description |
Migration results in predictable, seasonal movements of millions of animals across the globe. Not only is migration an impressive natural phenomenon, but it is involved in ecological and evolutionary processes ranging from determining individual fitness and population dynamics, to influencing speciation and ecosystem functioning. All events in the annual cycle of migrants are intricately linked. One event which has been shown to significantly affect population dynamics, is migration. The strategies birds use to optimize their movements are known as migratory strategies. Depending on body condition, age, sex, date, weather, distance to destination and evolutionary constraints, birds may choose to fly directly or make few stops along the way. How birds carry out this optimization of their migratory strategies is not well understood and likely varies in different species. By studying bird migration with the use behavioral observations, capture-recapture, intercontinental telemetry, stable isotopes and genetics, I generated information about the evolution of migratory strategies, how different biotic and abiotic factors affect them, how flexible these strategies appear in the face of climatic or habitat changes and the implications this may have on migratory species conservation. My thesis is divided into four chapters. Chapter 1 proposes a method for the assessment of seasonal changes in animal diets, and an evaluation of the importance of diet during migration. Chapter 2 integrates behavioral data with remote tracking to understand how birds behave during stopover and to quantify the effect of a stopover on the pace of migration. Chapter 3 explores how a migratory bird links two of the planet's greatest forests, the Amazon and the Boreal, via the world's most irreplaceable natural region and center of endemism, the Sierra Nevada de Santa Marta. Finally, Chapter 4 evaluates the temporal dynamics of climatic niche evolution and its relation to migratory behavior |

No solo es un fenómeno natural impresionante, pero influye en procesos ecológicos y evolutivos desde la determinación del desempeño individual y las dinámicas poblacionales, hasta la especiación y el funcionamiento de ecosistemas. Todos los eventos en el ciclo anual de las especies migratorias están ligados. Un evento que afecta las dinámicas poblacionales es la migración. Las estrategias que las aves utiliza para optimizar sus movimientos se conocen como estrategias migratorias. Dependiendo de la condición física, edad, sexo, fecha, clima, distancia a recorrer y limitaciones evolutivas, las aves pueden escoger hacer vuelos directos o varias paradas en el camino. Cómo las aves optimizan sus estrategias migratorias no se conoce bien y probablemente varía en diferentes especies. Estudiando la migración por medio de observaciones, captura-recaptura, telemetría intercontinental, isótopos estables y genética, generé información sobre la evolución de las estrategias migratorias, cómo factores bióticos y abióticos las afectan, qué tan flexibles son al cambio climático y de hábitat, y las implicaciones de todo esto en la conservación de las aves migratorias. La tesis se divide en 4 capítulos. El Capítulo 1 propone un método para evaluar cambios estacionales en la dieta de aves, y explora la importancia de la dieta durante la migración. El Capítulo 2 integra datos de comportamiento con telemetría para entender cómo las aves se comportan durante las paradas migratorias y cuantificar el efecto de una parada en la velocidad de la migración. El Capítulo 3 explora cómo un ave conecta el bosque boreal con la Amazonía y con la Sierra Nevada de Santa Marta. Finalmente, el Capítulo 4 evalúa la dinámica temporal en la evolución de los nichos climáticos y su relación con la migración."--Tomado del Formato de Documento de GradoDoctor en Ciencias - BiologíaDoctorado111 hojasapplication/pdfspaUniandesDoctorado en Ciencias - BiologíaFacultad de CienciasDepartamento de Biologíainstname:Universidad de los Andesreponame:Repositorio Institucional SénecaEcological and evolutionary processes that shape the long-distance migrations of birdsTrabajo de grado - Doctoradoinfo:eu-repo/semantics/doctoralThesishttp://purl.org/coar/resource_type/c_db06http://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TDAves migratorias - Dieta - InvestigacionesAves migratorias - Hábitos alimenticios - InvestigacionesAves migratorias - Telemetría - InvestigacionesAves migratorias - Hábitos y conducta - InvestigacionesNicho (Ecología) - Investigaciones - Amazonía (Región, Colombia) - Estudio de casosNicho (Ecología) - Investigaciones - Sierra Nevada de Santa Marta (Colombia) - Estudio de casosBiologíaPublicationTEXTu807153.pdf.txtu807153.pdf.txtExtracted texttext/plain302627https://repositorio.uniandes.edu.co/bitstreams/a19fdd46-e8c5-44b4-ba34-4be79803b9be/download4425fed5957f20a5b2654e44a5f71d47MD56THUMBNAILu807153.pdf.jpgu807153.pdf.jpgIM Thumbnailimage/jpeg9931https://repositorio.uniandes.edu.co/bitstreams/a78a8970-e351-4e48-9a9a-d5c8556e5fef/download092213dea7bc2110d5e63aead270d32aMD57ORIGINALu807153.pdfapplication/pdf9305295https://repositorio.uniandes.edu.co/bitstreams/8c1c7c15-aa71-41d8-ad9c-d75ddd951347/downloade5b796cf31aa0fb94539959c32332546MD511992/38677oai:repositorio.uniandes.edu.co:1992/386772024-08-26 15:24:26.42http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |
