Simple Summary
To address the physiological response to low-temperature stress in the invasive turtle species, we investigated the hepatic metabolite alteration of Trachemys scripta elegans hatchlings under low-temperature treatments. Our results indicated that the levels of hepatic metabolites, e.g., stearolic acid, taurohyocholate, and spermidine, changed significantly in low-temperature-exposed turtles. Despite having only limited impacts on fatty acid and energy metabolism, short-term low-temperature exposure might alter the immune ability of turtles.
Abstract
Investigating the physiological and biochemical changes of ectothermic species before entering hibernation would contribute to the understanding of how they adapt to low-temperature environments. Here, red-eared slider turtle (Trachemys scripta elegans) hatchlings were maintained under different thermal treatments (24 °C, slowly decreasing temperatures from 24 °C to 14 °C, and to 4 °C). Hepatic metabolite alterations were measured to assess the metabolic impacts of low-temperature stress in this species. Of these differentially changed metabolites, some (e.g., raffinose, spermidine, allocholic acid, taurohyocholate, 2-ketobutyric acid, acetylcysteine) were shown to decrease, while others (e.g., stearolic acid, D-mannose) increased in low-temperature treatments. Our results indicated that short-term low-temperature stress might have limited impacts on lipid and energy metabolism in this species. The changes in other metabolites (e.g., allocholic acid, taurohyocholate, spermine, acetylcysteine) might be associated with a low food intake (and thus reduced digestive performance) and weakened immune ability of low-temperature-exposed animals.
