Litterointia

Litterointia is a theoretical construct in ecology that describes the integrated set of processes regulating the formation, persistence, and ecological function of leaf litter layers in forest ecosystems. The term is used to capture how inputs of dead plant material, its physical and chemical properties, microbial activity, and soil–plant interactions interact to shape litter layer structure and nutrient cycling.

Its framework emphasizes four interacting components: litter input and quality (including leaf chemistry and litter morphology), decomposer communities (microbial and invertebrate), physical soil conditions (moisture, temperature, texture), and the feedbacks these elements produce on canopy dynamics and primary production through nutrient availability.

Applications and debates: Litterointia provides a lens for exploring how environmental changes such as altered precipitation, drought, or shifts in tree species composition influence carbon storage, soil fertility, and forest resilience. Critics argue that the concept is broad and overlaps with established frameworks on litter decomposition and soil food webs, and that measurable operational definitions remain challenging.

Origin and status: The term has appeared in theoretical ecology discourse since the early 2000s as a unifying concept for litter-related processes. While not universally adopted, litterointia has been used to foster interdisciplinary study linking aboveground litter production to belowground ecosystem services.
