Beyond masking: Endangered Stephen's kangaroo rats respond to traffic noise with footdrumming... Roads and road margins on and off reserves serve as dispersal corridors and refugia for SKR and other semifossorial taxa; these areas may therefore function as ecological traps if anthropogenic roadway noise negatively affects population persistence.
Beyond masking: Endangered Stephen’s kangaroo rats respond to traffic noise with footdrumming...Because many species rely on low-frequency signals to communicate with conspecifics, they are likely to be especially vulnerable to signal masking and the concomitant biological effects associated with exposure to traffic noise. Here, we show that the spectral characteristics of traffic noise overlap extensively with footdrumming signals of the endangered Stephens’ kangaroo rat (Dipodomys stephensi; SKR)....
Estimating the audibility of industrial noise to denning polar bearsOil and gas activities on Alaska's North Slope overlap spatially with polar bear (Ursus maritimus) maternal denning habitat and temporally with the peri‐partum and emergence periods.... Our findings indicate that although polar bear snow dens effectively attenuate acoustic sound pressure levels, noise from some industrial support vehicles was likely to be detected farther from dens than previously documented. These results reinforce the importance of maintaining buffer zones....
Seasonal and diurnal patterns of behavior exhibited by Atlantic bottlenose dolphins (Tursiops truncatus) in the Mississippi SoundMany of the threats to bottlenose dolphins are anthropogenic factors including overfishing, high‐speed boats, chemical runoff, and noise pollution. Having a thorough understanding of the behavior and behavioral patterns of these animals can help with conservation plans to protect this species. This study examined the behavioral states and behavioral events of Atlantic bottlenose dolphins (Tursiops truncatus) in the Mississippi Sound....
