Chez les rongeurs, les interneurones (INs) corticaux sont issus de l’éminence ganglionnaire (EG) médiale (MGE) et caudale (CGE), expriment une combinaison de facteurs définis et migrent tangentiellement puis radialement pour atteindre leur position laminaire définitive. La diversité et la spécification des sous-types d’INs provenant de la MGE ont suscité de nombreuses études, en revanche les mécanismes moléculaires contrôlant la migration et la spécification des INs issus de la CGE demeurent toujours obscurs. Dans cette étude, les voies de migration de ces INs ont été examinées grâce à une lignée de souris rapportrices des interneurones issus de la CGE avant d’analyser le rôle de deux facteurs de transcription, COUP-TFI et COUP-TFII, hautement exprimés dans la CGE. Deux voies de migration non précédemment caractérisées ont alors été identifiées : une voie dorsale (CLMS) où les INs migrent vers l’EG latérale (LGE) et une voie ventrale (CMMS) où les INs migrent vers la MGE. Le CLMS et le CMMS ont donc été analysés, ainsi que la voie de migration caudale (CMS), à différents stades de développement et l’expression spécifique de certains gènes a pu être identifiée. En inactivant conditionnellement COUP-TFI et/ou COUP-TFII dans les INs, les voies de migration sont altérées ainsi que l’expression des marqueurs moléculaires. Comme probable conséquence, les souris mutantes adultes montrent une distribution altérée des sous-populations d’INs en particulier de celles issues de la CGE. Mon étude a donc permis d’identifier et de caractériser deux nouvelles voies de migration pour les INs provenant de la CGE et a montré que COUP-TFs contribuent à leur modulation. / In rodents, cortical interneurons (INs) originate from the medial (MGE) and caudal ganglionic eminence (CGE) according to precise temporal schedules, express a defined combination of factors, and reach their final laminar position through tangential and radial cell migration. The diversity and fate-specification of MGE-derived interneuron subtypes are well characterized however the molecular mechanisms controlling the migration and specification of CGE-derived INs are still vague. In this study, I have first investigated the migratory paths of cortical INs using a reporter line specific to the CGE, and then I have assessed the involvement of COUP-TFI and COUP-TFII, which are highly expressed in the embryonic CGE during development, in these paths. My data unravelled two major previously non-characterized migratory streams from the subpallium to the pallium: a dorsal stream (CLMS) in which CGE-derived cells migrate to the lateral GE (LGE), and a ventral one (CMMS) in which CGE-derived cells migrate to the MGE. I have characterized both streams and the already well-described caudal stream (CMS) during different stages of development and identified a series of genes expressed in the migrating cells. By inactivating COUP-TFI and/or COUP-TFII in the developing INs, these streams together with their molecular marker expression are perturbed. As a consequence, adult mutant mice have an altered distribution of interneuron subpopulations, particularly the ones derived from the CGE. Taken together, my study identified and characterized two novel CGE-derived interneuron migratory routes to the cortex and showed that COUP-TFs contribute in modulating these paths.

Identitet och tillhörighet är komplexa begrepp som är ytterst viktiga för en individs välmående. Tidigare forskning visar att en individs identitet och tillhörighet påverkas när hen byter land. Syftet med föreliggande studie var att ta reda på vad som händer med en individs identitet när hen tvingas byta land. Jag ville även se om det går att känna tillhörighet i det nya landet och vad som gör att respondenterna känner/inte känner tillhörighet. Åtta semi-strukturerade intervjuer med flyktingar som varit i Sverige mellan 2-10 år genomfördes och analyserades med hjälp av en induktiv tematisk analys. Det finns skilda åsikter kring om identiteten ändras eller inte när en individ tvingas byta land. Tillhörighet går att känna i det nya landet och påverkas av faktorer som självständighet, stöd, boende, mottagande samt att ha någonstans att känna sig hemma. Resultaten diskuteras huvudsakligen utifrån Tajfel och Turners (1979) sociala identitetsteori. Studien bidrar med en ökad förståelse kring flyktingars situation när de kommer till Sverige, gällande identitet och tillhörighet. / Identity and feelings of belongingness are complex concepts that are extremely important for an individual's well - being. Previous research shows that an individual's identity and belongingness are affected when changing country. The purpose of this study was to find out what happens to an individual's identity when forced to change country. I also wanted to see if there is a sense of belongingness in the new country and what makes the respondents feel / don't feel belongingness. Eight semi-structured interviews with refugees that had been in Sweden between 2-10 years were conducted and analyzed using an inductive thematic analysis. There are different opinions about whether the identity changes or not when an individual is forced to change country. Belonging can be felt in the new country and is influenced by factors such as independence, support, accommodation, reception and having somewhere to feel at home. The results are mainly discussed based on Tajfel and Turners (1979) social identity theory. The study contributes to an increased understanding of migrants' situation when they come to Sweden, regarding identity and belonging.

Abstract:The daily movements of roach when migrating between its winter habitat in a stream and its summer habitat in a lake were studied during spring. The main source of food for roach in the lake is zooplankton, which increases in density as temperature rises during spring. The study was based on following the daily movements of tagged fish during spring. The idea was to test if roach, by moving back and forth between the stream and the lake, sample the availability of food in the lake and continue to do so until the food supply reaches a level so that the benefits of higher growth outweigh the risk of predation in the lake. My results showed that roach do indeed swim back and forth between the lake and the river during a period when food availability is uncertain, before all individuals finally move into the lake to stay. This seems to occur at a time when the availability of food is sufficiently large to compensate for the risk of predation in the lake. / SammanfattningI den här undersökningen studeras dygnsaktiviteten hos mört i migration mellan vinterhabitatet i en bäck och sommarhabitatet i en sjö under vårperioden när tätheten av zooplankton i sjön förväntas öka. Mörtens huvudsakliga föda i sjön är zooplankton, vilka ökar i täthet när temperaturen stiger under våren. Undersökningen gick ut på att märka fiskar och följa deras beteende under våren. Tanken var att få bekräftat att fiskarna undersöker födotillgången i sjön så länge tills födotillgången är så bra att vinsten de gör i tillväxt överväger farorna från predatorer i sjön. Undersökningen bekräftade att mörtar simmar fram och tillbaka mellan sjön och ån under en period med mer osäker fodertillgång innan alla till slut flyttar till sjön. Vid just den tidpunkten då födotillgången är tillräckligt stor för att kompensera för de förhöjda farorna av predatorer i sjön.

Le balbuzard pêcheur Pandion haliaetus est une espèce de rapace cosmopolite et migratrice mais menacée. C'est un modèle intéressant pour explorer comment les adaptations comportementales au sein de populations géographiquement distantes, ayant évoluées dans conditions écologiques différentes, pourraient être une cause proximale de leur distribution géographique et de différences génétiques et comportementales (stratégies migratrices et comportement de recherche alimentaire). Ainsi, j'ai mené une étude intégrative à différentes échelles afin de répondre à plusieurs questions fondamentales et appliquées.Grâce à une approche phylogéographique (phylogénie moléculaire) j'ai mis en évidence l'existence de quatre lignées différentes à l'échelle mondiale qui peuvent être considérées comme des Unités Evolutives Significatives (ESUs) et qui méritent des mesures de gestion spécifiques. En combinant des méthodes d'écologie moléculaire et d'observations d'oiseaux marqués, j'ai pu estimer le taux de connexion populationnelle dans le Paléarctique occidental. En combinant des outils d'écologie trophique en utilisant les isotopes stables, et d'écologie spatiale en utilisant de nouveaux outils en bio télémétrie, j'ai étudié les comportements migratoires et de l'écologie hivernale des balbuzards pêcheurs méditerranéens, que j'ai pu comparer avec ceux des populations nord européennes. Finalement, j'ai étudié la nécessité d'adopter des mesures de gestions adéquates pour trois population du bassin méditerranéen (Corse, Maroc, Italie), en comparant la dynamique des populations, en lien avec leurs ressources alimentaires (recensement des espèces piscicoles) et les perturbations d'origine anthropique. Dans l'ensemble, ce travail a conduit à des avancées significatives par rapport à la conservation des balbuzards pêcheurs à différentes échelles biogéographiques. Ces connaissances sont particulièrement utiles à l'égard d'une gestion efficace de cette espèce emblématique. / Being a cosmopolitan and migratory species, the osprey Pandion haliaetus provides a good opportunity to explore how behavioural adaptations in different populations, that evolved under different ecological conditions and are widely spaced, can be the proximate causes of geographical distribution, genetic divergence, population connectivity, migratory strategies and foraging ecology. According to this, a multi-scale integrated approach has been adopted for the osprey: through an interdisciplinary framework made by molecular ecology, trophic ecology as assessed via stable isotopic analyses, spatial ecology through the use of novel biotelemetry tools, as well as population dynamics, fish censuses and assessments of levels of human disturbance, we: a) evidenced the existence of four different lineages at global scale that should be treated as Evolutionary Significant Units (ESUs) and deserve specific management; b) revealed population connectivity in the Western Palearctic; c) disentangled the migratory behaviour and winter ecology of Mediterranean ospreys and compared it with northern European populations, in an evolutionary context; d) stressed the need of adequate management measures to be adopted for three local populations of the Mediterranean basin (Corsica, Morocco and Italy). Overall, this work has led to some important advances with respect to the conservation biogeography of ospreys at different scales. Those insights are particularly valuable with respect to the effective management of this emblematic species.

There has been a lot of work that has been done on timing predictability of real-time tasks on embedded systems. The main assumption in these studies has been that the timing behavior has been based on single processor systems. The scenario has changed entirely when the single core systems have been replaced with the new Multicore systems. The timing predictability is controlled by the migrating tasks, the network topology connecting the cores and the number of cores on the system. In this thesis we come up with a feasibility analysis which depends on the characteristics of the tasks viz. number of cache lines, time of migration, available bandwith, number of tasks etc. We also test this analysis on novel mechanisms of migration which have been proposed recently and present its results.
