Abstract The shortage of reliable primary taxonomic data limits the description biological taxa and understanding biodiversity patterns processes, complicating biogeographical, ecological, evolutionary studies. This deficit creates a significant impediment to research conservation planning. crisis are widely recognized, highlighting urgent need for data. Over past decade, numerous countries worldwide have devoted considerable effort Target 1 Global Strategy Plant Conservation (GSPC), which...
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 environmental change, as very little is known about species. A focus on common may circumvent this challenge. Here we investigate abundance patterns using inventory data 1,003,805 trees with trunk diameters at least 10 cm across 1,568 locations
Unlike most rivers globally, nearly all lowland Amazonian have unregulated flow, supporting seasonally flooded floodplain forests. Floodplain forests harbor a unique tree species assemblage adapted to flooding and specialized fauna, including fruit-eating fish that migrate into floodplains, favoring expansive areas. Frugivorous are forest-dependent fauna critical forest regeneration via seed dispersal support commercial artisanal fisheries. We implemented linear mixed effects models...
Abstract Species distribution models (SDMs) are widely used in ecology and conservation. Presence-only SDMs such as MaxEnt frequently use natural history collections (NHCs) occurrence data, given their huge numbers accessibility. NHCs often spatially biased which may generate inaccuracies SDMs. Here, we test how the of predictions relates to a spatial abundance model, based on large plot dataset for Amazonian tree species, using inverse distance weighting (IDW). We also propose new pipeline...
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 extended database forest plots with up-to-date taxonomy. We show abundance distribution Amazonia best approximated by logseries aggregated individuals, where increases rarity. By averaging several methods estimate total richness, confirm over 15,000 tree...
Abstract Amazonia’s floodplain system is the largest and most biodiverse on Earth. Although forests are crucial to ecological integrity of floodplains, our understanding their species composition how this may differ from surrounding forest types still far too limited, particularly as changing inundation regimes begin reshape tree communities critical ecosystem functions they underpin. Here we address gap by taking a spatially explicit look at Amazonia-wide patterns tree-species turnover...
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” from all of main tropical regions. For Amazonia, we sampled occurrence monodominance massive, basin-wide database forest-inventory plots Amazon Tree Diversity Network (ATDN). Utilizing simple defining metric at least half trees ≥ 10 cm diameter belonging to one species, found only few occurrences and phenomenon was not...
Abstract Aim Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that lineages colonized multiple edaphic environments dispersed widely across Amazonia, leading to a hypothesis, which we test, should not be strongly associated with either geographic regions or forest types. Location Amazonia. Taxon Angiosperms (Magnoliids; Monocots; Eudicots). Methods Data for the abundance of 5082 in...
Abstract A new species of Cecropia (Urticaceae) is described for Amazonas state, Brazil. Collecting and processing the vouchers followed usual procedures botanical specimens. Parallel to herbarium procedures, phylogenetic analyses were performed photographs in field obtained. The shares morphological similarities with membranacea C. concolor, which are discussed this paper. It appears as a sister group analysis strongly supported clade. An identification key all known from Central Amazon...
The large flood pulse of the Amazon basin is a principal driver environmental heterogeneity with important implications for ecosystem function and assembly natural communities. Understanding species ecological response to thus key question theories coexistence, resource management, conservation. Yet these remain largely undescribed most species, in particular trees. high tree diversity Negro River floodplain makes it an ideal system begin filling this knowledge gap. We merged historical...
The unavoidable diet change in emerging countries, projected for the coming years, will significantly increase global consumption of animal protein. It is expected that Brazilian livestock production, responsible close to 15% be prepared answer increasing demand beef. Consequently, evaluation pasture quality at regional scale important inform public policies towards a rational land use strategy directed improve productivity country. Our hypothesis MODIS images can used evaluate processes...
Abstract Aim To investigate the geographic patterns and ecological correlates in distribution of most common tree dispersal modes Amazonia (endozoochory, synzoochory, anemochory hydrochory). We examined if proportional abundance these could be explained by availability agents (disperser‐availability hypothesis) and/or resources for constructing zoochorous fruits (resource‐availability hypothesis). Time period Tree‐inventory plots established between 1934 2019. Major taxa studied Trees with a...
The consensus is that Amazonian white-sand ecosystems (campinaranas) shelter several endemic plant species. However, recent studies have shown most species are generalists, and they also occur in other Neotropical ecosystems. To investigate this issue, we analyzed the proportion of endemic/specialist a checklist trees, palms, shrubs sampled between 2014 2020 campinarana patches Uatumã Sustainable Development Reserve (USDR), central Amazon. We provide description...
Abstract In a time of rapid global change, the question what determines patterns in species abundance distribution remains priority for understanding complex dynamics ecosystems. The constrained maximization information entropy provides framework such systems by quantitative analysis important constraints via predictions using least biased probability distributions. We apply it to over two thousand hectares Amazonian tree inventories across seven forest types and thirteen functional traits,...
