Diversity of functional microornamentation in slithering geckos Lialis (Pygopodidae).
The skin of geckos is covered with countless microscopic protuberances (spines). This surface structure causes low wettability to water. During evolution, representatives of the recent gekkotan clade Pygopodidae started slithering on the ground. This manner of locomotion affected limb reduction resulting in a snake-like body. Regarding abrasion and frictional properties, a surface covered with ...
متن کاملEcology and Behaviour of Burton’s Legless Lizard (Lialis burtonis, Pygopodidae) in Tropical Australia
Many lizard lineages exhibit bodily elongation and concomitant limb reduction. This morphotype has evolved independently in numerous taxa, including amphisbaenians, anguids, cordyl ids , dibamids, diploglossids, gerrhosaurids, skinks, and teiids (Greer, 1991). Of the phylogenetic lineages that have undergone major adaptive radiations subsequent to limb loss, by far the most speciose and diverse...

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Determination of effective environmental factors on plants functional diversity and species diversity in Ravar rangelands
The aim of the study was to investigate affecting environmental factors on functional diversity indices and species diversity for the fluctuation of the management according to the ecological conditions in Raver rangeland. To determine the functional attributes of rangeland plants, 12 height points were selected along elevation gradient those were distance between them100 meters. 5 sampling plo...
متن کاملSlithering Locomotion
Limbless terrestrial animals propel themselves by sliding their bellies along the ground. Although the study of dry solid-solid friction is a classical subject, the mechanisms underlying friction-based limbless propulsion have received little attention. We review and expand upon our previous work on the locomotion of snakes, who are expert sliders. We show that snakes use two principal mechanis...
