“…However, other studies of ancestrally padless geckos are inconclusive (Persaud, Werner & Werner ; Werner et al . ). Hence, characterizing the interplay between the evolution of the adhesive system and habitat use may reveal consequences of selection on escape behaviour, performance and morphology.…”

“…Interestingly, a study by Cooper & Whiting (2007) found that escape behaviour depends on habitat structure in Rhoptropus boultoni, a boulder-dwelling gecko equipped with an adhesive system. However, other studies of ancestrally padless geckos are inconclusive (Persaud, Werner & Werner 2003;Werner et al 2004). Hence, characterizing the interplay between the evolution of the adhesive system and habitat use may reveal consequences of selection on escape behaviour, performance and morphology.…”

Summary1. Morphological features that lead to increased locomotor performance, such as faster sprint speed, are thought to evolve in concert with habitat use. The latter depends on available habitat structure and how the animal moves within that habitat. Thus, this behavioural variation will impact how natural selection acts on locomotion and morphology. 2. Quantifying the interplay between escape behaviour and locomotor morphology across habitats that vary in structural composition could reveal how selection acts on locomotion at local levels. Substrate features, such as incline and topographical variation, are likely key drivers of morphological and functional disparity among terrestrial animals. We investigated the impact of habitat variation and escape behaviour on morphology, including the adhesive system, of Rhoptropus afer, a diurnal and cursorial gecko from Namibia. Substrate incline and topographical variation are likely important for this pad-bearing gecko due to the trade-off between adhering and sprinting (i.e. using adhesion results in decreased sprint speed). 3. We corroborate the hypothesis that the adhesive system exhibits the greatest degree of reduction in populations that utilize the flattest terrain during an escape. Our findings suggest that the adhesive apparatus is detrimental to rapid locomotion on relatively horizontal surfaces and may thus be counterproductive to the evasion of predators in such situations. A broad scale analysis of geckos would determine whether diversity of adhesive morphology is driven primarily by habitat use. 4. Phenotypic plasticity of the adhesive system and interspecific competition are plausible candidates for driving our results. However, it is unclear whether the differences we observed have a genetic basis. Future work should focus on how variation of the adhesive system impacts downstream locomotor components such as kinematics and mechanics and how the integration of these traits is related to habitat use.

“…In contrast, Cooper (1995) defined the Gekkonoidea exclusive of the Eublepharidae (Underwood 1954) as SW, and the Eublepharidae as WF. This last conclusion remained unproven until Werner et al (2001Werner et al ( , 2004 showed that Goniurosaurus kuroiwae orientalis was, compared to other geckos, quite WF. However, definition of this species as WF resulted from statistical summation of extremely heterogeneous behaviour.…”

“…In this model group, most of the species consistently employ one of the two FMs, although temporal variation may occur (Huey and Pianka 1981). This stability has enabled the identification of morphological, physiological, behavioural and ecological correlates (sometimes considered 'consequences') of the two FMs (Werner and Frankenberg 1989;Perry 1999; references in Werner et al 2004). Moreover, usually all or most species of a family share a similar FM.…”
