Anaerobic metabolism and activity of European lacertid lizards. 1987

M H McClelland

1. Lactate production and physical performance during intense activity were measured in Lacerta vivipara, Podarcis muralis and Podarcis hispanica, temperate lizards from progressively lower latitudes. 2. Rates of lactate production during the initial 30 sec of bursts of activity (means = 1.75 mg g-1) and their Q10S (means = 1.36) are similar to previously obtained values for lizards. 3. Maximal anaerobic scope at activity body temperatures is lowest in Lacerta vivipara, which correlates with a tendency to less strenuous behaviour than that of the Podarcis species and may reflect the need for energy economy. 4. Q10S of maximal performance are lower in Lacerta vivipara and Podarcis muralis than Podarcis hispanica, a difference having no demonstrated metabolic basis but which is thermally adaptive for these cooler climate species.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
