The experiment was carried out at the Biological Dynamics of Forest Fragments Project (BDFFP) approximately 100 km north of Manaus. Data were collected bimonthlyfrom February 2019 to January 2020, by the dataset first author. Height measurements were made with a tape measure and DRH measurements...

Eighty-four per cent of all Amazonian arboreal plant individuals are useful to humans

Sara D. Coelho, Carolina Levis, Fabrício B. Baccaro, Fernando O. G. Figueiredo, André Pinassi Antunes, Hans Ter Steege, Marielos Peña-Claros, Juliana Schietti & Charles R. Clement
Plants have been used in Amazonian forests for millennia and some of these plants are disproportionally abundant (hyperdominant). At local scales, people generally use the most abundant plants, which may be abundant as the result of management of indigenous peoples and local communities. However, it is unknown whether plant use is also associated with abundance at larger scales. We used the population sizes of 4,454 arboreal species (trees and palms) estimated from 1946 forest plots...

Mapping Africa’s biodiversity: more of the same is just not good enough

Harith Farooq, Josué Azevedo, Amadeu Soares, Alexandre Antonelli & Søren Faurby
Species distribution data are fundamental to the understanding of biodiversity patterns and processes. Yet, such data are strongly affected by sampling biases, mostly related to site accessibility. The understanding of these biases is therefore crucial in systematics, biogeography and conservation. Here we present a novel approach for quantifying sampling effort and its impact on biodiversity knowledge, focusing on Africa. In contrast to previous studies assessing sampling completeness (percentage of species recorded in relation to predicted),...

Data from: Paleoclimatic evolution as the main driver of current genomic diversity in the widespread and polymorphic Neotropical songbird Arremon taciturnus

Nelson Buainain, Roberta Canton, Gabriela Zuquim, Hanna Tuomisto, Tomas Hrbek, Hiromitsu Sato & Camila Ribas
Several factors have been proposed as drivers of species diversification in the Neotropics, including environmental heterogeneity, the development of drainage systems and historical changes in forest distribution due to climatic oscillations. Here, we investigate which drivers contributed to the evolutionary history and current patterns of diversity of a polymorphic songbird (Arremon taciturnus) that is widely distributed in Amazonian and Atlantic forests as well as in Cerrado gallery and seasonally-dry forests. We use genomic, phenotypic and...

Drought-driven wildfire impacts on structure and dynamics in a wet Central Amazonian forest

Aline Pontes-Lopes, Camila V. J. Silva, Jos Barlow, Lorena M. Rincón, Wesley A. Campanharo, Cássio A. Nunes, Catherine T. De Almeida, Celso H. L. Silva Junior, Henrique L. G. Cassol, Ricardo Dalagnol, Scott C. Stark, Paulo M.L.A. Graça & Luiz E. O. C. Aragão
While climate and human-induced forest degradation is increasing in the Amazon, fire impacts on forest dynamics remain understudied in the wetter regions of the basin, which are susceptible to large wildfires only during extreme droughts. To address this gap, we installed burned and unburned plots immediately after a wildfire in the northern Purus-Madeira (central Amazon) during the 2015 El-Niño. We measured all individuals ≥10cm in diameter at breast height, and conducted recensuses to track the...

Community composition of tree and palm species in a forest with bamboo in southwestern Amazonia

Leonardo Ziccardi & Philip Fearnside
A forest inventory was conducted in August 2016 in the municipality of Rio Branco, Acre, Brazil. This data was used in "Community composition of tree and palm species following disturbance in a forest with bamboo in southwestern Amazonia, Brazil" (Ziccardi et al., 2021). The dataset is composed by 5 variables and 1224 cases (rows). It presents data for species identified in a total of 24 plots distributed in three treatments: Fire + Logging (1); Fire...

Bat phylogenetic responses to regenerating Amazonian forests

Fábio Z. Farneda, Ricardo Rocha, Sabhrina Gita Aninta, Adrià López-Baucells, Erica M. Sampaio, Jorge M. Palmeirim, Paulo E. D. Bobrowiec, Cristian S. Dambros & Christoph F. J. Meyer
1. Throughout the tropics, regenerating secondary forests occupy vast areas previously cleared for agriculture and cattle ranching. However, despite the importance of regenerating forests in mitigating the pervasive negative consequences of forest loss and fragmentation on forest-associated biodiversity, longitudinal studies on species’ phylogenetic responses to matrix regeneration are rare. 2. We surveyed bats in continuous primary forest, primary forest fragments and in the regenerating secondary forest matrix of a whole-ecosystem Amazonian fragmentation experiment, ~15 and...

Data from: Contrasting patterns of gene flow for Amazonian snakes that actively forage and those that wait in ambush

Rafael De Fraga, Albertina P. Lima, William E. Magnusson, Miquéias Ferrão & Adam J. Stow
Knowledge of genetic structure, geographic distance and environmental heterogeneity can be used to identify environmental features and natural history traits that influence dispersal and gene flow. Foraging mode is a trait that might predict dispersal capacity in snakes, because actively foragers typically have greater movement rates than ambush predators. Here we test the hypothesis that two actively foraging snakes have higher levels of gene flow than two ambush predators. We evaluated these four co-distributed species...

Data from: Floral convergence in Oncidiinae (Cymbidieae; Orchidaceae): an expanded concept of Gomesa and a new genus Nohawilliamsia

Mark W. Chase, Norris H. Williams, Aparacida Donisete De Faria, Kurt M. Neubig, Maria Do Carmo E. Amaral & W. Mark Whitten
BACKGROUND: Floral morphology, particularly the angle of lip attachment to the column, has historically been the fundamental character used in establishing generic limits in subtribe Oncidiinae (Orchidaceae), but it has also been long recognized that reliance on this character alone has produced a highly artificial set of genera. In essence, lip/column relationships reflect syndromes associated with pollinator preferences; most genera of Oncidiinae as previously defined have consisted of a single floral type. Here, the degree...

Data from: Age‐dependent leaf physiology and consequences for crown‐scale carbon uptake during the dry season in an Amazon evergreen forest

Loren P. Albert, Jin Wu, Neill Prohaska, Plinio Barbosa De Camargo, Travis E. Huxman, Edgard S. Tribuzy, Valeriy Y. Ivanov, Rafael S. Oliveira, Sabrina Garcia, Marielle N. Smith, Raimundo Cosme Oliveira Junior, Natalia Restrepo-Coupe, Rodrigo Da Silva, Scott C. Stark, Giordane A. Martins, Deliane V. Penha & Scott R. Saleska
* Satellite and tower-based metrics of forest-scale photosynthesis generally increase with dry season progression across central Amazônia, but the underlying mechanisms lack consensus. * We conducted demographic surveys of leaf age composition, and measured age-dependence of leaf physiology in broadleaf canopy trees of abundant species at a central eastern Amazon site. Using a novel leaf-to-branch scaling approach, we used this data to independently test the much-debated hypothesis—arising from satellite and tower-based observations—that leaf phenology could...

Data from: How do seasonality, substrate, and management history influence macrofungal fruiting assemblages in a central Amazonian Forest?

Dirce Leimi Komura, Jean-Marc Moncalvo, Cristian S. Dambros, Larissa S. Bento, Maria A. Neves & Charles E. Zartman
Worldwide, fungal richness peaks in tropical forest biomes where they are the primary drivers of decomposition. Understanding how environmental and anthropogenic factors influence tropical macrofungal fruiting patterns should provide insight as to how, for example, climate change and deforestation may impact their long-term demographic stability and evolutionary potential. However, in Amazonia no studies have yet to disentangle the effects of substrate, seasonality and forest history on phenology. Here, we quantitate spatial and temporal variation in...

Data from: Subtle changes in elevation shift bat-assemblage structure in Central Amazonia

, Lucas Gabriel Do Amaral Pereirab, Valéria Da Cunha Tavaresc, William E. Magnussond, Fabricio Beggiato Baccaroe & Paulo Estefano D. Bobrowiec
The distribution patterns of animal species at local scales have been explained by direct influences of vegetation structure, topography, food distribution and availability. However, these variables can also interact and operate indirectly on the distribution of species. Here, we examined the direct and indirect effects of food availability (fruits and insects), vegetation clutter and elevation in structuring phyllostomid-bat assemblages in a continuous terra firme forest in Central Amazonia. Bats were captured in 49 plots over...

Leaf litter quality drives the feeding by invertebrate shredders in tropical streams

Guilherme Sena, José Francisco Gonçalves Júnior, Renato Martins, Neusa Hamada & Renan Rezende Rezende
Amazon and Cerrado forested streams show natural fluctuations in leaf-litter quantity along the time and space, suggesting a change on litter quality input. These natural fluctuations of leaf-litter have repercussion on the organic matter cycling and consequentlyeffects on leaf decomposition in forested streams. The effects of the quantity of leaf litter with contrasting traits on consumption by larvae of shredder insects from biomes with different organic matter dynamics have still been an understudied question. The...

Higher rates of liana regeneration after canopy fall drives species abundance patterns in central Amazonia

Elisangela Rocha, Juliana Schietti, Caian Gerolamo, Robyn Burnham & Anselmo Nogueira
In tropical rainforest, most vascular plants have some capacity to resprout, and lianas are often effective resprouters after canopy fall. However, the diversity of resprouting responses of liana species and the consequence for plant persistence is poorly understood. We hypothesized that variation in regeneration among liana species causes differences in liana species abundance in tropical rainforest through differential resprouting capacity, such that liana species with higher densities produce more resprouts after canopy falls. We applied...

Wheeler & Célio F. B. Haddad
Spiny-backed tree frogs of the genus Osteocephalus are conspicuous components of the tropical wet forests of the Amazon and the Guiana Shield. Here, we revise the phylogenetic relationships of Osteocephalus and its sister group Tepuihyla, using up to 6134 bp of DNA sequences of nine mitochondrial and one nuclear gene for 338 specimens from eight countries and 218 localities, representing 89% of the 28 currently recognized nominal species. Our phylogenetic analyses reveal (i) the paraphyly...

Heloise Gibb, Nathan J. Sanders, Robert R. Dunn, Simon Watson, Manoli Photakis, Silvia Abril, Alan N. Andersen, Elena Angulo, Inge Armbrecht, Xavier Arnan, Fabricio B. Baccaro, Tom R. Bishop, Raphael Boulay, Cristina Castracani, Israel Del Toro, Thibaut Delsinne, Mireia Diaz, David A. Donoso, Martha L. Enríquez, Tom M. Fayle, Donald H. Feener, Matthew C. Fitzpatrick, Crisanto Gómez, Donato A. Grasso, Sarah Groc … & C. Gomez
Many studies have focused on the impacts of climate change on biological assemblages, yet little is known about how climate interacts with other major anthropogenic influences on biodiversity, such as habitat disturbance. Using a unique global database of 1128 local ant assemblages, we examined whether climate mediates the effects of habitat disturbance on assemblage structure at a global scale. Species richness and evenness were associated positively with temperature, and negatively with disturbance. However, the interaction...

Quesada, Andreas Richter, Louis A. Schipper, Bryan A. Stevenson … & Bernd Zeller
Quantifying global patterns of terrestrial nitrogen (N) cycling is central to predicting future patterns of primary productivity, carbon sequestration, nutrient fluxes to aquatic systems, and climate forcing. With limited direct measures of soil N cycling at the global scale, syntheses of the 15N:14N ratio of soil organic matter across climate gradients provide key insights into understanding global patterns of N cycling. In synthesizing data from over 6000 soil samples, we show strong global relationships among...

Fine litterfall production and nutrient composition data from a fertilized site in Central Amazon, Brazil

A.C.M. Moraes, C.A. Quesada, K. Andersen, I.P. Hartley & M.P. Martins
The data consists of litterfall production in a fertilised old growth forest in Central Amazon. Data was collected in a full factorial nutrient addition experiment (nitrogen, phosphorus and cation treatments). Within each plot we have installed five litter traps of 50 cm x 50 cm, 1 m above ground, occupying an area of 1.25 m2 per plot, and ensuring litter reaching the trap was produced within the experimental plot area. The study was funded by...

Data are presented showing litterfall ant species and abundance from a plot based fertilisation experiment. The experiment was carried out at the Biological Dynamics of Forest Fragments Project (BDFFP) approximately 100 km north of Manaus. Data were collected in October 2018 and September 2019 by Santos-Neto. Sampling was carried out using a Wrinkler extractor. The data were collected to investigate the possible effects of different fertiliser applications on litterfall ant species and abundance. The work...

Data from: The evolution of polymorphism in the warning coloration of the Amazonian poison frog Adelphobates galactonotus

Diana Rojas, Paolo Momigliano, Albertina Pimentel Lima, Pedro Ivo Simões, Rachel Y. Dudaniec, Teresa C. S. Avila-Pires, Marinus S. Hoogmoed, Youszef O. C. Bitar, Igor Luis Kaefer, Adolfo Amézquita & Adam Stow
While intraspecific variation in aposematic signals can be selected for by different predatory responses, their evolution is also contingent on other processes shaping genetic variation. We evaluate the relative contributions of selection, geographic isolation and random genetic drift to the evolution of aposematic color polymorphism in the poison frog Adelphobates galactonotus, distributed throughout eastern Brazilian Amazonia. Dorsal coloration was measured for 111 individuals and genetic data were obtained from 220 individuals at two mitochondrial genes...

Data from: Why is Amazonia a ‘source’ of biodiversity? climate-mediated dispersal and synchronous speciation across the Andes in an avian group (Tityrinae)

Lukas J. Musher, Mateus Ferreira, Anya L. Auerbach, Jessica McKay & Joel Cracraft
Amazonia is a ‘source’ of biodiversity for other Neotropical ecosystems, but which conditions trigger in situ speciation and emigration is contentious. Three hypotheses for how communities have assembled include (1) a stochastic model wherein chance dispersal events lead to gradual emigration and species accumulation, (2) diversity-dependence wherein successful dispersal events decline through time due to ecological limits, and (3) barrier displacement wherein environmental change facilitates dispersal to other biomes via transient habitat corridors. We sequenced...

Data from: The role of physical barriers in the location of avian suture zones in the Guiana Shield, northern Amazonia

Luciano Nicholas Naka, Catherine L. Bechtoldt, L. Magalli Pinto Henriques, Robb T. Brumfield & Luciano Nicolas Naka
Suture zones represent natural forums to examine the role of geography and ecology in the speciation process. Here, we conduct a comparative analysis designed to investigate the location of avian phylogeographic breaks and contact zones in the Guiana Shield, northern Amazonia. We use distributional and genetic data from 78 pairs of avian taxa to address whether phylogeographic breaks and contact zones are associated with contemporary landscape features. Using spatially explicit statistical models, we found that...

Data from: Using river color to predict Amazonian floodplain forest avifauna in the world’s largest black-water river basin

Thiago Orsi Laranjeiras, Luciano Nicolas Naka & Mario Cohn-Haft.
Despite the importance of rivers in Amazonian biogeography, avian distribution patterns in river-created habitats (i.e., floodplain forest) have been sparsely addressed. Here we explore geographic variation in floodplain forest avifauna, specifically regarding one of the most striking aspects of the Amazon: the diversity of river “colors” (i.e., types, based on the color of the water). We sampled the avifauna at 30 sites, located in 17 different rivers (nine black- and eight white-water), in the Rio...

An empirical evaluation of camera trap study design: how many, how long, and when?

Roland Kays, Brian Arbogast, Megan Baker-Whatton, Chris Beirne, Hailey Boone, Mark Bowler, Santiago Burneo, Michael Cove, Ping Ding, Santiago Espinosa, André Gonçalves, Christopher Hansen, Patrick Jansen, Joseph Kolowski, Travis Knowles, Marcela Lima, Joshua Millspaugh, William McShea, Krishna Pacifici, Arielle Parsons, Brent Pease, Francesco Rovero, Fernanda Santos, Stephanie Schuttler, Douglas Sheil … & Wilson Spironello
1. Camera traps deployed in grids or stratified random designs are a well-established survey tool for wildlife but there has been little evaluation of study design parameters. 2. We used an empirical subsampling approach involving 2225 camera deployments run at 41 study areas around the world to evaluate three aspects of camera trap study design (number of sites, duration and season of sampling) and their influence on the estimation of three ecological metrics (species richness,...

The Influence of Environmental Variation on the Genetic Structure of a Poison Frog Distributed Across Continuous Amazonian Rainforest

Anthony Ferreira, Albertina Lima, Robert Jehle, Miquéias Ferrão & Adam Stow
Biogeographic barriers such as rivers have been shown to shape spatial patterns of biodiversity in the Amazon basin, yet relatively little is known about the distribution of genetic variation across continuous rainforest. Here, we characterize the genetic structure of the brilliant-thighed poison frog (Allobates femoralis) across an 880-km-long transect along the Purus-Madeira interfluve south of the Amazon river, based on 64 individuals genotyped at 7609 single-nucleotide polymorphism loci. A population tree and clustering analyses revealed...
