1. Genetic structure in bracatinga populations (Mimosa scabrella Benth.) for quantitative traids and isozyme markers. / Estrutura genética em populações de bracatinga (Mimosa scabrella Benth. ) por marcador isoenzimático e caracteres quantitativos.
Mimosa scabrella Bentham (Bracatinga), is a native tree species of Atlantic Forest, of restricted occurrence to the Southwest and South of Brazil (RS, SC, PR and SP). The species comes being cultivated in the Brazil south and in the other countries as Costa Rica and Ruanda, for the most varied ends. But, although the species has a varied ends, lack studies i

2. Multiple evolutionary origins of the fungus causing Panama disease of banana: Concordant evidence from nuclear and mitochondrial gene genealogies
Panama disease of banana, caused by the fungus Fusarium oxysporum f. sp. cubense, is a serious constraint both to the commercial production of banana and cultivation for subsistence agriculture. Previous work has indicated that F. oxysporum f. sp. cubense consists of several clonal lineages that may be genetically distant. In this study we tested whether li

3. Replicated evolution of trophic specializations in an endemic cichlid fish lineage from Lake Tanganyika
The current phylogenetic hypothesis for the endemic Lake Tanganyika cichlid fishes of the tribe Eretmodini is based solely on morphology and suggests that more complex trophic morphologies derived only once from a less specialized ancestral condition. A molecular phylogeny of eretmodine cichlids based on partial mitochondrial DNA cytochrome b and control-reg
