Building bridges between environmental and political agendas is essential nowadays in face of the increasing human pressure on natural environments, including wetlands. Wetlands provide critical ecosystem services for humanity and can generate a considerable direct or indirect income to the local communities. To meet many of the sustainable development goals, we need to move our trajectory from the current environmental destructive development to a wiser wetland use. The current article contain a proposed agenda for the Pantanal aiming the improvement of public policy for conservation in the Pantanal, one of the largest, most diverse, and continuous inland wetland in the world. We suggest and discuss a list of 11 essential interfaces between science, policy, and development in region linked to the proposed agenda. We believe that a functional science network can booster the collaborative capability to generate creative ideas and solutions to address the big challenges faced by the Pantanal wetland.

The floristic composition (trees) of 26 forests in the state of S~o Paulo, Brazil, was compared using cluster analysis and Principal Coordinates Analysis (PCO) with simple Euclidean distance. The results obtained indicate the existence of two floristically distinct groups of forests. One group contains forests from higher areas (above 700 m) with a colder climate (Cfa and Cfb) and includes surveys from Angatuba, Atibaia, Guarulhos, Jundiaf, S~o Jos6 dos Compos and S~o Paulo. The second group is floristically less homogeneous and includes forests of the central and western parts of the state, usually at lower altitudes (500-700 m) and subject to hotter climatic conditions (Cwa).

-(Phytosociological study on deciduous forest remnants near Corumbá, Mato Grosso do Sul State, Brazil). A survey was made on four deciduous forest remnants in the town of Corumbá, State of Mato Grosso do , aiming to verify the floristic and structure variation of deciduous forest remnants in different relief and types of soils. The four remnants were sampled through the point quarter method. Three areas were sampled through 20 points and the fourth area was sampled through 50 points. All trees with circumference at breast height ≥ 9 cm were sampled. In the alluvial deciduous forest, 32 species were sampled, Attalea phalerata Mart. ex Spreng. (Arecaceae) and Aspidosperma australe Müll. Arg. (Apocynaceae) having the highest importance value indexes. In two areas of lowland deciduous forest 47 and 25 species were sampled, respectively; Sebastiania discolor (Spreng.) Müll. Arg. (Euphorbiaceae) and Phyllostylon rhamnoides (J. Poiss.) Taub. (Ulmaceae) being the most important in both. In the remnant of submontane deciduous forest 24 species were sampled, Acosmium cardenasii H.S. Irwin & Arroyo (Fabaceae) outstanding as the main species. The richest family was Fabaceae with 16 species, followed by Euphorbiaceae with six species, and Apocynaceae, Rubiaceae and Sapindaceae with five species each. Both areas of lowland forests showed to be very similar in floristic composition as well as in structure. The alluvial forest presented the most distinct structure and floristic when compared to the other areas. These remnants of deciduous forests have peculiar structure and floristic composition, containing species of the Chaco and Caatinga Provinces that require extensive botanical and ecological studies. A família mais rica nas áreas estudadas foi Fabaceae, com 16 espécies, seguida por Euphorbiaceae, com seis espécies, e por Apocynaceae, Rubiaceae e Sapindaceae, com três espécies cada. As duas áreas de florestas de terras baixas mostraram-se muito similares, tanto na composição florística, como na estrutura. A floresta aluvial apresentou composição florística e estrutura mais distintas das demais áreas. Estes remanescentes de florestas estacionais deciduais apresentaram estrutura e composição florística peculiares, com elementos do chaco e da caatinga, merecendo a intensificação de estudos botânicos e ecológicos.Palavras-chave -Centro-Oeste brasileiro, composição florística, floresta decídua, solo calcário

-(Distribution and abundance of tree species of savanna woodland in Pantanal wetlands, Mato Grosso do Sul State, Brazil). The woodland savannas occupy non-flooding areas in the Pantanal wetlands and are an important resource for regional economy. Even though, wood from woodland savannas are cut and used for fences, pens, and sheds in the farm, there are not much information from woodland savannas regarding sustainable uses and conservation. This study investigated the abundance, the distribution of species and correlations with soil fertility in six areas of woodland savanna ("cerradão") in Southern Pantanal wetlands. The survey was accomplished by means of 30 point-centred quarters in each area, totalling 120 trees sampled with the circumference at breast height (CBH) ≥ 15 cm. The association between floristic composition, abundance of species and soil fertility were determined by the principal components analysis (PCA). Savanna forests are very heterogeneous, presenting different levels of soil fertility as well as vegetation structure and composition. Two of them were clustered according to soil fertility and vegetation structure, they both presented large stands of the tree Qualea grandiflora Mart., species that seems to prefer soil with larger phosphorous quantity. Two other areas of savanna forests showed similar floristic composition, despite being in areas where the soil presented different levels of fertility, pointing out the human disturbance.Key words -phosphorus, principal components analysis, savanna, soil RESUMO -(Distribuição e abundância de espécies arbóreas em cerradões no Pantanal, Estado do Mato Grosso do Sul, Brasil). Os cerradões no Pantanal ocorrem em áreas não inundáveis da planície e são importantes para a economia regional. Das áreas de cerradão são retiradas madeiras para construção de cercas, currais e galpões. Apesar da grande importância dos recursos vegetais do cerradão, existem poucas informações para embasar sua conservação e uso sustentável. Este trabalho teve como objetivos estudar a abundância, a distribuição das espécies arbóreas e correlações com a fertilidade do solo em áreas de cerradão (savana florestada) do Pantanal Sul Mato-grossense. Foram estudadas seis áreas de cerradão na sub-região da Nhecolândia, por meio de 30 pontos quadrantes, totalizando 120 árvores amostradas, com circunferência a altura do peito (CAP) ≥ 15 cm, em cada área. As comparações florísticas, de abundância das espécies e de fertilidade do solo, foram efetuadas por análises de componentes principais (PCA). As áreas mostraram-se heterogêneas, apresentando diferentes níveis de fertilidade do solo, estrutura e composição da vegetação. Dois cerradões foram agrupados em termos de fertilidade do solo e de estrutura da vegetação, apresentando muitas árvores de Qualea grandiflora Mart., espécie que ocorreu associada a solos com maiores teores de fósforo. Outros dois cerradões apresentaram composição florística mais semelhante que os demais, apesar de ocorrerem em solos com diferentes níveis de ferti...
