Abstract

Most of tropical rainforest tree species are dispersed by animals. The role of rodents in seed dispersal has been poorly documented in African rainforests. Considering that rodents are less affected than large mammals by selective hunting, they could therefore play a crucial role in seed dispersal of some species.&#13;This study was carried out in a moist semi-deciduous forest in Cameroon, within an FSC-certified forest concession. This work aimed to deepen knowledge on the roles of two African rodent species, Cricetomys emini and Funisciurus pyrropus, in seed dispersal. In parallel, the effectiveness of three seed marking methods for monitoring dispersion was assessed. Interaction with olfactory molecules was also explored through the introduction of an attractive molecule, the sulcatone, to promote seed removal by rodents and through a preliminary study of the volatiles emitted by the arils of two species of the Myristicaceae family. A total of 454 seeds were marked with magnets/fluorescent thread tags/PIT tags in order to obtain dispersion data via detection with a magnetic detector/UV lamp/RFID system. Finally, hoards of both rodent species were searched and the seeds within were identified.&#13;This study showed a scatter-hoarder behaviour for F. pyrropus with seeds found up to 37m and 4% of the marked seeds recovered whole and buried at a maximum depth of 10 cm. The caches of F. pyrropus contained 30% potentially viable seeds. The seeds taken away by C. emini were not found within a radius of 50m, which suggests a dispersal distance greater than 50m. Thirty-five % of the seeds were whole and 6 % potentially viable or viable in the burrows of C. emini.&#13;The magnetic detector had the advantage of being easier to handle in the vegetation, detecting tags faster and deeper in the soil. However, it requires an appropriate soil, is annoying for C. emini because the magnets come out of the seeds to cling to each other in his cheek pouches, and the detector gives false detections. In contrast, the RFID system does not give false detections and PIT tags have a unique identifier, they can be found less deeply than magnets but do not interfere with rodents. The thread tags were a source of discomfort for both C. emini and F. pyrropus, were less easy to find but are very cheap.&#13;The VOCs profiles of the fruits of both Myristicaceae species are very complex and it is probably in their whole that they could have an olfactory effect on rodents. There was a significant dependence in seed removal depending on whether sulcatone was present or not. La grande majorité des arbres en forêt dense humide tropicale sont dispersés par des frugivores. Le rôle des rongeurs dans la dispersion des graines a jusqu’à présent été très peu documenté dans les forêts denses humides africaines. Or, les rongeurs sont moins touchés par la chasse sélective et pourraient donc avoir un rôle d’autant plus important dans la dispersion des graines de certaines essences.&#13;Réalisé en forêt dense humide semi-caducifoliée camerounaise, au sein d’une concession forestière certifiée FSC, ce travail ambitionne d’approfondir les connaissances sur les rôles de deux espèces de rongeurs africains, Cricetomys emini et Funisciurus pyrropus, en tant que disperseurs de graines. En parallèle, l’efficacité de trois méthodes de marquage de graines pour le suivi de la dispersion a été appréhendée. Enfin, l’interaction avec des molécules olfactives a également été explorée via la mise en place d’une molécule attractive, la sulcatone, et via une étude préliminaire des volatils émis par l’arille de deux essences de la famille des Myristicaceae. Au total 454 graines ont été marquées à l’aide d’aimants/de fils fluorescents/de PIT tags dans le but d’obtenir des informations sur la dispersion via la détection avec un détecteur magnétique/une lampe UV/une antenne et un lecteur RFID. Enfin, des cachettes des deux espèces de rongeurs ont été fouillées et les graines présentes ont été identifiées.&#13;Cette étude a montré un comportement de scatter-hoarder pour F. pyrropus avec des graines retrouvées jusqu’à 37m et 4% des graines marquées récupérées entières et enterrées à max. 10 cm de profondeur. Les caches de F. pyrropus présentaient 30% de graines potentiellement viables. Les graines emportées par C. emini n’ont pas été retrouvées dans un rayon de 50m, ce qui laisse présager une dispersion supérieure à 50m. Les terriers de C. emini contenaient 35% de graines entières et 6% de graines potentiellement viables ou viables.&#13;Le détecteur magnétique présentait l’avantage d’être plus aisé à manipuler dans la végétation, de détecter des tags plus rapidement et plus profondément dans le sol. Cependant, il nécessite un sol approprié, est gênant pour C. emini car les aimants sortent des graines pour s’accoler les uns aux autres dans ses poches jugales, et le détecteur donne de faux-positifs. A l’inverse, le système RFID ne donne pas de faux-positifs et les PIT tags possèdent un identifiant unique, ils peuvent être retrouvés moins profondément que les aimants mais ne gênent pas les rongeurs. Les fils gênaient fortement C. emini et F. pyrropus, étaient moins faciles à retrouver mais présentent l’avantage d’être très peu coûteux.&#13;Les profils en VOCs des diaspores des deux espèces de Myristicaceae sont très complexes et c’est probablement dans leur globalité qu’ils pourraient avoir un effet olfactif sur les rongeurs. Il y avait une dépendance significative dans l’enlèvement des graines selon que la sulcatone soit présente ou pas.

Abstract

This thesis has been written as a roadmap for the Cluster TWEED in order to develop a whole digital marketing strategy for their brand “REWallonia”. The different steps to follow have been detailed in order to achieve the mission given by the company to the student. It first starts with a situation analysis: micro, macro and internal analyses are performed in order to have a better understanding of the environment in which the organization operates. The second step was then to set appropriate objectives aligned with the general business strategy of the company, taking into account the strengths and weaknesses of TWEED. Those objectives are mainly digital marketing objectives as improving the ranking of the website on Google, attract the visitors to our website and make them stay on it and finally turn those users into advocates of our brand. The third step was to define strategies to reach those objectives. For this, various tools are used such as a Search Engine Optimisation strategy, email marketing, website design and usability, social media marketing, etc. The fourth step is to set Key Performance Indicators to measure the results.

Abstract

The present publication is dedicated to the expressive self-portraits by Jean-Michel Basquiat and covers his lifelong intensive study of the self. In Basquiat's œuvre the self-portrait, one of the major subjects of art history, occupies a central position that has not been examined to date. Jean-Michel Basquiat's self-portraits are regarded as being among the most important of his radical creative works. In addition to some 50 specific portraits of himself, we can also see his series of likenesses of African-American men as concealed reproductions of the artist. Not least because Basquiat, who was affected himself by everyday racism, identified with his heroes, saints and martyrs as he portrayed them. Thus his major topics from identity, discrimination and prejudice to capitalism, the market and oppression are all to be found in these key works

Abstract

Quelle est l'histoire du graffiti à Bruxelles ? Quelles sont ses origines, ses règles et ses pratiques ? Qui sont ses artistes de l'ombre ? Dehors ! Le graffiti à Bruxelles tente de répondre à ces questions et met à l'épreuve le double problème de la place du graffiti dans l'art et dans la ville, en interrogeant son rôle dans l'enrichissement artistique de la capitale de l'Europe. Adrien Grimmeau a analysé tous les parcours, de la rue aux galeries, en s'appuyant sur une documentation rare et des témoignages originaux, riches et colorés, dans l'esprit même des nouveaux codes de lecture nés de cette esthétique irrégulière. Pour la première fois, des graffeurs des générations successives ont ouvert leurs archives et partagé leur passion commune pour l'art urbain. Ce premier ouvrage de référence sur le sujet fait passer « l'art de la rue » de l'éphémère à l'indélébile. L'exposition inspirée du livre "L'art du graffiti à Bruxelles" se tient au Musée d'Ixelles (rue J. Van Volsem 71, 1050 Bruxelles) du 16 juin au 4 septembre 2011.

Abstract

Long before China promulgated the official One Belt One Road initiatives, vast networks of cross-border exchanges already existed across Asia and Eurasia. The dynamics of such trade and resource flows have largely been outside state control, and are pushed to the realm of the shadow economy. The official initiative is a state-driven attempt to enhance the orderly flow of resources across countries along the Belt and Road, hence extending the reach of the states to the shadow economies. This volume offers a bottom-up view of the transborder informal exchanges across Asia and Eurasia, and analyses its clash and mesh with the state-orchestrated Belt and Road cooperation. By undertaking a comparative study of country cases along the new silk roads, the book underlines the intended and unintended consequences of such competing routes of connectivity on the socio-economic conditions of local communities.

Abstract

This addresses current advances and challenges in fisheries and aquaculture science. Exposure of larval fish to elevated temperatures during embryological development may induce craniofacial and morphological alterations, which are suggested possible impacts of global warming. Molecular markers shed new light on the ontogenetic migration of stream fishes. Fast growth rates, early age at maturity, moderate fecundity, and diverse diet explain the potential for introduced fishes to dominate fish communities in their native and introduced range. Taking videos of marine benthic habitats supports low-impact, real-time monitoring of species occurrence. Among heavily fished species, almost half had outdated demographic assessments that would benefit from the integration of data from fisheries sources and improved collaboration among fishery stakeholders and managers. The continued growth of aquaculture will depend upon developing feeds that improve the growth, oxidative status, and immune response of fed cultured organisms. New aquaculture feedstuffs might be derived from plants or microbes, and new additives would include ghrelins and dietary symbiotics. The effects of these constituents on survival, growth, gut histomorphology, immune response were assessed for cultured freshwater and marine species. The results provide suggestions for advances in aquafeeds for the species studied and for cultured fishes more generally. The scientific advances realized with the use of new tools provide the basis for addressing global challenges to fisheries, aquaculture and for ongoing scientific research.
