Proceedings of the United States National Museum SMITHSONIAN INSTITUTION • WASHINGTON, D.C. Volume 122 1967 Number 3595 Ecology and Social Organization In the Iguanid Lizard Anolis lineatopus By A. Stanley Rand * Introduction This paper reports the findings of a fO-montli (August 1961 to June 1962) field study of the ecology and behavior, particularly the social behavior, of Anolis lineatopus, in edificarian situations, in the vicinity of Kingston, Jamaica. The geographical variation of this common Jamaican lizard has been discussed by Underwood and Williams (1959) and by Grant (1940) but, beyond brief notes in these papers and in Barbour (1910), its natural history has never been described. There have been a number of detailed studies on free-living lizards, but most of them have dealt with temperate zone species in tem-perate environments. Few investigators have had the opportunity to conduct intensive and extensive studies on lizards in the tropics. The few exceptions include Evans (1951), Harris (1964), and Hirth , (1963 a and b). No extended field study with an emphasis similar 1 to this one has been published on any tropical Anolis though the shorter papers of Evans (1938a) and Oliver (1948) report relevant • Zoologist, Smithsonian Tropical Research Institute, Box 2072, Balboa, Pan-ama Canal Zone.
