Pérez-García, Rodrigo Muñoz, Eunice Romero-Pérez, Ana Andrade, José Luis Andrade, Patricia Balvanera, Justin M. Becknell, Tony V. Bentos, Radika Bhaskar, Frans Bongers, Vanessa Boukili, Pedro H. S. Brancalion, Ricardo G. César, Deborah A. Clark, David B. Clark, Dylan Craven, Alexander DeFrancesco, Juan M. Dupuy, Bryan Finegan … & G. Bruce Williamson
1. Successional gradients are ubiquitous in nature, yet few studies have systematically examined the evolutionary origins of taxa that specialize at different successional stages. Here we quantify successional habitat specialization in Neotropical forest trees and evaluate its evolutionary lability along a precipitation gradient. Theoretically, successional habitat specialization should be more evolutionarily conserved in wet forests than in dry forests due to more extreme microenvironmental differentiation between early and late successional stages in wet forest. 2....

Data from: Predicted 2100 climate scenarios affects growth and skeletal development of tambaqui (Colossoma macropomum) larvae

Ivã G. Lopes, Thyssia B. Araújo-Dairiki, Juliana T. Kojima, Adalberto L. Val & Maria C. Portella
Climate changes driven by greenhouse gas emissions have been occurring in an accelerated degree, affecting environmental dynamics and living beings. Among all affected biomes, the Amazon is particularly subjected to adverse impacts, such as temperature rises and water acidification. This study aimed to evaluate the impacts of predicted climate change on initial growth and development of an important Amazonian food fish, the tambaqui. We analyzed growth performance, and monitored the initial osteogenic process and the...

Data from: Human management and hybridization shape treegourd fruits in the Brazilian Amazon Basin

Priscila Ambrosio Moreira, Cédric Mariac, Leila Zekraoui, Marie Couderc, Doriane Picanco Rodrigues, Charles R. Clement & Yves Vigouroux
Local people's perceptions of cultivated and wild agrobiodiversity, as well as their management of hybridization are still understudied in Amazonia. Here we analyze domesticated treegourd (Crescentia cujete), whose versatile fruits have technological, symbolic and medicinal uses. A wild relative (C. amazonica) of the cultivated species grows spontaneously in Amazonian flooded forests. We demonstrated, using whole chloroplast sequences and nuclear microsatellites, that the two species are strongly differentiated. Nonetheless, they hybridize readily throughout Amazonia and the...

Palms and trees resist extreme drought in Amazon forests with shallow water tables

Thaiane Sousa, Juliana Schietti, Fernanda Coelho De Souza, Adriane Esquivel-Muelbert, Igor Ribeiro, Thaise Emilio, Pedro Pequeno, Oliver Phillips & Flavia Costa
1. The intensity and frequency of severe droughts in the Amazon region has increase in recent decades. These extreme events are associated with changes in forest dynamics, biomass and floristic composition. However, most studies of drought response have focused on upland forests with deep water tables, which may be especially sensitive to drought. Palms, which tend to dominate the less well-drained soils, have also been neglected. The relative neglect of shallow water tables and palms...

Data from: Historical demography and climate driven distributional changes in a widespread Neotropical freshwater species with high economic importance

Manolo Perez, Ezequiel Oliveira, Luiz Bertollo, Carla Gestich, Petr Rab, Tariq Ezaz, Fernando Souza, Patrik Viana, Eliana Feldberg, Edivaldo Herculano Correa De Oliveira & Marcelo Cioffi
The Neotropical region exhibits the greatest worldwide diversity and the diversification history of several clades is related to the puzzling geomorphologic and climatic history of this region. The freshwater Amazon ecoregion contains the main hydrographic basins of the Neotropical region that are highly dendritic and ecologically diverse. It contains a rich and endemic fish fauna, including one of its most iconic and economically important representatives, the bony-tongue Arapaima gigas (Teleostei, Osteoglossiformes). Here, we evaluated the...

Data from: Long-term change in the avifauna of undisturbed Amazonian rainforest: Ground-foraging birds disappear and the baseline shifts

Cameron Rutt, Philip Stouffer, Vitek Jirinec, Richard Bierregaard, Angélica Hernández-Palma, Erik Johnson, Stephen Midway, Luke Powell, Jared Wolfe & Thomas Lovejoy
How are rainforest birds faring in the Anthropocene? We use bird captures spanning >35 years from 55 sites within a vast area of intact Amazonian rainforest to reveal reduced abundance of terrestrial and near-ground insectivores in the absence of deforestation, edge effects, or other direct anthropogenic landscape change. Because undisturbed forest includes far fewer terrestrial and near-ground insectivores than it did historically, today’s fragments and second growth are more impoverished than shown by comparisons with...

Recent population differentiation in the habitat specialist Glossy Antshrike (Aves: Thamnophilidae) across Amazonian seasonally flooded forests: Complete matrix

Sofia Silva, Camila Ribas & Alexandre Aleixo
We assessed population structure and the spatio-temporal pattern of diversification in the Glossy Antshrike Sakesphorus luctuosus (Aves, Thamnophilidae) to understand the processes shaping the evolutionary history of Amazonian floodplains and address unresolved taxonomic controversies surrounding its species limits. By targeting ultraconserved elements (UCEs) from 32 specimens of S. luctuosus, we identified independent lineages and estimated their differentiation, divergence times and migration rates. We also estimated current and past demographic histories for each recovered lineage. We...

Soil macroinvertebrate communities have been assessed worldwide using the standard ISO/TSBF sampling procedure. The Macrofauna database currently comprises 3694 sites distributed throughout 41 countries, from 55º S latitude to 57ºN, sea level to over 4000m in elevation, in total annual total rainfall regimes between 500 and >3000mm and 5 to 32ºC mean temperature. These communities are significantly influenced by climatic parameters, soil texture and vegetation cover. Abundance and diversity were highest in tropical rain forests...

Data from: Effects of a major Amazonian river confluence on the distribution of floodplain forest avifauna

Thiago Laranjeiras, Luciano Naka, Gabriel Leite & Mario Cohn-Haft
Aim: Although “river color” or water type is an important determinant of Amazonian floodplain biodiversity, the relevance of mixing distinct water types at river confluences to the distribution of terrestrial floodplain fauna has been largely overlooked. We investigated how the influx of a sediment-rich whitewater tributary affects the floodplain forest avifauna along the world’s largest blackwater river. Location: Northwestern Brazilian Amazon Taxon: Birds Methods: We sampled floodplain avifauna and retrieved estimates of sediment concentration in...

Chazdon, Dylan Craven, Jarcilene S. De Almeida-Cortez, George A. L. Cabral, Ben H. J. De Jong, Julie S. Denslow, Daisy H. Dent, Saara J. DeWalt, Juan M. Dupuy, Sandra M. Durán, Mario M. Espírito-Santo, María C. Fandino, Ricardo G. César, Jefferson S. Hall, José Luis Hernandez-Stefanoni, Catarina C. Jakovac … & Danaë M. A. Rozendaal
Land-use change occurs nowhere more rapidly than in the tropics, where the imbalance between deforestation and forest regrowth has large consequences for the global carbon cycle1. However, considerable uncertainty remains about the rate of biomass recovery in secondary forests, and how these rates are influenced by climate, landscape, and prior land use2, 3, 4. Here we analyse aboveground biomass recovery during secondary succession in 45 forest sites and about 1,500 forest plots covering the major...

Data from: Reproductive traits as predictors of assembly chronosequence patterns in epiphyllous bryophyte metacommunities

Adriel M. Sierra, José Julio Toledo, Noris Salazar Allen & Charles E. Zartman
1) Understanding the mechanisms underlying species assembly is a central focus of plant ecology and is crucial to revealing how plant communities are structured. However, the temporal limitations of most terrestrial plant communities preclude collection of species assembly data in a tractable time-frame. 2) The aim of this study is to investigate the importance of dispersal potential, as estimated by inter-specific variation in sexual and asexual expression, as a predictor of patch chronosequence assembly for...

Data from: Is environmental legislation conserving tropical stream faunas? a large-scale assessment of local, riparian and catchment-scale influences on Amazonian stream fish

Cecília G. Leal, Jos Barlow, Toby Gardner, Robert M. Hughes, Rafael P. Leitão, Ralph Mac Nally, Philip R. Kaufmann, Silvio F. B. Ferraz, Jansen Zuanon, Felipe R. De Paula, Joice Ferreira, James R. Thomson, Gareth D. Lennox, Eurizângela P. Dary, Cristhiana P. Röpke, Paulo S. Pompeu & Toby A. Gardner
1.Agricultural expansion and intensification are major threats to tropical biodiversity. In addition to the direct removal of native vegetation, agricultural expansion often elicits other human-induced disturbances, many of which are poorly addressed by existing environmental legislation and conservation programmes. This is particularly true for tropical freshwater systems, where there is considerable uncertainty about whether a legislative focus on protecting riparian vegetation is sufficient to conserve stream fauna. 2.To assess the extent to which stream fish...

Data from: Conspicuousness, color resemblance, and toxicity in geographically diverging mimicry: the pan-Amazonian frog Allobates femoralis

Adolfo Amézquita, Óscar Ramos, Mabel Cristina González, Camilo Rodríguez, Iliana Medina, Pedro Ivo Simões & Albertina Pimentel Lima
Predation risk is allegedly reduced in Batesian and Müllerian mimics, because their coloration resembles the conspicuous coloration of unpalatable prey. The efficacy of mimicry is thought to be affected by variation in the unpalatability of prey, the conspicuousness of the signals, and the visual system of predators that see them. Many frog species exhibit small colorful patches contrasting against an otherwise dark body. By measuring toxicity and color reflectance in a geographically variable frog species...

Data from: Patterns of nitrogen-fixing tree abundance in forests across Asia and America

Duncan N. L. Menge, Ryan A. Chisholm, Stuart J. Davies, Kamariah Abu Salim, David Allen, Mauricio Alvarez, Norm Bourg, Warren Y. Brockelman, Sarayudh Bunyavejchewin, Nathalie Butt, Min Cao, Wirong Chanthorn, Wei-Chun Chao, Keith Clay, Richard Condit, Susan Cordell, João Batista Da Silva, H. S. Dattaraja, Ana Cristina Segalin De Andrade, Alexandre A. Oliveira, Jan Den Ouden, Michael Drescher, Christine Fletcher, Christian P. Giardina, C. V. Savitri Gunatilleke … & Tak Fung
Symbiotic nitrogen (N)‐fixing trees can provide large quantities of new N to ecosystems, but only if they are sufficiently abundant. The overall abundance and latitudinal abundance distributions of N‐fixing trees are well characterised in the Americas, but less well outside the Americas. Here, we characterised the abundance of N‐fixing trees in a network of forest plots spanning five continents, ~5,000 tree species and ~4 million trees. The majority of the plots (86%) were in America...

Data from: Maintenance of genetic and morphological identity in two sibling Syrrhopodon species (Calymperaceae, Bryopsida) despite extensive introgression

Marta R. Pereira, Alice Ledent, Patrick Mardulyn, Charles E. Zartman & Alain Vanderpoorten
Bryophytes are a group of land plants wherein the role of hybridization has long been challenged. Using Genotyping by Sequencing to circumvent the lack of molecular variation at selected loci previously used for phylogeny and morphology, we determine the level of genetic and morphological divergence and reproductive isolation between the sibling Syrrhopodon annotinus and S. simmondsii (Calymperaceae, Bryopsida) that occur in sympatry but in different habitats in lowland Amazonian rainforests. A clear morphological differentiation and...

Hidden in the DNA: insights on how multiple historical processes and natural history traits shaped patterns of cryptic diversity in an Amazon leaf-litter lizard Loxopholis osvaldoi (Squamata: Gymnophthalmidae).

Sergio Marques De Souza, Katia Machado Pellegrino, Tuliana Oliveira Brunes, Ana Carnaval, Roberta Pacheco Damasceno, Manoela Lima De Oliveira Borges, Carlos Candia Gallardo & Miguel Rodrigues
Aim: To investigate cryptic diversity and diversification timing in the putatively low-dispersal Amazonian leaf-litter lizard Loxopholis osvaldoi, and to ask how geography (rivers, isolation by distance, IBD), ecological drivers (isolation by environment, IBE) and historical factors (climatic refugia) explain intraspecific genetic variation. Location: Central Amazonia, Brazil. Taxon: Squamata; Gymnophthalmidae; Loxopholis osvaldoi. Methods: We sequenced two mitochondrial and two nuclear markers in 157 individuals. Phylogeographic structure and the occurrence of independent evolving lineages where explored through...

Time of activity is a better predictor of the distribution of a tropical lizard than pure environmental temperatures

Gabriel Henrique De Oliveira Caetano, Juan Carlos Santos, Leandro Godinho, Vitor Cavalcante, Luisa Viegas, Pedro Campelo, Lidia Martins, Alan De Oliveira, Júlio Alvarenga, Helga Wiederhecker, Verônica De Novaes E Silva, Fernanda Werneck, Donald Miles, Guarino Colli & Barry Sinervo
Environmental temperatures influence ectotherms’ physiology and capacity to perform activities necessary for survival and reproduction. Time available to perform those activities is determined by thermal tolerances and environmental temperatures. Estimates of activity time might enhance our ability to predict suitable areas for species’ persistence in face of climate warming, compared to the exclusive use of environmental temperatures, without considering thermal tolerances. We compare the ability of environmental temperatures and estimates of activity time to predict...

A “Dirty” Footprint: Soil macrofauna biodiversity and fertility in Amazonian Dark Earths and adjacent soils

Wilian C. Demetrio, Ana C. Conrado, Agno N. S. Acioli, Alexandre C. Ferreira, Marie L. C. Bartz, Samuel W. James, Elodie Silva, Lilianne S. Maia, Gilvan C. Martins, Rodrigo S. Macedo, David W. G. Stanton, Patrick Lavelle, Elena Velasquez, Anne Zangerlé, Rafaella Barbosa, Sandra C. Tapia‐Coral, Aleksander W. Muniz, Alessandra Santos, Talita Ferreira, Rodrigo F. Segalla, Thibaud Decaëns, Herlon S. Nadolny, Clara P. Peña‐Venegas, Cláudia M. B. F. Maia, Amarildo Pasini … & George G. Brown
Amazonian rainforests once thought to hold an innate pristine wilderness, are increasingly known to have been densely inhabited by populations showing a diverse and complex cultural background prior to European arrival. To what extent these societies impacted their landscape is unclear. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Basin, created by pre-Columbian societies as a result of more sedentary habits. Much is known of the chemistry of these soils, yet their...

Juggling options: manipulation ease determines primate optimal fruit size choice

Renann H. P. Dias-Silva, Matheus J. Castro Sa, Fabricio B. Baccaro, Pavel Tománek & Adrian A. Barnett
Optimal foraging theory predicts that animals will seek simultaneously to minimize food processing time and maximize energetic gain. To test this hypothesis, we evaluated whether a specialist seed-predator primate forages optimally when choosing among variable-sized thick-husked fruits. Our objects of study were the golden-backed-uacari (Cacajao ouakary, Pitheciidae) and single seeded pods of the macucu tree (Aldina latifolia, Fabaceae). We predicted that golden-backed-uacari will consume fruits of the size class that requires the least time to...

eDNA in a bottleneck: obstacles to fish metabarcoding studies in megadiverse freshwater systems

Jake Jackman, Chiara Benvenuto, Ilaria Coscia, Cintia Carvalho, Jonathan Ready, Jean Boubli, William Magnusson, Allan McDevitt & Naiara Sales
The current capacity of environmental DNA (eDNA) to provide accurate insights into the biodiversity of megadiverse regions (e.g., the Neotropics) requires further evaluation to ensure its reliability for long-term monitoring. In this study, we first evaluated the taxonomic resolution capabilities of a short fragment from the 12S rRNA gene widely used in fish eDNA metabarcoding studies, and then compared eDNA metabarcoding data from water samples with traditional sampling using nets. For the taxonomic discriminatory power...

Species abundances and functional traits data of frog assemblages in Amazonian forests (Tapajós FLONA and Alter do Chão village, Brazil)

Kelly Torralvo, Rafael De Fraga, Albertina Lima & William Magnusson
We sampled frogs along an edaphic and vegetation-structure gradient in the Brazilian Amazon. We sampled 33 plots organized in four modules (with 10, 6, 8 and 9 plots). Environmental data are composed of are litter depht(cm), distance to water bodies (m), temperature (ºC), vegetation structure (PCA axis), soil sand and silt content (g-kg), and proportion of the area deforested. Additionally, we measured snout-vent length (SVL) and leg length relative to SVL and evaluated the effects...

High-resolution hydraulic parameter maps for surface soils in tropical South America

T. Marthews, C.A. Quesada, D.R. Galbraith, Y. Malhi, C.E. Mullins, M.G. Hodnett & I. Dharssi
Spatial data files holding gridded parameter maps of surface soil hydraulic parameters derived from a selection of pedotransfer functions. Modern land surface model simulations capture soil profile water movement through the use of soil hydraulics sub-models, but good hydraulic parameterisations are often lacking - especially in the tropics - and it is this lack that we fill here in the context of South America. Optimal hydraulic parameter values are given for the Brooks and Corey,...
