A growing body of research demonstrates the impacts of invasive alien
plants on native animals, but few studies consider thermal effects as a
driver of the responses of native organisms. As invasive alien plants
establish and alter the composition and arrangement of plant communities,
the thermal landscapes available to ectotherms also change. Our study
reviews the research undertaken to date on the thermal effects of alien
plant invasions on native reptiles, amphibians, insects and arachnids. The
37 studies published between 1970 and early 2019 portray an overall
detrimental effect of invasive plants on thermal landscapes, ectothermic
individuals' performance and species abundance, diversity and
composition. With a case study of a lizard species, we illustrate the use
of thermal ecology tools in plant invasion research and test the
generality of alien plant effects: changes in thermoregulation behaviour
in invaded landscapes varied depending on the level of invasion and lizard
traits. Together, the literature review and case study show that thermal
effects of alien plants on ectotherms can be substantial albeit
context-dependent. Further research should cover multiple combinations of
native/invasive plant growth forms, invasion stages and ectotherm traits.
More attention is also needed to test causality along the chain of effects
from thermal landscapes to individuals, populations and communities.
