Arengutaset

Arengutaset is a fictional term used in theoretical ecology to describe a hypothetical meta-ecosystem composed of several interconnected habitats linked by the dispersal of organisms and the transfer of energy and matter. The concept extends meta-ecosystem theory by emphasizing cross-habitat subsidies and feedbacks among patches, rather than treating each habitat in isolation. Etymology is constructed from roots intended to evoke connectivity and integration, and it is not tied to any particular language or region.

In character, an arengutaset comprises a network of habitat patches—such as forest, grassland, wetland, and aquatic zones—arranged so that flows of biomass, nutrients, and detritus move between them. This interconnectedness can modulate local dynamics, stabilizing populations or propagating disturbances.

Applications include academic modeling, classroom demonstrations, and scenario analysis of environmental change. Researchers use simulations to explore how altering patch attributes, connectivity, or subsidy sources affects overall system resilience, productivity, and biodiversity.

Criticism centers on the abstract nature of the construct and the challenges of parameterizing real systems to fit the model. Despite these caveats, arengutaset serves as a pedagogical tool for illustrating how spatial structure and cross-ecosystem interactions shape ecological outcomes.
