Overview

Investigating how fatty acids link aquatic insects to terrestrial spider populations, indicating environmental impacts.

Key Points

  • Trophic connectivity increased through aquatic insect subsidies, aiding terrestrial predators like spiders.
  • Aquatic insect dispersal contributed to the fatty acid profiles of spiders, indicating cross-ecosystem linkages.
  • Analysis showed riparian habitats play important roles in severing or enhancing aquatic-terrestrial connections.
  • Increasing tree cover can enhance stream insect subsidies despite reducing primary production, benefiting local food webs.
