...Thomas Roeder ABSTRACT Octopamine (OA) and tyramine (TA) are closely related biogenic monoamines that act as signalling compounds in invertebrates, where they fulfil the roles played by adrenaline and noradrenaline in vertebrates. Just like adrenaline and noradrenaline, OA and TA are extremely...

... rate is associated with decreased stroke volume, leaving cardiac output unchanged. We explored the capacity of noradrenaline to overcome autoregulation in the anaconda heart. Electrically pacing in situ perfused hearts from the intrinsic heart rate to the maximum attainable resulted in a proportional...

Circulating catecholamine levels were extremely high in all species after fishing stress, with adrenaline levels 3–4 times higher than noradrenaline levels. Cortisol levels remained low, ranging from 1.33...
