Primes

• Cross-Boundary Subsidy
  • Ecology: cross-ecosystem subsidies — marine-derived nutrients from salmon to riparian forests, seabird guano to islands, kelp wrack to beaches, stream-emerging insects to riparian birds; recipient community structure is shaped by the donor flow, and closure of the flow (dam, overfishing, guano-mining) collapses the recipient.

    This sourceFoundational theory of cross-ecosystem (allochthonous) resource subsidies in which a donor system's surplus production materially shapes recipient community structure, and closure of the flow collapses the recipient.

Domain-specific

• Detritus
  • Deposit feeders may derive much of their nutrition from microbial biomass growing on organic debris rather than directly from refractory carbon. Landscape food-web theory treats detrital movement as a spatial subsidy capable of raising productivity in a recipient habitat above what local production supports.
