A Motion Picture Study of Maternal Behavior of the Lizard, Eumeces obsoletus Baird and Girard

Comparison of Tongue Extrusions in Representatives of Six Families of Lizards

“…Evans (1961) and Underwood (1970) pointed out that among the autarchoglossids (a classificaton by Camp, 1923 which includes scincids, teiids and helodermatids), although vision may still be important, the system of chemoreception involving the tongue and the organ of Jacobson is elaborated to a much greater extent than in iguanids and agamids (division Ascalabota). It is obvious that the tongue-Jacobson's organ system must play important roles in the lives of many lizards.…”

“…Behavioral studies to determine the functions of the Jacobson's organ in lizards have produced contradictory results. The organ has been implicated in food seeking (Bogert and Martin del Campo, 1956;Kahmann, 1939;Noble and Kumpf, 1936), orientation (Kahmann, 1939), maternal behavior (Evans, 1959;Noble and Kumpf, 1936;Noble and Mason, 1933), sex recognition/ courtship (Greenberg, 1943), species identification (Hunsaker, 1962), exploration (Berry, 1974), predator detection (Berry, 1974) and detection of conspecifics (Berry, 1974).…”

Releaser-induced recognition learning by amphibians and reptiles

“…Parental care in amphibians and reptiles is mostly absent, but occasionally very extensive and detailed parental behavior has been observed. Evans (1959) …”

Precocity, Play, and the Ectotherm-Endotherm Transition

“…Although most squamates seem to ignore their eggs once laid, there are lizards that brood their eggs until hatching and stay with them for at least a few days postnatally (Evans, 1959). In Ophisaurus, the mother may even alter the depth of her eggs in the substrate in response to temperature fluctuations (Vinegar,1968).…”
