    Abstract This paper describes the Jodï horticultural system, including belief, knowledge and practice aspects. The horticulturalpractices of the Jodï were previously characterized as ‘incipient cultivation’ but such practices were poorly described anddocumented. The antiquity of cultivation among this group is suggested by the prominence and significance of horticulturalproducts and techniques in myth and ritual. Our field observations uncovered a fairly sophisticated system of plantmanagement in swiddens, house gardens, trail gardens and natural forest gaps. An inventory of 67 cultivated plant specieswas documented, of which 36 are utilized for food, 20 for magical or medicinal purposes, and 11 for technology. The Jodïprolong the productive phase of their gardens for five years or more through successive planting-harvesting-replantingoperations. Jodï swiddens display an elaborate polycultivated appearance and they possess at least five principal crops:plantain/banana, maize, yams, sweet potato, and sweet manioc. Another distinctive feature is the extensive use of naturalgaps in the forest canopy as cultivation zones. The results of this study suggest that while Jodï horticultural practice iswell integrated with a nomadic, foraging-dependent lifestyle, nevertheless this system does not deserve to be labeled as‘incipient’ and instead is more integral than was recognized previously.

    Abstract This paper reflects on practical and conceptual lessons acquired as a result of our participation in a project of self-demarcation of indigenous lands in Venezuela. The project was based on a collaboration between academics from the Venezuelan Institute for Scientific Research (IVIC) and local communities of the Jodï and Eñepa ethnic groups. The goal was to prepare maps of community lands and compile all of the documentation required to petition the Venezuelan State for the land title. The first point proves the importance of alliances among local communities and external actors (such as academy-trained researchers) in order to navigate the complicated route of ethno-cartographic documentation and bureaucratic motions that leads from the theoretical recognition of territorial rights to the real and effective tenure over the land. Such collaborations imply the integration of complementary capabilities but also the mutual understanding of dissimilar perceptions and interests. In the second place, we analyze the ambiguity of the State in regards to Indian land rights recognition throughout the Bolivarian constitutional period, as reflected in various contradictions between written laws and legal practices, the separate actions and attitudes of different government agents at regional and national levels, the inconsistencies in the institutional authorities and application of norms established to promote the demarcation process, the legal lacunae or recurrent changes in the rules regarding the petition of land rights recognition, among other aspects that have impeded reaching the final goal of indigenous land demarcations: obtaining legal title or ownership rights over their lands. Third, the multiple realities of the map are evidenced by spatial-temporal polysemy, which have forced us to recognize the different ways of perceiving and experiencing space and time among non-western peoples, for example internalized in daily life yet externalized in symbolic representations at the same time. Lastly, we explore how ...

    Abstract Abstract Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and richness. Using only location, stratified by forest type, as predictor, our spatial model, to the best of our knowledge, provides the most accurate map of tree diversity in Amazonia to date, explaining approximately 70% of the tree diversity and species-richness. Large soil-forest combinations determine a significant percentage of the variation in tree species-richness and tree alpha-diversity in Amazonian forest-plots. We suggest that the size and fragmentation of these systems drive their large-scale diversity patterns and hence local diversity. A model not using location but cumulative water deficit, tree density, and temperature seasonality explains 47% of the tree species-richness in the terra-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 variation may be local. The Guyana Shield area has consistently negative residuals, showing that this area has lower tree species-richness than expected by our models. We provide extensive plot meta-data, including tree density, tree alpha-diversity and tree species-richness results and gridded maps at 0.1-degree resolution.

    Abstract Abstract Amazonian forests are extraordinarily diverse, but the estimated species richness is very much debated. Here, we apply an ensemble of parametric estimators and a novel technique that includes conspecific spatial aggregation to an extended database of forest plots with up-to-date taxonomy. We show that the species abundance distribution of Amazonia is best approximated by a logseries with aggregated individuals, where aggregation increases with rarity. By averaging several methods to estimate total richness, we confirm that over 15,000 tree species are expected to occur in Amazonia. We also show that using ten times the number of plots would result in an increase to just ~50% of those 15,000 estimated species. To get a more complete sample of all tree species, rigorous field campaigns may be needed but the number of trees in Amazonia will remain an estimate for years to come.

    Abstract Abstract Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such “monodominant” forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence of monodominance in a massive, basin-wide database of forest-inventory plots from the Amazon Tree Diversity Network (ATDN). Utilizing a simple defining metric of at least half of the trees ≥ 10 cm diameter belonging to one species, we found only a few occurrences of monodominance in Amazonia, and the phenomenon was not significantly linked to previously hypothesized life history traits such wood density, seed mass, ectomycorrhizal associations, or Rhizobium nodulation. In our analysis, coppicing (the formation of sprouts at the base of the tree or on roots) was the only trait significantly linked to monodominance. While at specific locales coppicing or ectomycorrhizal associations may confer a considerable advantage to a tree species and lead to its monodominance, very few species have these traits. Mining of the ATDN dataset suggests that monodominance is quite rare in Amazonia, and may be linked primarily to edaphic factors.

    Abstract Abstract Species distribution models (SDMs) are widely used in ecology and conservation. Presence-only SDMs such as MaxEnt frequently use natural history collections (NHCs) as occurrence data, given their huge numbers and accessibility. NHCs are often spatially biased which may generate inaccuracies in SDMs. Here, we test how the distribution of NHCs and MaxEnt predictions relates to a spatial abundance model, based on a large plot dataset for Amazonian tree species, using inverse distance weighting (IDW). We also propose a new pipeline to deal with inconsistencies in NHCs and to limit the area of occupancy of the species. We found a significant but weak positive relationship between the distribution of NHCs and IDW for 66% of the species. The relationship between SDMs and IDW was also significant but weakly positive for 95% of the species, and sensitivity for both analyses was high. Furthermore, the pipeline removed half of the NHCs records. Presence-only SDM applications should consider this limitation, especially for large biodiversity assessments projects, when they are automatically generated without subsequent checking. Our pipeline provides a conservative estimate of a species’ area of occupancy, within an area slightly larger than its extent of occurrence, compatible to e.g. IUCN red list assessments.

    Abstract Seeing the Trees in the Forest Despite botanical exploration over two centuries, knowledge of the species composition and quantitative distribution of the trees of the Amazonian forest has remained decidedly patchy. Ter Steege et al. (1243092) report the results from a network of 1170 tree plots arrayed across the Amazon Basin and Guiana Shield, in which the species of all trees with stem diameter >10 centimeters were identified. The tree flora comprised a total of about 16,000 species. However, just 227 very common Amazonian species accounted for half of the trees in the Amazon—the world's most diverse forest.

    Abstract Resumen En este artículo se presenta una descripción de las formas de manejo agrícola entre los Pumé desde una perspectiva etnoecológica. Los Pumé son un pueblo indígena que habita en la ecorregión de los Llanos (Venezuela). Aunque han sido identificados por algunos etnógrafos como un grupo de cazadores-recolectores, desde hace tiempo se ha señalado que poseen economías mixtas. Basados o no en las descripciones etnográficas, los agentes del Estado también han hecho representaciones de los Pumé como un grupo que carece de conocimientos agrícolas. En este sentido, el enfoque etnoecológico constituye la posibilidad de considerar aspectos cognitivos, perceptuales, cosmológicos y prácticos de la agricultura de este pueblo indígena. A partir de un estudio etnográfico, se describen siete formas de manejo agrícola que difieren en características como nivel de manejo, extensión, organización social del trabajo y propiedad de la cosecha. Por último, se profundiza en la descripción de los aspectos etnoecológicos de la agricultura de tala y quema de este grupo.

    Abstract This paper describes the Jodï horticultural system, including belief, knowledge and practice aspects. The horticultural practices of the Jodï were previously characterized as 'incipient cultivation' but such practices were poorly described and documented. The antiquity of cultivation among this group is suggested by the prominence and significance of horticultural products and techniques in myth and ritual. Our field observations uncovered a fairly sophisticated system of plant management in swiddens, house gardens, trail gardens and natural forest gaps. An inventory of 67 cultivated plant species was documented, of which 36 are utilized for food, 20 for magical or medicinal purposes, and 11 for technology. The Jodï prolong the productive phase of their gardens for five years or more through successive planting-harvesting-replanting operations. Jodï swiddens display an elaborate polycultivated appearance and they possess at least five principal crops: plantain/banana, maize, yams, sweet potato, and sweet manioc. Another distinctive feature is the extensive use of natural gaps in the forest canopy as cultivation zones. The results of this study suggest that while Jodï horticultural practice is well integrated with a nomadic, foraging-dependent lifestyle, nevertheless this system does not deserve to be labeled as 'incipient' and instead is more integral than was recognized previously.
