High temperatures amplify aggressiveness of an invasive lizard toward a native congener
Invasive species cause major disturbances to endemic wildlife and often displace native species. Behavioral aggression can contribute to invasive species success, but little is known about how temperature and aggression interact. We tested for effects of temperature on interspecific aggression between the invasive brown anole lizard (Anolis sagrei) and a native congener, the green anole (A. carolinensis). Anolis sagrei displaces A. carolinensis from perch sites in sympatry, which is hypothesized to result at least in part from higher levels of aggression. We tested hypotheses about the temperature-dependence of interspecific aggression across five ecologically relevant temperature regimes that span cool spring to hot summer conditions. Additionally, we tested whether the presence of A. sagrei disrupts A. carolinensis thermoregulation. The invasive Anolis sagrei was more aggressive than A. carolinensis in all temperature regimes. In addition, the difference in aggression between the species was greatest at high temperatures. In contrast, we found little evidence that A. carolinensis thermoregulation is affected by A. sagrei. Our results indicate that the effects of an invasive lizard on a native competitor may be facilitated by high levels of aggression that could be amplified with rising temperatures. Overall, our results are consistent with aggression facilitating invasive species success, and that the effect can be amplified under climate change.
期刊介绍:
The Journal of Thermal Biology publishes articles that advance our knowledge on the ways and mechanisms through which temperature affects man and animals. This includes studies of their responses to these effects and on the ecological consequences. Directly relevant to this theme are:
• The mechanisms of thermal limitation, heat and cold injury, and the resistance of organisms to extremes of temperature
• The mechanisms involved in acclimation, acclimatization and evolutionary adaptation to temperature
• Mechanisms underlying the patterns of hibernation, torpor, dormancy, aestivation and diapause
• Effects of temperature on reproduction and development, growth, ageing and life-span
• Studies on modelling heat transfer between organisms and their environment
• The contributions of temperature to effects of climate change on animal species and man
• Studies of conservation biology and physiology related to temperature
• Behavioural and physiological regulation of body temperature including its pathophysiology and fever
• Medical applications of hypo- and hyperthermia
Article types:
• Original articles
• Review articles
