Data from: Geological and climatic changes in quaternary shaped the evolutionary history of Calibrachoa heterophylla, an endemic South-Atlantic species of petunia

Geraldo Mäder, Jéferson N. Fregonezi, Aline P. Lorenz-Lemke, Sandro L. Bonatto & Loreta B. Freitas
Background: The glacial and interglacial cycles that characterized the Quaternary greatly affected the distribution and genetic diversity of plants. In the Neotropics, few phylogeographic studies have focused on coastal species outside of the Atlantic Rainforest. Climatic and sea level changes during the Quaternary played an important role in the evolutionary history of many organisms found in coastal regions. To contribute to a better understanding of plant evolution in this environment in Southern South America, we...

Data from: Phylogenomic evidence for ancient hybridization in the genomes of living cats (Felidae)

Gang Li, Brian W. Davis, Eduardo Eizirik & William J. Murphy
Interspecies hybridization has been recently recognized as potentially common in wild animals, but the extent to which it shapes modern genomes is still poorly understood. Distinguishing historical hybridization events from other processes leading to phylogenetic discordance among different markers requires a well-resolved species tree that considers all modes of inheritance, and overcomes systematic problems due to rapid lineage diversification by sampling large genomic character sets. Here we assessed genome-wide phylogenetic variation across a diverse mammalian...

Data from: Origin and hidden diversity within the poorly known Galápagos snake radiation (Serpentes: Dipsadidae)

Hussam Zaher, Mario H. Yánez-Munõz, Miguel T. Rodrigues, Roberta Graboski, Fabio A. Machado, Marco Altamirano-Benavides, Sandro L. Bonatto & Felipe G. Grazziotin
Galápagos snakes are among the least studied terrestrial vertebrates of the Archipelago. Here, we provide a phylogenetic analysis and a time calibrated tree for the group, based on a sampling of the major populations known to occur in the Archipelago. Our study revealed the presence of two previously unknown species from Santiago and Rábida Islands, and one from Tortuga, Isabela, and Fernandina. We also recognize six additional species of Pseudalsophis in the Galápagos Archipelago (Pseudalsophis...

Data from: Unraveling B-lymphocytes in CNS inflammatory diseases: Distinct mechanisms and treatment targets

Bruna Klein Da Costa, Renata Brant De Souza Melo, Giordani Rodrigues Dos Passos, Douglas Gomes Meneses Sevilha Castro, Jefferson Becker, Amit Bar-Or & Douglas Kazutoshi Sato
Specific therapies targeting B lymphocytes in multiple sclerosis (MS) have demonstrated reductions in disease activity and disability progression. Several observational studies have also shown the effects of targeting B lymphocytes in other rare CNS inflammatory diseases, such as neuromyelitis optica spectrum disorder (NMOSD) and autoimmune encephalitis (AE). However, some drugs targeting cytokine receptors involved in B-lymphocyte maturation and proliferation resulted in negative outcomes in MS. These apparently conflicting findings have stimulated research on the pathophysiologic...

Data from: Crop feeding by brown howlers (Alouatta guariba clamitans) in forest fragments: the conservation value of cultivated species

Óscar M. Chaves & Júlio César Bicca-Marques
Primates inhabiting human-modified habitats often complement their diets with cultivated species. Although this flexible foraging behavior reduces feeding stress in animals inhabiting small or low-quality habitats, its potential economic costs may promote negative human–nonhuman primate interactions. It is critical to assess the importance of cultivated species to primate diets, the factors influencing their exploitation, and their associated economic costs to evaluate the conservation value of cultivated species and the impact of crop feeding on human–nonhuman...

Data from: Quantity and quality of seed dispersal by a large arboreal frugivore in small and large Atlantic forest fragments

Óscar M. Chaves, Júlio César Bicca-Marques & Colin A. Chapman
Seed dispersal is a key process driving the structure, composition, and regeneration of tropical forests. Larger frugivores play a crucial role in community structuring by dispersing large seeds not dispersed by smaller frugivores. We assessed the hypothesis that brown howler monkeys (Alouatta guariba clamitans) provide seed dispersal services for a wide assemblage of plant species in both small and large Atlantic forest fragments. Although fruit availability often decreases in small fragments compared with large ones,...

Data from: Flower consumption, ambient temperature and rainfall modulate drinking behavior in a folivorous-frugivorous arboreal mammal

Óscar M. Chaves, Vanessa B. Fortes, Gabriela P. Hass, Renata B. Azevedo, Kathryn E. Stoner & Júlio César Bicca-Marques
In these datasets we provided information on the drinking behavior in 14 wild groups of brown howler monkeys (Alouatta guariba clamitans) inhabiting small, medium, and large Atlantic Forest fragments in southern Brazil. We provided two datasets: (1) full data on the drinking behavior of the 14 study groups, and (2) the dataset used to run the GLMMs described in the main manuscript. Overall, we found a wide variation in the mean rate of drinking among...

Negative impacts of dominance on bee communities: Does the influence of invasive honey bees differ from native bees?

Lucas Alejandro Garibaldi, Lucas Garibaldi, Néstor Pérez-Méndez, Guaraci Cordeiro, Alice Hughes, Michael Orr, Isabel Alves Dos Santos, Breno Freitas, Favízia Freitas De Oliveira, Gretchen Lebuhn, Ignasi Bartomeus, Marcelo Aizen, Patricia Andrade, Betina Blochtein, Danilo Boscolo, Patricia Drumond, Maria Gaglianone, Barbara Gemmill-Herren, Rosana Halinski, Cristiane Krug, Marcia Maues, Lucia Piedade Kiill, Mardiore Pinheiro, Carmen Pires & Blandina Felipe Viana
Invasive species can reach high abundances and dominate native environments. One of the most impressive examples of ecological invasions is the spread of the African sub-species of the honey bee throughout the Americas, starting from its introduction in a single locality in Brazil. The invasive honey bee is expected to more negatively impact bee community abundance and diversity than native dominant species, but this has not been tested previously. We developed a comprehensive and systematic...

Data from: The effect of habitat fragmentation on the genetic structure of a top predator: loss of diversity and high differentiation among remnant populations of Atlantic Forest jaguars (Panthera onca)

Taiana Haag, Anelisie Santos, Denis Sana, Ronaldo Morato, , , Carlos De Angelo, Mario Di Bitetti, Francisco Salzano & Eduardo Eizirik
Habitat fragmentation may disrupt original patterns of gene flow and lead to drift-induced differentiation among local population units. Top predators such as the jaguar may be particularly susceptible to this effect, given their low population densities, leading to small effective sizes in local fragments. On the other hand, the jaguar's high dispersal capabilities and relatively long generation time might counteract this process, slowing the effect of drift on local populations over the time frame of...

Data from: DNA barcoding meets molecular scatology: short mtDNA sequences for standardized species assignment of carnivore noninvasive samples

Paulo B. Chaves, Vanessa G. Graeff, Marília B. Lion, Larissa R. Oliveira & Eduardo Eizirik
Although species assignment of scats is important to study carnivoran biology, there is still no standardized assay for the identification of carnivores worldwide, which would allow large-scale routine assessments and reliable cross-comparison of results. Here we evaluate the potential of two short mtDNA fragments (ATP6 [126 bp] and COI [187 bp]) to serve as standard markers for the Carnivora. Samples of 66 species were sequenced for one or both of these segments. Alignments were complemented...

Data from: Population genetics of jaguars (Panthera onca) in the Brazilian Pantanal: molecular evidence for demographic connectivity on a regional scale

Fernanda Pedone Valdez, Taiana Haag, Fernando C. C. Azevedo, Leandro Silveira, Sandra M. C. Cavalcanti, Francisco M. Salzano & Eduardo Eizirik
Habitat loss and fragmentation are important threats to carnivores worldwide, and can be especially intense for large predators. Jaguars have already been extirpated from over half of their original area of distribution, and few regions still maintain large populations. For these, detailed understanding is crucial for setting appropriate recovery targets in impacted areas. The Pantanal is among the best examples of a region with a large jaguar population in a healthy environment. Here, we analyzed...

Data from: Habitat amount hypothesis and passive sampling explain mammal species composition in Amazonian river islands

Rafael M. Rabelo, Susan Aragón, Júlio César Bicca-Marques & Bruce W. Nelson.
Nested structures of species assemblages have been frequently associated with patch size and isolation, leading to the conclusion that colonization-extinction dynamics drives nestedness. The ‘passive sampling’ model states that the regional abundance of species randomly determines their occurrence in patches. The ‘habitat amount hypothesis’ also challenges patch size and isolation effects, arguing that they occur because of a 'sample area effect'. Here we (1) ask whether the structure of the mammal assemblages of fluvial islands...

Vastly underestimated radiation of Amazonian salamanders (Plethodontidae: Bolitoglossa) and implications about plethodontid diversification

Andres Felipe Jaramillo, Ignacio De La Riva, Juan M. Guayasamin, Juan C. Chaparro, Giussepe Gagliardi-Urrutia, Roberto Gutierrez, Isabela Brcko, Carles Vila & Santiago Castroviejo-Fisher
We present data showing that the number of salamander species in Amazonia is vastly underestimated. We used DNA sequences of up to five genes (3 mitochondrial and 2 nuclear) of 366 specimens, 189 corresponding to 89 non-Amazonian nominal species and 177 Amazonian specimens, including types or topotypes, of eight of the nine recognized species in the region. By including representatives of all known species of Amazonian Bolitoglossa, except for one, and 73 % of the...

Mechanisms for color convergence in a mimetic radiation of poison frogs

Evan Twomey, Morgan Kain, Myriam Claeys, Kyle Summers, Santiago Castroviejo-Fisher & Ines Van Bocxlaer
In animals, bright colors often evolve to mimic other species when a resemblance is selectively favored. Understanding the proximate mechanisms underlying such color mimicry can give insights into how mimicry evolves, for example, whether color convergence evolves from a shared set of mechanisms or through the evolution of novel color production mechanisms. We studied color production mechanisms in poison frogs (Dendrobatidae), focusing on the mimicry complex of Ranitomeya imitator. Using reflectance spectrometry, skin pigment analysis,...

Phylogenomic discordance in the Eared Seals is best explained by incomplete lineage sorting following explosive radiation in the Southern Hemisphere

Fernando Lopes, Larissa Oliveira, Amanda Kessler, Yago Beux, Enrique Crespo, Susana Cárdenas-Alayza, Patricia Majluf, Maritza Sepulveda, , Valentina Franco-Trecu, Diego Paez-Rosas, Jaime Chaves, Carolina Loch, Bruce Robertson, Karina Acevedo-Whitehouse, Fernando Elorriaga-Verplancken, Stephen Kirkman, Claire Peart, Jochen Wolf & Sandro Bonatto
The phylogeny and systematics of fur seals and sea lions (Otariidae) have long been studied with diverse data types, including an increasing amount of molecular data. However, only a few phylogenetic relationships have reached acceptance pointing at strong gene-tree species tree discordance. Divergence times in the group also vary largely between studies. These uncertainties impeded the understanding of the biogeographical history of the group, such as when and how trans-equatorial dispersal and subsequent speciation events...
