Global climate change and above- belowground insect herbivore interactions

Area of Science:

• Ecology
• Climate Change Biology
• Soil Ecology

Background:

• Climate change significantly impacts ecological interactions, yet research often overlooks belowground processes.
• Existing studies predominantly focus on aboveground interactions, neglecting the critical role of soil organisms.
• There is limited empirical data on how belowground herbivores and their interactions respond to climate change.

Purpose of the Study:

• To highlight the importance of belowground fauna in understanding climate change effects on plant-mediated interactions.
• To address the scarcity of research on belowground herbivore responses to changing environmental conditions.
• To emphasize the need for integrated above- and belowground perspectives in ecological predictions.

Main Methods:

• Review of current literature on climate change impacts on ecological interactions.
• Analysis of the differential responses of aboveground and belowground organisms to environmental shifts.
• Identification of knowledge gaps concerning belowground herbivores and their ecological roles.

Main Results:

• Above- and belowground organisms exhibit distinct responses to climate change due to differing niches.
• Few studies investigate the impact of climate change on belowground herbivores and their interactions.
• Current evidence does not show a directed response in above-belowground interactions under climate change scenarios.

Conclusions:

• Belowground fauna are critical components for predicting climate change effects on plant interactions.
• Future research must incorporate belowground perspectives to accurately model ecosystem responses.
• A holistic approach considering both above- and belowground dynamics is essential for robust ecological forecasting.
