Hormone steuern durch komplexe Regelkreise die Anpassungen von Organismen an ihre Umwelt. Verändern sich diese hormonellen Regelkreise schnell genug, um mit den weltweit immer schneller werdenden Umweltveränderungen mitzuhalten? Am Hormon Kortikosteron wird bei Vögeln gezeigt, dass verschiedene Arten unterschiedliche Konzentrationen aufweisen…
