“…For example, invasive cane toads have been shown to rapidly evolve dispersal phenotypes due to spatial sorting (Shine et al 2011). Whereas certain life history and phenotypic traits of invading species may facilitate expansion by enabling them to outcompete indigenous species (Catford et al 2008;Cortes et al 2016), others may prove to be disadvantageous to the invader when environmental conditions change (Simberloff and Gibbons 2004). This suggests that a high degree of plasticity or adaptability would be beneficial for invasive species.…”

Temperature is a critical abiotic factor impacting all aspects of the biology of organisms, especially in ectotherms. As such, it is an important determinant of the potential invasive ability of organisms and may limit population expansion unless organisms can physiologically respond to changes in temperature either through plasticity or by adapting to their novel environment. Here, we studied the African clawed frog, Xenopus laevis, which has become invasive on a global scale. We compared adults from an invasive population of western France with individuals from two populations in the native range in South Africa. We measured the thermal dependence of locomotor performance in adults given its relevance to dispersal, predator escape, and prey capture. Our results show significant differences in the limits of the 80% performance breadth interval for endurance with the French population showing a left shift in its limits congruent with the colder climate experienced in France. The French invasive population was introduced only about 40 years ago suggesting a rapid shift in the thermal physiology. Given that all individuals were acclimated under laboratory conditions at 23°C for 2 months this suggests that the invasive frogs have adapted to their new environment. These data may allow the refinement of physiologically informed species distribution models permitting better estimates of future ranges at risk of invasion.

“…Our study adds to a large body of literature involving physiological comparisons of non‐native species to native ones (e.g., Cortes et al, 2016; Lehmann et al, 2015; Lockwood & Somero, 2011; Marras et al, 2015). Moreover, these results dovetail with a large‐scale meta‐analysis of the role of thermal tolerance on the invasion potential of ectotherms (Kelley, 2014).…”

Physiological evaluation of newly invasive jorō spiders (Trichonephila clavata) in the southeastern USA compared to their naturalized cousin, Trichonephila clavipes

A newly-invasive spider from east Asia, Trichonephila clavata, or "jor o spider", is spreading in the southeastern United States. Little is known about the biology or physiology of this species in this new range. Interestingly, a closely-related species in the same genus, the "golden silk spider," Trichonephila clavipes, is already successfully established in this same region over the last 160 years. The golden silk spider, which is native to the tropics, has not expanded its range beyond the southeast, likely because of thermal limitations. This investigation is to determine how the biology and physiology of T. clavata compare to T. clavipes. We reason that if their physiologies are similar, then T. clavata would be similarly confined to the southeast. We examine online records submitted to iNaturalist.org to compare seasonal distributions and timing, and we collect females to measure physiological traits that help predict environmental tolerance, including metabolic rates, cardiac functioning (heart rate) during cold-exposure, and survival during brief (2 min) below-freezing temperature. Results show the jor o spider has a shorter season than its cousin, indicating it can complete its lifecycle within a narrow period of suitable weather. It has an inherently higher metabolism (twice as high), and has a 77% higher heart rate when exposed to low temperature. Finally, jor o spiders survive better (74% compared to 50%) in a brief freeze. These findings suggest the jor o spider can exist in a colder climatic region than the southeastern USA, which can be useful information for management or planning purposes.

“…The inability of our study to detect significant differences in thermal tolerance breadth between native and invasive species may be related to the number of analysed species, since previous findings for plants (Rejmánek and Richardson 1996), epibenthic marine species (Zerebecki and Sorte 2011) and tropical and sub-Antarctic springtails (Janion-Scheepers et al 2018 have supported the Eurythermality hypothesis. However, published studies for other ectotherms such as amphibians and insects, have also found opposite results (Barahona-Segovia et al 2016, Cortes et al 2016). In the latter case, authors have made a call for caution when interpreting their results, as the trait they measured (locomotion) is produced by complex biochemical and metabolic mechanisms (the discussion by Cortes et al 2016).…”

Temperature is a primary driver to define the ecophysiological activity and performance of ectotherms. Thus, thermal tolerance limits have a profound effect in determining geographic ranges. In regions with extreme cold temperatures, lower thermal limits of species are a key physiological trait for survival. Moreover, thermal niche breadth also plays an important role in allowing organisms to withstand climatic variability and confers species with broader potential to establish in new regions. Here we study the evolution of thermal tolerance limits among Collembola (Arthropoda) and explore how they are affected by the colonization of polar environments. In addition, we test the hypothesis that globally invasive species are more eurythermal than non‐invasive ones. Critical thermal limits (CTmin and CTmax), classic measurements of thermal tolerance, were compiled from the literature and complemented with experimental assays for springtail species. Genetic data of the mitochondrial gene cytochrome oxidase subunit 1 (COI) was used to assemble a phylogeny. Our results show that polar springtails have lower CTmin and lower CTmax compared to species from temperate and tropical regions, consistent with the Polar pressure hypothesis. We found no phylogenetic signal for CTmax, but low values of phylogenetic signal for CTmin. Globally invasive species do not have significantly broader thermal tolerance breadth (CTrange) than non‐invasive ones, thus not supporting the predictions of the Eurythermality hypothesis. We conclude that polar springtails have evolved their thermal niches in order to adapt to extremely cold environments, which has led to decreasing both upper and lower thermal tolerance limits.
