The ontogeny of display behavior in Sceloporous undulatus hyacinthinus (Sauria: iguanidae)
Displays of 36 Sceloporus undulatus hyacinthinus from 8 clutches were recorded on video tape from the day of hatching to adult size during 1978, 1979, and 1980. Nine hundred forty-one displays were analyzed frame by frame, and durations of display units were calculated to the nearest 0.01 s. From …

Contribuição ao estudo do crânio de Placosoma Tschudi, 1847 (Sauria: Teiidae: Gymnophthalminae)
… cranial osteology of Placosoma Tschudi, 1847 (Sauria, Teiidae, Gymnophthalminae), comparing the cranium of different species. For this study, was used the methods of Taylor and Van Dyke (1985), for clearing and staining the skulls, as well as other techniques. Detailed descriptions of cranial …

Structure and social significance of vocalization by Anolis grahami grahami (Sauria: Iguanidae)
Even though the ability to produce vocalizations by the vibration of a membrane is widespread throughout the lizard suborder, only the sounds of geckos (Gekkonidae) have been closely studied. The purposes of this study were to describe the physical structure, social significance, and means of sound …

Behavioral comparison of anoline competitors: Anolis cooki and Anolis cristatellus (Reptilia: Sauria: Iguanidae)
The behavioral repertoire of the Puerto Rican anoles, Anolis cooki, A. cristatellus and A. monensis was studied in the laboratory. The display of A. cooki and A. monensis revealed great similarities; consisting of one head bob pattern highly stereotyped in its temporal sequencing and total …

Behavioral, temporal, and spatial relationships in free-ranging female Anolis carolinensis (Sauria: Polychridae)
The behavior and spatial relationships of 7 male and 22 females were described from 56 days of observation from focal and scan samples made between 0830 and 1830 h during May-July, 1993 at the Augusta Canal near Augusta, Georgia. Behavioral observations indicated that females primarily remain …

A functional morphological study of limb regression in some Southern African species of Scincidae (Reptilia : Sauria)
How and why did limblessness evolve in certain skinks? These questions are explored in certain species of the Scincidae (from southern Africa) that vary in the degree of limb reduction. This regression series consists of Mabuya capensis (with normal, pentadactyle limbs), Riopa sundevallii (with …

Morfologia e ultra-estrutura do oviduto de Hemidactylus mabouia (Moreau de Jonnès, 1818) (Reptilia, Squamata, Sauria, Gekkonidae) durante o ciclo reprodutivo
Em geral, o aparelho reprodutor feminino dos répteis é constituído por um par de ovários e pelos ovidutos que funcionam como um conduto para o ovo desde a ovulação até a oviposição. As lagartixas pertencem ao gênero Hemidactylus, o qual está inserido na família Gekkonidae e na ordem Squamata. A …

Predation on lizard eggs by ants: interaction modifications in an unstable physical environment
The importance of abiotic influences on the strength of biotic interactions is largely unknown. To explain large annual fluctuations in the population size of the tropical lizard, Anolis limifrons, on Barro Colorado Island, Panama, I hypothesized that annual variation in lizard population size is …
