“…Although some studies indicate that C. antarcticus is highly susceptible to desiccation, due to their rapid water loss at high relative humidities (Elnitsky et al, 2008; Hayward et al, 2001), we found that C. antarcticus had higher desiccation tolerance than P. minuta . These results contrast with published literature on invasive species, which tend to show that alien species have on average higher tolerance to desiccation than native species (Chown et al, 2023; Phillips et al, 2020; da Silva et al, 2020).…”

“…Differences in cuticle coloration between specimens could also be affecting desiccation tolerance, since studies with Drosophila species have observed greater tolerance in darker individuals than in lighter ones (Parkash et al, 2008).

The extreme low humidity and temperatures in Antarctica make it one of the harsher areas for life on our planet. In a global change context, environmental barriers that prevented the arrival of alien species in Antarctica are weakening. Deception Island, one of the four active volcanoes of Antarctica, is especially vulnerable to the impacts of alien species. Geothermal areas (GA) in this Island offer unique microclimatic conditions that could differentially affect native and alien soil arthropods. Here we explore the desiccation tolerance of a native (Cryptopygus antarcticus) and an alien (Proisotoma minuta) springtail (Collembola) species to these extreme environmental conditions. GA and non‐geothermal areas (NGA) were selected to evaluate intra‐ and interspecific variation in desiccation tolerance. Populations of P. minuta from GA had greater desiccation tolerance than populations from NGA. However, desiccation tolerance of C. antarcticus did not differ between GA and NGA. This native species had greater desiccation tolerance than the alien P. minuta, but also greater body size. Our findings show that the alien P. minuta responds differently to environmental conditions than the native C. antarcticus. Furthermore, body size may influence desiccation tolerance in these two springtail species.

Functional trait–based mediation of animal invasions is only now developing, yet it is already showing as much promise as the approach has for plant invasion biology. Here, we provide a theory-founded examination of functional trait-based ecology with respect to animal invasions, together with a review of the empirical research. Recent developments in the scaling of traits to ecosystems, along with the frameworks for invasion ecology, provide a powerful foundation for investigations. Despite growing empirical research in this field, interspecific comparisons incorporating comparative phylogenetic approaches remain uncommon, and those examining assemblages are even more so. Despite the importance of time since introduction, it is rarely included in studies. Broad environmental tolerances, life history traits associated with fast growth or greater reproduction, and in some cases, greater phenotypic plasticity of traits, mediate the success of animal alien species at various stages of invasion, although introduction effort remains one of the most important factors affecting success. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 54 is November 2023.
