Trophic Interactions in Terrestrial Ecosystems
Summary
Trophic interactions describe the feeding relationships among organisms and underpin energy flow and nutrient cycling in terrestrial landscapes. Primary producers capture solar energy through photosynthesis, supporting herbivores that, in turn, sustain predators and decomposers. These interactions form complex food webs marked by both bottom-up influences—where plant quality and resource availability shape consumer populations—and top-down controls—where predators and parasites regulate herbivore abundance. Emerging research highlights how the interplay of species traits, habitat structure and environmental change gives rise to cascading effects that can alter community composition, ecosystem resilience and the delivery of services such as pollination and pest regulation. Advances in isotopic tracing, network analysis and experimental manipulation are revealing the dynamic nature of these links across spatial and temporal scales, emphasising their global significance for biodiversity conservation and land-use management.

Trophic Interactions in Terrestrial Ecosystems publication trend
The graph below shows the total number of articles in trophic interactions in terrestrial ecosystems across all publications each year (not limited to Nature Index journals).
Technical terms
Trophic level: A position in a food web denoting an organism’s role as producer, consumer or decomposer.
Food web: A network of feeding links showing who eats whom in an ecosystem.
Bottom-up control: Regulation of higher trophic levels driven by resource availability and plant quality.
Top-down control: Regulation of lower trophic levels by predators, parasites or pathogens.
Tri-trophic interaction: A three-level linkage among plants, herbivores and their natural enemies.
Trophic cascade: Indirect effects of predators on non-adjacent trophic levels, altering ecosystem structure and function.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
