Significance Amazonia is not only the world’s most diverse rainforest but also region in tropical America that has contributed to its total biodiversity. We show this by estimating and comparing evolutionary history of a large number animal plant species. find there been extensive interchange lineages among different regions biomes, over course tens millions years. stands out as primary source diversity, which can be mainly explained amount time Amazonian have occupied region. The...
Estimates of extinction risk for Amazonian plant and animal species are rare not often incorporated into land-use policy conservation planning. We overlay spatial distribution models with historical projected deforestation to show that at least 36% up 57% all tree likely qualify as globally threatened under International Union Conservation Nature (IUCN) Red List criteria. If confirmed, these results would increase the number on Earth by 22%. trends observed in Amazonia apply trees throughout...
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
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...
Papaya (Carica papaya) is a crop of great economic importance, and the species was among first plants to have its genome sequenced. However, there has never been complete species-level phylogeny for Caricaceae, crop's closest relatives are therefore unknown. We investigated evolution Caricaceae based on sequences from all genera, monospecific Carica, African Cylicomorpha with two species, South American Jacaratia Vasconcellea together c. 28 Mexican/Guatemalan Jarilla Horovitzia four species....
Species occurrence records provide the basis for many biodiversity studies. They derive from georeferenced specimens deposited in natural history collections and visual observations, such as those obtained through various mobile applications. Given rapid increase availability of data, control quality accuracy constitutes a particular concern. Automatic filtering is scalable reproducible means to identify potentially problematic tailor datasets public databases Global Biodiversity Information...
Tree diversity and composition in Amazonia are known to be strongly determined by the water supplied precipitation. Nevertheless, within same climatic regime, availability is modulated local topography soil characteristics (hereafter referred as hydrological conditions), varying from saturated poorly drained well‐drained potentially dry areas. While these conditions may expected influence species distribution, impacts of on tree remain understood at whole Amazon basin scale. Using a dataset...
The invasion of non-native species into rare habitats with unique plant communities represents a significant challenge to biodiversity management and conservation. Inselbergs, granitic and/or gneissic rocky outcrops, typically exhibit distinct abiotic conditions compared the surrounding matrix host diverse array highly specialized species. However, these ecosystems are increasingly threatened by colonization plants, jeopardizing their biodiversity. This study aimed to: (1) compile first...
Abstract The literature on tropical rain forest plant‐community relationships with environmental factors usually does not recognize that the relative importance of recorded in each study might be due to their amplitude variation within sites. Geographic scale, however, is recognized as an important modulator this importance. To disentangle effects scale and amplitude, ferns trees two landscapes same size (each 25 km 2 ) different soil‐fertility amplitudes but similar soil‐texture range were...
Caricaceae include six genera and 34 species, among them papaya, a model species in plant sex chromosome research. The family was held to have conserved karyotype with 2n = 18 chromosomes, an assumption based on few counts. We examined the karyotypes genome size of from all test for possible cytogenetic variation.We used fluorescent situ hybridization using standard telomere, 5S, 45S rDNA probes. New published data were combined phylogeny, molecular clock dating, C values (available ∼50%...
Abstract Here, we examine the influence of spatial distribution open white‐sand campina (WSC) in Amazon on species richness and beta diversity their vascular plants. It is well known that tends to increase with geographical distance, but habitat insularity floristic composition endemism still unclear. We surveyed WSC central southwestern Amazon, generating lists occurrences by rapid‐inventory techniques evaluate island area connectivity alpha among five landscapes Basin. Effects were...
The database of the Brazilian Program for Biodiversity Research (PPBio; GIVD ID SA-BR-001) includes data on environment and biological groups such as plants.It is organized by site, which usually a grid with 10 to 72 uniformly-distributed plots, has already surveyed 1,638 relevés across different ecosystems.The sampling design based RAPELD system allow integration from diverse taxa ecosystem processes.RAPELD spatially-explicit scheme monitor biodiversity in long-term ecological research...
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...
Stingless bees are major flower visitors in the tropics, but their foraging preferences and behavior still poorly understood. Studying stingless bee interactions with angiosperms is methodologically challenging due to high tropical plant diversity inaccessibility of upper canopy flowers forested habitats. Pollen DNA metabarcoding offers an opportunity assessing floral visitation efficiently was applied here understand resources spectra behavior. We analyzed pollen honey from nests three...
Cacti are characteristic elements of the Neotropical flora and major interest for biogeographic, evolutionary, ecological studies. We tested global biogeographic boundaries Cactaceae using specimen-based occurrences, coupled with data from visual observations, as a means to tackle known collection biases in family.Species richness record density were assessed preserved specimens human bioregional scheme tailored was produced interactive web application Infomap Bioregions, based on 261,272...
The need for taxonomists to take full advantage of biodiversity informatics has been clear at least 10 years. Significant progress made in providing access taxonomic resources online, including images specimens (especially types), original species descriptions, and georeferenced collection data. However, spite persuasive calls e-monography, there are few, if any, completed project, even though monographic research is the only mechanism reducing synonymous names, which estimated comprise 50%...
