Influência de diferentes populações de plantas e da adubação no sistema consorciado milho e feijão

A field experiment involving monocultures of common bean (Phaseolus vulgaris L.) and maize (Zea mays L.) and the association of these crops was carried out at the Escola Superior de Agricultura de Lavras, Minas Gerais State, Brazil, during the agricultural year 1982/83 with the principal objective of studying the effect of different populations of bean, fertilized and nonfertilized in two systems of cultivation, and their effects on maize an bean. The experimental desing used was randomized blocks in a 5 x 2 factorial, consisting of treatments: five populations of common bean planted between the rows of maize, both fertilized and non-fertilized, with four additional treatment for common bean and three for maize and four replications. It was verified that the production of common bean, when associated, was a direct function of the planting system and the fertilization. The presence of common bean independent of the populations studied and of the presence of fertilizers, did not affect the maize, the production of common bean in association thereby constituting an advantage in economic terms. The results obtained also indicated the necessity of determining the optimum level of fertilization for the mayze-bean association.Um experimento de campo envolvendo os monocultivos do feijão (Phaseolus vulgaris L.) e milho (Zea mays L.) e o consórcio destas culturas, foi conduzido na Escola Superior de Agricultura de Lavras (MG), durante o ano agrícola 1982/83. Tendo como principal objetivo estudar o efeito de diferentes populações de feijoeiro, adubadas e não adubadas, em dois sistemas de cultivo, e seus efeitos sobre o milho e o feijão. O delineamento experimental utilizado foi o de blocos ao acaso, em esquema fatorial 5 x 2, compreendendo os tratamentos: cinco populações de feijoeiro plantado na entrelinha do milho, adubadas e não adubadas, com quatro tratamentos adicionais para o feijão, e três para o milho, com quatro repetições. Verificou-se que a produção do feijoeiro, quando consorciado, foi função direta da população de plantas e da presença da adubação. A presença do feijoeiro, independentemente das populações estudadas e da presença da adubação, não afetou o milho, podendo a produção do feijão no consórcio constituir uma vantagem em termos econômicos. Os resultados obtidos indicam também a necessidade de se determinar um nível ótimo de adubação para o consórcio milho- feijão

As implicações clínicas da doença pulmonar obstrutiva crônica: uma abordagem semiológica / Clinical implications of chronic obstructive pulmonary disease: a semiological approach

O trabalho aqui realizado visa analisar e realizar uma abordagem no âmbito semiológico acerca da “Doença Pulmonar Crônica Obstrutiva”. A patologia em questão acomete centenas de brasileiros e, por vezes, não é diagnosticada precocemente ou tratada de maneira correta. Os sintomas surgem de maneira gradual e lenta, e sua evolução pode ser incapacitante em graves casos de dispneia aos pequenos esforços, por exemplo. É de grande importância que o médico saiba encontrar os padrões de um paciente acometido pela DPOC, pois as evidências apresentadas na clínica são sinais valiosos na semiologia médica. Sabe-se que a principal etiologia que permeia a doença pulmonar obstrutiva crônica é o tabagismo, extremamente popular entre a população nacional e um grande vilão da saúde pública há décadas. Ademais, outros fatores de risco para a doença são: a poluição, agentes químicos, exposição a poeira, inalação de pesticidas em grandes doses, estresse oxidativo e etc. O trabalho em exposição demonstra as diferentes apresentações clínicas e abordagens que podem ser discutidas nessa patologia e a importância de realizar uma procura cautelosa por pacientes acometidos e tratá-los da melhor maneira para um prognóstico satisfatório, já que a doença crônica abordada é a terceira causa de morte entre as doenças crônicas não transmissíveis no Brasil

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

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.

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.
