【摘要】 比较来自低海拔和青藏高原高海拔系统发育成对的雉类和鹑类的生殖对策,得出如下结论。高海拔种类(亚种)生殖对策有明显的多样性,主要有4种模式:(1)产大窝大卵;(2) 产大窝小卵;(3)产小窝和小卵和(4)产小窝大卵。除第四种为k-选择外,其它高海拔的鸡类既表现为k-选择,又表现为r-选择。它们都有各自行为和种群统计学对策,尤其雄性行为,以提高雏鸟的存活率。它们的生殖对策由几种权衡决定,窝卵数与幼鸟存活间的权衡; 一次生殖与多次生殖的权衡。青藏高原的隆升和环境强烈影响鹑鸡类的生殖对策。更多还原

【Abstract】 In this paper, we have examined the pattern of covariation in Galliformes breeding strategies along an altitudinal gradient by comparing their life history traits including most components of parental care, differing among phylogenetically paired species of Phasianini and Perdicini between low-and high-elevation sites. We obtain the following conclusion. The reproductive strategies of Galliformes in alpine area obviously exhibit diversity. There were mainly four patterns: (1) large clutch size of larger egg; (2) large clutch size of smaller egg; (3) small clutch size smaller egg; and (4) small clutch size of larger egg. Except for the fourth pattern being k-select, the reproductive strategies were both k-select and r-select. They had respective behaviors and population statistic strategies, especially male behaviors, to increase fledglings’ survival rate. Their reproductive strategies were depended on some kinds of trade-offs, between clutch size and fledglings survive, between once breeding and times breeding. The uplift of Qinghai-Tibet Plateau and environment intensely affected the reproductive strategies of Galliformes in highland.更多还原
