Signal Ecology: Foundations of a Substrate-Level Science of Signals and Drift

Signal Ecology introduces a substrate‑neutral ecological framework for understanding how signals behave, stabilize, drift, and interact across heterogeneous environments. The paper formalizes the dynamics of signal species, ecological manifolds, interaction laws, and stability conditions required for meaning‑preserving systems. Signal Ecology defines the ecological layer of the DSLO discipline, describing how signals occupy, traverse, and modify ecological space while maintaining coherence under transformation. This work establishes the ecological foundation for meaning physics and provides the cross‑domain structure needed to analyze semantic stability in physical, biological, human, machine, and organizational systems.
