Heranças Globais Memórias Locais é uma revista semestral que apresenta os resultados do projeto de investigação ação em curso no Centro de Estudos Sociais da Universidade de Coimbra financiando pela FCT com o nome “Heranças Globais: a inclusão dos saberes das comunidades no desenvolvimento integrado do território” (SHRH/BPD/76601/2011). Procura dar voz aos processos de mudança que incidem sobre os patrimónios e nas heranças em diferentes comunidades locais envolvidas em processos de globalização. Procura reunir reflexões, disseminar visões e apresentar propostas de trabalho. Neste primeiro número são apresentados os resultados da investigação efetuada em 2012. Num primeiro bloco apresentam-se as propostas metodológicas desenvolvidas no âmbito da poética da intersubjetividade. No segundo bloco apresentamos um conjunto de textos que refletem a metodologia da poética da intersubjetividade na resolução de conflitos. Num terceiro bloco apresentamos as metodologias desenvolvidas através da utilização das narrativas biográficas como procedimento de tradução na construção da ecologia dos saberes no âmbito da sociologia das ausências e da sociologia das emergências. Num quarto bloco apresentamos um conjunto de experiências em trono da viagem e da análise da poética do espaço. Finalmente apresentamos alguns trabalhos que estão em desenvolvimento no ano de 2013.

The integration of Biographical Knowledge in research processes is a methodological proposal of critical empiricism that shifts the centre of production of knowledge to the research objects. We try to show haw Biographical Narratives can allow bypassing the locks and the deviations from real observation by the researcher and focus is work on actors in process. In the critique of the Eurocentric paradigm and is production of hegemonic scientific discourses by Bonaventura Sousa Santos (Santos, 2000) proposes the "south epistemologies" as a research process and the inclusion of knowledge of actors as the research field. In the article we will try to look at the process of production of biographical narratives using the tools of south epistemological proposal. We start reviewing the methodologies working on biographical objects. Then we present the preliminary studies and research we have been doing in communities in southern Mozambique in Djabula Community Centre. These results should be completed with other works on the ground, and now we opened as a collaborative process discussion on African Studies community. The project will be completed in the coming months, through the proposal of a "House of memories" to develop with the local population through articles, stories, sounds and dances that are chosen and will support the chosen narratives by the community. The projects created with local players, from their problems allow rapprochement and dialogue between the different knowledge.

Intense male-male competition for females may drive the evolution of male morphological dimorphism, which is frequently associated with alternative mating tactics. Using modern techniques for the detection of discontinuous allometries, we describe male dimorphism in the Neotropical harvestman Longiperna concolor, the males of which use their elongated, sexually dimorphic legs IV in fights for the possession of territories where females lay eggs. We also tested three predictions related to the existence of alternative mating tactics: (1) if individuals with relatively longer legs IV (majors) are more likely to monopolize access to reproductive resources, they are expected to remain close to stable groups of females more than individuals with relatively shorter legs IV (minors) do; (2) if minors achieve fertilization by moving between territories, they are expected to be less faithful to specific sites; and (3) majors should be observed in aggressive interactions more often. We individually marked all the individuals from a population of Longiperna during the reproductive season and recorded the location of each sighting for males and females as well as the identity of males involved in fights. Majors were more likely to have harems, and large majors were even more likely to do so. Majors were more philopatric and all males involved in fights belonged to this morph. These results strongly suggest that the mating tactic of the majors is based on resource defense whereas that of the minors probably relies on sneaking into the territories of the majors and furtively copulating with females.
