The Pantanal wetland harbors a rich flora with uncharted pharmacological potential. This study evaluated 20 Brazilian Pantanal plants against Candida albicans, C. parapsilosis, C. tropicalis, and C. krusei. Fungal susceptibility was determined by agar diffusion and broth microdilution; active compounds were identified by bioautography and HPLC-DAD-...

Copernicia alba (Morong ex Morong & Britton) is a palm tree native to tropical and subtropical climates, commonly named “carandá”, that often forms monodominant populations in the Pantanal wetland in Brazil. Currently, the knowledge of the seed germination behavior of C. alba is still limited, as well as seed viability in ex-situ conservation under...
Chapter
The Brazilian Pantanal is formed by a mosaic of plant physiognomies both in the humid floodplain and flood-free areas. Several native species are part of the culture of the local human populations and are strategic for their food and nutrition security and food sovereignty. We aim to present nutritional value of the main wild food plant species fro...
Article
Flood and fire act as ecological filters which can interact to shape forest structure and species composition. Our objective was to investigate how the interaction between fire and flood influences richness, abundance, basal area and species composition of the tree community and the monodominant belts of Attalea phalerata Mart. in forest islets of...

Smoke from wildfires worsened the situation of isolated, as well as urban communities, already under an increasing toll of COVID-19. Here we review the impacts and the possible causes of the 2020 mega-fires and recommend improvements for public policies and fire management in this wetland. We calculated the amount of area burnt annually since 2003...

South America’s Pantanal is recognized as one of the largest wetlands in the world and a UNESCO World Heritage Site for its ecological significance (high biodiversity). The region experiences both seasonal wet/dry periods and pluriannual cycles of wet and dry years. Vegetation changes throughout the year as well as over the long-term with fires and...

Questions Inundation is an important feature linked to monodominance in tropical wetlands. The occurrence of neighbouring monodominant species indicates that soil can also have an important role. This study aimed to determine if variations in densities of three neighbouring monodominant species, Byrsonima cydoniifolia, Copernicia alba and Tabebuia...
Article
Contrasting responses of seed germination to fire have been reported in different vegetation worldwide. In Brazil, the Pantanal harbors one of the world's most extensive floodplains, marked by flooding periods alternating with a dry fire-prone season. The present study aimed to understand the role of fire on regeneration from seed in the Pantanal w...
Article
Environmental filters affect species diversity. Understanding their influence on plant communities is one of the main challenges of ecology in the search for solutions to the management and conservation of floodable savannas. To shed more light on this challenge, the present work asked if the interactions between flood and fire influence the richne...
Chapter
Monodominance is defined as a phenomenon whereby a single species can cover most of the terrain in comparison with other species. In tropical environments, monodominance can be considered as an odd phenomenon because of the high species diversity that is normally found in a single hectare. In the tropics, this phenomenon is more common in floodable...

Trans­plan­ta­tion of nat­u­rally re­gen­er­at­ing seedlings (here­after wildlings) has great po­ten­tial as a restora­tion tool as it in­volves the use of ac­cli­ma­tized in­di­vid­u­als and preser­va­tion of lo­cal and en­demic geno­types. When suc­cess­fully used, this tech­nique has the added ben­e­fits of in­creas­ing struc­tural and com­po­si...

Climatic factors can influence the establishment and growth of wood species, but little is known about the effect of these factors on monodominant communities in wetlands. Therefore, we asked how climatic factors, such as ENSO (El Niño-Southern Oscillation), precipitation and flooding, influence growth and establishment of the dominant species Eryt...

Inundation and fire can affect the structure of riparian vegetation in wetlands. Our aim was to verify if there are differences in richness, abundance, basal area, composition and topographic preference of woody species in riparian forests related to the fire history, flooding duration, or the interaction between both. The study was conducted in th...
