“…Además, P. bordai mantuvo similitudes térmicas con lagartijas nocturnas de lugares semiáridos como H. turcicus (Hitchcock & McBrayer 2006), Nephrurus stellatus (Angilletta & Werner 1998), P. microphyllus (Werner et al 1996), Christinus marmoratus (Kearney & Predavec 2000) y con su especie simpátrida P. tuberculosus (Lara-Resendiz et al En prensa). Por el contrario, lagartijas nocturnas tropicales como Coleonyx brevis, C. variegatus, Hemidactylus frenatus y Lepidodactylus lugubris mantuvieron temperaturas ligeramente más altas (Huey et al 1989). Esto sugiere que la población estudiada de P. bordai es similar a otras especies nocturnas de clima semiárido, a pesar de ser la especie que se encuentra casi en el límite de la distribución altitudinal del género (Dixon, 1964).…”

“…A fruit supplement was also provided for P. dubia and R. auriculatus. Prior to experimentation, geckos were allowed at least 1 h to equilibrate to test temperature (26.2±0.04°C) and humidity (61.4±0.13%), and then chased by hand along a 1 m race track (Huey et al, 1989). Temperature and humidity were held constant across species to control for a complicated interaction between these parameters and adhesion (Niewiarowski et al, 2008).…”

The gecko adhesive system has been under particular scrutiny for over a decade, as the field has recently attracted attention for its application to bio-inspired design. However, little is known about how the adhesive system behaves in ecologically relevant conditions. Geckos inhabit a variety of environments, many of which are characterized by high temperature, humidity and rain. The van der Waals-based gecko adhesive system should be particularly challenged by wet substrates because water can disrupt the intimate contact necessary for adhesion. While a few previous studies have focused on the clinging ability of geckos on wet substrates, we tested a dynamic performance characteristic, sprint velocity. To better understand how substrate wettability and running orientation affect locomotor performance of multiple species on wet substrates, we measured average sprint velocity of five species of gecko on substrates that were either hydrophilic or intermediately wetting and oriented either vertically or horizontally. Surprisingly, we found no indication that wet substrates impact average sprint velocity over 1 m, and rather, in some species, sprint velocity was increased on wet substrates rather than reduced. When investigating physical characteristics and behavior that may be associated with running on wet substrates, such as total number of stops, slips and wet toes at the completion of a race, we found that there may be habitat-related differences between some species. Our results show that in general, unlike clinging and walking, geckos running along wet substrates suffer no significant loss in locomotor performance over short distances.

“…Among lizards, locomotion is directly related to escape behavior, habitat domain, 34 and hunting mode (Huey et al, 1984;1989;Irschick & Losos, 1998). The study of these 35 metrics have enabled valuable insights within an evolutionary framework, across species 36 and contexts (Huey, 1982;Bauwens et al, 1995).…”
