The objective of this study was to characterize the spatial distribution pattern at different altitude gradients as well as to investigate the flora associated with A. nahoumii, considered to be endemic and vulnerable. The study was carried out in Serra da Jibóia, Santa Teresinha, Bahia, Brazil. An inventory was conducted of young and adult A. nahoumii specimens along with taxonomic identification and quantification of the associated species. The cover percentage of A. nahoumii, rock slope, organic matter percentage and exposed rock percentage were calculated, as well as the following phytosociological parameters: absolute density, relative density, absolute frequency, relative frequency, and dominance of A. nahoumii. For the spatial distribution, three indices were tested (Morisita, McGuinnes and Payandech). Canonical correspondence analysis was also applied to test the association of the environmental variables with the species in the community. A total of 1,660 individuals were encountered and classified according to taxonomy in 17 families, 25 genera and 28 species. The spatial distribution pattern of the A. nahoumii population is aggregate. The results demonstrate that the population structure of A. nahoumii is stable, but events such as fires and extractive exploitation make the species vulnerable, along with the other species that inhabit the area. |

Common bean (Phaseolus vulgaris L.) is part of the daily diet of over 300 million people in the world and is a staple food of low-income populations, due to its high protein content. Many authors have proposed a further improvement by breeding methods that exploit the existing genetic variability. The objective of this research was to evaluate the genetic potential of segregating bean populations with variability for several traits and conducted by different breeding methods. The F2 segregating population was developed from a cross of the parental genotypes CNFC 7812 and CNFC 8056.One hundred and fifty randomly taken F2 plants originated the segregating populations, which were conducted until the fifth generation by the following breeding procedures: Single Seed Descent (SSD), Bulk and Bulk within F2. The total grain protein content of the F5 families was then analyzed. It was concluded that there was enough genetic variability in the cross under study. The Bulk method proved to be the most efficient since it generated families with superior averages for the trait protein content in comparison with the other breeding methods. |
