    Objective: This writing aims to introduce new antimicrobial test apparatus called Canal Dish (CD), theoretically.Methods: We have designed two types of CD such as Circular CD (CCD) and Square CD (SCD). Internally, the CCD is a 80 mm diameter circular while the SCD is a 80√É‚ÄĒ80 mm square CD plate. Both of them contain 2(40√É‚ÄĒ2) mm parallel travelling canals from the each CD-centre having radius of 3 mm. Canals are 6 mm in depth.Results: The features of CCD and SCD indicate possible allowance of various size, low media consuming, the inclusion of multiple microorganisms and/or test samples/doses, ease of handling; therefore, understanding, rapidity, and economy.Conclusion: CD may replace currently used Petri dishes due to its cost-effectiveness, rapidity, ease of handling and a wider range of applicability.Keywords: Antimicrobial assay, Canal dish, Circular, Square, New apparatu

    O trabalho tem como objetivo principal verificar o sistema de rela√ß√Ķes dos criadores de Til√°pia, nos estados do Piau√≠ e do Cear√°, com rela√ß√£o √† Teoria Vision√°ria de Filion (1991). Tendo os seguintes objetivos espec√≠ficos: identificar as vis√Ķes de neg√≥cios dos criadores de Til√°pia; verificar a import√Ęncia dos relacionamentos dos empres√°rios destas empresas para seus empreendimentos. Trata-se de um estudo de caso com piscicultores da Til√°pia nas cidades de Parna√≠ba-PI e Nova Jaguaribara-Ce, usando entrevistas para an√°lise de conte√ļdo. Praticamente em todos os n√≠veis (da fam√≠lia, das rela√ß√Ķes internas e externas) os entrevistados demonstraram que la√ßos familiares facilitam os neg√≥cios

    NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

    No full text
    Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
