“…Previous studies indicated that higher soil temperature can help juveniles to maintain their body temperature, and thus the normal metabolism (Huey & Kingsolver, 1989; Ohlberger, 2013). Moreover, these environmental conditions can provide juveniles with sufficient food resources such as beetles and spiders (Maia‐Carneiro et al., 2017; Sutherland, 2011). Abundant rocks were associated with sufficient refuges for juveniles, reducing the risk of being predation.…”

Exploring the microhabitat determinants of organisms distribution and functional traits differences can help us better understand the importance of intraspecific variations in ecological niches. Investigations on animals functional niche primarily focused on differences among species and tended to neglect the potential variability within species, despite the fact that the ecological and evolutionary importance of intraspecific variations was widely recognized. In this study, we examined the influence of microhabitat features on the intraspecific variability of the distribution and functional traits of a highest elevational distributed lizard species Phrynocephalus erythrurus. To do so, field work was conducted between July and August, 2020 and August and September, 2021 in Namtso watershed in central Xizang, China. Specifically, 11 transects were sampled for P. erythrurus individuals, which were measured for a set of 10 morphological traits. Moreover, 11 microhabitat variables that potentially affect the distribution of lizards were also measured for each transect. Our results indicated that juveniles, males, and females exhibited different functional traits, allowing them to occupy distinct functional space. The distribution of juveniles, males, and females was determined by different microhabitat variables such as illuminance and air temperature. More importantly, these variables also determined the intraspecific functional traits variability in this lizard species. All of these results supported previous claims that intraspecific traits variation should be incorporated into functional ecological studies, and diverse microhabitat features should be conserved to maintain high intraspecific diversity. Future studies can focus on the food analysis to explore the linkage between functional traits and resources utilization within animal populations.

“…The initial description of ‘ecomorphs' in Anolis (Williams, 1972; 1983) stimulated subsequent investigations of phenotypic associations with environmental parameters in several squamate lineages, including Tropidurus lizards (e.g., Brandt & Navas, 2011; Brandt et al, 2015; Grizante et al, 2010; Kiefer et al, 2007; Kohlsdorf & Navas, 2012; Kohlsdorf et al, 2001; Kohlsdorf et al, 2008; Maia‐Carneiro & Rocha, 2020; Oliveira et al, 2018). Despite identification of clear eco‐morphological associations in Tropiduridae, patterns in this family challenge the commonness of the classical Anolis ecomorphs (Tulli et al, 2016), which raises the clade as a good system to expand our knowledge of processes and mechanisms underlying phenotypic diversification in Squamata.…”

A guide to incubate eggs of Tropidurus lizards under laboratory conditions

et al. 2021

Studies in Evo-Devo benefit from the use of a variety of organisms, as comparative approaches provide a better understanding of Biodiversity and Evolution. Standardized protocols to incubate eggs and manipulate embryo development enable postulation of additional species as suitable biological systems for research in the field.In the past decades, vertebrate lineages such as Squamata (lizards, snakes, and amphisbaenians) emerged as crucial study systems for addressing topics as diverse as phenotypic evolution and climate change. However, protocols for maintaining gravid females and incubating eggs in the lab under experimental conditions are available to only a few squamate species. This resource article presents a simple incubation guide that standardizes conditions to maintain embryos of Tropidurus catalanensis (Squamata: Tropiduridae) under different experimental conditions, manipulating relevant environmental factors like temperature and humidity. We identified associated effects relating the egg incubation condition to developmental stage, incubation time, hatching success, and resulting morphotypes. Temperature and humidity play a key role in development and require attention when establishing the experimental design. Current literature comprises information for Tropidurus lizards that ponders how general in Squamata are the ecomorphs originally described for Anolis. Studies evaluating phenotypic effects of developmental environments suggest plasticity in some of the traits that characterize the ecomorphological associations described for this family. We expect that this incubation guide encourages future studies using Tropidurus lizards to address Evo-Devo questions.

Here, we report behaviors not yet known for T. catalanensis, which helps to understand how these lizards thermoregulate and evade potentially harmful interactions.…”

Lizards of the genus Tropidurus display different behaviors for thermoregulation and defense. Here, we report new displays for Tropidurus catalanensis, which helps to understand how these lizards behave. Captive individuals lifted, flattened, and buried their bodies. Flattening and upstanding the bodies allow looking larger and may discourage attacks, as well as respectively enhance and decrease the approximation and the contact of body surfaces with substrates to thermoregulate. Burying themselves into earth and sand may help lizards to avoid or escape from menaces. When we first opened the containers, the T. catalanensis were already partially covered by vermiculite, which did not allow stating if they did it in response to supposed risks of predation because perceived the movements in the room or were already buried. Tropidurus catalanensis possibly may bury themselves to avoid detection during periods of inactivity. The self-burying behavior may be useful also for thermoregulation using substrate temperatures. Tropidurus catalanensis may increase the chances of getting out safe from dangerous interactions and of effective thermoregulation by performing such behaviors. Although we discussed the behaviors on the views of defense and thermoregulation, the body lifting, the flattening, and the burying seemed have occurred in a defensive context.
