Abstract:
In the domain of UAVs, endurance and range are key utility factors. However, small-sized UAVs are faced with serious limitations regarding energy storage options. A way to address this challenge is to seek for energy from the surrounding environment. One flight technique, called dynamic soaring, has been perfected by large seabirds like the albatross, which enables them to wander effortlessly in southern oceans. This thesis investigates the feasibility to find inspiration from the biological world in order to address the issue of limited endurance. First of all, an extensive literature backgro

Abstract:
Most albatrosses are critically endangered, endangered or vulnerable due to the deleterious impact of fisheries, pollution, introduced species, habitat alteration, and climate change. Foraging behaviour influences many aspects of seabird biology, and a detailed understanding of foraging ecology is required to better predict the impacts of significant changes to the marine environment. Campbell Albatross (Thalassarche impavida) is a threatened endemic, confined to a small number of locations on Campbell Island, New Zealand and was recently split from the closely related Black-browed Albatross (

Abstract:
Dynamic soaring is an engineless flight technique, which extracts energy from a wind gradient. i.e. a change in wind speed with height. It is the key method by which albatrosses achieve their long endurance flight of several thousand miles, flown with hardly a flap of their wings. Such flying takes the albatross close to the water's surface and usually occurs in strong wind conditions. Development of unmanned aerial vehicles (DAVs) is driven by the need of long endurance flight. Techniques such as increasing the engine's fuel efficiency and increasing the amount of fuel carried on-board, suffe

Age-related variation in demographic rates has significant consequences for population and evolutionary dynamics, and understanding the processes driving such variation is therefore an important aspect of evolutionary ecology. Reproductive performance may vary over the lifetime of an individual, and this may be the result of both variations in reproductive effort and changes in individual competency. For example, increasing experience is likely to have beneficial effects on reproduction during early life, and senescence, or declines in physiological function, may have negative impacts on the p

L’océan Austral est soumis à la redistribution globale des contaminants par les voies atmosphérique et océanique. Cependant, la contamination des écosystèmes austraux est très peu connue, en particulier dans le secteur Indien. De par leur toxicité, leur mobilité et leur capacité à se bioaccumuler dans les tissus des organismes et à se bioamplifier dans les réseaux trophiques, le mercure (Hg) et les polluants organiques persistants (POPs) comptent parmi les contaminants les plus préoccupants. Du fait de leur position élevée dans les réseaux trophiques, les oiseaux marins sont exposés à de grand

Abstract:
Moult is an energetically demanding process for birds, and the replacement of flight feathers impacts flight performance. As a result, few birds overlap moult with other key activities such as breeding or migrating. Feather growth rates show little change in relation to body size, so large birds with long flight feathers take a long time to grow individual feathers, making their moult even more challenging. Unless these birds can afford to become flightless for several weeks while they replace all their flight feathers simultaneously, many large birds lack sufficient time to breed and replace

Cette thèse étudie les effets liés à l'âge et plus particulièrement liés à la sénescence chez deux espèces extrêmement longévives: l'albatros à sourcils noirs (Thalassarche melanophrys) et le grand albatros (Diomedea exulans). Dans un premier temps nous cherchons à déterminer quelles sont les variations de différents traits d'histoire de vie, démographiques et morphologiques en fonction de l'âge. Une approche multi-traits et multi-états nous permet de modéliser les variations des traits avec l'âge en prenant en compte les effets liés au sexe ou au statut reproducteur de l'année précédente dans

Abstract:
Seabird populations breeding within the Southern Ocean have experienced various threats over the past few decades. Albatrosses are particularly at risk due to several factors, inter alia, accidental bycatch on fishing gear, ingestion of polluted marine debris, invasive predatory species at breeding sites, as well as climate change-induced alterations to ocean circulation patterns. The recent decline in many albatross populations is mainly attributed to incidental fishing mortality, which decreases adult as well as juvenile survival rates and is thus detrimental to these long-lived, low fecundi

Abstract:
Cette thèse s'attache à expliquer les relations entre les variations de l'environnement et les populations de Procellariiformes (albatros et pétrels) du sud de l'Océan Indien, en étudiant leurs stratégies d'exploitations et d'allocation des ressources. Dans ce système, la recherche alimentaire est fortement contrainte par deux facteurs : le milieu présente une distribution des ressources avec une structure très hétérogène et morcelée (en "patch") et les oiseaux doivent faire durant la reproduction des allers-retours entre les zones d'alimentation et les sites de nidification sur parfois plusie

Abstract:
Le stade juvénile chez les animaux demeure souvent une période mystérieuse aux yeux des scientifiques. La survie juvénile est pourtant un facteur déterminant du futur des populations. Les animaux juvéniles sont connus pour leur mortalité importante durant les premiers mois après l’indépendance et leur taux de survie augmente avec l’âge. La théorie suppose d’une part que les juvéniles ont des capacités de survie moindres que celles des adultes. Ils seraient peu efficaces dans leur recherche de nourriture et auraient besoin d’une période d’apprentissage pour être capables de supporter les couts

This study analyses the presence of more-than-human beings, particularly animal figurations, in two works of diverse literary genres, namely: the poem “The albatross”(1861) by Charles Baudelaire and the short story “The house of Asterion”(1947) by Jorge Luis Borges through the lens of theories on the animal turn. Previous studies on both the poem and the short story analyzed the animal (albatross and minotaur) in allegorical or metaphorical terms emphasizing a human-centered perspective.However, this study maps an encounter between voice (human and hybrid) and the more-than-human being beyond

Abstract:
Two sympatric Phoebetria albatrosses, P. fusca and palpebrata breeding at Marion Island in the South Indian Ocean were studied. Adult individuals were tracked between 2008 and 2011. The study examined the foraging distribution of the two species in relation to environmental parameters such as sea surface temperature. Interaction with mesoscale features expressed by sea surface temperatures, was tested with statistical models. Tracked P. fusca demonstrated positive association with sea surface temperatures in the Southern Indian Ocean, in particular during incubating and chick-provisioning peri
