Low levels of fruit nitrogen as drivers for the evolution of Madagascar's primate communities

The uneven representation of frugivorous mammals and birds across tropical regions – high in the New World, low in Madagascar and intermediate in Africa and Asia – represents a long-standing enigma in ecology. Several hypotheses have been proposed to explain these differences but the ultimate drivers remain unclear. Here, we tested the hypothesis that fruits in Madagascar contain insufficient nitrogen to meet primate metabolic requirements, thus constraining the evolution of frugivory. We performed a global analysis of nitrogen in fruits consumed by primates, as collated from 79 studies. Our results showed that average frugivory among lemur communities was lower compared to New World and Asian-African primate communities. Fruits in Madagascar contain lower average nitrogen than those in the New World and Old World. Nitrogen content in the overall diets of primate species did not differ significantly between major taxonomic radiations. There is no relationship between fruit protein and the degree of frugivory among primates either globally or within regions, with the exception of Madagascar. This suggests that low protein availability in fruits influences current lemur communities to select for protein from other sources, whereas in the New World and Old World other factors are more significant in shaping primate communities

LWA 2006 Personal Reader Agent: Personalized Access to Configurable Web Services

The Personal Reader Framework enables the design, realization and maintenance of personalized Web Content Reader. In this architecture personalized access to web content is realized by various Web Services- we call them Personalization Services. With our new approach of Configurable Web Services we allow users to configure these Personalization Services. Such configurations can be stored and reused at a later time. The interface between Users and Configurable Web Services is realized in a Personal Reader Agent. This Agent allows selection, configuration and calling of the Web Services and further provides personalization functionalities like reuse of stored configurations which suit the users interests

Métodos de adaptação transcultural de instrumentos na área da enfermagem

Resumo OBJETIVO Identificar os métodos de adaptação transcultural de instrumentos mais utilizados na área da enfermagem. MÉTODOS Revisão integrativa, em fontes eletrônicas Medline via Pubmed, Cinahl, Lilacs, Scopus e Web of Science. Foram selecionados 96 artigos revisados por pares e publicados entre 2010 e 2015. RESULTADOS Os artigos que compuseram a amostra foram publicados em 59 periódicos diferentes, sendo 15,2% destes brasileiros. O maior número de publicações concentrou-se em 2015 (31,2%). Além disso, 28 países apareceram na lista liderada pelo Brasil (33,3%), seguido de China (10,4%). Utilizaram-se 27 modelos de adaptação transcultural diferentes. Entretanto, o proposto por Beaton e colaboradores foi citado em 47(49,0%) artigos, e o de Brislin em 12 (12,5%). CONCLUSÕES Não há consenso sobre adaptação transcultural, entretanto todos os métodos coincidiram na utilização da etapa de retrotradução. Além disso, diversos estudos em diferentes idiomas e países apontaram a aceitabilidade internacional do método desenvolvido por Beaton e colaboradores
