虎皮鸚鵡社會(huì)等級(jí)對(duì)擇偶復(fù)制和選型配對(duì)的影響摘要：

本論文采用了野外調(diào)查和實(shí)驗(yàn)研究相結(jié)合的方法，通過(guò)對(duì)虎皮鸚鵡不同社會(huì)等級(jí)的個(gè)體進(jìn)行觀察和實(shí)驗(yàn)操作，在擇偶復(fù)制和選型配對(duì)方面進(jìn)行了研究。結(jié)果表明，虎皮鸚鵡個(gè)體的社會(huì)等級(jí)對(duì)其擇偶復(fù)制和選型配對(duì)具有很大的影響。高等級(jí)的虎皮鸚鵡在選配方面更加注重品質(zhì)相近、適應(yīng)環(huán)境的個(gè)體，而低等級(jí)的虎皮鸚鵡則更容易選擇長(zhǎng)相較好、行為鮮明的個(gè)體。同時(shí)，在擇偶復(fù)制方面，高等級(jí)的虎皮鸚鵡更容易被其他配偶模仿，而低等級(jí)的虎皮鸚鵡則更容易模仿配偶。本研究提出了虎皮鸚鵡個(gè)體選擇伴侶和形成繁殖關(guān)系的機(jī)制，以及其與社會(huì)等級(jí)的關(guān)聯(lián)，為進(jìn)一步探討鳥(niǎo)類(lèi)擇偶和社會(huì)行為提供了參考。
