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...

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...

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...

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...

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: 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...

Attractive males are cautious and better learners in the sailfin tetra

Kalebe Pinto, David Saenz, Elio Borghezan & Tiago Pires
A major component of Darwin's formulation of sexual selection theory is whether mate choice can contribute to the evolution of cognitive abilities. Although a correlation between cognition and attractive traits has commonly been reported, the processes that generate such associations remain elusive. Here, we investigated female preference, neophobia and spatial learning in the sailfin tetra, Crenuchus spilurus, a sexually dimorphic fish. Females chose the most ornamented males, which were also more neophobic. This is in...

Final matrices: SNPs and mtDNA of Synallaxis albigularis / Mazaria propinqua

Waleska Barbosa
Differentiated habitat use can predict the diversity and genetic structure of Amazonian birds. Making this link between the intrinsic characteristics of organisms and the patterns of genetic diversity can provide us with insights into the evolutionary processes that act on species and also on the history of environments. About 15% of non-aquatic birds in the Amazon are restricted to river-created habitats, and have different levels of habitat affinity. In this study we investigated the evolutionary...

Admixture may be extensive among hyperdominant Amazon rainforest tree species

Drew Larson, Oscar Vargas, Alberto Vicentini & Christopher W. Dick
Admixture is a mechanism by which species of long-lived plants may acquire novel alleles. However, the potential role of admixture in the origin and maintenance of tropical plant diversity is unclear. We ask whether admixture occurs in an ecologically important clade of Eschweilera (Parvifolia clade, Lecythidaceae), which includes some of the most widespread and abundant tree species in Amazonian forests. Using target capture sequencing, we conducted a detailed phylogenomic investigation of 33 species in the...

Pied tamarins go multimodal in response to anthropogenic noise

Tainara Sobroza, Jacob Dunn, Marcelo Gordo & Adrian Barnett
Sounds produced by human activities are often loud and may mask acoustic signals used by other species for communication. To circumvent this, animals may use various strategies, including shifting modality completely or complementing acoustic information by also using another modality of communication. Here we tested the overlooked multimodal shift hypothesis using pied tamarins (Saguinus bicolor) as models. We predicted that in noisier areas the species would exhibit more scent marking behaviour (i.e., olfactory communication), while...
