“…For this purpose, we constructed a composite tree from the available topologies of Liolaemini species where the species studied here were included. Our tree is based on several morphological and molecular studies, such as those of Lobo, Quinteros, Avila, Abdala and Frost (Lobo, 2001;Lobo, 2005;Lobo and Quinteros, 2005;Avila et al, 2006;Abdala, 2007;Lobo et al, 2010; Frost et al, 2001), for the Leiosaurine, our outgroup species. We built a resulting tree topology from the combination of the abovementioned studies because a complete phylogenetic tree for all the species studied here is not available (Fig.1).…”

SUMMARYThe variation in substrate structure is one of the most important determinants of the locomotor abilities of lizards. Lizards are found across a range of habitats, from large rocks to loose sand, each of them with conflicting mechanical demands on locomotion. We examined the relationships among sprint speed, morphology and different types of substrate surfaces in species of lizards that exploit different structural habitats (arboreal, saxicolous, terrestrial and arenicolous) in a phylogenetic context. Our main goals were to assess which processes drive variability in morphology (i.e. phylogeny or adaptation to habitat) in order to understand how substrate structure affects sprint speed in species occupying different habitats and to determine the relationship between morphology and performance. Liolaemini lizards show that most morphological traits are constrained by phylogeny, particularly toe3, the femur and foot. All ecological groups showed significant differences on rocky surfaces. Surprisingly, no ecological group performed better on the surface resembling its own habitat. Moreover, all groups exhibited significant differences in sprint speed among the three different types of experimental substrates and showed the best performance on sand, with the exception of the arboreal group. Despite the fact that species use different types of habitats, the highly conservative morphology of Liolaemini species and the similar levels of performance on different types of substrates suggest that they confer to the ʻjack of all trades and master of noneʼ principle.Supplementary material available online at http://jeb.biologists.org/cgi/content/full/215/5/774/DC1 Key words: substrate structure, performance, limb morphology, speed, lizard. THE JOURNAL OF EXPERIMENTAL BIOLOGY 775Sprint performance of lizards known about how substrate structure affects speed in species that use different microhabitats, such as climbing and terrestrial lizards (Irschick et al., 1997;Zani, 2000;Higham and Russell, 2010;Tulli et al., 2011a).The focal subjects of our study are Liolaemini lizards, which are members of one of the most diverse and species-rich lizard clades of the world Quinteros et al., 2008;Lobo et al., 2010; Breitman et al., 2011). Liolaemini lizards occur in South America, from central Perú to Tierra del Fuego and from the Pacific to Atlantic coasts, across mostly deserts and highelevation habitats (Cei, 1986). The line of this clade dates from 12.6 to 18 million years ago (Schulte et al., 2000;Albino, 2011). Some species show specialized morphology, for example the sanddweller species of the Liolaemus wiegmannii group (Etheridge, 2000), whereas some others exhibit signs of isolation after the last glacial period (Breitman et al., 2011). Thus, these species show a diversity in habitat usage, including generalized terrestrial as well as habitat specialists living on arboreal substrates, rock boulders (using the crevices or slipping underneath them) or sand (Halloy et al., 1998;Schulte et al., 2004;Tulli et al., 2009;Tul...

Based on the results of a phylogenetic analysis of morphological, skeletal and cytogenetic characters of Phymaturus, Lobo and Quinteros (2005) reported that the northern species of the P. palluma Group (that occur in northwestern San Juan, approximately north of 30 o 20' S), represent a monophyletic subgroup, which was named the Puna Clade (Lobo et al 2010).

A new species of Phymaturus of the P. mallimaccii Group from the Andes of central Chile (Iguania: Liolaemidae). A new species of Phymaturus from the Provincia Mountain in the San Ramón Mountains in the Metropolitan Region of Chile is described. It is a member of the P. palluma Group and the P. mallimaccii subgroup. The new species can be distinguished from other members of the P. mallimaccii subgroup by having a highly fragmented subocular scale (4 or 5), a preocular scale that is smaller than the canthal, males having a olive dorsum with a diffuse pattern of light bands on the paravertebral fields and a light triangle between the shoulders, which has the apex of the triangle oriented toward the snout. The distribution of new species lies south of that of other members of the P. mallimaccii subgroup, from which it is completely isolated. The low abundance of the new species is noteworthy. Information about the natural history of the lizard is provided and some aspects of unnamed populations of Chilean Phymaturus are discussed.

Ecomorphological studies of lizards have explored the role of various morphological traits and how these may be associated with, among other things, habitat use. We present an analysis of selected traits of internal morphology of the hind limbs of Neotropical iguanian lizards and their relationship to habitat use. Considering that one of the most widely-held hypotheses relating to the origin of grasping is associated with the exploitation of the narrow-branch arboreal habitat, we include subdivisions of this designation as two of our ecologically defined categories of habitat exploitation for analysis, and compare lizards assigned to these categories to the features displayed by terrestrial lizards. The influence of phylogeny in shaping the morphology of lizards was assessed by using the comparative method. K values were significant for several osteological traits. Most of the K values for the variables based upon muscle and tendon morphometric characters (13 out 21), by contrast, had values <1, suggesting that their variation cannot be explained by phylogeny alone. Results of our phylogenetic and conventional ANCOVA analyses reveal that the characters highlighted through the application of the comparative method are not absolutely related to habitat in terms of the categories considered here. It appears that the bauplan of the lizard pes incorporates a morphological configuration that is sufficiently versatile to enable exploitation of almost all of the available habitats. As unexpected as conservation of internal gross morphology appears, it represents a means of accommodating to environmental challenges by apparently permitting adequacy for all situations examined.
