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
