Conteúdo:  This thesis consists of six chapters: I. A review of nodulation in the family Leguminosae. This updates the classic work of Allen & Allen (1981) and includes new nodulation records (296 species). The doubtful nodulation status of some species is discussed, and the taxonomic implications are considered. The distribution of nodulation within the Leguminosas was found to be consistent in some tribes, groups and genera: this together with nodule morphology and structure are of considerabletaxonomic value. II. A study of nodule structure, from woody legumes, with special emphasis on caesalpinioid species. This revealed many symbiotic features different from those assumed to be general in legumes,although very similar to those reported in Parasponia, (the only genusof non-legume known to fix nitrogen in symbiosis with rhizobia). In all caesalpinioid, some papillionioid, but no mimosoid species, the bacteria are kept inside infection threads during the whole nitrogen fixing period. III. Root infection and nodule development in a species which does not consistently produce root hairs, Mimosa scabrella. A broad survey of root hair production and location in legumes roots was conducted as a basic study, choosing Mimosa scabrella for this study. Bacterial penetration into roots was found to occur via intercellular movement, prior to the intracellular infection; bacteria inside the cells were enclosed by structure which resemble infection threads; nodule initiation and development appar... Mostrar Tudo

Conteúdo:  ABSTRACT Detecting trends in streamflow and rainfall series can have great significance for proper water resource management. Thus, the objective of this study was to analyze the trends of historical streamflow and rainfall series using nonparametric statistical tests. A historical series of pluviometric and fluviometric gauges, which belong to the hydrometeorological network of the Brazilian Water National Agency in the Santo Antônio River Basin, Brazil, from 1985 to 2014 were used. By applying statistical tests, it was found that the time series are independent and random, and from the total 24 rainfall gauges evaluated, 12 presented nonstationary behavior, exhibiting mostly decreasing trends. Based on the six fluviometric gauges used for the annual streamflow series, only the annual data of one gauge tended to decrease to the minimum streamflow. However, for the monthly series, three gauges showed decreasing trends between July and September. This decrease in streamflow may be a consequence of rainfall reductions, high water demand, and changes in land use and cover.
