Item Repetibilidad de la Tasa Metabólica de Mytilus Galloprovincialis (Bivalvia: Mytilidae) a Temperatura de Aclimatación y Post Incremento Agudo de 5°C.(Universidad de Concepción., 2022) Sobarzo Ibacache, Paulina; Urbina Fonerón, Mauricio AndrónicoRepeatability studies, also known as the intraclass correlation coefficient, have been the subject of interest in various areas such as physiology and ecology since they allow evaluating the need for an individual trait and its consistency over time. Mytilus galloprovincialis is a marine bivalve belonging to the Mytilidae family, introduced to Chile from the Mediterranean. Due to its wide latitudinal distribution, it is exposed to various environmental conditions, which makes it a suitable model for a wide variety of studies, such as population genetics, biological monitoring, ecology, physiology, and metagenomics, among others. In this work, we estimate repeatability of the metabolic rate of Mytilus galloprovincialis at its acclimatization temperature (17ºC) and when it was exposed to short periods of higher temperature 22 ± 1ºC. In addition, the correlation between both metabolic rates and both temperatures are evaluated, and whether the metabolic rate differs according to the measurement time is also evaluated. According to the results obtained, the metabolic rate is a repeatable trait at both temperatures. Also, it was found that metabolic rates and temperatures are significantly correlated, so temperature did not greatly influence metabolic rates, therefore, it did not influence the repeatability of this trait. On the other hand, the evaluation of the effect of the measurement time on the metabolic rates indicated that these differ depending on the measurement time.
