Physiological indices of stress in wild and captive garter snakes: correlations, repeatability, and ecological variation
(Elsevier, 2014)
Glucocorticoids and leukocyte ratios have become the most widespread variables employed to test hypotheses regarding physiological stress in wild and captive vertebrates. Little is known, however, regarding how these two ...
Insulin-like signaling (IIS) responses to temperature, genetic background, and growth variation in garter snakes with divergent life histories
(Academic Press Inc Elsevier Science, 2016-07-01)
The insulin/insulin-like signaling pathway (IIS) has been shown to mediate life history trade-offs in mammalian model organisms, but the function of this pathway in wild and non-mammalian organisms is understudied. Populations ...
Corticosterone and pace of life in two life-history ecotypes of the garter snake thamnophis elegans
(Academic Press Inc Elsevier Science, 2012-02)
Glucocorticoids are main candidates for mediating life-history trade-offs by regulating the balance between current reproduction and survival. It has been proposed that slow-living organisms should show higher stress-induced ...
Immune variation during pregnancy suggests immune component-specific costs of reproduction in a viviparous snake with disparate life-history strategies.
(Wiley-liss, Div John Wiley & Sons Inc, 2017-12)
Growing evidence suggests the existence of trade-offs between immune function and reproduction in diverse taxa. Among vertebrates, however, there is still a taxonomic bias toward studies in endotherms, particularly birds. ...
Genetic background and thermal environment differentially influence the ontogeny of immune components during early life in an ectothermic vertebrate
(Wiley Blackwell Publishing, Inc, 2020-05)
1.An understudied aspect of vertebrate ecoimmunology has been the relative contributions of environmental factors (E), genetic background (G) and their interaction (G × E) in shaping immune development and function. ...
Complex Interplay of Body Condition, Life History, and Prevailing Environment Shapes Immune Defenses of Garter Snakes in the Wild
(University of Chicago Press, 2013-08-14)
The immunocompetence “pace-of-life” hypothesis proposes that fast-living organisms should invest more in innate immune defenses and less in adaptive defenses compared to slow-living ones. We found some support for this ...
Influencia de la temperatura en el comportamiento alimentario de peltocephalus dumerilianus (testudines podocnemidae)
(Universidad de Córdoba, 2009)
Análisis de relaciones biológicas en el modelo hemoparásito-quelonios en Colombia
(Universidad Nacional de ColombiaBogotá - Medicina - Maestría en Infecciones y Salud en el TrópicoDepartamento de Salud PúblicaFacultad de MedicinaUniversidad Nacional de Colombia - Sede Bogotá, 2021-10-01)
Algunos géneros de parásitos del suborden Adeleorina infectan usualmente hospederos intermediarios como las tortugas. Sin embargo, el conocimiento que se tiene acerca de las especies de parásitos que infectan estos hospederos ...
Identificación de hemoparásitos presentes en la herpetofauna de diferentes departamentos de Colombia
(Instituto de BiotecnologíaUniversidad Nacional de Colombia - Sede Bogotá, 2019-11-14)
Colombia es un país altamente diverso en flora y fauna, siendo el 4to país con mayor biodiversidad de reptiles en el mundo. Sin embargo, los estudios relacionados con parásitos sanguíneos que infectan animales ...
