    O crescimento desordenado das cidades tem gerado impactos ao meio ambiente e a infraestrutura urbana. O crescimento da impermeabilização do solo vem causando aumento das enxurradas e consequentemente o número de enchentes urbanas. O objetivo deste artigo é apresentar uma revisão bibliográfica, bem como os materiais empregados e técnicas de execução. Sanando dúvidas através do estudo de caso. O centro desse estudo é demonstrar, a implantação da rede de drenagem profunda na Avenida Tancredo Neves – Parque Dez, visando melhorias aos moradores e comerciantes da referida região. Ainda na fase de análise foram levantados junto a prefeitura do município os dados sobre as galerias pluviais. Esses dados serviram de subsídio para os cálculos de dimensionamento onde foram mantidos os diâmetros existentes e verificados se os trechos de galerias respeitavam os parâmetros exigidos pela norma. Já as galerias apresentaram trechos com alta velocidade e foi necessário redimensioná-las com alteração dos diâmetros nos pontos com problemas

    SITUAÇÃO DE ESTUDO: O RIO CARIMÃ DA CIDADE DOS BARREIROS NO CONTEXTO SOCIOCULTURAL E AMBIENTAL

    Este trabalho descreve uma experiência Interdisciplinar desenvolvida e vivenciada por professores e alunos do Ensino Médio. A situação de estudo apresentada pelos professores foi “O rio Carimã”, a qual foi estudada por meio da situação-problema: O que acontece quando jogamos lixo e resíduos no rio Carimã? Nesse contexto, a temática foi explorada de forma contextualizada e interdisciplinar. A intervenção interdisciplinar proposta permitiu o desenvolvimento de atividades experimentais, favorecendo a integração de conteúdos da biologia, da física e da química. Sob a ótica dessas disciplinas procurou-se resolver a situação-problema. Visita as margens do rio, exibição de vídeo e pesquisas em fontes variadas (livros didáticos, revistas, periódicos, internet, etc.) contribuíram para construção de conceitos e aprendizagem significativa.  Palavras-chave: interdisciplinaridade, rio Carimã, situação de estudo

    NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

    Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set. Please cite this data paper when using its data in publications. We also request that researchers and teachers inform us of how they are using these data

    NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

    No full text
    Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used.
