“…Overall, although occasional nocturnal activity (de Mesquita, Passos & Rodrigues, 2012) or prolonged switches to nocturnal and cathemeral patterns have been reported for squamates (Seifan et al ., 2010; Sperry et al ., 2013; Mata‐Silva et al ., 2018; Lara Resendiz, 2019; Mukherjee & Mohan, 2022), there remains a need for further studies of nocturnal thermoregulation strategies of squamates and their relationship with daytime thermoregulation.…”

Nocturnal temperatures are increasing at a pace exceeding diurnal temperatures in most parts of the world. The role of warmer nocturnal temperatures in animal ecology has received scant attention and most studies focus on diurnal or daily descriptors of thermal environments' temporal trends. Yet, available evidence from plant and insect studies suggests that organisms can exhibit contrasting physiological responses to diurnal and nocturnal warming. Limiting studies to diurnal trends can thus result in incomplete and misleading interpretations of the ability of species to cope with global warming. Although they are expected to be impacted by warmer nocturnal temperatures, insufficient data are available regarding the night‐time ecology of vertebrate ectotherms. Here, we illustrate the complex effects of nocturnal warming on squamate reptiles, a keystone group of vertebrate ectotherms. Our review includes discussion of diurnal and nocturnal ectotherms, but we mainly focus on diurnal species for which nocturnal warming affects a period dedicated to physiological recovery, and thus may perturb activity patterns and energy balance. We first summarise the physical consequences of nocturnal warming on habitats used by squamate reptiles. Second, we describe how such changes can alter the energy balance of diurnal species. We illustrate this with empirical data from the asp viper (Vipera aspis) and common wall lizard (Podarcis muralis), two diurnal species found throughout western Europe. Third, we make use of a mechanistic approach based on an energy‐balance model to draw general conclusions about the effects of nocturnal temperatures. Fourth, we examine how warmer nights may affect squamates over their lifetime, with potential consequences on individual fitness and population dynamics. We review quantitative evidence for such lifetime effects using recent data derived from a range of studies on the European common lizard (Zootoca vivipara). Finally, we consider the broader eco‐evolutionary ramifications of nocturnal warming and highlight several research questions that require future attention. Our work emphasises the importance of considering the joint influence of diurnal and nocturnal warming on the responses of vertebrate ectotherms to climate warming.

“…Indeed, habitat in Phelsuma geckos is generally understudied, although previous studies have found: 1) evidence of habitat partitioning in their native ranges (Harmon et al 2007;Bungard et al 2014;Hagey et al 2016;Noble et al 2011), 2) interaction between introduced and native Phelsuma in the Comoros Islands (Augros et al 2018), and 3) that native geckos may impact introduced Phelsuma (Cole and Harris 2011). Within Hawai'i, investigators have also found that P. laticauda may be expanding their temporal niche, foraging near arti cial lights after dark (Seifan et al 2010). Regardless of whether ecological shifts in Hawai'i's introduced Phelsuma are driven by anole presence, they might be predicted to drive plastic or evolutionary changes in ecomorphology.…”

Phenotypic change plays diverse and crucial roles in biotic invasion, but most studies of invasions focus on individual species. To compare ecomorphological changes among co-invading species with overlapping native niches, we examined three lizards on the island of O‘ahu: (Anolis carolinensis, A. sagrei, Phelsuma laticauda). Using specimens from three decades of unfolding invasions obtained from museum collections and the field, we quantified temporal shifts in three ecologically relevant traits: snout vent length (SVL), forelimb-, and hindlimb-length (limb lengths relative to SVL). We found unique patterns of phenotypic change in each species as well as sex-specific changes within species: 1) both anole species increased in SVL since the 1980s, 2) forelimb length increased in Phelsuma females and in both sexes in A. carolinensis, and 3) relative hindlimb length increased in Phelsuma (both sexes) and decreased in A. sagrei (both sexes). The observed changes involve ecomorphological traits that are feasibly consequential to invasion dynamics. Our study illustrates how museum- and field-based research can be integrated to document nuanced temporal patterns in the phenotypes of co-invading species that share similar niches in their native ranges; it also raises important questions about the underlying process(es) driving species- and sex-specific change in co-invaded systems.

Phenotypic change plays diverse roles in species’ colonization, but most invasion studies target single species. To compare ecomorphological changes among co-invading species with overlapping niches, we examined three lizards on the island of O‘ahu (Anolis carolinensis, A. sagrei, Phelsuma laticauda). Using specimens from three decades of unfolding invasions obtained through museum collections and contemporary field work, we quantified shifts in three traits: snout vent length (SVL), forelimb-, and hindlimb-length (limb lengths relative to SVL). We hypothesized that competition among these three species has led to ecological shifts that will be detectable through morphological change. Overall, we found that unique patterns of phenotypic change were both species-specific and sex-specific within species: (1) male A. sagrei, female A. carolinensis, and male P. laticauda increased in SVL and (2) relative hindlimb length increased in female A. carolinensis since the 1980s. The observed changes involve traits that may be consequential to invasion dynamics. This study illustrates how museum- and field-based research can be integrated to document nuanced temporal patterns in the phenotypes of co-invading species that share similar niches in native ranges, raising questions about the underlying process(es) driving species- and sex-specific change in co-invaded systems.
