Lebensgeschichte und Hormone - Warum unterscheiden sich Arten und Individuen so stark in ihren Hormonkonzentrationen?

Vogelindividuen zeigen immense Unterschiede in der Konzentration von Hormonen wie Testosteron oder Corticosteron. Welche Umweltbedingungen, welche sozialen Ereignisse und welche inneren Faktoren führen zu diesen Unterschieden? Und wie wirken sich die unterschiedlichen Hormonkonzentrationen auf Überlebenswahrscheinlichkeit, Gesundheit, Fertilität und Fortpflanzungserfolgs von Individuen aus?
