Ontogenetic change in blood oxygen capacity and maximum activity in garter snakes (Thamnophis sirtalis)
(Springer: Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1977-01)
There is an ontogenetic increase in the time that garter snakes (Thamnophis s. sirtalis) can maintain maximum activity at 25°C. Newborn snakes are exhausted by 3–5 min of activity while adults can be active for 20–25 min. ...
Physiological basis of habitat partitioning in Jamaican Eleutherodactylus
(Springer: Oecologia, 1977-12)
Rate of evaporation, resistance to drying, temperature selection, and critical thermal maximum were measured for Jamaican Eleutherodactylus acclimated to 20° C and a 12:12 L:D photoperiod. Two introduced species, E. ...
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 ...
The dependence of postreplication repair on uvrB in a recF mutant of Escherichia coli K-12
(Springer: Molecular and General Genetics, 1977-01)
Summary Mutants carrying recF143 or recF144 show wild type levels of host cell reactivation of UV-irradiated lambda vir and wild type rates of excision gap closure in repairing UV damage to their own DNA. The same mutants ...

Melanin deposits associated with the venom glands of snakes
(Wiley: Journal of Morphology, 1978-01)
Melanin deposits in the heads of both true vipers (Viperinae) and pit vipers (Crotalinae) are concentrated over the dorsal and dorsolateral aspects of the venom glands. This pigment may occur in any or all of six sites ...
