The study aims to assess blood gas and lactate levels in loggerhead and green turtles during nesting to establish reference intervals and identify physiological differences.
Collected blood samples from 49 loggerhead and 30 green turtles during nesting seasons.
Analyzed blood gas and lactate levels using point-of-care analyzers.
Evaluated correlations between blood analytes and various biological factors, including morphometrics and nest deposition date.
Established species-specific reference intervals for blood gas and lactate levels.
Loggerheads showed higher oxygen levels, while green turtles had higher carbon dioxide and bicarbonate levels.
Lactate correlated positively with curved carapace length in loggerheads, indicating physiological changes during nesting.
