Data from: T1R2-mediated sweet sensing in a lizard
<p>Sugars are an important class of nutrients found in the flowers and fruits of angiosperms (flowering plants). Although T1R2-T1R3 has been identified as the mammalian sweet receptor, some birds rely on a repurposed T1R1-T1R3 savory receptor to sense sugars. Moreover, as the radiation of flowering plants occurred later than the last common ancestor of amniotes, sugar may not have been an important diet item for amniotes early in evolution, raising the question of whether T1R2-T1R3 is a universal sugar sensor or only a mammalian innovation. Here, using brief-access behavioral tests and functional characterization of taste receptors, we demonstrate that the nectar-taking Madagascar giant day gecko (<em>Phelsuma</em> <em>grandis</em>) can sense sugars through the T1R2-T1R3 receptor. These results reveal the existence of T1R2-based sweet taste in a non-avian reptile, which has important implications for our understanding of the evolutionary history of sugar detection in amniotes.</p>
Blowing in the wind: Experimental assessment of clinging performance and behavior in Anolis lizards during hurricane-force winds
<p>1. Extreme weather events, such as hurricanes, can be ecologically devastating and cause widespread mortality. Recent studies in <em>Anolis</em> lizards report hurricane-induced phenotypic shifts and selection favoring morphological variation related to clinging performance. Although it is difficult to observe organismal responses during extreme events in nature, we can experimentally simulate the high-speed winds associated with hurricanes to evaluate the putative mechanism underlying observed patterns of natural selection.</p> <p>2. In this study, we used two laboratory experiments to better understand the clinging performance and behavior of <em>Anolis</em> lizards when experiencing hurricane-force winds. We assessed the physical ability of lizards when using the combined function of their claws, limbs, toepads, and other traits to resist forces pulling them off a perch. We also evaluated the combination of this physical clinging ability of lizards and their behavioral responses to avoid being blown off a perch during high winds. We assessed behavior that could decrease exposure of lizards to wind and increase their clinging ability.</p> <p>3. Clinging force measurements revealed variation in performance among species and substrates not reflected in clinging times for lizards experiencing hurricane-force winds, revealing the importance of behavior when experiencing high winds. The most arboreal species (<em>A</em>. <em>carolinensis</em>) had substantially longer clinging times on rough substrates compared to the other species, presumably due to its larger toepads for increased clinging as well as its shorter limbs that reduced drag.</p> <p>4. Under high-speed winds, lizards commonly shifted to the more protected leeward side of dowels, especially on broad and rough substrates, presumably to reduce exposure. This reveals how behavior can mediate factors influencing clinging ability during hurricanes and, in conjunction with ecologically relevant variation in morphology and substrate properties, contribute to clinging performance.</p> <p>5. Our experiments reveal that behavior strongly influences clinging performance during high winds beyond that predicted by physical traits alone. Thus, microhabitat selection of perches and the position of a lizard on its perch during a hurricane will likely have important consequences for clinging performance. This may alter how selection acts on morphological traits and influence the susceptibility of different species to these extreme weather events.</p>

Data for: Contextual behavioral interactions of common side-blotched lizards (Uta stansburiana)
<p>These datasets are a summary of all interactions between Common Side-blotched Lizards (Uta stansburiana) and other species. The first (AdultUtaInteractions) contains rows that result from individual replicate interactions during focal-animal observations in two different years. Data include date of observation, time of focal's start, ID of Common Side-blotched Lizard observerd, its sex, and body size as well as the identification of the species with which this individual interacted and its sex. Following this the are the characteristics of the focal animal during 5 min. periods before (pre) and during/following (post) an interaction for the focal animal's perch (height and diameter), movement, and displays (headbobs) as their sum during those 5-min. periods and as the difference (post less pre). Following this are interaction intensity scores (0=no interaction, 5=most intense interaction), intensity scores with initiation coded by sign (positive values as initiated by focal animal, negative as by other individual). Next are display body postures recoded during the interaction (used post-interaction only) scored as N=none or identifying the species performing the posture. These are repeated as effect codes (0=no posture, 1=posture used during interaction). Finally, a notes column indicates any noted details of the interaction.</p> <p>The other dataset (DailyInteractionsSums&Rates) contains a summary of each day's data collection during this study over the two years of study (JD=days since Jan. 1). Decimal min. contains the total time of focal observations performed on that day. Following this are columns containing the count of intrasexual and intersexual interactions as well as the count of intraspecific and interspecific interactions observed on that day. There are then two columns containing the count of events occurring between Uta stansburiana (U.s.) and Sceloporus occidentalis (S.o.) and between Uta and Sceloporus graciosus (S.g.). Next time is calculated as a decimal hours basis before the count of interactions per hour are calculated for each of the previous categories of counts.</p>
