Total Ortholog Median Matrix (TOMM): an alternative unsupervised approach for phylogenomics based on evolutionary distance between protein coding genesSandra 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: Historical demography and climate driven distributional changes in a widespread Neotropical freshwater species with high economic importanceManolo 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...
A Intervenção Precoce (IP) é uma importante ferramenta para prevenção, identificação e intervenção junto às condições que oferecem riscos ao desenvolvimento infantil. Nesse sentido, uma série de recomendações têm sido feitas com vistas ao desenvolvimento das melhores práticas. No entanto, ainda não se pode afirmar que as ações sejam desenvolvidas de uma forma homogênea pelos diferentes países que utilizam esse recurso, o que justifica o investimento na elucidação dos cenários para o melhor direcionamento dos...
Non-continuous reproductive phenology of animal-dispersed species in young forest restoration plantingsCrislaine 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...
Noninvasive fecal sampling in Itatiaia National Park, Brazil: wild mammal identification and parasite detectionLais Dib, Joao Pedro Palmer, Camila Lima, Jessica Pinheiro, Raissa Cristina Ramos, Claudijane Santos, Ana Beatriz Fonsceca, Karen Rodriguez-Castro, Camila Gonçalves, Pedro Galetti, Lais Correa, Otilio Bastos, Claudia Uchoa, Augusto Bastos, Maria Regina Amendoeira & Alynne Barbosa
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...
Data from: Savannas after afforestation: assessment of herbaceous community responses to wildfire versus native tree plantingThaís M. Haddad, Ricardo A. G. Viani, Mário G. B. Cava, Giselda Durigan & Joseph V. Veldman
Afforestation and fire exclusion are pervasive threats to tropical savannas. In Brazil, laws limiting prescribed burning hinder the study of fire in the restoration of Cerrado plant communities. We took advantage of a 2017 wildfire to evaluate the potential for tree cutting and fire to promote the passive restoration of savanna herbaceous plant communities after destruction by exotic tree plantations. We sampled a burned pine plantation (Burned Plantation); a former plantation that was harvested and...
Precambrian filamentous microfossils are common and diverse. Nevertheless, their taxonomic assignment can be difficult due to their overall simple shapes typically lacking in diagnostic features. Here, we report in situ communities of well-preserved, large filamentous impressions from the Ediacaran Itajaí Basin (ca. 563 Ma) of Brazil. The filaments are uniserial (unbranched) and can reach up to 200 µm in width and up to 44 mm in length. They occur as both densely packed or sparsely...
