Environmental stress mediates trophic cascade strength and resistance to invasion

  title={Environmental stress mediates trophic cascade strength and resistance to invasion},
  author={Brian Cheak Shing Cheng and Edwin D Grosholz},
Although much attention has focused on the drivers of trophic cascade strength among systems (e.g., habitat type, body size, predator, and prey thermy) comparatively little is known of how trophic cascades change within systems, especially with respect to gradients in environmental stress. To address this, we measured the strength of a trophic cascade across an estuarine stress gradient and tested the predictions of “consumer stress model” that suggests sensitivity to stress is greater in… CONTINUE READING
