“…This physiological response supports more effective escape from fire ants (Trompeter & Langkilde, 2011) and primes lizards to flee from future attacks (Langkilde, Thawley, & Robbins, 2017), thus supporting observed adaptive shifts in antipredator behavior.…”

“…Our results show that adaptive changes to novel pressures can occur simultaneously across multiple pathways and encompass multiple traits (morphology, physiology, and behavior). The adaptive values of trait shifts are linked, as changes in stress responsiveness and hindlimb length support increased flight behaviors (Langkilde, 2009;Langkilde et al, 2017;Trompeter & Langkilde, 2011), allowing an integrated organismal response to a single novel biotic threat. Evidence suggests that heritable variation may underlie some trait shifts in fence lizards, as limb length in Sceloporus is heritable (Langkilde, 2009;Tsuji, Huey, Berkum, Garland, & Shaw, 1989) and changes in response to selection in lizards (Calsbeek & Irschick, 2007) (Brommer, Hanski, Kekkonen, & Väisänen, 2015;Gardner et al, 2009;Huey et al, 2005;Umina, Weeks, Kearney, Mckechnie, & Hoffmann, 2005).…”

Understanding the processes driving formation and maintenance of latitudinal clines has become increasingly important in light of accelerating global change. Many studies have focused on the role of abiotic factors, especially temperature, in generating clines, but biotic factors, including the introduction of non‐native species, may also drive clinal variation. We assessed the impact of invasion by predatory fire ants on latitudinal clines in multiple fitness‐relevant traits—morphology, physiological stress responsiveness, and antipredator behavior—in a native fence lizard. In areas invaded by fire ants, a latitudinal cline in morphology is opposite both the cline found in museum specimens from historical populations across the species’ full latitudinal range and that found in current populations uninvaded by fire ants. Similarly, clines in stress‐relevant hormone response to a stressor and in antipredator behavior differ significantly between the portions of the fence lizard range invaded and uninvaded by fire ants. Changes in these traits within fire ant‐invaded areas are adaptive and together support increased and more effective antipredator behavior that allows escape from attacks by this invasive predator. However, these changes may mismatch lizards to the environments under which they historically evolved. This research shows that novel biotic pressures can alter latitudinal clines in multiple traits within a single species on ecological timescales. As global change intensifies, a greater understanding of novel abiotic and biotic pressures and how affected organisms adapt to them across space and time will be central to predicting and managing our changing environment.

“…Fourth, we searched for evidence that the Hudson ecosystem has developed resistance to the Dreissena invasion over time, so that per capita Dreissena impacts have declined. There is a persistent idea in invasion ecology that ecosystems might become more resistant to an invader over time as species already in the ecosystem develop morphological or behavioral defenses against the invader, incorporate the invader into their diets, and so on (e.g., Carlsson et al 2009;Strayer 2012;Iacarella et al 2015;Langkilde et al 2017), or as new enemies of the invader arrive in the ecosystem.…”

Non-native species are among the most important drivers of the structure and function of modern ecosystems. The ecological impacts of a non-native species ought to depend on the size and characteristics of its population, but the exact nature of this population-impacts relationship is rarely defined. Both the mathematical form of this relationship (e.g., linear, exponential, and threshold) and the attributes of the invading population (e.g., density, biomass, and body size) that most efficiently describe its impacts could vary greatly across invaders, ecosystems, and ecological variables. Knowing the shape of this relationship could improve management and help to infer mechanisms of interaction between the invader and ecosystem. We used a long-term data set on the invasion of the Hudson River ecosystem by two species of Dreissena (the zebra mussel, Dreissena polymorpha, and the quagga mussel, Dreissena rostriformis) to explore the shape of the population-impacts relationship for selected ecological variables, including seston, phytoplankton, and several taxa of zooplankton. Most population-impacts relationships appeared to follow a negative exponential form, but we also found apparent thresholds and scatterplots for some variables. Including information on the traits of Dreissena (body size and filtration rate) often substantially improved models of impacts. We found only slight evidence that the resistance of the Hudson River ecosystem to the Dreissena invasion might be increasing over time. Our results suggest important refinements to widely used conceptual models of invasive species impact, and indicate that defining the population-effects relationship will be essential in understanding and managing the impacts of non-native species.

“…It follows that, for species with negative frequency-dependent sexual selection, phenotypically diverse populations can produce more offspring at a reduced risk of predation. As invasive species frequently encounter novel predators, these advantages are likely to be critical to invasive success (Langkilde et al, 2017). But negative-frequency dependent selection is not exclusively maintained by sexual selection as seen for Trinidadian guppies.…”

The effect of phenotypic heterogeneity on behaviours linked to invasive success

Every year thousands of species are transported and introduced to novel ecosystems around the globe by human activities (Havel et al., 2015;Hulme, 2009;Pimentel et al., 2004). Despite being considered an issue for biodiversity and conservation, the majority of introduced, non-native species fail to establish, or establish without becoming invasive (Holway & Suarez, 1999;Milbau & Stout, 2008).Nonetheless, even a small proportion of successful invasive species can become problematic and lead to severe ecological and economic impacts (Carter et al., 2021;Clavero & Garcia-Berthou, 2005;Park, 2004). Given the difficulty of eradicating invasive species, it is critical that we can accurately identify which species and/or populations pose the greatest risk of becoming problematic invasive species (Holway & Suarez, 1999). While the economic and ecological costs of invasive species are unequivocal, current ability to forecast species' invasive propensity remains limited. Namely, our understanding of how population-level traits contribute to a species' invasive success has not been fully explored. In this study, we address this knowledge gap by investigating the contribution of phenotypic
