littercentric

Littercentric is an adjective used in ecology and related disciplines to describe a focus on litter, particularly the leaf litter layer, as a central component of ecosystem processes. In this sense, studies described as littercentric emphasize the role of plant detritus in nutrient cycling, soil structure, and energy flow rather than focusing primarily on living vegetation or higher trophic levels.

Origin and usage: The term combines litter (dead plant material on the forest floor) with centric (derived from the notion of center). It is used mainly in ecological and soil science literature to denote a perspective or methodology that places litter inputs, decomposition, and litter-layer interactions at the core of analyses.

Applications: Littercentric approaches examine litter production (litterfall), quality (carbon-to-nitrogen ratio, lignin content), decomposition rates, microbial and faunal activity within the litter layer, and how litter influences soil moisture, habitat provision, and carbon storage. It can be contrasted with canopy-centric or productivity-centric approaches that emphasize living vegetation or primary production.

In other domains: Some writers use littercentric terminology metaphorically to describe cultural or urban studies that focus on discarded objects or waste streams as central elements of analysis.
