Resumen:
Ecophysiology and conservation studies often require prior the establishment of baseline physiological metrics. For instance, expected reference intervals for health metrics are valuable tools for veterinarians and conservationists who monitor the health status of endangered populations and species. This study first establishes reference intervals for hematological metrics in free-ranging Olrog´s gull (Larus atlanticus) during the non-breeding season. Fifty-six gulls (immature and adults) were captured and studied in Mar del Plata and neighboring coastal areas (Buenos Aires, Argentina) during winters 2018 (n = 22) and 2019 (n = 34). We analyzed hematocrit, red blood cells (RBC, erythrocytes), hemoglobin, mean cell volume (MCV), mean cell hemoglobin (MCH), mean cell hemoglobin concentration (MCHC), white blood cells (WBC, leukocytes), heterophils, lymphocytes, eosinophils, monocytes and basophils. Additionally, we analyzed the variability of hematological metrics according to body weight, sex, age, and calendar year. Hematologic metrics were in line with those reported in other seabird species. Males had greater body weight and MCH than females. The heterophil-to-lymphocyte ratio (HL ratio), and lymphocyte levels were higher in adults than in immatures. Hematocrit, WBC, heterophils, and basophils also varied significantly between calendar years. The results highlight the importance of appropriate metrics and reference intervals for monitoring health status of this threatened species, and we recommend implementing such comparative assessments among populations.
