Resumo: Este trabalho teve como objetivo avaliar o comportamento de 71 genótipos de leucena, identificar e selecionar os genótipos com elevada produtividade e com estabilidade de produção de forragem. A produtividade de matéria seca comestivel (MSC) dos genótipos de leucena foi obtida par meio de cinco cortes efetuados na estaçao chuvosa e três na estaçao seca, durante 24 meses. A análise de variância conjunta para produçao de MSC foi efetuada, e os parâmetros de estabilidade foram determinados. A analise de variância conjunta da produçao de MSC dos 71 genótipos de leucena mostrou que houve diferença significativa para genótipos, ambientes e interaçao genótipo x ambiente. Seis genótipos de leucena foram selecionados corn base na produção de MSC, nos parâmetros de estabilidade e no coeficiente de determinação. [Evaluation of Genotypes of Leucena in the Semi-Arid Region of Ceara]. Abstract: The objective of this work was to evaluate the performance of 71 genotypes of leucaena and to select the best genotypes based on edible dry matter yield (EDMY) and on stability parameters. EDMY of the leucaena genotypes was obtained by five cuts in the raining season and three cuts in the dry season, on a 24 months basis. A combined analyses of variance for EDMY yield was performed and stability parameters were determined (using the methodology proposed by Eberhart and Russel). The combined ANOVA for the EDMY revealed a significatively difference for genotypes, for environments, and for genotypes x environment. Six genotypes of leucaena were selected on the basis of the EDMY, stability parameters and coefficient of determination.

Species discovery methods utilizing coalescent-based approaches are powerful tools for detecting cryptic lineages within morphological conservative groups, thus being an important methodology of integrative taxonomic research. Crocodilians are a classic example of morphologically conserved group where coalescence-based species delimitation analyses resulted in the discovery of cryptic lineages and potentially new species. In this study, we used several single locus species discovery methods to analyze the phylogenetic diversity of the most widespread alligatorid genus of the Neotropics, the genus Caiman. We analyzed 479 specimens representing all named taxa, with the exception of Caiman crocodilus apaporiensis, and known geographic distribution of these taxa. We observed high lineage diversity within the Caiman crocodilus/yacare complex, ranging from 7 to 10 lineages, and three lineages within Caiman latirostris. We also provide a new dated phylogeny for all the delimited lineages. Oligocene and Miocene events triggered the diversification of the major lineages, with latter Pleistocene events influencing the final diversification of the genus. We demonstrate that the discovered lineages within the Caiman complex are compatible with being species and as such are candidates for an integrated taxonomic analysis. However, it is important to highlight that independent of the future recognition of these lineages as species, it is extremely important to protect these cryptic lineages as unique evolutionary entities, many of which are highly threatened by habitat loss from dam construction projects, tailing dam collapses, mining, agriculture and agricultural run-off across all of South America.
