| description |
Understanding the role of climatic factors on diversification processes remains among the pivotal questions in ecology and evolutionary biology. The main goal of this study was to approach this question at different temporal and spatial scales within a convenient model: the egg-feeding poison frogs in the genus Oophaga and their relatives. I first constructed a phylogeographic hypothesis on the evolution of Oophaga pumilio lineage. Phylogeographic analysis suggest that the Nicaraguan populations originated by a Late Pleistocene range expansion northwards, and reconstructs the origin of the species in southeastem Costa Rica. I investigated geographic variation in physiological traits linked to the regulation of evaporative water loss and tested for correlations with current and past climatic heterogeneity |

El objetivo principal de este estudio fue abordar esta pregunta a diferentes escalas temporales y espaciales en un modelo convencional: las ranitas comedoras de huevos del género Oophaga y sus parientes. Inicialmente reconstruí una hipótesis filogeográfica acerca de la evolución de Oophaga pumilio incluyendo poblaciones de Nicaragua no incluidas en estudios preliminares. Los análisis filogeográficos sugieren que estas poblaciones se originaron a través de la expansión de su rango de distribución al norte durante el Pleistoceno tardío y reconstruyen el origen de la especie en el suroccidente de Costa Rica. Posteriormente investigué la variación geográfica en rasgos fisiológicos relacionados con la regulación de pérdida de agua por evapotranspiración y puse a prueba correlaciones entre estos rasgos fisiológicos con las condiciones de heterogeneidad climática temporalDoctor en Ciencias - BiologíaDoctorado125 hojasapplication/pdfengUniandesDoctorado en Ciencias - BiologíaFacultad de CienciasDepartamento de Biologíainstname:Universidad de los Andesreponame:Repositorio Institucional SénecaUnraveling the contribution of climatic heterogeneity on evolutionary processes within oophaga poison dart frogsTrabajo 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/TDRanas - InvestigacionesDendrobatidae - InvestigacionesBiologíaPublicationhttps://scholar.google.es/citations?user=07uD4yoAAAAJvirtual::9784-1https://scholar.google.es/citations?user=RRatlj4AAAAJvirtual::9785-10000-0001-7320-1143virtual::9784-10000-0001-8089-4056virtual::9785-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000111082virtual::9784-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000211010virtual::9785-140c7a2f6-d55d-4787-a6a1-07644bbc435cvirtual::9784-19026322f-770f-4c0a-b50f-78c4a32b9f06virtual::9785-140c7a2f6-d55d-4787-a6a1-07644bbc435cvirtual::9784-19026322f-770f-4c0a-b50f-78c4a32b9f06virtual::9785-1ORIGINALu754002.pdfapplication/pdf5349300https://repositorio.uniandes.edu.co/bitstreams/d444e0bb-3e81-47b9-a4da-ea2d4524a71f/download5dd54c6ccc1d0b9d808f4735a95985d2MD51THUMBNAILu754002.pdf.jpgu754002.pdf.jpgIM Thumbnailimage/jpeg10276https://repositorio.uniandes.edu.co/bitstreams/5e3a9cf8-54f4-4869-94c9-85f9d8d32a5f/downloadc0acd8a3978e63ddb3701c6345cd1c2cMD57TEXTu754002.pdf.txtu754002.pdf.txtExtracted texttext/plain206491https://repositorio.uniandes.edu.co/bitstreams/98a18679-da80-4af7-8859-fe1ef582bbef/download7d99cdfd2ca9169eb8f5f5892c1f7b74MD561992/7733oai:repositorio.uniandes.edu.co:1992/77332024-08-26 15:23:56.864http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |
