Response of littoral chironomid community and organic matter to late glacial lake level and environmental changes at Lago dell'Accesa (Tuscany, Italy).

International audienceThis study focuses on the response of lacustrine littoral chironomid communities to late glacial changes in limnological, environmental and climate conditions in the Mediterranean context. Late glacial chironomid (Diptera: Chironomidae) assemblages, organic petrography and geochemistry were analysed in a sediment core from the littoral zone of Lago dell'Accesa (Tuscany, Italy), where the lake-level fluctuations and the vegetation history have been previously reconstructed. Comparison of the chironomid stratigraphy to other proxies (pollen assemblages, organic petrography and geochemistry, lake-level) and regional climate reconstruction suggested the predominant influence of lake-level changes on the littoral chironomid fauna. The main lowering events that occurred during the Oldest and the Younger Dryas were followed by higher proportions of taxa typical of littoral habitats. A complementary study of organic matter suggested the indirect impact of lake-level on the chironomids through changes in humic status and habitat characteristics, such as the type of substrate and aquatic macrophyte development. Several chironomid taxa, such as Glyptotendipes, Microtendipes and Cricotopus type patens, were identified as possible indicators of low lake-level in the late glacial records. Nevertheless, this study suggested that parallel analyses of organic matter and chironomid assemblages may be needed to circumvent misinterpretation of littoral chironomid assemblage stratigraphy. There was a weak response of the chironomid assemblages to small lake-level lowerings that corresponded to the Older Dryas and Preboreal oscillations. A higher level of determination, e.g. to the species group level, may be necessary to increase the sensibility of the indicators to lake-level changes

Recherches en terrain difficile : le cas du culte traditionnel annobonais (île d’Annobon, Guinée équatoriale, XVe-XXe siècle)

Mener une enquête de terrain en Guinée équatoriale est une tâche complexe, coûteuse et incertaine. Mais se pencher sur l’aspect historique du culte annobonais permet d’en éclairer le présent même si les rituels évoluent très vite. Partager cet article et les connaissances acquises est l’occasion d’ouvrir un dialogue avec d’autres chercheurs mais aussi des Annobonais qui s’y intéressent. Car c’est aussi grâce à des témoignages écrits par des insulaires qu’il a été possible de reconstituer partiellement l’évolution de ce culte entre le XVe et le XXe siècle. De ce culte, il apparaît aujourd’hui qu’il a fortement contribué à rapprocher la population, grâce notamment à ses confréries. Il accompagne les insulaires de façon très codifiée aux différentes étapes de leur vie et au-delà, grâce à un culte des ancêtres. Il a aussi ancré la population géographiquement en attribuant à différents lieux de l’île une fonction bien définie.Conducting a field survey in Equatorial Guinea is a complex, expensive and uncertain task. Fortunately, to look at the historical aspect of the Annobonese cult allows for shedding light on the present even if the rituals evolve very quickly. Sharing this article and the knowledge gained is an opportunity to open a dialogue not only with other researchers, but also with interested Annobonese. Testimonies written by islanders aided greatly in reconstituting the evolution of this cult between the 15th and the 20th centuries. It appears today this cult has greatly contributed to bringing the population closer, in particular its brotherhoods. The cult accompanies islanders in a very codified way at different stages of their life and beyond, thanks to ancestor worship. It has also anchored the population geographically by giving different places of the island well-defined functions
