What's going to be on the menu with global environmental changes?

Area of Science:

• Ecology
• Environmental Science
• Biodiversity Research

Background:

• Anthropogenic change is rapidly altering global ecosystems and threatening biodiversity.
• Species exhibit physiological and behavioral adaptations to abiotic pressures, impacting food webs.
• Ecosystem services and species persistence are jeopardized by these global changes.

Purpose of the Study:

• To describe species' responses to global change at individual and population levels.
• To illustrate how these responses alter diet and food web dynamics.
• To emphasize the importance of diet ecology in global change research.

Main Methods:

• Analysis of physiological and behavioral responses of species.
• Investigation of diet shifts across terrestrial and marine ecosystems.
• Review of tools for studying consumption patterns and trophic interactions.

Main Results:

• Global changes lead to detectable diet shifts in species.
• Food web dynamics are altered, impacting animal communities.
• Diet data are crucial for understanding ecological responses to global change.

Conclusions:

• A holistic approach integrating diet, trophic interactions, and environmental drivers is essential.
• Understanding diet ecology is key to predicting biodiversity trends and food web responses.
• More long-term diet ecology studies are needed to identify vulnerabilities to environmental change.
