“…A few studies have analysed effects of seasonality on taxonomic diversity in Neotropical lizard assemblages (Fitzgerald et al 1999;Andrade et al 2013;Muniz et al 2016;Passos et al 2016), with most of them finding a similar lack of an effect of seasonality on species richness. In contrast, in temperate latitudes where seasonal environmental changes do limit activity and reproduction in lizards (James & Shine 1985), species diversity tends to vary among seasons (Peña-Joya et al 2020). Indeed, lower temperatures during winter may prevent the activity of many species of lizards (McConnachie et al 2007;Liz et al 2019).…”

“…Despite of lower extension area of Cerrado forested formations (Furley 2006), the greatest vegetation heterogeneity found in these formations (Pinheiro & Durigan 2012;Ferreira et al 2017) should allow lizard species to use a greater number of distinct ecological niches, as observed in studies with these organisms in other habitats (Berriozabal-Islas et al 2017;Peña-Joya et al 2020;Palmeirim et al 2021). This differentiation of the ecological niche should contribute to reduce interspecific competition (Mouchet et al 2010;Pavoine & Bonsall 2011) and promote the increase in traits diversity among species.…”

“…Lizard assemblages vary in species richness, abundance and composition in the diverse habitats of the Cerrado (Nogueira et al 2005(Nogueira et al , 2009Vitt et al 2007;Novelli et al 2012), mainly due to the presence of several specialist species (Vitt 1991;Vitt et al 2007;Nogueira et al 2009), with traits that vary according to the habitats and microhabitats used (Lanna et al 2021). Lizard assemblage responses to seasonality can differ with habitat (Peña-Joya et al 2020). In other Neotropical grasslands and savannas, studies have found contrasting results, such as greater lizard abundance during dry season (Muniz et al 2016) and also absence of influence of seasonal variation on the species abundance and richness (Passos et al 2016).…”

One of the core issues in community ecology is the understanding of mechanisms that determine community structure. In this study, we examine how two structurally distinct habitats (campo sujoa grassy savanna habitat with low shrubby coverand seasonal semi-deciduous forest) and distinct hydrological seasons (dry and rainy) influence the taxonomic, functional and phylogenetic diversity of lizard assemblages in a savanna area in the Brazilian Cerrado. We used pitfall traps to sample lizards from May 2000 to February 2002. To quantify spatio-temporal changes in the lizard assemblages, we used parameters of taxonomic (species richness -SR), functional (functional diversity -SES.FD, functional redundancy -FR and functional dispersion -FDis), and phylogenetic diversity (phylogenetic species richness -PSR and phylogenetic species variability -PSV). We also estimate functional and phylogenetic structure of the assemblages in each habitat during dry and rainy seasons. We recorded 182 lizards distributed among 14 species. Species composition differed among habitat types, but did not differ seasonally within habitats. SES.FD, FDis, and FR also differed among habitat types but not among seasons, with SES.FD and FDis being greater in seasonal semi-deciduous forest, while FR was greater in campo sujo. SR, PSR, and PSV were not influenced by the factors analysed. The lizard assemblage of campo sujo was functionally clustered in the dry season and phylogenetically clustered in the rainy season. These results demonstrate that differences among habitat types and seasons are important in shaping the taxonomic, functional, phylogenetic diversity and structure of lizard assemblages in the savanna area studied. Our study also demonstrates the importance of using different measures of diversity to obtain a better understanding on the mechanisms that influence the lizard assemblages in a highly seasonal environment.

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.
