对于许多物种来说，守护配偶会导致与正常行为的戏剧性偏离，这反映了对觅食和其他活动的注意受损。然而，以前很难在灵长类动物中记录这种离开。收集了雄性行为的两个方面的数据，预计这两个方面在配偶关系期间会受到限制，即个体旅行距离和觅食回合的持续时间，对于野生雄性巴布亚，在守护配偶的时期内和之外。在每一种情况下，伴侣关系的男性都会在伴侣关系之外与自己进行比较，在距离的情况下，他们也会与样本时间和地点相匹配的非伴侣男性进行比较。与不交往时相比，雄性交友时旅行的距离要短得多，结果是交友的雄性旅行的距离与雌性相似。雄性在交配时进食次数也明显缩短。交配的雄性经历的较短的旅行距离和觅食活动可能是对雄性觅食活动的重要限制，并可能导致在守护配偶期间能量摄入减少。季节性和非季节性繁殖模式将对守护配偶期间经历的能量储存和耗尽的波动幅度产生不同的后果，而非季节性繁殖物种守护配偶的成本将更难记录，因为它们必然较小且在时间上分散。然而，当考虑到整个寿命，非季节性繁殖者的配偶保护成本可能等于或超过季节性繁育者的成本。(C)1996年动物行为研究协会
For many species, mate guarding results in dramatic departures from normal behaviour that reflect compromised attention to feeding and other activities. Such departures have previously been difficult to document in primates, however. Data were gathered on two aspects of male behaviour that were predicted to be constrained during consortships, individual travel distance and duration of feeding bouts, for wild male baboons, Papio cynocephalus, in and out of mate-guarding episodes. In each case, consorting males were compared with themselves outside of consortships, and, in the case of distance travelled, they were compared also with non-consorting males matched for sample time and location. Males travelled significantly shorter distances while consorting than while not consorting, with the result that consorting males travelled distances similar to those travelled by females. Males also had significantly shorter feeding bouts while consorting. The shorter travel distances and feeding bouts experienced by consorting males may represent important constraints on male foraging activity, and probably result in decreased energy intake during mate guarding. Seasonal and non-seasonal breeding patterns will have different consequences for the magnitude of fluctuations in energy stores and depletions experienced during mate guarding, and costs of mate guarding in species that breed non-seasonally will be more difficult to document because they are necessarily smaller and temporally dispersed. When considered across the lifespan, however, mate guarding costs to non-seasonal breeders may equal or exceed costs to seasonal breeders. (C) 1996 The Association for the Study of Animal Behaviour
