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.

We present the floristic composition and reproductive phenological data for a remnant of Arborized Stepic Savanna, vegetation type of humid Chaco, Porto Murtinho, Mato Grosso do Sul State, Brazil. We recorded 87 species of 31 families; Leguminosae presented the highest richness (14 species), followed by Malvaceae (9), Cactaceae (7) and Asteraceae (7). The herbaceous layer is relevant in the seasonal studied community (53.5% of the species) and there is predominance of non-perennial species (hemicryptophytes and therophytes), which demonstrate the importance of underground structures or seed banks in the vegetation. The community has continual flowering and fruiting with highest intensity in the rainy season, the most favorable period for plant growth and reproduction. The predominance of autochoric species in relation to anemochoric and zoochoric ones suggests partial independence of seed/fruit dispersal agents. Zoochorous species predominated in the rainy season, whereas anemochorous and autochorous species were more representative in the dry season.

RESUMO O Chaco brasileiro se situa na borda oeste do estado de Mato Grosso do Sul, ocupando cerca de 7% da sub-região do Pantanal do Nabileque. O objetivo deste estudo foi efetuar o levantamento florístico de espécies arbóreas em remanescentes de Chaco no município de Porto Murtinho, investigando os tipos de frutos, a ocorrência e a distribuição das síndromes de dispersão. Foram amostrados 24 famílias, 40 gêneros e 49 espécies. As famílias mais representativas em número de espécies foram Leguminosae (21 espécies), seguida por Bignoniaceae (três espécies), Anacardiaceae, Myrtaceae e Sapindaceae (com duas espécies cada). Os tipos de frutos predominantes foram cápsulas, legume s.s. e drupóides. Quanto às síndromes de dispersão, a zoocoria (52%) foi a predominante, seguida pela anemocoria (26%) e a autocoria (22%). O estrato arbóreo mostrou-se bastante dependente da fauna para a dispersão, o que pode resultar em lacunas de distribuição caso seus dispersores se tornem raros ou extintos.

RESUMO (Estudo taxonômico de Stylosanthes (Leguminosae - Papilionoideae - Dalbergieae) em Mato Grosso do Sul, Brasil) Stylosanthes é um gênero pantropical constituído por 50 espécies, sendo a metade destas registradas no Brasil. Neste estudo é apresentado o levantamento das espécies de Stylosanthes ocorrentes em Mato Grosso do Sul, por meio de análises de material depositado em herbários nacionais e de coletas efetuadas no estado. Stylosanthes está representado em Mato Grosso do Sul por 17 espécies, distribuídas em duas seções. Stylosanthes seção Styposanthes está representada por cinco espécies: S. bracteata, S. capitata, S. hamata, S. macrocephala e S. scabra e Stylosanthes seção Stylosanthes por 12 espécies: S. acuminata, S. gracilis, S. grandifolia, S. guianensis, S. hippocampoides, S. humilis, S. linearifolia, S. longiseta, S. maracajuensis, S. montevidensis, S. nunoi e S. viscosa. São ocorrências inéditas para o estado: S. capitata, S. hamata, S. hippocampoides, S. humilis, S. linearifolia, S. macrocephala, S. montevidensis e S. nunoi. Em Mato Grosso do Sul verifica-se que as espécies de Stylosanthes podem ocorrer no cerrado, cerradão, campo sujo e chaco.

Herbaria represent irreplaceable repositories of biodiversity and are used to answer questions about conservation, ecology, systematics, and other sciences. In this sense, we characterize the infrastructure, human resources, and idiosyncrasies of Brazilian herbaria. To achieve this goal, curators were sent a structured and standardized questionnaire to gather information about herbaria. The Brazilian Herbaria Network listed 216 active herbaria in the year 2018, of which 139 answered the questionnaire. These herbaria hold 6,741,469 samples in their collections and more than 39,000 type samples. Most herbaria are in federal universities (40.28 %). Only 24 % of the curators considered that their herbarium is valued by their institutions and 52 % indicated inadequate storage areas. Only nine collections have smoke sensors. Our analysis showed that if an herbarium has an institutional policy the curator is 78 % more likely to consider its herbarium valued. Therefore, it is important for all herbaria to institute their policy. These numbers reflect the difficulty in maintaining herbaria, in many cases cared for only by its curator without institutional recognition and support. Despite recent losses in Brazilian natural history collections, herbaria are still threatened by a lack of basic infrastructure.

Questions:(1) Do woody species flourish and fructify according to environmental seasonality? (2) Is there a positive correlation with dry/rainy season? (3) Are the flowering and fruiting of woody species positively correlated with rainfall, temperature and photoperiod? (4) Do anemochorous, autochorous and zoochorous species fructify according to environmental seasonality, i.e. dry or rainy season?Location: Thorn forest, southern Midwest Brazil. Methods: Qualitative data collection included the presence or absence of flowers and/or fruits of each species, independently of the development phase of their reproductive organs. A Rayleigh test was used to determine if flowering and fructification were seasonal throughout the year and to detect possible significant seasonal patterns. Spearman's rank correlation and Bonferroni correction were used to determine possible correlations between phenological events and rainfall, temperature and photoperiod.Results: Flowering and fruiting of the woody community showed a low degree of seasonality. No significant correlations were found between flowering and fructification and the climatic variables studied: temperature, photoperiod and rainfall. Approximately 60% of the zoochorous species bore fruit during the rainy season, but with a low degree of seasonality. The fruiting of anemochorous species presented two opposite points of higher frequency, corresponding to the transition period between rainfall and drought and the rainy season. No seasonality was found. Autochorous species showed no pattern of seasonal fruiting. Conclusions:The data on flowering and fruiting in the community studied are unexpected and contrast with studies performed in seasonal environments. Seed dispersal syndromes showed no significant seasonal events. These results differ from those usually found in markedly seasonal environments. The Brazilian Chaco can be considered an arid environment in which abiotic syndromes prevail in a manner similar to that seen in tropical dry forests.
