Polymorphic microsatellite DNA markers for the Amazonian catfish Pseudoplatystoma punctifer (Siluriformes: Pimelodidae)

The large catfish Pseudoplatystoma punctifer has a high commercial value in the Amazon. Fifteen polymorphic microsatellite loci were isolated and characterized in 36-39 individuals of this species sampled at the Purus river (Amazon Basin). The number of alleles per locus ranged from 2 to 18 (average 7.4), the observed heterozygosity (H O) from 0.025 to 0.972 and the expected heterozygosity (H E) from 0.025 to 0.931. Two loci showed a Hardy-Weinberg Equilibrium deviation. No linkage disequilibrium was found among the studied loci. Fourteen microsatellite loci were cross-amplified successfully in six other Pimelodidae species. Therefore, these loci may be valuable for other studies of population genetic structure as well as for catfish conservation in the Amazon basin. © Springer Science+Business Media B.V. 2010

Implementação da Metodologia 5’S num Setor de Manutenção de uma Indústria Cerâmica

A necessidade de qualquer empresa se adaptar às condições de mercado constitui uma constante e, se adicionarmos o fator globalização, torna-se um imperativo. Face a esta situação, são muitas as empresas que começam a abandonar os métodos de gestão, ditos “tradicionais”, e começam a perseguir novas metodologias, com destaque para o Lean Manufacturing. Neste contexto, assumindo-se como uma das ferramentas elementares da filosofia Lean, a Metodologia 5’S apresenta como primordial objetivo a eliminação do “desperdício”, em paralelo com a criação de um ambiente de trabalho mais organizado, limpo e seguro, contribuindo desta forma, para a otimização dos processos operacionais de uma empresa. A origem do termo “5’S”, fica a dever-se à letra inicial “S” de cinco palavras japonesas que dão o nome a cada uma das etapas da própria metodologia. São elas: Seiri (Classificação e Separação), Seiton (Organização), Seiso (Limpeza), Seiketsu (Estandardização), Shitsuke (Autodisciplina). Neste trabalho, será analisada a capacidade da metodologia 5’S em eliminar o desperdício numa empresa do setor cerâmico tomada como referência, bem como a eficácia da mesma, no estabelecimento de um local de trabalho mais eficiente, confortável, e seguro para os trabalhadores.ABSTRACT: The companies must adapt to business requirements constantly, mainly if the Globalization would be considered as factor. That is why so many companies are starting to follow the Lean Manufacturing philosophy instead of Management traditional methods. Based on this scenario, the main purpose of 5S methodology, classified as one of the most important lean manufacturing tools, is eliminate wasting while provide the work environment clean, organized and safe, in that way, providing operational process improvements. The origin of 5S is regarding to initial letter "s" of five Japanese words which represents every single step of the methodology, which are: Seiri (Classification and Split), Seiton (Organization), Seiso (Cleaning), Seiketsu (Standard) and Shitsuke (Selfdiscipline). During this project, it is going to be analyzed how the 5S methodology can affect in the wasting elimination in a ceramic company taken as a reference, and its efficiency as well to stablish one work environment more efficient, comfortable and safe for employees

Biodiversidad en la cuenca del Orinoco. Bases científicas para la identificación de áreas prioritarias para la conservación y uso sostenible de la biodiversidad

Es un placer para el Instituto de Investigación de Recursos Biológicos Alexander von Humboldt presentar a la comunidad científica, conservacionista y autoridades ambientales de Colombia y Venezuela la obra Biodiversidad de la cuenca del Orinoco: bases científicas para la identificación de áreas prioritarias para la conservación y el uso sostenible de la biodiversidad. Este libro es fruto de un esfuerzo de una década de trabajo y recoge numerosos proyectos de carácter institucional que han venido desarrollándose en la Orinoquia, incluyendo el Plan de acción en biodiversidad para la cuenca del Orinoco (2005-2015), además de los resultados de reuniones técnicas de carácter binacional

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. We also request that users inform us of how they intend to use the data
