Resumen

La foca leopardo (Hydrurga leptonyx) es una especie poco estudiada a nivel genético. Con el fin de realizar la primera evaluación de la diversidad genética de esta especie en la costa de Danco (Península Antártica), se secuenció 423 pb de la Región Control del ADN mitocondrial (ADNmt-CR) de 13 muestras de sangre colectadas en la Base Primavera (62º15’S, 58º39’W) durante el verano austral 2011-2012. Los resultados mostraron una alta diversidad de haplotipos (h = 0.99), con varios haplotipos divergentes. Nuestros hallazgos genéticos sugieren que las focas leopardo de la costa de Danco podrían representar diferentes filogrupos; sin embargo, es necesario incluir más marcadores genéticos para confirmar esta hipótesis.
