1. Vegetation mapping of Serra do Cipo National Park (MG, Brasil) and its relation with morphometrical variables. / Classificação da vegetação do Parque Nacional da Serra do Cipó (MG) e sua relação com variáveis morfométricas
The following work maps the vegetation cover of Serra do Cipó National Park, Minas Gerais, Brazil, and correlates the flora distribution to the occurrence of the local morphometric variables: altitude, slope and face orientation, vertical and horizontal curvatures. Its objective is to provide some environment conditional information to the Park and to devel

2. Desempenho de populações segregantes de algodoeiro obtidas por três métodos de hibridação
CHAPTER I - The objectives of this research were to make predictions on segregant populations performance on upland cotton as for selection, using the method proposed by Jinks and Pooni (1976), as well as to identify amongst three different crossing methods, which will originate the most promising population for selection purposes. The present work was condu

4. Para além de pioneiros e forasteiros : outras histórias do oeste do Paraná
The present essay has the purpose of discussing the many memories in dispute in the West of Paraná, having as base the Municipal District of Santa Helena and other stories that emerge from this tension. Produced in different moments, those versions refer to social processes developed between 1950 and 2005 and relate the place to the regional. I approach, at

5. Deletion endpoint allele-specificity in the developmentally regulated elimination of an internal sequence (IES) in Paramecium.
Ciliated protozoa undergo thousands of site-specific DNA deletion events during the programmed development of micronuclear genomes to macronuclear genomes. Two deletion elements, W1 and W2, were identified in the Paramecium primaurelia wild-type 156 strain. Here, we report the characterization of both elements in wild-type strain 168 and show that they displ

6. Contrasted modes of evolution in the same genome: allozymes and adaptive change in Heliconius.
Butterflies in the South American genus Heliconius have undergone a spectacular adaptive radiation (with convergent evolution between some lines) in their color patterns; this has been produced by natural selection for muellerian mimicry. The genetic basis of this radiation, shown by crossing highly differentiated races within two of the species, is homozygo
