests house unique lineage diversity, thereby adding a further argument for their conservation (7). Additionally, we will examine the impact of landscape history and fragmentation on phylogenetic diversity and phylogenetic community structure in these dry forests. 5. We will develop a database of key functional traits, environmental parameters and principal carbon stocks and fluxes, and of the structure, floristics and phylogeny of Atlantic tropical semi-deciduous seasonal forest.

该提案旨在满足迫切需要扩展对拉丁美洲的生物多样性，碳库存，碳平衡，树木生长和树木死亡率的监测，而不是雨林之外的生物群落。最担心的是热带森林中生物多样性和生态系统功能，但这忽略了这样一个事实，即全球50％的低地热带地区是气候季节性的，具有干燥森林或稀树草原的天然植被。特别是在南美，亚马逊山的雨林垄断了研究和保护，但是干燥的森林和木质稀树草原可以容纳相等数量的植物物种，其中许多物种是内在的。我们需要更好地了解这些干燥生物群落如何促进全球生物地球化学周期以及它们独特物种对环境变化的反应。特别是，关于干燥森林将如何应对气候变化的鲜明的了解。总体而言，分布在亚马逊地区的数百个地块对于描述整个盆地的生物多样性模式以及森林如何参与全球生物地球化学周期是至关重要的。在巴西，没有相应的网络连接大量的地理量表，或在新型生物群体的新型中广泛存在。该项目旨在启动连接已经在这些生物群落中建立数十个库存图的研究人员联系的过程。我们建议：1。重新计算，使用Rainfor Network商定的方法学，在里约热内卢州的热带干燥森林中有10个永久性0.2公顷地块用于碳库存，高于地面生物量（C）增益，树木生长，树木死亡率和生物多样性。 2。在里约热内卢州立大学和c的邻近森林和邻近的森林生物群落中贡献了五个现有的1公顷图。 100个从巴西其他地方到Forestplots.NET数据库的干森林地块，从而向全球研究界提供了。我们将优先考虑干燥的森林，但是我们还拥有来自MataAtlântica雨林（不被Rainfor覆盖）以及巴西Cerrado的Tree-Savanna Biome的基于情节的数据，我们希望还可以启动将此信息添加到Forestplott.net的过程。 3.召开研讨会，将来自RJ和整个巴西的主要工人汇集在一起​​，他们在干燥的生物群落中建立了库存，以鼓励他们加入一个新的网络，该网络可以连续进行干燥的森林监测。该研讨会将在巴西RJ的Campos dos Goytacazes，Campos do fluminense（UENF）大学举行。在此研讨会之前，Dexter和Pennington在里约热内卢的Escola deBotânica提供了为期两天的系统发育和系统发育多样性的培训课程，并将遵循与Antje Ahrends（Royal Botanic Garden Edinburgh）进行生态基础化教学的同一学生池的课程。此外，将向英国的巴西合作社提供培训，以建立由Meir和Grace领导的简单增长，叶子区域和呼吸测量的能力，并使用Forestplots.net设施进行情节策划和分析培训，由Gabriela Lopez领导，LEEDS.4。比较RJ干燥森林和邻近的雨林之间的系统发育多样性，以确定这些干林是否可以容纳独特的谱系多样性，从而增加了对其保护的进一步论据（7）。此外，我们将研究景观历史和破碎化对这些干林中系统发育多样性和系统发育群落结构的影响。 5。我们将开发一个数据库，包括关键功能性状，环境参数以及主要的碳储备和通量，以及大西洋热带半凝乳季节森林的结构，植物和系统发育。
