Scientists played human voices near Alaska salmon streams and found that bears and eagles fled, disrupting how salmon nutrients move into forests
New findings from Canadian researchers reveal that human sounds near Alaska's salmon streams significantly disturb wildlife, leading to grizzly bears avoiding feeding areas. This interference disrupts the natural nutrient transfer to surrounding forests, emphasizing the detrimental effects of human activity on essential ecosystem dynamics. Scientists propose enhanced land management practices to safeguard these critical ecological processes.
