On the Biology of Tropidurus delanonis, Baur (Iguanidae)

Zeitschrift für Tierpsychologie, 1978
AbstractA field study of Tropidurus delanonis was carried out on an uninhabited island (Hood) of the Galapagos Archipelago over 18 months. The purpose of the study is to show the interrelation between social structure, behaviour and ecological aspects of the iguanid lizard Tropidurus delanonis.

The Ethoecology of Anolis nebulosus (Sauria, Iguanidae)

Journal of Herpetology, 1970
A population of Anolis nebulosus located near Tepic, Nayarit, Mexico was studied in the field and laboratory from June, 1965 to September, 1968. The population showed a female : male sex ratio of 50:49. The males in the spring were larger than the females, averaging 41.4 and 35.8 mm, respectively; however, no difference in the length-weight ...

Neuroepithelial bodies in the lung of Basiliscus vittatus (Reptilia, Iguanidae)

The Anatomical Record, 1994
AbstractBackground: Neuro‐epithelial bodies (NEB) are corpuscles of currently equivocal function which are present in the lungs of vertebrates. Comparative studies may help to elucidate their role.Methods: The NEB of Basiliscus vittatus (Reptilia, Iguanidae), a terrestrial lower vertebrate able to dive, are for the first time examined by electron ...

Ultrastructural Analysis of Spermiogenesis in Iguana iguana (Reptilia: Sauria: Iguanidae)

European Journal of Morphology, 2002
Spermiogenesis in the lizard, Iguana iguana, was studied by transmission and scanning electron microscopy. During this process, structures such as the acrosomal complex in the spermatid head and the axonemal complex in the mid and principal pieces of the flagellum are formed. The nuclear content is initially compacted into thick, longitudinal chromatin

Tongue structure and function in Oplurus cuvieri (reptilia: Iguanidae)

The Anatomical Record, 1994
AbstractThe anatomy of the hyo‐lingual apparatus in the iguanid lizard Oplurus cuvieri has been studied by light microscopy and scanning electron microscopy. Four areas were observed on the dorsal lingual epithelium of the lizard. Tongue tips are covered with a smooth epithelium.

Minute Y chromosome in the lizard genus Uta (family Iguanidae)

Cytogenetics, 2008
Evidence is presented for an XX/XY sex-determining mechanism in five species of the genus Uta. All species examined have a somatic diploid complement of 12 macrochromosomes and 22 microchromosomes. The Y chromosome is morphologically distinguishable as the smallest microchromosome in the males.

A Comparative Study of Display Behavior in Phrynosoma (Iguanidae)

The Southwestern Naturalist, 1965
The behavior of six of the seven species of Phrynosoma found in the United States was studied. Most of the behavior patterns typical of iguanids are lacking in this genus. Analysis of display-action-pattern graphs is presented. These show a gradual decrease in display complexity from primitive to more recent forms.

Systematics of the Ctenosaura group of lizards (Reptilia: Sauria: Iguanidae)

Amphibia-Reptilia, 2000
Abstract The phylogenetic relationships of the species of the genus Ctenosaura were analysed using two independent data sets derived from morpho-etho-ecological and genetic (RAPD) markers. The analysis of the data matrix based on morpho-etho-ecological characters yielded a consensus tree with the species of ...

The Hispaniolan Anolis (Reptilia, Lacertilia, Iguanidae) of the hendersoni Complex

Journal of Herpetology, 1978
Geographic variation in three species of the hendersoni complex anoles (A. hendersoni, A. bahorucoensis, A. dolichocephalus) indicates that in each case there are northern and southern slope subspecies, separated from each other by the interior high uplands of the montane massifs of the Hispaniolan Tiburon Peninsula and the Peninsula de Barahona.
