Aim Biodiversity information is the focus of major initiatives aimed at assembling large-scale primary-data documentation ('digital accessible knowledge') of the distribution of life on Earth. Recent efforts within Brazil have assembled a massive amount of such documentation for Brazilian plants, which we analyse in this study. Our aim is to identify areas representing gaps in current knowledge; these gaps can guide future botanical exploration and discovery in Brazil. Location Brazil.Methods We assessed angiosperm inventories across Brazil at diverse spatial scales using statistics that summarize inventory completeness. In particular, we assess the completeness of geographical knowledge of Brazilian floras as measured in terms of geographical distance and climatic difference from welldocumented sites.Results Spatial knowledge of Brazilian angiosperms is very unevenly distributed: well-known sites are concentrated in eastern and southern regions, whereas the remainder of the country remains poorly documented. Worse still, in many regions, areas lacking detailed botanical documentation coincide with areas of intense habitat destruction, such that many such sites will never be documented scientifically.Main conclusions This study illustrates how biodiversity survey and inventory efforts can be guided by existing knowledge. That is, to the extent that existing biodiversity knowledge is made digital and openly available, and to the extent that information is sufficiently comprehensive and informative, spatial summaries of completeness such as that presented here offer clear and strategic directions for maximizing the yield of new knowledge from any de novo field efforts.

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.

Abstract. In November 2015, a large mine-tailing dam owned by Samarco Corporation collapsed in Brazil, generating a massive wave of toxic mud that spread down the Doce River, killing 20 people and affecting biodiversity across hundreds of kilometers of river, riparian lands, and Atlantic coast. Besides the disaster's serious human and socioeconomic tolls, we estimate the regional loss of environmental services to be ~US$521 million per year. Although our estimate is conservative, it is still six times higher than the fine imposed on Samarco by Brazilian environmental authorities. To reduce such disparities between estimated damages and levied fines, we advocate for an environmental bond policy that considers potential risks and environmental services that could possibly be impacted by irresponsible mining activity. Environmental bonds and insurance are commonly used policy instruments in many countries, but there are no clear environmental bond policies in Brazil. Environmental bonds are likely to be more effective at securing environmental restitution than post-disaster fines, which generally are inadequate and often unpaid. We estimate that at least 126 mining dams in Brazil are vulnerable to failure in the forthcoming years. Any such event could have severe socialenvironmental consequences, underscoring the need for effective disaster-management strategies for large-scale mining operations.

Frugivores and pollinators are two functional groups of animals that help ensure gene flow of plants among sites in landscapes under restoration and to accelerate restoration processes. Resource availability is postulated to be a key factor to structure animal communities using restoration sites, but it remains poorly studied. We expected that diverse forests with many plant growth forms that have less-seasonal phenological patterns will provide more resources for animals than forests with fewer plant growth forms and strongly seasonal phenological patterns. We studied forests where original plantings included high tree species diversity. We studied resource provision (richness and abundance of flowers and fruits) of all plant growth forms, in three restoration sites of different ages compared to a reference forest, investigating whether plant phenology changes with restoration process. We recorded phenological data for reproductive plant individuals (351 species) with monthly sampling over 2 years, and found that flower and fruit production have been recovered after one decade of restoration, indicating resource provision for fauna. Our data suggest that a wide range of plant growth forms provides resource complementarities to those of planted tree species. Different flower phenologies between trees and non-trees seem to be more evident in a forest with high non-tree species diversity. We recommend examples of ideal species for planting, both at the time of initial planting and post-planting during enrichment. These management actions can minimize shortage and periods of resource scarcity for frugivorous and nectarivorous fauna, increasing probability of restoring ecological processes and sustainability in restoration sites.Abstract in Portuguese is available in the online version of this article.
