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.

Femoral gland secretions are believed to play an important role in chemical communication and social organization of lizards. In spite of this, few studies have investigated the chemical composition and the behavioural roles of these secretions. The lacertid lizard Acanthodactylus boskianus is a good example, having these well-developed glands in both ...

Haemogregarina damiettae was previously described form Acanthodactylus boskianus in Egypt, and the description was base only on the blood stages with no data on the tissue stages. In the present study, both blood and tissue stages were encountered. The prevalence of infection was found to be 60 % (30/50).

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 ...

Abstract Integumental gland secretions in lizards have been postulated to play a role as semiochemicals, but few studies have analysed the chemical nature of the gland secretions used in communication. We analysed the femoral gland secretions of Acanthodactylus boskianus using GC–MS, compared secretions of both sexes and different ages of males.

Environmental pollution can have significant detrimental effects on animal populations (Hughes et al. in Science, 278:689–6923, 1997). Anthropogenic pressures have been increasing in the past decades in Gabes region, due to the installation of the Gabes-Ghannouche factory complex of phosphate treatment for fertilizer and acid production in the early ...

Competition can be keen within and between closely related species but can be reduced when sympatric individuals differ in resource use. To determine how sympatric, closely related species coexist, we examined movement and activity of foraging ...
