“…By contrast, the “compensation hypothesis” posits that individuals with higher maintenance costs have less energy surplus to allocate to other physiological functions, resulting in trade-offs with growth, reproduction, and immune defense [1, 50, 51]. Our metabolic rate data from invasive P. antipodarum support the compensation hypothesis, especially when taken together with previous studies of life-history trait variation in P. antipodarum [27]. The ability of invasive snails to maintain a low metabolic rate at higher temperature means that out of a finite organismal energy budget, a lower proportion of metabolic energy is allocated for routine or maintenance metabolism at higher temperatures in invasive snails.…”

“…The genetic diversity observed in Europe is low enough to suggest post-invasion diversification [26, 47] rather than the multiple separate origins of clones that the New Zealand data indicate [24, 48]. Outside of the diversification linked to mutation post-invasion, invasive lineages of P. antipodarum seem to represent a subset of native variation that is beneficial in the setting of invasion [27]. Indeed, both North American and European invasive lineages harbor mtDNA haplotypes common on the North Island of New Zealand [23, 47].…”

“…To contrast these native asexual lineages with invasive lineages, we acquired triploid asexual North American invasive lineages from Center County (PA), Columbia River (WA), Muscureteang River (NJ), Snake River (ID), Broadman River (MI), the widely distributed US1 lineage, and a lineage from the "GeraardsB" European population [Geraardsbergen (Belgium)] detailed in Donne et al (2020) [27]. A total of 90 triploid lineages were isolated from seven New Zealand lakes, and seven triploid lineages were isolated from the six US collection sites and the Belgian collection site.…”

“…characterized by very low genetic diversity in its invaded range [25][26][27][28]. Only two mitochondrial haplotypes have been identified in Europe, whereas more than 50 mitochondrial haplotypes have been characterized in the native New Zealand lakes [24,28,46,47].…”

Metabolic rate is an emergent organismal trait that integrates energetic costs of living and influences species distributions and response to climate change. For ectotherms, metabolic rate is likely shaped by interactions between mitochondrial and nuclear genomes and environmental temperature. Variation in reproductive mode (e.g., asexual vs. sexual reproduction) can enhance or interfere with cross-generational transmission of these interactions, with implications for evolutionary responses to selection on standing genetic variation for metabolism-related traits. We leveraged known patterns of mitochondrial-nuclear discordance in a global invader, the snail Potamopyrgus antipodarum, to measure thermal plasticity of metabolic rate in invasive vs. native asexual lineages that combined multiple mitochondrial haplotypes with nuclear genomic variation from distinct lake populations. Native lineages harbored significant mitochondrial-nuclear variation for metabolic plasticity, with some genotypes maintaining low metabolic rates at high temperature. Invasive lineages contained only a small subset of this variation, with non-plastic and lower metabolic rates relative to native lineages at high temperature. Together, these data indicate that mitochondrial-nuclear-environment interactions contribute to variation in the metabolic rate of asexual lineages. Our results also demonstrate that invasive lineages have metabolic phenotypes that could facilitate successful colonization of aquatic habitats via decreased maintenance metabolism under high temperatures.

“…In particular, we have shown that invasive and native conspeci cs might display differential growth responses to population density. These observations are especially intriguing in light of other evidence that invasive P. antipodarum have distinct life-history trait values (Donne et al 2022). One potential implication of these results is that invasive P. antipodarum may be more likely to persist through the colonization and establishment stages of invasion via growth rate insensitivity to population density.…”

Species invasion can negatively affect natural ecosystems by causing biodiversity loss, changing nutrient cycling processes, and altering trophic webs. Understanding how and why some species or lineages become invasive is critically important to preventing and controlling invasions. We address whether key life history traits of invasive vs. native lineages – here Potamopyrgus antipodarum - differ in response to environmental stressors that could determine the outcome of invasions. We focus here on population density, which is a fundamental characteristic of all populations and to which native lineages of P. antipodarum are very sensitive. This New Zealand freshwater snail successfully invaded Europe in the 19th century and is a more recent invader in North America. In just a few decades, invasive populations of P. antipodarum have spread across much of North America, with detrimental effects for local food webs and native species. We quantified individual growth rate and embryo number in P. antipodarum from multiple distinct native range and invasive lineages cultured from the juvenile stage across three different population density treatments. The growth of native but not invasive lineages decreased as density increased, and reproduction in invasive but not native snails was positively affected by increased density. These results are consistent with a scenario where differential sensitivity to population density could help explain why some lineages become invasive while others do not. Our findings also align with previous studies that show that invasive lineages of P. antipodarum exhibit a relatively wide range of tolerance to environmental stressors.

Understanding how and why some species or lineages become invasive is critically important for effectively predicting and mitigating biological invasions. Here, we address an important unanswered question in invasion biology: do key life‐history traits of invasive versus native lineages within a species differ in response to key environmental stressors? We focus on the environmental factor of population density, which is a fundamental characteristic of all populations, and investigate how changes in density affect native versus invasive Potamopyrgus antipodarum (New Zealand mudsnail). P. antipodarum has invaded 39 countries and detrimentally affects invaded environments. Previous studies of native and invasive populations and from laboratory experiments have demonstrated that growth and reproduction of P. antipodarum is sensitive to population density, though whether and how this sensitivity varies across native versus invasive lineages remains uncharacterized. We quantified individual growth rate and reproduction in P. antipodarum from multiple distinct native and invasive lineages across three different population density treatments. The growth of native but not invasive lineages decreased as density increased. There was no differential effect of density treatment on embryo production of invasive versus native snails, but a significantly higher proportion of snails were reproductive in high density compared to intermediate density for invasive lineages. In native lineages, there were no significant differences in the relative frequency of reproductive snails across density treatments. While the extent to which these results from our laboratory study can be extrapolated to the more complex natural world remain unclear, our findings are consistent with a scenario where differential sensitivity to population density could help explain why some lineages become successful invaders. Our findings also align with previous studies that show that invasive P. antipodarum lineages exhibit a relatively wide range of tolerance to environmental stressors.
