Echinoids are common members of Antarctic zoobenthos, and different groups can show important trophic diversity. As part of the ANT-XXIX/3 cruise of RV Polarstern, trophic plasticity of sea urchins was studied in three neighbouring regions (Drake Passage, Bransfield Strait and Weddell Sea) featuring several depth-related habitats offering different trophic environments to benthic consumers. Three families with contrasting feeding habits (Cidaridae, Echinidae and Schizasteridae) were studied. Gut content examination and stable isotopes ratios of C and N suggest that each of the studied families showed a different response to variation in environmental and food conditions. Schizasteridae trophic plasticity was low, and these sea urchins were bulk sediment feeders relying on sediment-associated organic matter in all regions and/or depth-related habitats. Cidaridae consumed the most animal-derived material. Their diet varied according to the considered area, as sea urchins from Bransfield Strait relied mostly on living and/or dead animal material, while specimens from Weddell Sea fed on a mixture of dead animal material and other detritus. Echinidae also showed important trophic plasticity. They fed on various detrital items in Bransfield Strait, and selectivity of ingested material varied across depth-related habitats. In Weddell Sea, stable isotopes revealed that they mostly relied on highly 13C-enriched food items, presumably microbially-reworked benthic detritus. The differences in adaptive strategies could lead to family-specific responses of Antarctic echinoids to environmental and food-related changes. [less ▲]

This article deals with a phenomenon which appears in a particular context: the institutionalisation of international law between 1869 (creation of the Revue de droit international et de législation comparée) and 1873 (birth of the Institut de Droit International), through the international networks of the Belgian lawyer Gustave Rolin-Jaequemyns. He was close to Pasquale Mancini, John Westlake, James Lorimer, Franz Von Holtzendorff, but also to the least-known Michael Corr-Van der Maeren, a publicist. Until this period of crystallisation this field was not structured and represented an aggregate of individualities. What can we say about such a process of institutionalisation on the basis of unpublished archives? The history of international law, until today, especially studied by lawyers, was very neglected by historians, whose methods and sources are complementary to those of the lawyer. Our contribution wishes to contribute to the development of a history of international law written by historians. [less ▲]

This PhD thesis – composed of a series of five papers tied together by an introduction and conclusions – explores the functioning of an Incident Reporting System used in a high-risk organization. It aims at understanding how safety is actually constructed by and through this reporting system and what it actually does to the meaning of safety when it prescribes a set of sociotechnical practices. From a conceptual point of view, this PhD thesis departs from classical risk or vulnerability analyses which tend to measure factors in order to produce what are supposed to be “objective” results and “manageable” recommendations for decision makers. By relying on a constructivist understanding of vulnerability, this research explores and characterizes situations and events the consequences of which are ambiguous and the probabilities of which are uncertain. It thus broadens the scope of classical risk or vulnerability analyses and complements it with a qualitative and discourse-based attention to organizational, cultural and ethical questions. [less ▲]

Arrêt après arrêt, elle consolide la norme attaquée ou au contraire redessine – ou presse le législateur de redessiner – les contours de cette branche du droit fortement marquée par son histoire. Elle se penche sur un peu plus de trente arrêts prononcés par la Cour constitutionnelle, principalement depuis 2008, dans les domaines suivants : le travail à temps partiel (chapitre 1), le droit de la non-discrimination (chapitre 2), certaines questions intéressant le licenciement, à savoir la durée du préavis, les mesures destinées à stimuler l’employabilité, la motivation, la notion de rémunération en cours en cas de réduction temporaire des prestations de travail, et l’indemnité d’éviction du représentant de commerce (chapitres 3 à 7), les distinctions entre employés et ouvriers autres que les conditions de licenciement (chapitre 8), la procédure de réorganisation judiciaire (chapitre 9) et la prescription (chapitre 10).

Antarctica currently undergoes strong and contrasted impacts linked with climate change. While the West Antarctic Peninsula is one of the most rapidly warming regions in the world, resulting in sea ice cover decrease, in some parts of East Antarctica sea ice cover tends to increase, possibly in relation with changes in atmospheric circulation. Changes in sea ice cover are likely to influence benthic food web structure through modifications of benthic-pelagic coupling, disruption of benthic production and/or modifications of benthic community structure (i.e. resource availability for benthic consumers). Here, we studied shallow (0-20 m) benthic food web structure on the coasts of Petrels Island (Adélie Land, East Antarctica) during an event of unusually high spatial and temporal (two successive austral summers without seasonal break-up) sea ice cover. Using stable isotope ratios of C, N and S, we examined importance of several organic matter sources (benthic macroalgae, benthic biofilm, sympagic algae, suspended particulate organic matter and penguin guano) for nutrition of over 20 taxa of benthic invertebrates (sponges, sea anemones, nemerteans, sessile and mobile polychaetes, gastropods, bivalves, sipunculids, pycnogonids, amphipods, sea stars, sea urchins and sea cucumbers) spanning most present functional guilds. Our results provide insights about how Antarctic benthic consumers, which have evolved in an extremely stable environment, might adapt their feeding habits in response to sudden changes in environmental conditions and trophic resource availability.

Sustainable agriculture relies on the development of environmentally friendly methods of crop production. Therefore, alternative solutions are required to decrease insecticide use and to promote the efficacy of natural enemies against insect pests. Investigating the sexual behavior of lady beetles is of practical relevance, because these insects could be used to reduce plant-feeding insect populations in crop fields by taking advantage of their predatory behavior. In this context, the objective of this PhD thesis was twofold: (1) a fundamental research that focuses on the identification of the sex pheromone of Harmonia axyridis (Pallas) and (2) an applied approach aimed at elaborating semiochemicals slow-release dispensers with these compounds, in order to attract individuals in cultivated fields. We have demonstrated that virgin females of H. axyridis display a typical male-calling behavior in presence of prey, which is associated with the release of a pheromonal blend that is highly attractive for conspecific males. Dynamic headspace sampling and subsequent chemical analyses allowed the characterization of this sex pheromone. Finally, we focused on the development of a formulation releasing a combination of semiochemicals that attract aphid predators. The formulation, composed of alginate beads, was optimized under laboratory conditions. The release rate of the formulation was assessed by dynamic headspace sampling coupled with adsorbent trapping. The formulation was efficient at attracting two natural enemies of aphids. All these results are discussed in the context of sustainable agriculture, with the use of semiochemicals, and especially pheromones, as potential tools to enhance current cropping systems. In near future, the application of such molecules, based on strong knowledge of insect olfaction, is expected to increase considerably with the development of new methods aimed at attracting predators and/or parasitoids. In addition, improvements of experimental devices, such as the elaboration of slow release dispensers, are suggested in the last chapter of this PhD thesis. [less ▲]

Faire l’histoire de l’édition en Belgique à partir de l’apparition du livre imprimé soulève un certain nombre de problèmes en fait de délimitation du domaine et de construction de l’objet. Les plus évidents touchent aux avatars politiques et linguistiques que les territoires formant l’État belge ont connus du XVe siècle à la fin du XXe siècle. D’autres proviennent du rapport de force très inégal qui s’est établi, à partir de la première moitié du XIXe siècle, entre le système de production du livre en Wallonie et à Bruxelles et l’édition française, avec les effets que ce rapport y exercera durablement en termes d’identité culturelle et de rayonnement, de structures de production et de diffusion, mais aussi de créneaux privilégiés. Ces problèmes et d’autres encore – dont témoigne une historiographie volontiers cantonnée à « l’histoire du livre et de l’imprimerie » – méritent d’être réexaminés dans la perspective de la publication imminente d’une Histoire de l’édition en Belgique profilant, du XVe au XXIe siècle, ses principales lignes de faîte. Histoire de l’édition et de ses pratiques – non du livre et de ses techniques. Histoire de l’édition dans toute son extension et à différents niveaux – non de la seule édition littéraire ou lettrée. Histoire d’un espace des possibles ayant su, dans certains secteurs, tirer force et spécificité de contraintes puissamment subies. [less ▲]
