description |
Metabolic rates are an important physiological metric because they serve as proxies for the energy that organisms need to survive. Metabolic rates are affected by intrinsic characteristics of organisms and by environmental factors. For instance, diet may affect metabolic rates due to differences in energy contents and digestibility of food items. Here we assess whether metabolic rates are associated with diet in Neotropical birds. Between June 2017 and November 2018, we measured three components of metabolic rates (basal, maximum, and aerobic scope) for 118 individuals from 28 species in three localities in Valle del Cauca, Colombia located in lowlands (800 m and 1000 m) and highlands (2400 m). For each species, we also obtained the percentage of fruit and invertebrates in their diets from the literature. We used phylogenetically corrected linear models to examine relations between diet, metabolic rates, and elevation. We found that birds from higher elevations had higher metabolic rates than those from lower elevations. Also, basal metabolic rate (at all elevations), as well as maximum metabolic rate and aerobic scope in lower elevations, were lower in species that eat more fruit. Maximum metabolic rate and aerobic scope in high elevations did not vary with diet. These patterns may be related with compound digestibility, absorption of energy, and the different challenges of living at high elevations (e.g thermoregulation). Our study helps to understand different ecological factors that affect the physiology of Neotropical birds, and the importance of energetic constraints for different life- history traits in birds. |

La tasa metabólica es afectada tanto por características intrínsecas del organismo como por factores externos. Por ejemplo, la dieta podría afectar las tasas metabólicas debido a diferencias en el contenido energético y la digestibilidad de los tipos de dieta. En este estudio nos preguntamos si las tasas metabólicas están asociadas con la dieta en aves neotropicales. Entre junio de 2017 y noviembre de 2018 hicimos mediciones de tres componentes de las tasas metabólicas (basal, máxima y el alcance aeróbico) para 118 aves de 28 especies en tres localidades del Valle del Cauca, Colombia localizadas en bajas elevaciones (800m y 1000m) y altas elevaciones (2400m). Para cada especie, obtuvimos de la literatura el porcentaje de frutas e invertebrados en la dieta. Utilizamos modelos lineales corregidos filogenéticamente para examinar las relaciones entre la dieta, las tasas metabólicas y la elevación. Encontramos que las aves de elevaciones altas tienen tasas metabólicas más altas que las de zonas bajas. Además, la tasa metabólica basal (en todas las elevaciones), así como la tasa metabólica máxima y el alcance aeróbico en elevaciones más bajas, fueron más bajas en las especies que se alimentan más de fruta. La tasa metabólica máxima y el alcance aeróbico en altas elevaciones no variaron con la dieta. Estos patrones pueden estar relacionados con la digestibilidad de los compuestos, la absorción de energía y los diferentes desafíos de vivir a grandes elevaciones (por ejemplo, termorregulación). Nuestro estudio ayuda a comprender los diferentes factores ecológicos que afectan la fisiología de las aves neotropicales y la importancia de las limitaciones energéticas para los diferentes rasgos de la historia de vida de las aves.BiólogoPregrado25 hojasapplication/pdfengUniversidad de los AndesBiologíaFacultad de CienciasDepartamento de Biologíainstname:Universidad de los Andesreponame:Repositorio Institucional SénecaDiet influences metabolic rates in neotropical birdsTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesishttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TPEcología de las avesAvesOrnitologíaBiologíaPublicationORIGINALu833723.pdfapplication/pdf1049677https://repositorio.uniandes.edu.co/bitstreams/8a06d572-ebac-4a96-b414-0a0a37f5a1af/download38c95e3149663e83b26ac27a2233c4c4MD51TEXTu833723.pdf.txtu833723.pdf.txtExtracted texttext/plain39464https://repositorio.uniandes.edu.co/bitstreams/bf03e2ec-0d77-4ee0-9e9f-70ca5fd591a8/download15c508e7355380ae05c51085003e0fbcMD54THUMBNAILu833723.pdf.jpgu833723.pdf.jpgIM Thumbnailimage/jpeg7326https://repositorio.uniandes.edu.co/bitstreams/d003c32b-c5f0-4a6a-9a72-29b869ff724c/downloadfa098b0b84f16290ba507401a8a87037MD551992/49024oai:repositorio.uniandes.edu.co:1992/490242023-10-10 17:20:28.733http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |
