Dopplerverbreeding
Dopplerverbreeding is a theoretical concept in signal ecology and evolutionary biology that examines how the Doppler effect—the change in frequency or wavelength of a wave in relation to an observer moving relative to the source—could influence the spread of communicative signals within mobile populations. The term, a German compound meaning roughly "Doppler spreading," is used to describe potential effects on which signals are detected and which traits become more common over time due to motion-related changes in signal perception.
In moving systems, relative velocity between sender and receiver shifts signal frequency and timing, which can
The concept is discussed mainly in theoretical models and discussions of signal ecology, particularly for acoustic
Dopplerverbreeding remains a speculative and debated idea with limited empirical support. Critics note the difficulty of
