简介
- Climate change is predicted to intensify the impacts of invasive species by enhancing their performance relative to their native counterparts. However, few studies have compared the performance of invasive predators and native prey, despite the fact that non‐native predators are well known to disrupt native communities.
- The ‘trophic sensitivity hypothesis’ suggests that predators are less tolerant of increasing environmental stress than their prey, whereas the ‘tolerant invaders hypothesis’ suggests that invaders are more tolerant than native species due to selection during the introduction process. It is therefore unclear how invasive predators will respond to increasing climate stressors.
- We coupled physiological measurements (thermal tolerance, thermal optima, salinity tolerance, predation rate) with environmental time‐series data to assess the effects of warming and extreme low salinity events on non‐native …
