ABSTRACT
The genetic and morphometric population structures of the semiterrestrial crab Armases angustipes from along the Brazilian coast were examined. The influence of the Central South Equatorial Current on larval dispersal of A. angustipes also was evaluated. Six populations were sampled from estuarine areas in São Luis do Maranhão, Maranhão; Natal, Rio Grande do Norte; Maceió, Alagoas; Ilhéus, Bahia; Aracruz, Espírito Santo; and Guaratuba, Paraná. Patterns of genetic differentiation were assessed using DNA sequence data corresponding to parts of the mitochondrial cytochrome c oxidase subunit 1. Geometric morphometric techniques were used to evaluate morphological variation in shape and size of the carapace and right cheliped propodus. Our results revealed low genetic variability and lack of phylogeographic structure; geometric morphometrics showed statistically significant morphological differentiation and geographic structuring. Our data indicate the absence of possible barriers to gene flow for this mobile species, and no clear correlation of morphological or genetic variation with ocean currents and/or geographic distance. Our results also suggest that historical geological and climatological events and/or possible bottleneck effects influenced the current low genetic variability among the populations of A. angustipes.

O Serviço Nacional de Aprendizagem Industrial (Senai) foi instalado no Paraná em 1943, objetivando capacitar força de trabalho para a indústria. Por meio de imagens e documentos escritos, guardados na Federação das Indústrias do Estado do Paraná, apresentam-se aspectos da formação para o trabalho na escola do Senai de Curitiba, tanto na perspectiva institucional quanto através do discurso dos alunos. Imagens e discursos são aproximados apontando vicissitudes do projeto de formação para o trabalho proposto por essa instituição de cunho privado, que contou com o anteparo público concedido aos industriais para formar trabalhadores, especialmente aprendizes de ofício.
A branch of the Serviço Nacional de Aprendizagem Industrial (Senai) was set up in Paraná in 1943 to train industrial labor. Images and written records held by the Paraná State Federation of Industries depict aspects of technical training at the Senai school in Curitiba, both from an institutional perspective and from the students', through their discourse. A comparison of these images and discourses serves to highlight the vicissitudes of this private institution's vocational training project, which received government support for the instruction of industrial workers, especially apprentices.
