| impacts of chronic anthropogenic noise from energy-sector activity on abundance of songbirds in the boreal forest. | the effects of human activities in forests are often examined in the context of habitat conversion. changes in habitat structure and composition are also associated with increases in the activity of people with vehicles and equipment, which results in increases in anthropogenic noise. anthropogenic noise may reduce habitat quality for many species, particularly those that rely on acoustic signals for communication. we compared the density and occupancy rate of forest passerines close to versus f ... | 2008 | 18616740 |
