The home ranges of two congeneric desert lizard species (Acanthodactylus schmidti and Acanthodactylus boskianus) were studied near Riyadh over two seasons. Male lizards had larger home ranges than females and, in general, spring home ranges were greater than winter home ranges.

Environmental Monitoring and Assessment, 2022
As an indicator of physiological state of lizards, thermoregulatory behavior has been proposed as an assessment tool of environmental contamination, particularly in desert ecosystems where lizards represent a major biological component. Although pesticide contamination has been shown to induce behavioral fever in lizards, the possible pyrogenic effect ...

Skin-derived semiochemicals of the lacertid lizard Acanthodactylus boskianus
Amphibia-Reptilia, 2016Skin lipids impede transcutaneous water loss in several species of squamate reptiles and act as a barrier to harmful microorganisms; they play an additional role as chemical cues involved in chemical communication eliciting behavioral responses in intra- and interspecific interactions.

The Acanthodactylus boskianus species group includes three species (A. boskianus, A. nilsoni, and A. schreiberi) of unclear phylogeny and phylogeographic history. By sequencing fragments of two mtDNA genes and performing phylogenetic, demographic, and chronophylogenetic analyses, we aimed at identifying their phylogenetic relationships while ...

Bulletin of Environmental Contamination and Toxicology, 2020
Lizards increasingly are recognized as suitable contaminant biomonitors in terrestrial ecosystems. Previously, we have shown that Bosk's fringe-toed lizards (Acanthodactylus boskianus) living close to the Gabès-Ghannouche industrial complex for fertilizer and acid production in southern Tunisia were contaminated by heavy metals.

AbstractThe current observations focused on the ultrastructure comparison between the tongue of two reptile species endemic the Egyptian fauna; Bosc's fringe‐toed lizard Acanthodactylus boskianus and Sinai fan‐fingered gecko Ptyodactylus guttatus to exhibit the relationship between the lingual epithelium and its function according to their specific ...

AbstractInvestigating how patterns of sexual size dimorphism vary among local populations may be useful for understanding size evolution in lizards. We investigated patterns of sexual size dimorphism in a Tunisian population of Bosk's fringe-toed lizards Acanthodactylus boskianus asper, in relation to a Middle-eastern population of the same subspecies.

Abstract 1. 1. The standard metabolic rate (SMR) of Acanthodactylus boskianus was determined at 20, 25, 30 and 35°C during winter and summer acclimatization, using constant pressure manometric respirometers. 2. 2. Values for the exponent b of body mass in relation to metabolic rate ranged from 0.50 to 0.63. 3. 3.

Zoology in the Middle East, 2013
Acanthodactylus boskianus are reproductively active in Israel from March to June. Mean clutch size was 3.2 ± 0.20, range 3–4. Males reach maturity at 50 mm snoutvent length, and females at 48 mm SVL respectively. The mean SVL of males was significantly larger than that of females. There was no evidence that females produce multiple clutches.
