Wildtiere reagieren ähnlich wie Menschen mit der Ausschüttung von Hormonen wie Cortisol auf Belastungen oder Störungen. Die Konzentration solcher Hormone kann berührungsfrei aus Haarproben der Tiere ermittelt werden. Um den Einfluss verschiedener Belastungen oder Störungen – etwa Konkurrenz um Nahrung, Flucht vor Raubtieren oder sich ändernde Umweltbedingungen – zu ermitteln, werden Basiswerte der relevanten Hormone für jede Tierart benötigt. Daher untersuchte ein Forschungsteam des Leibniz-Instituts für Zoo- und Wildtierforschung (Leibniz-IZW), ob in Tierhaaren eingelagerte Glukokortikoid-Hormone ein zuverlässiger Biomarker für Belastungssituationen sein können. Bei dieser Untersuchung stieß das Team auf eine bisher unbekannte Fehlerquelle bei der häufig verwendeten antikörperbasierten Enzym-Immunassay-Analysemethode zur Qoclawqcqc soq „Rdofkq“-Difzqe-Aynnnpmbgnzdaqq.
