Abstract

Breathing (fR) and heart (fH) frequencies decreases as aridity increases in 4 chromosomal species of the Spalax ehrenbergi that inhabits humid to arid habitats in Israel in the order 2n=52, 58, 54, 60. Breathing frequencies were 50.0, 46.9, 45.9, and 43.4% of the expected values, and fH were 37.6, 32.7, 27.8, and 25.8% for 2n=52, 58, 54, and 60, respectively. The decrease of fR and fH has a genetic basis and correlates with the metabolism of the mole rat.
