Ekosystemtjuter

Ekosystemtjuter is a term used in ecology to describe the aggregate acoustic activity produced within an ecosystem, including animal vocalizations, insect sounds, water and wind noise, and other audible or vibrational signals. In soundscape ecology, ekosystemtjuter refers to the characteristic aural fingerprint of a habitat, which can reflect biodiversity, behavior, and environmental conditions. The concept emphasizes ecosystem-level sound as an integrated signal rather than isolated species sounds.

Origin and scope

The term is a neologism formed from the word for ecosystem and a root meaning to emit noise or a call in several Scandinavian languages. It is used to discuss how collective acoustic emissions form a recognizable signature of an ecological community and how these signals participate in ecological processes, such as communication, foraging, mating, and predator avoidance.

Components and mechanisms

Ekosystemtjuter encompasses biotic sounds—from birds, amphibians, insects, and mammals—as well as abiotic contributors like flowing water, wind, and rain, and sometimes human-made noise. The spatial and temporal structure of these sounds can influence species interactions, habitat use, and timing of activities. Sound propagation, frequency composition, and ambient noise levels affect detectability and behavioral responses across taxa.

Measurement and applications

Researchers study ekosystemtjuter through passive acoustic monitoring, long-term sound recordings, and spectral analysis. Acoustic indices (such as richness, entropy, and complexity) provide non-invasive indicators of biodiversity, habitat quality, and seasonal change. Applications include biodiversity assessment, monitoring of ecosystem health, and evaluating the impact of climate change or human disturbance. Limitations include the challenge of linking sound patterns to specific ecological outcomes and disentangling natural from anthropogenic noise.
