Acid precipitation and embryonic mortality of spotted salamanders, Ambystoma maculatum
(American Association for the Advancement of Science: Science, 1976-04-02)
Spotted salamanders breed in temporary pools formed in early spring by melted snow and rain. Many of these pools reflect the low pH of precipitation in the northeastern United States. Egg mortality is low (less than 1 ...
The role of fatigue in temperature resistance of salamanders
(Elsevier: Journal of Thermal Biology, 1976-04)
1. We measured temperature resistance and lactic acid production of Notophthalmus viridescens and Plethodon cinerus acclimated to 10, 20 or 30°C.
2. Fatigue is responsible for the Loss of Righting Response (LRR) observed ...
Salt excretion in a beach lizard (Ameiva quadrilineata, Teiidae)
(Springer: Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1976-01)
The teiid lizardAmeiva quadrilineata has a nasal salt gland that responds to NaCl loading by increasing excretion of Na+ (from 1.12 to 2.63 uM/100 gh), K+ (from 0.14 to 2.43 uM/100 gh), and Cl– (from 1.10 to 5.47 uM/100 ...
