“…Environmental temperature varies across geographic gradients, generally decreasing with altitude and latitude (van Berkum 1988;Gvoždík 2002;Cruz et al 2005;Sunday et al 2014). In ectotherms such as lizards, regulatory behaviors and acclimatization may compensate for thermal variation within a habitat (Aubret & Shine 2010;Huey et al 2012;Block et al 2013). Hertz et al (1983) described 2 major positions on the adaptation of lizard thermal physiology, the "static" and "labile" views of thermal physiology.…”

Physiological performance in lizards may be affected by climate across latitudinal or altitudinal gradients. In the coastal dune barriers in central‐eastern Argentina, the annual maximum environmental temperature decreases up to 2°C from low to high latitudes, while the mean relative humidity of the air decreases from 50% to 25%. Liolaemus multimaculatus, a lizard in the family Liolaemidae, is restricted to these coastal dunes. We investigated the locomotor performance of the species at 6 different sites distributed throughout its range in these dune barriers. We inquired whether locomotor performance metrics were sensitive to the thermal regime attributable to latitude. The thermal performance breadth increased from 7% to 82% with latitude, due to a decrease in its critical thermal minimum of up to 5°C at higher latitudes. Lizards from high latitude sites showed a thermal optimum, that is, the body temperature at which maximum speed is achieved, up to 4°C lower than that of lizards from the low latitude. At relatively low temperatures, the maximum running speed of high‐latitude individuals was faster than that of low‐latitude ones. Thermal parameters of locomotor performance were labile, decreasing as a function of latitude. These results show populations of L. multimaculatus adjust thermal physiology to cope with local climatic variations. This suggests that thermal sensitivity responds to the magnitude of latitudinal fluctuations in environmental temperature.

“…For example, the native sand lizard species Liolaemus wiegmannii changed its basking pattern after the spread of acacia trees Acacia longifolia in Argentina, which produce significantly more shade than the native vegetation (Block, Stellatelli, García, Vega, & Isacch, 2013).…”

“…Invasive species commonly have different environmental characteristics in the invaded range to cope with, but also native species can be forced to change their behaviour due to invasions. For example, the native sand lizard species Liolaemus wiegmannii changed its basking pattern after the spread of acacia trees Acacia longifolia in Argentina, which produce significantly more shade than the native vegetation (Block, Stellatelli, García, Vega, & Isacch, 2013).…”

“…For example, some individuals of garden skinks climbed invasive vines when ground-level basking sites became scarce owing to increased shading [48], whereas lizards in another comparison restricted activity to open micro-habitats similar to those they inhabit in natural areas [40]. In two independent comparisons, lizards in invaded landscapes were active for shorter periods or spent more time basking ( [28,48]; figure 1). These studies measured body temperatures in the field or in the laboratory, but assessments can also rely on individual-based models that simulate the body temperature of virtual individuals moving through landscapes with known operative temperature distributions [41,42].…”

“…Changes in thermal quality caused by plant invasions are expected to be largest when the alien plants present novel growth forms or structural features relative to the dominant native vegetation [9,26]. For example, larger size and faster-growing alien trees can cause reductions in light and temperature in shrubland habitats [27,28], and those with extended phenology can lengthen thermal effects beyond the growing season of native vegetation [29].…”

A growing body of research demonstrates the impacts of invasive alien plants on native animals, but few studies consider thermal effects as a driver of the responses of native organisms. As invasive alien plants establish and alter the composition and arrangement of plant communities, the thermal landscapes available to ectotherms also change. Our study reviews the research undertaken to date on the thermal effects of alien plant invasions on native reptiles, amphibians, insects and arachnids. The 37 studies published between 1970 and early 2019 portray an overall detrimental effect of invasive plants on thermal landscapes, ectothermic individuals' performance and species abundance, diversity and composition. With a case study of a lizard species, we illustrate the use of thermal ecology tools in plant invasion research and test the generality of alien plant effects: changes in thermoregulation behaviour in invaded landscapes varied depending on the level of invasion and lizard traits. Together, the literature review and case study show that thermal effects of alien plants on ectotherms can be substantial albeit context-dependent. Further research should cover multiple combinations of native/invasive plant growth forms, invasion stages and ectotherm traits. More attention is also needed to test causality along the chain of effects from thermal landscapes to individuals, populations and communities.
