    Foot and mouth disease (FMD) is a highly infectious disease that affects cloven-hoofed livestock and wildlife. FMD has been a problem for decades, which has led to various measures to control, eradicate and prevent FMD by National Veterinary Services worldwide. Currently, the identification of areas that are at risk of FMD virus incursion and spread is a priority for FMD target surveillance after FMD is eradicated from a given country or region. In our study, a knowledge-driven spatial model was built to identify risk areas for FMD occurrence and to evaluate FMD surveillance performance in Rio Grande do Sul state,...

    Being taller is associated with enhanced longevity, and higher education and earnings. We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.5–22.7) and 16.5 cm (13.3– 19.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest...

  9. Using ancient DNA to unravel taxonomic puzzles : the identity of Deuterodon pedri (Ostariophysi: Characidae)

    Silva, Priscilla Caroline; Malabarba, Maria Claudia de Souza Lima; Malabarba, Luiz Roberto
    Accurate identification is essential for any study exploring biodiversity. Unfortunately, museum type specimens preserved for more than a hundred years are often not informative enough for precise identification of the species represented by the name-bearing type. The use of ancient DNA can help solve taxonomic problems when name-bearing types no longer have diagnostic morphological features that allow for an accurate identification of the species involved. That is the case for Deuterodon pedri, an endemic species from a small drainage in the rio Doce basin in Minas Gerais, Brazil, for which the type material is in poor condition. Specimens of D....

  12. Structure of the tree stratum of three swamp forest communities in southern Brazil under different soil conditions

    Mancino, Luciana Carla; Overbeck, Gerhard Ernst; Baptista, Luis Rios de Moura
    Restinga forests are commonly known to be plant communities rather poor in tree species. This study aimed to describe and explain the association between the floristic-structural similarities and the environmental conditions in three Swamp Restinga Forest communities in southern Brazil. In 13 plots of 100 m2 each, we sampled all individual trees (circumference at breast height >12 cm and height ≥3 m). We collected soil samples in each plot for chemical and textural analyses. Phytosociological parameters were calculated and different structural variables were compared between areas. The density of individuals did not differ between areas; however, the maximum height and...

  16. Re-evaluation of the generic status of Athenaea and Aureliana (Withaniinae, Solanaceae) based on molecular phylogeny and morphology of the calyx

    Zamberlan, Priscilla Mena; Rodrigues, Izabela M. C.; Mader, Geraldo; Castro, Luana; Stehmann, Joao Renato; Bonatto, Sandro Luis; Freitas, Loreta Brandao de
    Subtribe Withaniinae (Solanaceae) comprises seven genera and c. 40 species, with an almost cosmopolitan distribution. Athenaea and Aureliana are exclusively South American, with diversity centres in the Brazilian Atlantic Rainforest. The generic status of Athenaea and Aureliana was investigated using molecular phylogenetic analysis of five plastid regions (ndhF gene, trnL intron and trnL-trnF, psaI-accD and trnC-ycf6 intergenic spacers), nuclear internal transcribed spacers (ITS) and morphometric analysis of the calyx. Divergence time estimates were also performed. Withaniinae was recovered as monophyletic. The diversification time estimated for Withaniinae was 6.3 Myr, and the estimated diversification time for the Athenaea and Aureliana clades...

  20. Diversity and composition of tiger moths (Lepidoptera: Arctiidae) in an area of Atlantic Forest in southern Brazil : is the fauna more diverse in the grassland or in the forest?

    Ferro, Viviane Gianluppi; Romanowski, Helena Piccoli
    The Atlantic Forest is considered a biodiversity hotspot for conservation, because its fauna and flora are highly endemic and suffer from loss of natural habitats. This study assessed the composition and diversity of tiger moths (Lepidoptera: Arctiidae) in two floristic formations of the southern Atlantic Forest (grassland and Araucaria forest) and in a transition zone (forest edge). The moths were attracted to UV light reflected onto a white sheet. A total of 3,574 tiger moths were collected, representing 121 species. The rarefaction curves showed that the tiger-moth assemblage collected in the grassland was more diverse than the assemblages from the...
