Comparison of body temperature and heart rate in sea turtles from Baja California Sur, Mexico
Sea turtles depend on ambient temperature to carry out their main activities, so changes in water temperature can affect the function of their immune system and represent different threats. To assess vital signs in black sea turtles (Chelonia mydas) in the Ojo de Liebre lagoon complex, Mexico, 600 t...

| description |
Sea turtles depend on ambient temperature to carry out their main activities, so changes in water temperature can affect the function of their immune system and represent different threats. To assess vital signs in black sea turtles (Chelonia mydas) in the Ojo de Liebre lagoon complex, Mexico, 600 turtles were examined. Carapace, plastron, and left inguinal area temperatures were measured with a digital infrared thermometer gun. Cloacal temperature was measured with an electronic thermometer. Heart rate was recorded using a stethoscope. Statistical analyses found no significant variation between inguinal area and cloacal temperatures. Vital sign measurements were compared with previous reports in the region, and there were differences in body temperatures, which were attributed to the characteristics of the water masses inhabited by the turtles. There was no significant difference between heart rate data for black sea turtles in this study and previously reported data for healthy sea turtles in the region, indicating that these data are likely an accurate representation for the species. All values fell within the reference intervals for healthy sea turtles. This minimally invasive diagnostic approach using vital signs allowed us to evaluate and infer core organ functions and to rule out health threats such as cold-stunning, resulting in a useful preliminary systemic assessment of free-ranging sea turtles. |

Las tortugas marinas dependen de la temperatura ambiental para llevar a cabo sus actividades principales, por lo que los cambios en la temperatura del agua pueden afectar la función de su sistema inmunológico y representar diferentes amenazas. Para evaluar los signos vitales de las tortugas negras (Chelonia mydas) del complejo lagunar Ojo de Liebre, México, se examinaron 600 tortugas. Las temperaturas de caparazón, plastrón y área inguinal izquierda se midieron con un termómetro digital infrarrojo. La temperatura cloacal se midió con un termómetro electrónico. La frecuencia cardíaca se registró con un estetoscopio. No se encontraron diferencias significativas entre las temperaturas del área inguinal izquierda y cloacales. Los valores de los signos vitales se compararon con reportes previos en la región, y hubo diferencias en las temperaturas corporales, las cuales fueron atribuidas a las características de las masas de agua en las que habitan las tortugas. No hubo diferencias significativas entre datos de frecuencia cardíaca de las tortugas negras de este estudio y los datos reportados previamente para tortugas marinas sanas en la región, lo cual sugiere que estos datos son una representación precisa de las especies. Todos los valores estuvieron dentro de los intervalos de referencia para tortugas marinas sanas. Este enfoque diagnóstico mínimamente invasivo por medio de signos vitales nos permitió evaluar e inferir funciones fisiológicas centrales básicas y descartar amenazas como frío paralizante, lo cual resulta útil como evaluación sistémica inicial de tortugas marinas en vida libre. 2021-06-02 2021-06-03T03:55:48Z 2021-06-03T03:55:48Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed research note Nota de investigación arbitrada https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/3187 10.7773/cm.v47i2.3187 https://hdl.handle.net/20.500.12930/7600 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/3187/420420559 Copyright (c) 2021 Ciencias Marinas application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 47 No. 2 (2021); 139–146 Ciencias Marinas; Vol. 47 Núm. 2 (2021); 139–146 2395-9053 0185-3880 |
