Table 1 Components of the systematic map

From: Evidence of the environmental impact of noise pollution on biodiversity: a systematic map protocol

Population All wild species
Exposure All anthropogenic noises (e.g. traffic noise, urban noises, aircraft, industry, ships, etc.) in all environments and media (terrestrial, aquatic, aerial), for all contexts and origins of the noise (spontaneous or recorded, in situ or in laboratory, etc.) and for all types of sound (including ultrasounds, infrasounds, etc.)
Comparator Conditions before and after exposure to noise (temporal comparator) or ecosystems exposed and not exposed to noise (spatial comparator)
Outcomes All outcomes related to the studied population, including but not restricted to biology/physiology (e.g. heart rate), use of space (e.g. species distribution, individual movements), intra- and interspecific communication (e.g. song frequencies), species reproduction, ecosystem composition (e.g. species richness, abundance)
