Abstract. Measures of traits are the basis of functional biological diversity. Numerous works consider mean species-level measures of traits while ignoring individual variance within species. However, there is a large amount of variation within species and it is increasingly apparent that it is important to consider trait variation not only between species, but also within species. Mammals are an interesting group for investigating trait-based approaches because they play diverse and important ecological functions (e.g., pollination, seed dispersal, predation, grazing) that are correlated with functional traits. Here we compile a data set comprising morphological and life history information of 279 mammal species from 39,850 individuals of 388 populations ranging from À5.83 to À29.75 decimal degrees of latitude and À34.82 to À56.73 decimal degrees of longitude in the Atlantic forest of South America. We present trait information from 16,840 individuals of 181 species of non-volant mammals (Rodentia, Didelphimorphia, Carnivora, Primates, Cingulata, Artiodactyla, Pilosa, Lagomorpha, Perissodactyla) and from 23,010 individuals of 98 species of volant mammals (Chiroptera). The traits reported include body mass, age, sex, reproductive stage, as well as the geographic coordinates of sampling for all taxa. Moreover, we gathered information on forearm length for bats and body length and tail length for rodents and marsupials. No copyright restrictions are associated with the use of this data set.

The native marmoset of the Southeastern Atlantic Forest in Brazil is among the 25 most endangered primates of the world. Hybridization with alien species is one of its main threats registered since the early 2000s based on phenotype, so far, without genetic confirmation. Using uniparental molecular markers, we analyzed 18 putative hybrids, captured from 2004 to 2013 in different localities of the Atlantic Forest. A nine base pair deletion in the SRY gene of C. aurita was used to investigate paternal ancestry. Maternal ancestry was assessed by DNA sequencing of ca. 455 bp from the COX2 gene. Hybridization was confirmed for 16 out of the 18 marmosets since they inherited COX2 haplotypes of the alien C. penicillata or C. jacchus and the SRY deletion specific to C. aurita. Two individuals inherited both parental lineages of C. aurita, which is probably related to backcrossing or hybrid interbreeding. The direction of hybridization of females with the matrilineal lineage of invasive species with males descending from the native lineage was predominant in our sampling. This is the first time that hybridization between C. aurita and invasive species has been confirmed through genetic analysis.
Introdução: A doença do novo coronavírus (COVID-19) foi responsável pela ocorrência de alterações na coagulação, facilitando a incidência de trombose venosa profunda, especialmente na unidade de terapia intensiva. Objetivo: Descrever a incidência da Trombose Venosa Profunda nos pacientes diagnosticados com COVID-19. O objetivo secundário foi analisar as principais complicações em decorrência da associação entre COVID-19 e trombose venosa profunda. Metodologia: Estudo observacional, retrospetivo, realizado entre fevereiro e maio de 2021. Na análise estatística, utilizou-se o teste U de Mann-Whitney para variáveis quantitativas, o teste exato de Fischer para avaliar variáveis qualitativas nominais e a análise multivariada para avaliar as variáveis associadas à Trombose Venosa Profunda. Resultados: A pesquisa avaliou 26 pacientes com idade média de 54 anos (47,0 - 63,0) e 69,2% do sexo masculino. A trombose venosa profunda esteve presente em 62% dos pacientes e houve diferença significativa com maior tempo de internação (p-valor 0,007), cerca de 63% apresentaram trombocitopenia, 37,5% necessitaram de hemodiálise e 31,3% morreram. Conclusão: Observou-se alta incidência da trombose venosa profunda nos pacientes graves com COVID-19 na unidade de terapia intensiva. A trombocitopenia foi identificada como um preditor para a ocorrência da trombose venosa profunda. A associação da COVID-19 e trombose venosa profunda causou impacto significativo no quadro clínico durante a hospitalização, através da identificação do longo período de internação, oxigenoterapia com ventilação mecânica, lesão renal aguda com necessidade de hemodiálise e taxa de mortalidade entre eles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
