A scoping study of pulmonary paracoccidioidomycosis: severity classification based on radiographic and tomographic evaluation

Sergio Marrone Ribeiro, Thiago Franchi Nunes, Ricardo de Souza Cavalcante, Anamaria Mello Miranda Paniago, Beatriz Aparecida Soares Pereira & Rinaldo Poncio Mendes
Abstract The lungs have great importance in patients with paracoccidioidomycosis since they are the portal of entry for the infecting fungi, the site of quiescent foci, and one of the most frequently affected organs. Although they have been the subject of many studies with different approaches, the severity classification of the pulmonary involvement, using imaging procedures, has not been carried out yet. This study aimed to classify the active and the residual pulmonary damage using...

Data from: Chewing on the trees: constraints and adaptation in the evolution of the primate mandible

Carlo Meloro, Nilton Carlos Cáceres, Francesco Carotenuto, Jonas Sponchiado, Geruza Leal Melo, Federico Passaro & Pasquale Raia
Chewing on different food types is a demanding biological function. The classic assumption in studying the shape of feeding apparatuses is that animals are what they eat, meaning that adaptation to different food items accounts for most of their interspecific variation. Yet, a growing body of evidence points against this concept. We use the primate mandible as a model structure to investigate the complex interplay between shape, size, diet and phylogeny. We find a weak...

Between June 2017 and August 2018, several municipalities located in Bahia state (Brazil) reported a large increase in the number of patients presenting with febrile illness similar to that of arboviral infections. Using a combination of portable whole genome sequencing, molecular clock and epidemiological analyses, we revealed the return of the CHIKV-ECSA genotype into Bahia. Our results show local persistence of lineages in some municipalities and the re-introduction of new epidemiological strains from different Brazilian...

River dams and the stability of bird communities: A hierarchical Bayesian analysis in a tropical hydroelectric power plant

Tarcísio Abreu, Sandro Berg, Iubatã Faria, Leonardo Gomes, Jader Marinho-Filho & Guarino Colli
The effects of anthropogenic disturbance upon the stability of wildlife communities depend on the heterogeneity and connectivity of habitat remnants on multiple scales. The number of hydroelectric dams in biodiversity hotspots (Africa, South America and Asia) is growing rapidly. To establish their environmental impact, it is essential to understand the dynamics of wildlife communities before and following the establishment of dams. We evaluated the impacts of the filling of the Serra do Facão hydroelectric reservoir...

Data from: Architectural constraints, male fertility variation and biased floral morph ratios in tristylous populations

Nicolay L. Da Cunha & Spencer C. H. Barrett
Tristyly is a genetic polymorphism in which populations are comprised of three floral morphs (mating types) differing reciprocally in sex-organ height. Intermorph (disassortative) mating governed by a trimorphic incompatibility system should result in 1:1:1 morph ratio at equilibrium, but both deterministic and stochastic processes can cause skewed morph ratios in tristylous populations. Here, we investigate mechanisms causing morph-ratio bias in Pontederia parviflora, an emergent aquatic native to tropical America. We compared reproductive traits among morphs...

Abundance data of anuran species in forest fragments

M Almeida-Gomes, NJ Gotelli, CFD Rocha, MV Vieira & JA Prevedello
Understanding the effects of random versus niche-based processes on biodiversity patterns is a central theme in ecology, and an important tool for predicting effects of habitat loss and fragmentation on biodiversity. We investigated the predictive power of random processes to explain species richness and species dissimilarity of amphibian assemblages in a fragmented tropical landscape of the Atlantic Forest of South America. We analyzed a large database of amphibian abundance and occupancy, sampled in 21 forest...

ABSTRACT This study examined the effect of different supplementation strategies for ewes in the last third of gestation, kept on a deferred Brachiaria brizantha cv. Marandu pasture, on their performance and the growth curve of their lambs. A total of 54 ewes, of no defined breed, with an average weight of 41.10±3.10 kg, were used in a completely randomized design, divided into three groups (18 ewes per treatment). In total, 61 lambs were born, 28...

Giant Reed (Arundo donax L.) Fiber Extraction and Characterization for Its Use in Polymer Composites

Luis Suárez, Mateusz Barczewski, Paulina Kosmela, María D. Marrero & Zaida Ortega
This work describes an extraction method for giant reed fibers from stems and leaves based on chemical soaking and crushing through a rolling mill. Obtained fibers, together with the shredded plant (stems + leaves), are characterized in terms of chemical composition, thermal stability, morphology, and crystallinity. Mechanical properties of fibers have also been assessed (single fiber tensile tests). The results show that the proposed method allows obtaining fibers with higher cellulose content (near 70%), good...

Machado, Maria A. Maglianesi, Tiago S. Malucelli, Ana M. Martín-González, Genilda M. Oliveira, Paulo E. Oliveira, Raul Ortiz-Pulido, Márcia A. Rocca, Licléia C. Rodrigues, Ivan Sazima, Benno I. Simmons, Boris Tinoco, Isabela G. Varassin, Marcelo F. Vasconcelos, Bob O’Hara … & Bo Dalsgaard
Interactions between species are influenced by different ecological mechanisms, such as morphological matching, phenological overlap, and species abundances. How these mechanisms explain interaction frequencies across environmental gradients remains poorly understood. Consequently, we also know little about the mechanisms that drive the geographical patterns in network structure, such as complementary specialization and modularity. Here, we use data on morphologies, phenologies and abundances to explain interaction frequencies between hummingbirds and plants at a large geographic scale. For...

Allometric escape from acoustic constraints in frog calls is rare

Joao Filipe Tonini, Diogo Provete, Natan Maciel, Alessandro Morais, Sandra Goutte, Felipe Toledo & R. Alexander Pyron
Allometric constraint is a product of natural selection, particularly with respect to body size and traits constrained by physical properties thereof, such as metabolism, longevity, and vocal frequency. Parameters describing allometric relationships are conserved across most lineages, indicating that physical constraints dictate scaling patterns in deep time, despite substantial genetic and ecological divergence among organisms. Acoustic allometry (sound frequency ~ body size) is conserved across frogs, in defiance of massive variation in both body size...
