没想到,一天敢睡20小时才配当狮子王……
今天,猫盟翻译组就带大家一起跟着狮子去巡大草原!
文章不能白看哦,找找这些问题的答案吧!
1. 狮子最常见的领地行为是什么?
2. 亚成体的领地行为和成体的有什么区别呢?
3. 母狮子会叫吗?
压轴题是这个哦!
一头雌性狮子可以和几头雄性个体繁殖后代呢?

由此可知,雄狮对领土的维护和守卫可以决定其幼崽能否成长为能为种群效力的一员。
领地行为的直接好处包括守卫巢区、交配和食物资源;最终优势是增加个体的适合度。
而这些多是通过雄性联盟完成的,使得雄性联盟对于狮子的意义不同于其他猫科(Bertram1975a, Caro 1994)。
但雄狮三岁就会被狮群放逐离群,经过一段流浪生涯后,进入雄狮联盟,四岁后便有机会掌控一个狮群,直到被其他雄性取代而再次被放逐。
这说明雄狮必须在它的“任期”中进行最大限度的繁殖,雄狮一生中经常只能成功繁殖一窝幼崽。
就此来讲,研究雄狮投入在领地巡视上的时间、领地性信号的形成与种类可以让我们更深入了解雄狮的社会组成和生存能力。
在持续监测期间,吼叫的总持续时间也被记录下来,并以频率的平均值进行计算。
标记发生在清晨和傍晚;
在交配的过程中,雄性完全不发声。
和以前所报道的只在狮群内交配,最近的研究显示,狮子也会在狮群外交配。
吼叫和标记行为既被用来圈定领地,又被当作沟通工具,其作用也有待探索。

相比其他论文,这篇可能没有那么重的“科研味”,不但篇幅较短,也没有晦涩难懂的数据分析。(很碎,但细节又很好玩……读起来就像在读那些我追的摇滚老男人的……自传)
