生活史是鸟类生态学研究的重要内容之一,分析生活史的影响因子对于研究鸟类的生态适应具有重要意义。2007年3 ~ 9月,在广东省肇庆市江溪村对黄腹山鹪莺(Prinia flaviventris)和纯色山鹪莺(P. inornata)的繁殖参数进行了比较研究。结果表明:1)除筑巢集中期、窝卵数、巢捕食率和割草毁巢率外,两种山鹪莺各繁殖参数均存在显著性差异;2)黄腹山鹪莺的窝卵数相对较小,但卵重较大,而纯色山鹪莺则相反;3)与体重相似的9种雀形目鸟类相比,两种山鹪莺具有相对较高的年生产力;4)两种山鹪莺在部分繁殖参数上出现了分化,这可能是它们对不同巢捕食风险的响应,黄腹山鹪莺的巢捕食率相对较高,采取低窝卵数和高的卵重,而纯色山鹪莺则为高的窝卵数和低的卵重。 |

Life history is an important topic in avian ecology, and the determinants of life history traits are important for understanding bird ecological adaption. Comparisons of breeding parameters of Yellow-bellied Prinia Prinia flaviventris and Plain Prinia P. inornata were performed at Jiangxi Village, Zhaoqing, Guangdong, from March to September in 2007. Our results showed that: 1) there were no significant differences in various breeding parameters between two Prinia, except for nest-building period, clutch size, nest predation rate and nest destruction rate (Table 1); 2) Yellow-bellied Prinia had lower clutch size but larger egg size, compared with the Plain Prinia; 3) these two Prinia species had relatively higher annual productivity compared with nine passerine birds of similar body mass (Fig. 2); 4) there was obvious differentiation between two Prinia species in most of breeding parameters, possibly caused by different nest predation risks. Our findings suggested that Yellow-bellied Prinia responded to relatively high nest predation with lower clutch size but larger egg size, while Plain Prinia had higher clutch size but smaller egg size. |
