Ana Julia Pinto Fonseca S. Afonso, António Pinto-Almeida, Tiago M. F. Mendes, Pedro Ferreira, Silvana Belo, Fernanda F. Anibal, Silmara M. Allegretti, Carlos Alexandre Galinaro, Emanuel Carrilho & Ana B Abecassis
The extensive use of Praziquantel (PZQ), the only drug available to treat schistosomiasis, has brought concern about the emergence of PZQ-resistance/tolerance by Schistosoma spp., thus reaffirming an urge for the development of new treatment alternatives. Therefore, it is imperative and urgent to study this phenomenon trying to understand what is involved in its occurrence. Studies of Schistosoma spp. genome, transcriptome and proteome are crucial to better understand this situation. By stepwise drug pressure from a...

Data from: Genetic and paleomodelling evidence of the population expansion of the cattle egret Bubulcus ibis in Africa during the climatic oscillations of the Late Pleistocene

Carlos Congrains, Antônio F. Carvalho, , Graeme S. Cumming, Dominic A. W. Henry, Shiiwua A. Manu, Jacinta Abalaka, Cristiano D. Rocha, Moussa S. Diop, Joãozinho Sá, Hamilton Monteiro, Lars H. Holbech, Francis Gbogbo & Silvia N. Del Lama
Increasing aridity during glacial periods produced the retraction of forests and the expansion of arid and semi-arid environments in Africa, with consequences for birds. Cattle egret (Bubulcus ibis) is a dispersive species that prefers semiarid environments and requires proximity to bodies of water. We expected that climatic oscillations led to the expansion of the range of the cattle egret during arid periods, such as the Last Maximum Glacial (LGM) and contraction of distribution during the...

Maintaining genetic integrity with high promiscuity: Frequent hybridization with low introgression in multiple hybrid zones of Melocactus(Cactaceae)

Khan Gulzar, Evandro Marsola De Moraes, Fernando Faria Franco, Gislaine A.R. Silva, Juliana R. Bombonato, Marlon Machado, Diego P. Alonso, Paulo E.M. Ribolla & Dirk C. Albach
Hybridization and introgression between species in contact/hybrid zones provide important insight into the genetic and ecological mechanisms of speciation. Cactaceae represents the most important radiation of true succulent angiosperms in the New World. This diversification continues to date, with species experiencing few intrinsic barriers to gene flow and the frequent occurrence of natural hybridization. Here, we used RAD-Seq single-nucleotide polymorphism (SNP) data to investigate the genetic architecture of hybridization in four hybrid zones hosting Melocactus...

Total Ortholog Median Matrix (TOMM): an alternative unsupervised approach for phylogenomics based on evolutionary distance between protein coding genes

Sandra R. Maruyama, Luana A. Rogerio, Patrícia Domingues Freitas, Marta Maria Teixeira & José Marcos Ribeiro
The increasing number of available genomic data allowed the development of phylogenomic analytical tools. Current methods compile information from single gene phylogenies, whether based on topologies or multiple sequence alignments. Generally, phylogenomic analyses elect gene families or genomic regions to construct phylogenomic trees. Here, we presented an alternative approach for Phylogenomics, named TOMM (Total Ortholog Median Matrix), to construct a representative phylogram composed by amino acid distance measures of all pairwise ortholog protein sequence pairs...

Data from: The relationship between pond habitat depth and functional tadpole diversity in an agricultural landscape

Cássia De Souza Queiroz, Fernando Rodrigues Da Silva & Denise De Cerqueira Rossa-Feres
One of the most important goals of biodiversity studies is to identify which characteristics of local habitats act as filters that determine the diversity of functional traits along environmental gradients. In this study, we investigated the relationship between the environmental variables of ponds and the functional trait diversity distribution of anuran tadpoles in an agricultural area in southeastern Brazil. Our results show that the functional trait diversity of frog tadpoles has a bell-curve-shaped relationship with...

Data from: Environmental gradients and the evolution of successional habitat specialization: a test case with 14 Neotropical forest sites

Susan G. Letcher, Jesse R. Lasky, Robin L. Chazdon, Natalia Norden, S. Joseph Wright, Jorge A. Meave, Eduardo A. 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: Habitat filtering determines the functional niche occupancy of plant communities worldwide

Yuanzhi Li, Bill Shipley, Jodi N. Price, Vinícius De L. Dantas, Riin Tamme, Mark Westoby, Andrew Siefert, Brandon S. Schamp, Marko J. Spasojevic, Vincent Jung, Daniel C. Laughlin, Sarah J. Richardson, Yoann Le Bagousse-Pinguet, Christian Schöb, Antonio Gazol, Honor C. Prentice, Nicolas Gross, Jacob Overton, Marcus V. Cianciaruso, Frédérique Louault, Chiho Kamiyama, Tohru Nakashizuka, Kouki Hikosaka, Takehiro Sasaki, Masatoshi Katabuchi … & Marco A. Batalha
How the patterns of niche occupancy vary from species-poor to species-rich communities is a fundamental question in ecology that has a central bearing on the processes that drive patterns of biodiversity. As species richness increases, habitat filtering should constrain the expansion of total niche volume, while limiting similarity should restrict the degree of niche overlap between species. Here, by explicitly incorporating intraspecific trait variability, we investigate the relationship between functional niche occupancy and species richness...

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...

Differential speciation rates, colonization time, and niche conservatism affect community assembly across adjacent biogeographical regions

Ronildo Benício, Diogo Provete, Mariana Lyra, Jani Heino, Célio Haddad, Denise De C. Rossa-Feres & Fernando Da Silva
Aim: To test the importance of evolutionary and biogeographic processes in shaping the assembly of local frog communities in two adjacent regions (hereafter, coastal and inland regions) with different historical signatures. We asked two main questions: i) why does the coastal region harbor more frog species than the inland region? and ii) how do these processes affect the relationship between the spatial variation of taxonomic, phylogenetic, and functional diversities within and across these regions? Location:...

Data from: Interglacial microrefugia and diversification of a cactus species complex: phylogeography and palaeodistributional reconstructions for Pilosocereus aurisetus and allies

Isabel A. S. Bonatelli, Manolo F. Perez, A. Townsend Peterson, Nigel P. Taylor, Daniela C. Zappi, Marlon C. Machado, Ingrid Koch, Adriana H. C. Pires & Evandro M. Moraes
The role of Pleistocene climate changes in promoting evolutionary diversification in global biota is well documented, but the great majority of data regarding this subject come from North America and Europe, which were greatly affected by glaciation. The effects of Pleistocene changes on cold- and/or dry-adapted species in tropical areas where glaciers were not present remain sparsely investigated. Many such species are restricted to small areas surrounded by unfavourable habitats, which may represent potential interglacial...

Chiarello, Jean-François Cosson, Will Cresswell, Filibus Danjuma Dami, Jens Dauber, Christopher R. Dickman, Raphael K. Didham, David P. Edwards, Fabio Z. Farneda, Yoni Gavish, Thiago Gonçalves-Souza, Demetrio Luis Guadagnin, Mickaël Henry, Adrià López-Baucells, Heike Kappes … & Yaron Ziv
Habitat destruction is the single greatest anthropogenic threat to biodiversity. Decades of research on this issue have led to the accumulation of hundreds of data sets comparing species assemblages in larger, intact, habitats to smaller, more fragmented, habitats. Despite this, little synthesis or consensus has been achieved, primarily because of non‐standardized sampling methodology and analyses of notoriously scale‐dependent response variables (i.e., species richness). To be able to compare and contrast the results of habitat fragmentation...

Data from: Highly conserved Z and molecularly diverged W chromosomes in the fish genus Triportheus (Characiformes, Triportheidae)

C.F. Yano, L.A.C. Bertollo, T. Ezaz, V. Trifonov, A. Sember, T. Liehr & M.B. Cioffi
The main objectives of this study were to test: (1) whether the W-chromosome differentiation matches to species’ evolutionary divergence (phylogenetic concordance) and (2) whether sex chromosomes share a common ancestor within a congeneric group. The monophyletic genus Triportheus (Characiformes, Triportheidae) was the model group for this study. All species in this genus so far analyzed have ZW sex chromosome system, where the Z is always the largest chromosome of the karyotype, whereas the W chromosome...

Data from: Pleistocene niche stability and lineage diversification in the subtropical spider Araneus omnicolor (Araneidae)

Elen A. Peres, Thadeu Sobral-Souza, Manolo F. Perez, Isabel A. S. Bonatelli, Daniel P. Silva, Marcio J. Silva & Vera N. Solferini
The influence of Quaternary climate oscillations on the diversification of the South American fauna is being increasingly explored. However, most of these studies have focused on taxa that are endemic to tropical environments, and relatively few have treated organisms restricted to subtropical biomes. Here we used an integrative phylogeographical framework to investigate the effects of these climate events on the ecological niche and genetic patterns of the subtropical orb-weaver spider Araneus omnicolor (Araneidae). We analyzed...

Data from: The genomes of two key bumblebee species with primitive eusocial organisation

Ben M. Sadd, Seth M. Barribeau, Guy Bloch, Dirk C. De Graaf, Peter Dearden, Christine Elsik, Jurgen Gadau, Cornelius Grimmelikhuijzen, Martin Hasselmann, Jeffrey Lozier, Hugh Robertson, Guy Smagghe, Eckart Stolle, Matthias Van Vaerenbergh, Robert Waterhouse, Erich Bornberg-Bauer, Steffan Klasberg, Anna Bennett, Francisco Camara, Roderic Guigo, Katharina Hoff, Marco Mariotti, Monica Munos-Torres, Terence Murphy, Didac Santesmasses … & Kim C. Worley
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome...

Data from: A new subfamily classification of the Leguminosae based on a taxonomically comprehensive phylogeny

, Anne Bruneau, Nasim Azani, Marielle Babineau, Edeline Gagnon, Carole Sinou, Royce Steeves, Erin Zimmerman, C. Donovan Bailey, Lynsey Kovar, Madhugiri Nageswara-Rao, Hannah Banks, RuthP. Clark, Manuel De La Estrella, Peter Gasson, GeoffreyC. Kite, BenteB. Klitgaard, GwilymP. Lewis, Danilo Neves, Gerhard Prenner, María De Lourdes Rico-Arce, ArianeR. Barbosa, Maria Cristina López-Roberts, Luciano Paganucci De Queiroz, PétalaG. Ribeiro … & Tingshuang Yi
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new classification uses as its framework the most comprehensive phylogenetic analyses of legumes to date, based on plastid matK gene sequences, and including near-complete sampling of genera (698 of the currently recognised 765 genera) and ca. 20% (3696) of known species. The matK gene region has been the most...

Data from: Humidity levels drive reproductive modes and phylogenetic diversity of amphibians in the Brazilian Atlantic Forest

Fernando Rodrigues Silva, Mário Almeida-Neto, Vitor Hugo Mendonça Do Prado, Célio Fernando Baptista Haddad & Denise De Cerqueira Rossa-Feres
AIM: The diversity of reproductive modes among amphibians provides a striking example of how differences in the biology of species furnish can provide important explanations for species distribution patterns on a broad scale. We hypothesized that sites with a higher humidity level will support more different modes of reproduction than drier sites and will consequently exhibit a higher phylogenetic diversity. Furthermore, we predict that if there is a gradient in the tolerance of reproductive modes...

Non-continuous reproductive phenology of animal-dispersed species in young forest restoration plantings

Crislaine De Almeida & Ricardo Augusto Gorne Viani
Tree species that produce resources for fauna are recommended for forest restoration plantings to attract pollinators and seed dispersers; however, information regarding the flowering and fruiting of these species during early growth stages is scarce. We evaluated the reproductive phenology of animal-dispersed tree species widely used in Atlantic Forest restoration. We marked 16 animal-dispersed tree species in 3- to 8-year-old forest restoration plantings in Itu-São Paulo, southeast Brazil. We noted the age of the first...

Background: Noninvasive collection of feces is a cost-effective strategy for monitoring free-living wild mammals. The aim of this study was to search for carnivore and artiodactyl species and investigate the gastrointestinal parasites in their feces, in Itatiaia National Park, Brazil. Methodology/Main Findings: Between 2017 and 2018, feces from carnivores and artiodactyls were collected along trails in the park. Host species were identified from these feces through macroscopic and trichological examination and through molecular biology using...

A new approach to map landscape variation in forest restoration success in tropical and temperate forest biomes

Renato Crouzeilles, Felipe S. M. Barros, Paulo G. Molin, Mariana S. Ferreira, André B. Junqueira, Robin L. Chazdon, David B. Lindenmayer, Julio R. C. Tymus, Bernardo B. N. Strassburg & Pedro H. S. Brancalion
A high level of variation of biodiversity recovery within a landscape during forest restoration presents obstacles to ensure large‐scale, cost‐effective and long‐lasting ecological restoration. There is an urgent need to predict landscape variation in forest restoration success at a global scale. We conducted a meta‐analysis comprising 135 study landscapes to predict and map landscape variation in forest restoration success in tropical and temperate forest biomes. Our analysis was based on the amount of forest cover...

Data from: Model-based analysis supports interglacial refugia over long-dispersal events in the diversification of two South American cactus species

Manolo Perez, Isabel A. S. Bonatelli, Evandro Moraes & Bryan C. Carstens
Pilosocereus machrisii and P. aurisetus are cactus species within the P. aurisetus complex, a group of eight cacti that are restricted to rocky habitats within the Neotropical savannas of eastern South America. Previous studies have suggested that diversification within this complex was driven by distributional fragmentation, isolation leading to allopatric differentiation, and secondary contact among divergent lineages. These events have been associated with Quaternary climatic cycles, leading to the hypothesis that the xerophytic vegetation patches...

Data from: Fire-sensitive species dominate seed rain in a long unburned Cerrado: implications for plant community diversity and woody encroachment in savannas

Vanessa Mariano, Isabele F. Rebolo & Alexander V. Christianini.
Woody encroachment is becoming common in tropical savannas. Seed rain data and seed addition experiments in a long unburned Brazilian savanna indicate that abundant seed rain of fire-sensitive species can surpass limitations to recruitment and lead to woody encroachment. Thus, active fire management may be required to maintain savanna diversity.

Data from: Convergence of soil nitrogen isotopes across global climate gradients

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...

RAD-seq data from: Evidence of local adaptation despite strong drift in a Neotropical patchily distributed bromeliad

Bárbara Simões Santos Leal, Cleber Juliano Neves Chaves, Vanessa Araujo Graciano, Christophe Boury, Luis Alberto Pillaca Huacre, Myriam Heuertz & Clarisse Palma-Silva
Both genetic drift and divergent selection are predicted to be drivers of population differentiation across patchy habitats, but the extent to which these forces act on natural populations to shape traits is strongly affected by species' ecological features. In this study, we infer the genomic structure of Pitcairnia lanuginosa, a widespread herbaceous perennial plant with a patchy distribution. We sampled populations in the Brazilian Cerrado and the Central Andean Yungas and discovered and genotyped SNP...

Data from: Conservation genetics of Neotropical pollinators revisited: microsatellite analysis suggests that diploid males are rare in orchid bees

Rogério Souza, Marco Del Lama, Marcelo Cervini, Norma Mortari, Thomas Eltz, Yvonne Zimmermann, Carola Bach, Berry Brosi, Sevan Suni, Javier Quezada & Robert Paxton
Allozyme analyses have suggested that Neotropical orchid bee (Euglossini) pollinators are vulnerable because of putative high frequencies of diploid males, a result of loss of sex allele diversity in small hymenopteran populations with single locus complementary sex determination. Our analysis of 1010 males from 27 species of euglossine bees sampled across the Neotropics at 2-11 polymorphic microsatellite loci revealed only 5 diploid males at an overall frequency of 0.005 (95% CIs 0.002-0.010); errors through genetic...

Data from: Genetic variation in blue whales in the eastern Pacific: implication for taxonomy and use of common wintering grounds

Richard G. LeDuc, F.I. Archer, Aimee R. Lang, Karen K. Martien, Brittany Hancock-Hanser, Juan P. Torres-Florez, Rodrigo Hucke-Gaete, Howard C. Rosenbaum, Koen Van Waerebeek, Robert L. Brownell, Barbara L. Taylor & F. I. Archer
Many aspects of blue whale biology are poorly understood. Some of the gaps in our knowledge, such as those regarding their basic taxonomy and seasonal movements, directly affect our ability to monitor and manage blue whale populations. As a step towards filling in some of these gaps, microsatellite and mtDNA sequence analyses were conducted on blue whale samples from the Southern Hemisphere, the eastern tropical Pacific (ETP), and the northeast Pacific. The results indicate that...
