Última Morphological divergence rate tests for natural selection: uncertainty of parameter estimation and robustness of results Genet. Mol. Biol. Monteiro,Leandro R.; Gomes-Jr,José L.. In this study, we used a combination of geometric morphometric and evolutionary genetics methods for the inference of possible mechanisms of evolutionary divergence. A sensitivity analysis for the constant-heritability rate test results regarding variation in genetic and demographic parameters was performed, in order to assess the relative influence of uncertainty of parameter estimation on the robustness of test results. As an application, we present a study on body shape variation among populations of the poeciliine fish Poecilia vivipara inhabiting lagoons of the quaternary plains in northern Rio de Janeiro State, Brazil. The sensitivity analysis showed that, in general, the most important parameters are heritability, effective population size and...

Holymenia clavigera (Herbst) and Anisoscelis foliacea marginella (Dallas) (Hemiptera: Coreidae) are distributed in southern Brazil and belong to the poorly studied tribe Anisoscelini. Preliminary observations indicate an ample coexistence of these species in terms of host-plant use. There is also a strong similarity regarding egg and nymph morphology. We characterized and compared their ontogenetic trajectories by means of growth curves and multivariate ontogenetic allometry, since the only apparent difference between these species is a remarkable growth in the hind tibia of A. foliacea marginella. Because their hind tibia is similar in the early instars, the shape variation of this structure was quantified by the thin plate splines function with the...
