Modeling anthropogenic noise impacts on animals in natural areas

Cross-modal impacts of anthropogenic noise on information use

Anthropogenic noise is a global pollutant, and there is rapidly accumulating evidence of impacts on a range of animal taxa [1,2]. While many studies have considered how additional noise may affect information provision and use, they have focused on the masking and consequent alteration of acoustic signals and cues; so-called unimodal effects [3]. Using field-based experimental trials on habitua...

Anthropogenic Noise as a Stressor in Animals: A Multidisciplinary Perspective

This paper could not have been written without the financial and organizational support from Dieter Paulmann and Jo Hastie respectively. Thanks are also due to 2 anonymous reviewers, whose comments on an earlier version of the manuscript greatly improved the paper. The views expressed in this paper are those of the authors alone and do not represent those of Stellwagen Bank National Marine Sanc...

Anthropogenic Impacts on Estuaries

A GIS tool for modeling anthropogenic noise propagation in natural ecosystems

SPreAD-GIS is a tool for modeling spatial patterns of anthropogenic noise propagation in natural ecosystems. SPreAD-GIS incorporates commonly available datasets on land cover, topography, and weather conditions to calculate noise propagation patterns and excess noise above ambient conditions for one-third octave frequency bands around one or multiple sound sources. User-specified noise source c...

Marine mammals and the impacts of anthropogenic noise

Sound travels with greater efficiency in water than does light, which is quickly absorbed and scattered. As a consequence, a wide variety of marine taxa use sound for communication, foraging and generally sensing their environment. Since the 1970s there has been increasing concern about the potential impacts of underwater anthropogenic noise on marine animals. Sources range from short-term coas...
