    Abstract: This volume is a monograph of the genus Diplusodon (Lythraceae), written by the world authority on this plant group. Diplusodon is a monophyletic genus of shrubs and subshrubs, with showy, 6-merous, actinomorphic flowers, and floral tubes on which the sepals alternate with conspicuous epicalyx segments. The capsular fruit contains winged seeds and, uniquely for the family, is divided by a bipartite placenta with two semi-lunate septa. Diplusodon is the second largest genus in the Lythraceae and occurs mostly in the Cerrado Biome, the floristically diverse savannah that covers more than two million km2 of the Central Brazilian Plateau, extending west into Bolivia, south to Paraguay and east to the Caatinga. A total of 104 species and eight varieties are recognized in the genus, for which 46 lectotypes, one neotype, one new status and one new combination are designated, nine new species are described, and 15 taxa are placed in synonymy. New information on floral and vegetative morphology, pollen, cytology, chemistry, floral biology, and habitat are provided for the genus. In addition, keys to the species are accompanied by descriptions, illustrations, distribution maps, and assignment of conservation status.

    Abstract: This book reviews empirical and theoretical research on sustainable development in the context of leisure management for communities. Although leading research centers are pursuing interdisciplinary research on leisure in the context of sustainable development, there are still few papers that holistically address the current challenges in this area. In addition, demographic changes have made the promotion of a healthy lifestyle essential. Doing so requires responsible behavior on the part of various stakeholders in this market. This book fills an important gap in the literature and gathers contributions from an interdisciplinary and international team of authors, whose fields of expertise include human geography, management, intersections of sustainability and leisure, behavioral psychology and tourism.

    Geomorphology of Brazil: Complexity, Interscale and Landscape : XIII SINAGEO (National Symposium of Geomorphology) (2022)
    Cham :Springer International Publishing :
    Details
    Keywords: Geomorphology. ; Sedimentology. ; Geomorphology. ; Sedimentology.
    Description / Table of Contents: Geomorphological Units Of Brazil: A Review In The Context Of Brazilian Spatial Planning -- Geomorphological Structuring And Tectonic Control In The Southeastern Brazilian Stepped Reliefs: Relation With The Evolution Of Crystalline Scarps -- Pedogeomorphological Compartments Of Coastal Tablelands In Amapá, Eastern Amazon -- Geomorphological Evolution Of River Forms In Humid And Semi-Arid Tropical Environments -- Hydrogeomorphology Of Brazilian Springs: Between Diversity And Lack Of Knowledge.
    Abstract: This book presents the most relevant articles selected from the annals of the symposium. In the last few years, Brazilian Geomorphology has experienced a series of epistemological and methodological innovations expressed by the incorporation of the complexity paradigm, by the progressive break with the climate paradigm, by the emergency role of new theories, and by the advances in methodological fields favored by the adherence to geochronological techniques and in function of the increasingly widespread use of geotechnologies. Furthermore, the Anthropocene/Technogene emerge claims to be more than only a temporal cuts, but as conceptions of a science engaged with social and environmental issues. The National Symposium of Geomorphology, in the maturity of its 13th edition, constitutes a portrait and an important sample of Brazilian geomorphological production, aggregating works carried out in the most diverse types of landscapes of Brazil. The book provides an overview of the current scientific production of Brazilian Geomorphology, highlighting the diversity of landscapes and geoheritage in Brazil, the complexity of the morphogenetic and morphodynamic processes responsible for shaping its surface, and the various abundant methodologies used in geomorphological studies in tropical areas.

    Mapping density, diversity and species-richness of the Amazon tree flora (2023)
    In:  Communications Biology vol. 6 no. 1130, pp. 1-14
    Details
    Publication Date: 2024-01-31
    Description: Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we \nmapped tree species-diversity and tree species-richness at 0.1-degree resolution, and \ninvestigated drivers for diversity and richness. Using only location, stratified by forest type, as \npredictor, our spatial model, to the best of our knowledge, provides the most accurate map of \ntree diversity in Amazonia to date, explaining approximately 70% of the tree diversity and \nspecies-richness. Large soil-forest combinations determine a significant percentage of the \nvariation in tree species-richness and tree alpha-diversity in Amazonian forest-plots. We \nsuggest that the size and fragmentation of these systems drive their large-scale diversity \npatterns and hence local diversity. A model not using location but cumulative water deficit, \ntree density, and temperature seasonality explains 47% of the tree species-richness in the \nterra-firme forest in Amazonia. Over large areas across Amazonia, residuals of this relationship are small and poorly spatially structured, suggesting that much of the residual \nvariation may be local. The Guyana Shield area has consistently negative residuals, showing \nthat this area has lower tree species-richness than expected by our models. We provide \nextensive plot meta-data, including tree density, tree alpha-diversity and tree speciesrichness results and gridded maps at 0.1-degree resolution.

    One sixth of Amazonian tree diversity is dependent on river floodplains (2024)
    In:  Nature Ecology & Evolution vol. 2024
    Details
    Publication Date: 2024-04-05
    Description: Amazonia’s floodplain system is the largest and most biodiverse on Earth. Although forests are crucial to the ecological integrity of floodplains, our understanding of their species composition and how this may differ from surrounding forest types is still far too limited, particularly as changing inundation regimes begin to reshape floodplain tree communities and the critical ecosystem functions they underpin. Here we address this gap by taking a spatially explicit look at Amazonia-wide patterns of tree-species turnover and ecological specialization of the region’s floodplain forests. We show that the majority of Amazonian tree species can inhabit floodplains, and about a sixth of Amazonian tree diversity is ecologically specialized on floodplains. The degree of specialization in floodplain communities is driven by regional flood patterns, with the most compositionally differentiated floodplain forests located centrally within the fluvial network and contingent on the most extraordinary flood magnitudes regionally. Our results provide a spatially explicit view of ecological specialization of floodplain forest communities and expose the need for whole-basin hydrological integrity to protect the Amazon’s tree diversity and its function.

    Consistent patterns of common species across tropical tree communities (2024)
    In:  Nature vol. 625 no. 7996, pp. 728-734
    Details
    Publication Date: 2024-04-13
    Description: Trees structure the Earth's most biodiverse ecosystem, tropical forests. The vast number of tree species presents a formidable challenge to understanding these forests, including their response to environmental change, as very little is known about most tropical tree species. A focus on the common species may circumvent this challenge. Here we investigate abundance patterns of common tree species using inventory data on 1,003,805 trees with trunk diameters of at least 10 cm across 1,568 locations1-6 in closed-canopy, structurally intact old-growth tropical forests in Africa, Amazonia and Southeast Asia. We estimate that 2.2%, 2.2% and 2.3% of species comprise 50% of the tropical trees in these regions, respectively. Extrapolating across all closed-canopy tropical forests, we estimate that just 1,053 species comprise half of Earth's 800 billion tropical trees with trunk diameters of at least 10 cm. Despite differing biogeographic, climatic and anthropogenic histories7, we find notably consistent patterns of common species and species abundance distributions across the continents. This suggests that fundamental mechanisms of tree community assembly may apply to all tropical forests. Resampling analyses show that the most common species are likely to belong to a manageable list of known species, enabling targeted efforts to understand their ecology. Although they do not detract from the importance of rare species, our results open new opportunities to understand the world's most diverse forests, including modelling their response to environmental change, by focusing on the common species that constitute the majority of their trees.

    Geography and ecology shape the phylogenetic composition of Amazonian tree communities (2024)
    Wiley
    In:  Journal of Biogeography vol. 2024 no. 14816
    Details
    Publication Date: 2024-03-31
    Description: Aim: Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location: Amazonia. Taxon: Angiosperms (Magnoliids; Monocots; Eudicots). Methods: Data for the abundance of 5082 tree species in 1989 plots were combined with a mega-phylogeny. We applied evolutionary ordination to assess how phylogenetic composition varies across Amazonia. We used variation partitioning and Moran's eigenvector maps (MEM) to test and quantify the separate and joint contributions of spatial and environmental variables to explain the phylogenetic composition of plots. We tested the indicator value of lineages for geographic regions and edaphic forest types and mapped associations onto the phylogeny. Results: In the terra firme and várzea forest types, the phylogenetic composition varies by geographic region, but the igapó and white-sand forest types retain a unique evolutionary signature regardless of region. Overall, we find that soil chemistry, climate and topography explain 24% of the variation in phylogenetic composition, with 79% of that variation being spatially structured (R2= 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R2= 28%). A greater number of lineages were significant indicators of geographic regions than forest types. Main Conclusion: Numerous tree lineages, including some ancient ones (〉66 Ma), show strong associations with geographic regions and edaphic forest types of Amazonia. This shows that specialization in specific edaphic environments has played a long-standing role in the evolutionary assembly of Amazonian forests. Furthermore, many lineages, even those that have dispersed across Amazonia, dominate within a specific region, likely because of phylogenetically conserved niches for environmental conditions that are prevalent within regions.
