The objective of the study was to determine whether surgical sterilization of both males and females in wolf pairs alters basic wolf social and territorial behaviors. Wolves were located from the air by snow-tracking methods and were tranquilizer-darted from a helicopter. Surgeries were performed either in a tent at the capture site or in a heated building in a nearby village. Six vasectomies and seven uterine horn ligations were performed in January and February of 1996 and 1997. Two females died: one likely related to the capture procedure, the other of a peritonitis unrelated to the surgery. One wolf had a litter. None of the wolves have shown changes in behavioral patterns. Surgical sterilization can be effective, but other, less invasive, fertility control techniques should be investigated.
该研究的目的是确定对狼夫妇中的雄性和雌性进行手术绝育是否会改变狼的基本社会和领地行为。通过雪地追踪方法从空中定位狼，并从直升机上用麻醉镖使其镇静。手术在捕获地点的帐篷中或附近村庄的加热建筑中进行。在1996年和1997年的1月和2月进行了6例输精管切除术和7例子宫角结扎术。两只雌性死亡：一只可能与捕获过程有关，另一只死于与手术无关的腹膜炎。一只狼产仔。没有一只狼的行为模式发生变化。手术绝育可能有效，但应该研究其他侵入性较小的生育控制技术。
