动物可能会对邻居表现出攻击性。对一些鸟类来说，研究表明，雄性鸟类对来自其家园范围中心的邻居的叫声比来自边缘的叫声反应更强烈。这通常是通过假设一个家庭范围的中心比边缘对雄性更有价值来解释的。为了验证灵长类物种的这些想法，我们对野生雄性和雌性长尾叶猴（长臂猿）进行了大声呼叫的回放实验。这些动物可能会保护它们活动范围内的资源，或者保护它们的后代免受杀婴行为的侵害，雄性也可能会保护它们的雌性。在自然情况下，群体之间在一个家庭范围的中心遭遇闯入的邻居，往往伴随着杀婴的企图，而不是在边缘遭遇。从家区的中心播放的邻居的大声叫声比从边缘播放的叫声更能引起居住的雄性的强烈反应。然而，含食物树的雄性对边缘回放的反应与不含食物树的雄性没有区别。尽管男性似乎是在保护资源而不是配偶，但男性行为最好的解释可能是保护婴儿免受杀婴行为。女性的行为最好用资源防御来解释。
Animals may behave aggressively towards neighbours. For several bird species it has been shown that males react more vigorously towards calls of neighbours from the centre of their home range than from the edge. This is usually explained by assuming that the centre of a home range is of higher value to a male than the edge. To test these ideas for a primate species, we conducted experiments with playbacks of loud calls on wild male and female Thomas langurs (Presbytis thomasi). These animals may defend resources in their range or protect their offspring from infanticide and males may defend their females. In natural situations between-group encounters in the centre of a home range by the intruding neighbour are more often accompanied by infanticidal attempts than encounters at the edge. Loud calls of neighbours played back from the centre of the home range caused a more vigorous reaction from the resident male than calls from the edge. However, males in food-containing trees did not respond differently to edge playbacks from males in non-food-containing trees. Although males seem to defend resources and not mates, male behaviour may be best explained by defence of infants against infanticide. Female behaviour is best explained by resource defence.
