Phylogenetic relationships and limb loss in sub-Saharan African scincine lizards (Squamata: Scincidae).
Skinks are the largest family of lizards and are found worldwide in a diversity of habitats. One of the larger and more poorly studied groups of skinks includes members of the subfamily Scincinae distributed in sub-Saharan Africa. Sub-Saharan African scincines are one of the many groups of lizards that show limb reduction and loss, and the genus Scelotes offers an excellent opportunity to look ...
متن کاملDistinct Patterns of Desynchronized Limb Regression in Malagasy Scincine Lizards (Squamata, Scincidae)
Scincine lizards in Madagascar form an endemic clade of about 60 species exhibiting a variety of ecomorphological adaptations. Several subclades have adapted to burrowing and convergently regressed their limbs and eyes, resulting in a variety of partial and completely limbless morphologies among extant taxa. However, patterns of limb regression in these taxa have not been studied in detail. Her...
متن کاملPotential role of interleukin-1 at the peri-ovulation stage in a species of placental viviparous reptile, the three-toed skink, Chalcides chalcides (squamata: scincidae)
We recently showed that interleukin-1 (IL-1) is secreted by the placenta of a species of squamate reptile, the three-toed skink, Chalcides chalcides. In this study, we used immunohistochemical techniques to investigate the expression of IL-1 (in the two isoforms, IL-1alpha and IL-1beta) and its specific membrane receptor IL-1 RtI in uterine oviduct during the peri-implantation period. We found ...
متن کاملUltrastructure of the lingual epithelium of adult scincine lizard Chalcides ocellatus
In the present investigation, the histological and histochemical characteristics, as well as the ultrastructure of the lingual epithelium of the adult lizard Chalcides ocellatus, were investigated by light microscopy (LM) and scanning electron microscopy (SEM). Histological examination revealed taste buds and sensory papillae on the tongue tip and on the foretongue. The papillae were covered by...
متن کاملHabitat use in south-west European skinks (genus Chalcides)
Background Congeneric species of reptiles frequently exhibit partitioning in terms of their use of habitats or trophic resources in order to reduce competition. In this study, we investigated habitat use by two species of European skinks: Chalcides bedriagai and Chalcides striatus, based on 49 records from southern France, Spain, and Portugal. Methods We measured three levels of niche descrip...
