In the pigeon (Columba livia), a different response of cutaneous water evaporation (CWE) is seen at different acclimation states. While in heat-acclimated pigeons the CWE at high ambient temperatures will be activated as expected, no such response to

Several factors have an influence on the improvement of muscle activity and motor co-ordination of mammals during post-natal development. One of them is voltage sensitive L-type calcium channel function. In striated muscles of adult mammals these cha

The thermoregulatory function of the skin differs in adult cold-acclimated and heat-acclimated rock pigeons (Columba livia). In general, the cutaneous evaporative cooling mechanism is not activated by appropriate stimuli in cold-acclimated pigeons in

The photoreceptor cells in the compound eyes of higher diptera are clustered in groups (ommatidia) of eight receptor cells. The cells from six adjacent ommatidia are organized into optical units, neuro-ommatia sharing the same visual field. In those

1. 1.Cardiovascular and thermoregulatory responses to injections of neurotransmitters (1–10μ g of noradrenaline, NA; 10 μ g dopamine, DA; 10 μ g serotonin, 5-HT; 5 20 μ g acetylcholine, ACh) into the anterior hypothalamus were studied in the pi

1. 1. Fluorescence and electron microscopy were used to visualize differences between avian adipose tissue (AAT) collected from clavicular and abdominal regions of the great tit, the willow tit, the house sparrow and the Japanese quail, and interscap
