Alternative hypotheses have been proposed regarding how the hormone corticosterone (CORT) mediates energy expenditure during reproduction. Elevated baseline CORT (CORTb) could support daily energy expenditure (DEE), promoting reproductive effort or downregulate costly behaviours in low quality individuals facing allostatic overload.We investigated relationships between CORTb, time activity budgets (TABs), DEE and diving behaviour across 2 years and colonies of little auk (Alle alle), an Arctic seabird in which elevating DEE may support reproduction in the face of climate change.We also explored whether mercury (Hg) contamination might suppress DEE by affecting the hypothalamus‐pituitary–adrenal (HPA) axis and CORT production.Furthermore, we performed phylogenetically controlled analysis across breeding seabird species to build broader understanding of CORT‐DEE relationships.CORTb positively correlated with little auk activity, DEE and dive duration during a cold year in East Greenland, when CORTb was elevated in the population, but not during a warmer year, or at Svalbard. CORTb did not predict chick provisioning nor did Hg suppress CORTb.Across breeding seabird species, CORTb and DEE were uncorrelated. Rather, contrary to predictions, CORTb was higher in species breeding at lower latitudes.Intraspecific results suggest environment‐dependent relationships between CORTb, behaviour and DEE, with implications for understanding CORTb's role in climate change resiliency.Interspecific analyses suggest absence of correlational selection between CORTb and DEE during reproduction, and that DEE thresholds that induce changes in CORTb might differ between species.

- Abstract
Aim: Over the last decades, the study of movement through tracking data has grown exceeding the expectations of movement ecologists. This has posed new challenges, specifically when using individual tracking data to infer higher- level distributions (e.g. population and species). Sources of variability such as individual site fidelity (ISF), en-vironmental stochasticity over time, and space-use variability across species ranges must be considered, and their effects identified and corrected, to produce accurate estimates of spatial distribution using tracking data. Innovation: We developed R functions to detect the effect of these sources of vari-ability in the distribution of animal groups when inferred from individual tracking data. These procedures can be adapted for their use in most tracking datasets and tracking techniques. We demonstrated our procedures with simulated datasets and showed their applicability on a real-world dataset containing 1346 year- round migratory trips from 805 individuals of three closely related seabird species breeding in 34 colonies in the Mediterranean Sea and the Atlantic Ocean, spanning 10 years. We detected an effect of ISF in one of the colonies, but no effect of the environmental stochasticity on the distribution of birds for any of the species. We also identified among-colony variability in nonbreeding space use for one species, with significant effects of popu-lation size and longitude. Main conclusions: This work provides a useful, much- needed tool for researchers using animal tracking data to model species distributions or establish conservation measures. This methodology may be applied in studies using individual tracking data to accurately infer the distribution of a population or species and support the deline-ation of important areas for conservation based on tracking data. This step, designed to precede any analysis, has become increasingly relevant with the proliferation of studies using large tracking datasets that h

- Abstract
Migratory marine species cross political borders and enter the high seas, where the lack of an effective global management framework for biodiversity leaves them vulnerable to threats. Here, we combine 10,108 tracks from 5775 individual birds at 87 sites with data on breeding population sizes to estimate the relative year-round importance of national jurisdictions and high seas areas for 39 species of albatrosses and large petrels. Populations from every country made extensive use of the high seas, indicating the stake each country has in the management of biodiversity in international waters. We quantified the links among national populations of these threatened seabirds and the regional fisheries management organizations (RFMOs) which regulate fishing in the high seas. This work makes explicit the relative responsibilities that each country and RFMO has for the management of shared biodiversity, providing invaluable information for the conservation and management of migratory species in the marine realm.

- Abstract
The conservation of migratory marine species, including pelagic seabirds, is challenging because their movements span vast distances frequently beyond national jurisdictions. Here, we aim to identify important aggregations of seabirds in the North Atlantic to inform ongoing regional conservation efforts. Using tracking, phenology, and population data, we mapped the abundance and diversity of 21 seabird species. This revealed a major hotspot associated with a discrete area of the subpolar frontal zone, used annually by 2.9–5 million seabirds from ≥56 colonies in the Atlantic: the first time this magnitude of seabird concentrations has been documented in the high seas. The hotspot is temporally stable and amenable to site-based conservation and is under consideration as a marine protected area by the OSPAR Commission. Protection could help mitigate current and future threats facing species in the area. Overall, our approach provides an exemplar data-driven pathway for future conservation efforts on the high seas.

- Abstract
Migratory marine species cross political borders and enter the high seas, where the lack of an effective global management framework for biodiversity leaves them vulnerable to threats. Here, we combine 10,108 tracks from 5775 individual birds at 87 sites with data on breeding population sizes to estimate the relative year-round importance of national jurisdictions and high seas areas for 39 species of albatrosses and large petrels. Populations from every country made extensive use of the high seas, indicating the stake each country has in the management of biodiversity in international waters. We quantified the links among national populations of these threatened seabirds and the regional fisheries management organizations (RFMOs) which regulate fishing in the high seas. This work makes explicit the relative responsibilities that each country and RFMO has for the management of shared biodiversity, providing invaluable information for the conservation and management of migratory species in the marine realm.

[spa] Los océanos están sufriendo un cambio muy rápido. Esto evidencia la necesidad de estudiar especies a largo plazo que puedan informarnos sobre la magnitud y dirección de estos cambios. Los ambientes oceánicos son especialmente difíciles de estudiar, por lo que profundizar en la estrategia de vida de un depredador oceánico podría aportar luz sobre los vínculos entre el medio oceánico, los recursos tróficos y cómo estos son usados para supervivencia, crecimiento y fecundidad. Estas cuestiones pueden ser estudiadas a través de diferentes disciplinas, como la demografía, el movimiento animal o la ecología trófica, cuyos rápidos avances tecnológicos y teóricos han abierto nuevas posibilidades de investigación. Las mejoras en los modelos de captura-marcaje-recaptura, el aumento en el uso de análisis de isótopos estables en estudios de dieta y migración, junto con la reducción del tamaño de los dispositivos de seguimiento remoto, ofrecen la oportunidad de estudiar las estrategias de vida de especies pequeñas hasta ahora inaccesibles. Con la presente tesis, mi objetivo es estudiar la estrategia de vida de una especie pequeña, longeva, oceánica y migratoria, el petrel de Bulwer (Bulweria Bulwerii), en el océano Atlántico. Específicamente, mi objetivo es profundizar en las estrategias de alimentación y migratorias, y entender las implicaciones de la reproducción en su ecología trófica y su supervivencia. Mis resultados revelan que, durante el periodo de cría, los petreles de Bulwer buscan alimento principalmente alrededor de las Islas Canarias y las aguas de Azores, donde se alimentan de presas mesopelágicas. Muestro cómo la reproducción implica limitaciones (a nivel espacial, de actividad y trófico) y cómo puede suponer un coste en la supervivencia, especialmente para las hembras de petrel de Bulwer, mientras que los machos parecen reducir este coste mediante la toma de años sabáticos. Evalué y confirmé el potencial del análisis de isótopos estables como un buen marcador geográfico para el estudio de los movimientos migratorios de depredadores marinos. Los petreles de Bulwer migraron a dos áreas principales de invernada, el Atlántico Central y Sur, lo que implica diferencias en fenología y en las estrategias migratorias. Los petreles de Bulwer parecen ser resilientes a los cambios en el medio durante la invernada, pero más sensibles a ellos durante la época de cría, resultando en una menor supervivencia en años con mayor temperatura de la superficie del mar. De hecho, inferí que la creciente temperatura de los océanos disminuirá drásticamente la supervivencia del petrel de Bulwer, comprometiendo la viabilidad de sus poblaciones, y convirtiendo esta especie en un excelente centinela de los cambios que ocurren en las redes tróficas oceánicas., [eng] Oceans are suffering from rapid environmental change, pointing to the need of multi-year studies on species that can inform us about the strength and direction of these changes. Oceanic environments are remarkably difficult to study, thus studying the Life History (LH) strategy of an oceanic predator may shed new light on the links between the oceanic environment, trophic resources and how these are used for survival, growth, and fecundity. These topics can be studied through different disciplines, such as demography, movement and trophic ecology, for which rapid technological and theoretical advances have opened new avenues of research. The improvements in capture-mark-recapture models, the increasing use of stable isotopes analysis (SIA) in diet and migration studies, together with the size reduction in tracking devices, offer the opportunity to study LH strategies of small species previously inaccessible. With the present thesis, I aimed to study the LH strategy of a small, long-lived, oceanic and migratory species, the Bulwer’s petrel (Bulweria bulwerii; BP), in the Atlantic Ocean. Specifically, I aimed to delve into their foraging and migratory strategies and to understand the implications of reproduction on their trophic ecology and survival. Our results revealed that during the breeding period BP foraged mainly around the Canarian and Azorean waters to feed on mesopelagic prey. I showed that reproduction implies constraints (at spatial, activity, and trophic levels) and can carry a cost on survival, especially for BP females, while males seem to reduce this cost through sabbatical years. We evaluated and confirmed the potential of SIA as a good geographic marker to study migratory movements of marine predators. BP migrated to two main non-breeding areas, the Central and the South Atlantic, which implied different phenological and migratory strategies. BP showed to be resilient to environment changes during the non-breeding season, but more sensitive to them during the breeding season, resulting in a lower survival in years with higher sea surface temperature. Indeed, we inferred the increasing temperature of the oceans will sharply decrease BP survival, compromising their populations viability, and making them an excellent sentinel of the changes occurring in oceanic food webs.

Studying the movements of oceanic migrants has been elusive until the advent of several tracking devices, such as the light-level geolocators. Stable isotope analysis (SIA) offers a complementary approach to infer areas used year-round, but its suitability in oceanic environments remains almost unexplored. To evaluate SIA as a tool for inferring movements of oceanic migrants, we sampled an oceanic seabird, the Bulwer's petrel, Bulweria bulwerii, in four breeding colonies spread along its Atlantic distribution. We first studied the species moulting pattern from 29 corpses collected in the colonies. Secondly, based on this moult knowledge, we selected three feathers from tracked birds to infer their breeding and non-breeding grounds using SIA: the 1st primary (P1), the 8th secondary (S8) and the 6th rectrix (R6) feathers. Birds migrated to two main non-breeding areas, the Central or the South Atlantic Ocean. P1 showed similar isotopic values among petrels from different breeding colonies, suggesting this feather is replaced early in the non-breeding period in a common area used by most birds, the Central Atlantic. S8 and R6 feathers correctly assigned 92% and 81%, respectively, of the birds to their non-breeding areas, suggesting they were replaced late in season, when birds were settled in their main non-breeding grounds. Our results showed that the isotopic baseline levels of the Central and South Atlantic are propagated through the food web until reaching top predators, suggesting these ratios can be used to infer the movement of long-distance migrants among oceanic water masses.

- Abstract
Using geolocator-immersion loggers, we tracked for the first time the migration of one Cory's Shearwater Calonectris borealis fledgling, from its breeding colony in the Canary Islands, and along its first year of life. The juvenile bird initially followed the same migratory path as the adults but visited different areas of the Central and the South Atlantic Ocean. [ABSTRACT FROM AUTHOR]
