昆虫骚扰会减少驯鹿的进食和躺卧时间以及增加运动量，从而显着影响驯鹿的行为。当没有昆虫时，油田干扰对行为的影响最为明显，这表明干扰和昆虫对行为没有显着的累加效应。当没有昆虫时，有交通的高架管道和道路 600 m 范围内的驯鹿以及无交通的管道和道路 300 m 范围内的驯鹿的活动预算与未受干扰的驯鹿有显着不同；在有交通的地方，干扰效应明显更大。躺卧和奔跑的时间以及运动速率是油田干扰的最佳指标，而进食的时间不受影响。与其他群体类型相比，以母牛为主的群体和超过 10 只动物的群体对干扰水平的反应较低，但所有群体类型对高水平干扰的反应相似。建议将高架管道与交通繁忙的道路分开...
Insect harassment significantly affected caribou behavior by decreasing time spent feeding and lying and by increasing locomotion. Effects of oilfield disturbance on behavior were most pronounced when insects were absent, suggesting that disturbance and insects did not have a substantial additive effect on behavior. When insects were absent, caribou within 600 m of an elevated pipeline and road with traffic, and within 300 m of a pipeline and road without traffic, had significantly different activity budgets than undisturbed caribou; disturbance effects were significantly greater in the site with traffic. Time spent lying and running and movement rates were the best indicators of oilfield disturbance, whereas time spent feeding was not affected. Cow–calf-dominated groups and groups larger than 10 animals reacted to lower levels of disturbance than other group types, but all group types reacted similarly to high levels of disturbance. Separation of elevated pipelines from heavily traveled roads is recommen...
