在加拿大不列颠哥伦比亚省枫树岭的不列颠哥伦比亚省大学研究森林中进行了围栏生物测定，研究了捕食者气味（粪便和尿液）在抑制黑尾鹿摄食损害中的有效性。共有8个生物测定试验测试了这些气味对鹿食用沙巴叶和针叶树幼苗的影响。美洲狮、郊狼和狼的粪便以及郊狼、狼、狐狸、金刚狼、猞猁和山猫的尿液对鹿的摄食损害提供了最有效的抑制。氨和人尿的新气味并没有减少进食。捕食者粪便气味制剂在直接叶面施用、粘合剂施用和塑料小瓶中均有效抑制鹿进食。在所有测试的尿液中，土狼提供了最一致的抑制鹿浏览沙拉。鹿消耗显着更多的未经处理的道格拉斯冷杉和西部红雪松幼苗比那些受保护的土狼尿气味。抑制鹿摄食的捕食者气味的活性驱避组分可能适合于封装在控释装置中，可以为森林和农作物提供长期保护。
The effectiveness of predator odors (fecal and urine) in suppressing feeding damage by black-tailed deer was investigated in pen bioassays at the University of British Columbia Research Forest, Maple Ridge, British Columbia, Canada. A total of eight bioassay trials tested the effects of these odors on deer consumption of salal leaves and coniferous seedlings. Cougar, coyote,and wolf feces as well as coyote, wolf, fox, wolverine, lynx, and bobcat urines provided the most effective suppression of deer feeding damage. Novel odors of ammonia and human urine did not reduce feeding. Predator fecal odor formulations in direct foliar application, adhesive application, and in plastic vials were all effective in suppressing deer feeding. Of all urines tested, coyote provided the most consistent suppression of deer browsing on salal. Deer consumed significantly more untreated Douglas fir and western red cedar seedlings than those protected by coyote urine odor. The active repellent components of predator odors which suppress deer feeding may be suitable for encapsulation in controlled-release devices which could provide long-term protection for forest and agricultural crops.
