The red (Ailurus fulgens) and giant (Ailuropoda melanoleuca) pandas are mammalian carnivores convergently adapted to a bamboo feeding diet. However, whereas Ailurus forages almost entirely on younger leaves, fruits and tender trunks, Ailuropoda relies more on trunks and stems. Such difference in foraging mode is considered a strategy for resource partitioning where they are sympatric. Here, we ...

The pa tte rn of innervation in the frog’s heart shown by silver staining has been compared w ith the results of histochemical methods. The muscle innervation is a series of dense n e t­ works of nerve bundles. These have been divided into four groups according to their size and distribution. The silver m ethods show fewer fibres than the histochemical methods bu t all the methods show the same...

The cervical sympathetic trunks innervate the carotid bodies, carotid baroreceptors, thyroid gland and the upper airway mucosa, structures which can influence breathing and upper airway resistance. However, their role in the control of ventilation and upper airway patency is poorly understood. A constant airflow was applied to the upper airway through a high-cervical tracheostomy in anaesthetiz...
