Biogeokemiallisten

Biogeokemiallisten is a term used in some Scandinavian-language contexts to denote an inventory or catalog of biogeochemical processes that govern the movement of chemical elements through living and nonliving components of the Earth system. The concept sits at the intersection of biology, geology, chemistry, and ecology, and encompasses how organisms influence, and are influenced by, the cycling of elements such as carbon, nitrogen, phosphorus, sulfur, and oxygen across the atmosphere, hydrosphere, lithosphere, and biosphere.

Etymology and usage: The word is a compound of bio-, geo-, chem- (chemistry), and listen (list). In English-language sources, the term is rarely used; the concept is generally expressed as “biogeochemical cycles” or “biogeochemistry inventory.”

Components and scope: A biogeokemiallisten may be organized as a structured catalog of reservoirs, fluxes, and mediators. It typically includes major cycles (carbon, nitrogen, phosphorus, sulfur, water/oxygen) and may add trace elements. It emphasizes pathways such as photosynthesis, decomposition, mineralization, mineral weathering, microbial metabolism, redox reactions, and anthropogenic inputs.

Applications and significance: The concept is used in education and research to map nutrient flows, assess ecosystem health, model responses to climate change, and guide environmental management. It can be represented as tables, graphs, or databases and may integrate field measurements with laboratory analyses and geochemical modeling.
