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...

Variation in the production of plant tissues bearing extrafloral nectaries explains temporal patterns of ant attendance in Amazonian understory plants

Anselmo Nogueira, Fabricio Baccaro, Laura Leal, Pedro Rey, Lúcia Lohmann & Judith Bronstein
1. Information on direct and indirect drivers of temporal variation in ant-plant interactions is scarce, compromising our ability to predict the functioning of these ecologically important interactions. 2. We investigated the roles of precipitation, ant activity, abundance of young plant tissues bearing extrafloral nectaries (EFNs), and EFN phenotypes in the establishment of EFN-mediated ant-plant interactions throughout the year in Amazonia, Brazil. We hypothesized that the frequency of ant-plant interactions follows a predictable seasonal pattern, being...

Diversification history of clown tree frogs in Neotropical rainforests (Anura, Hylidae, Dendropsophus leucophyllatus group)

Renata Pirani, Pedro Peloso, Joyce Prado, Érico Polo, Lacey Knowles, Santiago Ron, Miguel Rodrigues, Marcelo Sturaro & Fernanda Werneck
General consensus emphasizes that no single biological process can explain the patterns of species’ distributions and diversification in the Neotropics. Instead, the interplay of several processes across space and time must be taken into account. Here we investigated the phylogenetic relationships and biogeographic history of tree frogs in the Dendropsophus leucophyllatus species group (Amphibia: Hylidae), which is distributed across Amazonia and the Atlantic rainforests. Using Next Generation Sequencing (NGS) and double digest restriction-site associated DNA...

Data from Queiroz et al 2022 Biotropica Ant diversity decreases during the dry season: a meta-analysis of the effects of seasonality on ant richness and abundance Abstract Tropical studies traditionally describe insect diversity variation throughout the year. The temporally structured responses of insect assemblages to climate seasonality vary across ecosystems due to gradients of resource availability and limiting ecological factors. These idiosyncratic responses might be particularly true across the vast geographical range of the Brazilian...

Santiago Ramos & Maria Lopes
Euterpe precatoria is a palm tree belonging to the Arecaceae family, occurring in Western and Central Brazilian Amazonia Its fruit, which is very appreciated in the Amazon region, produces pulp that is consumed in fresh form. Its production is carried out almost exclusively by extractive farmers. In order to establish adequate strategies to sustain this genetic resource. We need knowledge about its diversity and genetic structure in natural populations. This study aimed to evaluate the...

Islands in a green ocean: spatially structured endemism in Amazonian white-sand vegetation

Flavio Costa, Mario Terra-Araújo, Charles Zartman, Cintia Cornelius, Fernanda Carvalho, Michael Hopkins, Pedro Viana, Eduardo Prata & Alberto Vicentini
Here, we examine the influence of the spatial distribution of open White-Sand Campina (WSC) in the Amazon on the species richness and beta-diversity of their vascular plants. It is well known that beta-diversity tends to increase with geographical distance, but the influence of habitat insularity on floristic composition and endemism is still unclear. We surveyed WSC in Central and Southwestern Amazon, generating lists of species occurrences by rapid-inventory techniques to evaluate the influence of island...

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...

Shallow population structure and shared phylogeographic and demographic patterns in seven Amazonian White-Sand ecosystems birds

João Marcos Guimarães Capurucho, Mary Ashley, Cintia Cornelius, Sérgio Borges, Camila Ribas & John Bates
White-sand ecosystems (WSE) have a patchy distribution throughout Amazonia and harbor a specialized community of birds. The patchiness of WSE lead to the expectation of highly fragmented and isolated populations across Amazonia. Additionally, the sandy substrate could render these ecosystems vulnerable climatic changes. We performed a comparative phylogeographic study of seven WSE birds using Ultra-conserved elements to evaluate their relation to Amazonian environmental and landscape history and the occurrence of shared patterns. Genetic structure varied...

Abstract Sjogren's syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration of the exocrine glands and other organs, associated with sicca syndrome but also with systemic involvement with varying degrees of severity. Despite their importance, some systemic manifestations, mainly liver, gastrointestinal, and pancreatic are not routinely evaluated. To address these manifestations, the Sjögren's Syndrome Committee of the Brazilian Society of Rheumatology conducted a broad systematic review of the literature on studies investigating prevalence and...

Data from Queiroz et al Reduction in ant diversity during the dry season: a meta-analysis of the effects of seasonality on ant richness and abundance Abstract Tropical studies present seasonal variation of insect richness, density, and changes in species composition. However, responses of assemblages to climate change associated with seasons may not follow the same patterns across ecosystems due to biotic and abiotic factors (e.g., resources and conditions). These idiosyncratic responses might be particularly true...

Data from: Divergent natural selection with gene flow along major environmental gradients in Amazonia: insights from genome scans, population genetics and phylogeography of the characin fish Triportheus albus

Georgina M. Cooke, Ning L. Chao & Luciano B. Beheregaray
The unparalleled diversity of tropical ecosystems like the Amazon Basin has been traditionally explained using spatial models within the context of climatic and geological history. Yet, it is adaptive genetic diversity that defines how species evolve and interact within an ecosystem. Here we combine genome scans, population genetics and sequenced-based phylogeographic analyses to examine spatial and ecological arrangements of selected and neutrally evolving regions of the genome of an Amazonian fish, Triportheus albus. Using a...

Data from: Genetic evidence for polygamy as a mating strategy in Caiman crocodilus

Deyla Oliveira, Boris Marioni, Izeni Farias & Tomas Hrbek
The mating system of the spectacled caiman (Caiman crocodilus) was investigated in the Piagaçu-Purus Sustainable Development Reserve, Amazonas, Brazil. We used six polymorphic microsatellite loci to genotype 15 females and 174 hatchlings representing 20 nests sampled over four consecutive reproductive seasons (2007 to 2010). Paternity was determined by two methods: simple counts, and statistical analysis using Gerud 2.0. Results were congruent between the two approaches, and the null hypothesis of single paternity was rejected in...

Data from: Known knowns, known unknowns, unknown unknowns and unknown knowns in DNA barcoding: a comment on Dowton et al.

Rupert A. Collins & Robert H. Cruickshank
In a recent commentary, Dowton et al. (2014) propose a framework for "next-generation" DNA barcoding, whereby multi-locus datasets are coupled with coalescent-based species delimitation methods to make specimen identifications. They claim single-locus DNA barcoding is outdated, and a multilocus approach superior, with their assertions supported by an analysis of 33 species of Sarcophaga flesh flies. Here, we reanalyse their data and show that a standard DNA barcode analysis is in fact capable of identifying 99.8%...

Data from: Intraspecific and interspecific trait variability in tadpole metacommunities from the Brazilian Atlantic rainforest

Mainara Xavier Jordani, Nicolas Mouquet, Lilian Casatii, Marcelo Menin, Denise De Cerqueira Rossa-Feres & Cécile H. Albert
1. A better understanding of species coexistence and community dynamics may benefit from more insights on trait variability at the individual and species levels. 2. Tadpole assemblages offer an excellent system to understand the relative influence of intra- and interspecific variability on community assembly, due to their high phenotypic plasticity, and the strong influence that environmental variables have on their spatial distribution and individual performance. 3. Here we quantified the intra- and interspecific components of...
