RESUMO -A mirmecocoria é importante processo para a dinâmica vegetacional em diferentes ecossistemas, principalmente na região neotropical. Entretanto, a relação entre formigas e diásporos não mirmecocóricos é pouco documentada em ambientes da América do Sul. Dessa forma, este estudo teve por objetivos quantificar a taxa de remoção de diásporos não mirmecocóricos em fragmento de Cerrado e verificar se a presença de recursos energéticos e, ou, a abundância dos diásporos são determinantes para sua remoção por formigas. Formigas removeram 19,81% dos diásporos não mirmecocóricos coletados, e a presença de recursos energéticos influenciou significativamente essa remoção, não sendo significativa a relação entre abundância e remoção. Como a maioria dos diásporos coletados não era do tipo carnoso, com pouco ou nenhum recurso energético disponível para formigas, a importância da mirmecofauna para a remoção de diásporos não mirmecocóricos pode estar sendo subestimada. NON MYRMECOCHORUS DIASPORES DISPERSION BY ANTS: TYPE AND DIASPORE ABUNDANCE INFLUENCE ABSTRACT -The myrmecochory is an important process for the vegetation dynamic in different ecosystems
In The Principles of Mechanics, physicist Heinrich Hertz argues that instead of replying to the question "what is force?" like physicists and philosophers had been doing unsuccessfully, Newtonian physics should be reformulated without considering "force" a basic concept. Decades after Hertz's book, Ludwig Wittgenstein considered the physicist's proposal a perfect model for how philosophical problems should be solved, to the point that he made it the foundation of his way of doing philosophy. This article addresses Wittgenstein's way of doing philosophy, while it also proposes the reason why he failed in solving the philosophical problems -as did Hertz in his project on reformulating Newtonian physics without considering the concept "force". And to illustrate Wittgenstein's failure, it examines his disputes with mathematicians Kurt Gödel and Alan Turing on the foundations of mathematics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
