Capability to route can be considered as one of the key features of a modern multipurpose operating system, which HelenOS aims to be. The goal of this master thesis is to explore current HelenOS routing capabilities, enhance them and empower HelenOS with BIRD. HelenOS will become a routing operating system with awareness of its surroundings. It will be capable of dynamic adaptation to changes in the network and their propagation.

The timing of biological events in autumn, or autumn phenology, is an important factor in many ecosystem processes. Leaf senescence terminates the growing season, fruiting is important for seed dispersal and frugivorous wildlife, bird migration concludes the breeding season and is a high-mortality event, and insect diapause ends the active season for insects. Climate change and the spread of invasive species have the potential to shift autumn events and ecological processes. However, autumn has been neglected in the phenology literature, and there are many gaps in our knowledge of basic phenological patterns in this season, as well as how they are affected by anthropogenic changes. To address these gaps, I first synthesized the literature on how climate change affects autumn phenology. I found that shifts in autumn phenology can alter reproductive capacities, exacerbate invasions, increase disease transmission rates, reshuffle enemy-prey dynamics, and alter interactions between species. With a focus on autumn interactions between birds and fleshy-fruited plants, my colleagues and I then observed patterns of fruit phenology, using herbarium specimens of 55 species collected across New England, and over 400 species in the living collections of 5 international botanical gardens. Last, I monitored fleshy fruit phenology and abundance at Manomet, a migratory stopover site in coastal Massachusetts, and compared those patterns to seeds identified from landbird fecal samples collected across the autumn season. I found that the sequence of fruiting is moderately consistent from year to year and place to place, and has a significant phylogenetic signal. In wild plants, invasive species fruit, on average, nearly one month later than native species. Considering many landbirds are migrating through New England later over time and in warm years, this suggests birds are increasingly likely to encounter invasive fruits during late-autumn migration. However, bird diets do not reflect the increased availability of invasive fruits in late-autumn; rather, birds show a preference for native fleshy fruits throughout the autumn season. These findings add to our knowledge of how climate change and species invasions affect autumn synchrony, and highlight the importance of native, rather than invasive, fruits as a food source for migratory landbirds. / 2019-11-07T00:00:00Z

Le métabolisme glucidique de l’oiseau est important pour maitriser la croissance de l’animal et la qualité de la viande. Nous avons étudié l’utilisation périphérique du glucose chez le poulet au niveau musculaire en identifiant et en caractérisant les principaux acteurs impliqués. Nous avons identifié et caractérisé un nouveau transporteur de glucose chez les oiseaux, GLUT12. Il est exprimé dans les muscles, son expression est régulée in vivo par l’insuline et il peut être enrichi dans les membranes plasmiques des cellules suite à une stimulation insulinique. In vitro, une augmentation du transport de glucose est mesurée sur le même pas de temps que la translocation de GLUT12. Comme pour GLUT4 chez les mammifères, la PI3K est impliquée dans la translocation de GLUT12. L’expression des GLUTs musculaires varie avec l’âge des animaux mais aussi avec leur état physiologique, le type métabolique et/ou la fonction du muscle. L’ensemble de nos résultats explique en partie le métabolisme glucidique atypique des oiseaux et laisse entrevoir le développement de nouvelles stratégies d’élevage pour répondre à une demande croissante de produits avicoles de qualité. / Glucose metabolism in birds is important to control animal growth and meat quality. We studied peripheral glucose utilization in chicken muscle by identifying and characterizing a new glucose transporter in birds, GLUT12. This transporter is expressed in muscles, its expression is regulated in vivo by insulin and it can be enriched in cells plasma membranes following insulin stimulation. In vitro an increase of glucose transport is measured in the same time than GLUT12 translocation. As for GLUT4 in mammals, PI3K pathway is involved in GLUT12 translocation. Expression of muscular GLUTs varies depending on animals’ age but also depending on their physiological state and on the metabolic type and/or function on the muscle. All of our results partly explain the atypical glucose metabolism in birds and let us foresee development of new farming strategies in order to answer to increased demand of avian quality products.

Pesticides, rat control or targeted placed, poisoning bait by carbofuran. These and many other ways can cause the poisoning of a wild animal. Whether targeted poiso-ning of a particular animal poison or unintentional poisoning of a non-target individu-al occurs, this behavior has always fatal consequences. The persecution of nuisance animals, such as Foxes, Martens or other predators, has an influence on the whole of the population. Often poisoning bird of prey is a White-tailed Eagle, in which case every poisoned individual has an impact on the whole of the population. Unfortu-nately, this made bait is poisoning far more animals, especially for scavengers and carnivores. This paper explores the available data of poisoning animals and maps their occurrence. The data was obtained from the database the Animal Rescue Centre and the Free Wings in the period 2009-2016. Among the most commonly accepted ani-mals in the stations was the Roe Deer with poisoning caused by the Rape. Water-borne birds were Often bothered by botulism, followed by individual poisoning with poison on the rodent and poison on the Slugs. Carbofuran was most poisoned by the White-tailed Eagle, the Common Buzzard, and the Common Raven. Among the poi-sonous species are also the endangered the Red Kite, the Black Kite, and the Golden Eagle. Furthermore, it has been found that individual years have no effect on poison-ing. The difference in the number of birds and mammals poisoning was not detected. The influence of the month on the data obtained from stations was not found, the number of carbofuran poisoning is higher in March, and especially in April. In the analysis of spatial differences, there is also a balance between most regions. The Cen-tral Bohemian and the South Bohemian regions are markedly different. Above-average numbers of carbofuran poisoning originate in the regions of the South Bohe-mia, the Vysočina, the South Moravian and the Ústecký region.
