ABSTRACT The Design of the Visual Communication of the software contributes to a better use, satisfaction and acceptance of the user with the computer applications. Due to its impact on Usability, organizations producing business management software should consider as part of their quality management, the evaluation of Visual Communication Design. This contributes to making the products more efficient and effective in their use and message to be communicated, both in the graphic interfaces and in the technical support means. The objective of this work is to share the development and validation of an instrument that deepens the assessment of Usability, by evaluating the quality of the Visual Communication Design of business management software. The main methods and techniques used were documentary analysis for the study of authors and national and international standards. The participant observation, for the evaluation process of the business management software and the interview to evaluators of said products. The Delphi method, to collect expert judgment on the instrument.

RESUMEN El Diseño de la Comunicación Visual del software aporta a un mejor empleo, satisfacción y aceptación del usuario con las aplicaciones informáticas. Por su impacto en la Usabilidad, las organizaciones productoras de software de gestión empresarial debieran contemplar como parte de su gestión de calidad, la evaluación del Diseño de la Comunicación Visual. Ello contribuye a que los productos sean más eficientes y eficaces en su uso y mensaje a comunicar, tanto en las interfaces gráficas como en los medios de apoyo técnico. El presente trabajo tiene como objetivo compartir la elaboración y validación de un instrumento que profundiza en la valoración de la Usabilidad, mediante la evaluación de la calidad del Diseño de Comunicación Visual del software de gestión empresarial. Los principales métodos y técnicas empleados fueron, el análisis documental, para el estudio de autores y normas nacionales e internacionales. La observación participante, para el proceso de evaluación del software de gestión empresarial y la entrevista a evaluadores de dichos productos. El método Delphi, para recopilar criterios de expertos sobre el instrumento.

Islands can serve as model systems for understanding how biological invasions affect native species. Here we examine the negative effects of mesopredator mammals on bird richness at Anchieta Island, an 826 ha offshore island in the coast of Brazil. Anchieta Island has the highest density of mammals of the entire Atlantic forest, especially nest predators such as marmosets and coatis, introduced more than 20 years ago. This indiscriminate introduction of mammals may have affected directly the bird community, nowadays represented by 100 species comprised mainly by water-crossing birds, being 73 forest-dwelling species. A small component of these remnant bird species nests in tree holes and on the forest floor, null model analysis suggest that birds within these two nest types are under-represented on Anchieta Island. All guilds were affected negatively, but "opportunist insectivorous/omnivorous". Experiments using artificial nests showed a predation of 73% of nests on the floor while only 26% on the mainland. Camera traps recorded predation by coatis, agoutis, and opossums. The restoration of the bird community on this island is highly constrained by the high density of hyper abundant nest predators.

Experimentos com ninhos artificiais são utilizados para testar hipóteses ecológicas e comportamentais que influenciam na predação de ninhos naturais. O tamanho do ovo, a textura da casca e a cor podem influenciar na taxa de predação, porém poucos estudos avaliam qual modelo de ovo é o mais adequado para simular a predação de ninhos em áreas tropicais. O objetivo deste trabalho foi comparar a predação de diferentes modelos de ovos (ovos de codorna, massa de modelar e canários) no solo e a 1,30 m de altura no sub-bosque. O experimento foi realizado Ilha Anchieta, Ubatuba, São Paulo, Brasil. Foi encontrada uma diferença significativa na taxa de predação entre os ovos de codorna (71,87%) e sintéticos (93,75%) e entre os ovos de codorna e de canário (100%) no solo. Entretanto, não houve diferença significativa entre os ovos sintéticos e de canário. Os ninhos no sub-bosque apresentaram um padrão diferenciado do solo quando se refere aos ovos de codorna (25%) e sintéticos (28,1%), mas houve diferenças significativas quando os ovos de canário foram comparados com os ovos sintéticos e de codorna. Nosso trabalho demonstrou que diferentes tipos de ovos sobre uma mesma pressão de mesopredadores apresentaram taxas de predação diferentes. Portanto, estudos que avaliam o sucesso reprodutivo da avifauna baseado na predação de ninhos artificiais devem considerar a utilização de diferentes tipos de ovos e estratos na vegetação.

Experiments on artificial nests are usually used to test ecological hypothesis and behavioural that affects the predation of natural bird nests. It is has been discussed about the size of the egg, texture and color affecting predation rate, but a few studies evaluate which egg type is more appropriate to simulate nest predation in tropical areas. The objective of this work was to compare the predation of different models of eggs (Coturnix coturnix, plasticine and Serinus canarius) on the ground and understory in a island with high abundance of nest predators. The study was carry out in October 2004 at Anchieta Island, Ubatuba, São Paulo, Brazil. The nests on the ground showed a statistical significance difference in the predation of quail eggs, plasticine and canary eggs. However, we did not find differences between plasticine and canaries eggs. The nests in the understory had a different pattern on the ground of quail eggs (25%) and plasticine (28%) and there was a difference when we compare canary eggs with plasticine and quail eggs. Our work pointed out that different eggs may have different predation rates. Therefore, studies that evaluate reproductive fitness of the bird community based on artificial nests must considered different egg types and strata.
