Description : M. Flower, écologue, nous propose une étude sur "L'empreinte carbone : ka sa yé menm ?". L'empreinte carbone mesure le volume de dioxyde de carbone (CO2) émis par la combustion d'énergies fossiles, par les entreprises ou les êtres vivants. Comment nos comportements individuels sont-ils chargés en carbone ? Et comment réduire ses effets ?

Description : Antarctica is a continent of enigmas. Stunning geographic beauty belies its inhospitable climate. Covered a mile thick in ice, it is the world's largest desert. Fossil ferns found in its mountains speak of its prehistory as a tropical rainforest, but now is largely devoid of life. Its most famous inhabitant, the penguin, is thought of as a flightless bird, but soars underwater much as a falcon glides the sky. Perhaps one of the greatest enigmas is the contrast between the terrestrial and marine environments. On land, monochromatic snow and ice support little life, yet the sea teams with life, life that expresses itself with the full rainbow of colors. Color is but one manifestation of chemical ecology. The Antarctic benthos supports an extensive community of predators and prey, competitors and facilitators. A harsh geographic history has contributed to marine diversification and enhanced what we now recognize as a rich flora and fauna, commensurate in some instances with temperate kelp forests and even approaching the richness of tropical marine environments. Not surprisingly, Antarctic benthic ecology is highly dependent on chemical mediation of interspecific interactions, interweaving chemodiversity with biodiversity in a classical yin and yang feedback loop. The evolution of selective chemical defenses facilitates drug discovery research, producing suites of metabolites that inform structure-activity studies and add breadth to bioactivity profiles. This presentation will focus on recent and contextual research from our lab which has demonstrated the potential for new biomedical lead molecules and scaffolds from these difficult to access biological resources.

Résumé : International audience
Sea cows (manatees, dugongs) are the only living marine mammals to feed solely on aquatic plants. Unlike whales or dolphins (Cetacea), the earliest evolutionary history of sirenians is poorly documented, and limited to a few fossils including skulls and skeletons of two genera composing the stem family of Prorastomidae (Prorastomus and Pezosiren). Surprisingly, these fossils come from the Eocene of Jamaica, while stem Hyracoidea and Proboscidea - the putative sister-groups to Sirenia - are recorded in Africa as early as the Late Paleocene. So far, the historical biogeography of early Sirenia has remained obscure given this paradox between phylogeny and fossil record. Here we use X-ray microtomography to investigate a newly discovered sirenian petrosal from the Eocene of Tunisia. This fossil represents the oldest occurrence of sirenians in Africa. The morphology of this petrosal is more primitive than the Jamaican prorastomids' one, which emphasizes the basal position of this new African taxon within the Sirenia clade. This discovery testifies to the great antiquity of Sirenia in Africa, and therefore supports their African origin. While isotopic analyses previously suggested sirenians had adapted directly to the marine environment, new paleoenvironmental evidence suggests that basal-most sea cows were likely restricted to fresh waters.

Résumé : International audience
The high proportion of crystallized apatite forming the bones and teeth should theoretically allow the use of fission track analysis to date vertebrate fossils when burying of the fossiliferous series did not subject them to temperatures exceeding 60 degrees C. However several major obstacles arise such as the complexity of fossils' internal structures, diagenetic modifications and substitutions of the hydroxyapatite by other minerals, and massive U uptake or loss during diagenesis. In this work, those various problems are addressed combining optical microscope observation of the fossils, a systematic fission track analysis of the best samples, alpha and gamma spectrometry and Secondary Ion Mass Spectrometry. Even if the problems caused by internal structures and mineral substitutions can be solved, U movements in and out of the fossils are generally too complex to allow fission track analysis dating of the fossils.

Résumé : International audience
Rainbow is a dome-shaped massif at the 36°14′N nontransform offset along the Mid-Atlantic Ridge. It hosts three ultramafic-hosted hydrothermal sites: Rainbow is active and high temperature; Clamstone and Ghost City are fossil and low temperature. The MoMARDREAM cruises (2007, 2008) presented here provided extensive rock sampling throughout the massif that constrains the geological setting of hydrothermal activity. The lithology is heterogeneous with abundant serpentinites surrounding gabbros, troctolites, chromitites, plagiogranites, and basalts. We propose that a W dipping detachment fault, now inactive, uplifted the massif and exhumed these deep-seated rocks. Present-day deformation is accommodated by SSW-NNE faults and fissures, consistent with oblique teleseismic focal mechanisms and stress rotation across the discontinuity. Faults localize fluid flow and control the location of fossil and active hydrothermal fields that appear to be ephemeral and lacking in spatiotemporal progression. Markers of high-temperature hydrothermal activity (∼350°C) are restricted to some samples from the active field while a more diffuse, lower temperature hydrothermal activity (<220°C) is inferred at various locations through anomalously high As, Sb, and Pb contents, attributed to element incorporation in serpentines or microscale-sulfide precipitation. Petrographic and geochemical analyses show that the dominant basement alteration is pervasive peridotite serpentinization at ∼160–260°C, attributed to fluids chemically similar to those venting at Rainbow, and controlled by concomitant alteration of mafic-ultramafic units at depth. Rainbow provides a model for fluid circulation, possibly applicable to hydrothermalism at oceanic detachments elsewhere, where both low-temperature serpentinization and magmatic-driven high-temperature outflow develop contemporaneously, channeled by faults in the footwall and not along the detachment fault.
