Chronic anthropogenic noise in ecosystems can change avian/arthropod/plant interactions, but it is unclear how changes in herbivory pressure affects functional traits of plants. We asked how anthropogenic noise, mediated through changes in arthropod abundance, altered timing of leaf senesce, chemical composition (i.e. C/N ratios, total phenolics) and decomposition rates of leaf litter in Wyoming big sagebrush (Artemisia tridentata spp. wyo.). Additionally, we asked if changes in arthropod abundance altered secondary metabolites (i.e. monoterpenes) in foliage. We broadcasted recorded gas compressor station noise (24hrs/day) from April through October 2015 in a sagebrush steppe ecosystem of Idaho, USA. We quantified …
