A skeletochronological study was conducted for the age, longevity and growth of a Rana nigromaculata population in northeastern Sichuan, China. Of 139 specimens, 119(68 males and 51 females) exhibited distinct arrested growth lines in phalanges. Age at first reproduction was found to be two years of age for males and three for females. Maximum longevity was estimated to be at least six years in males and seven years in females. Average age did not differ between males and females. Breeding females were significantly older than breeding males. Females were larger in body size and heavier in body mass than males. Age was not correlated with body size and body mass in males, but a significant correlation was found among age, body size and body mass in females. The growth curve appeared significantly different between the sexes, with a higher growth rate throughout life and a larger asymptotic size in females. Moreover, analysis of the growth model indicated that the population studied was relatively stable.

Testes size in most animals commonly shows directional asymmetry. In birds, the left testis mass is usually larger than the right one, but the reports on the testes asymmetry in anurans are very few. Moller （1994） hypothesized that the right testis serves a compensatory role and increases in size when the left one is defective, and further suggested that testes asymmetry may be a reliable indicator of individual body condition. In this paper, we tested the compensation hypothesis in the Guenther＇s frog, Hylarana guentheri. From 60 sampled males, we found that there was a significant directional asymmetry in testes mass, with the left testis size being significantly correlated with relative testes asymmetry, providing evidence that the right testis had a compensatory function. However, testes mass and asymmetry were not correlated with body condition. Hence, we found no evidence that testes asymmetry in the Guenther＇s frog reflected male condition, and male age was also not related to testes mass or asymmetry.

岩羊为国家Ⅱ级保护动物。目前,由于人类活动范围日益扩大,其栖息地遭到了不同程度的破坏,岩羊种群数量和分布范围呈明显下降趋势。为了及时制定科学的保护策略必须了解它们的种群遗传结构。本文以粪便为研究材料,对来自金沙江河谷地区林线以上岩羊和林线以下矮个子岩羊共4个地理种群的169份有效样品进行线粒体CR全序列分析,共检测出210个变异位点,定义了4种单倍型,单倍型多样性为0.68,核苷酸多样性为0.0242,显示种群整体遗传多样性水平较低。基于最大简约法构建的系统发育树中,金沙江河谷地区的4个地理种群被划分到四川种群的2个亚分支中,但云南曲宗贡的部分岩羊和四川竹巴笼的矮个子岩羊单倍型存在共享现象。根据分子钟计算,林线上下岩羊分化时间在39～32万年前,在中更新世早中期（105～36万年前）气候影响下,导致岩羊在金沙江河谷高低海拔之间相互迁移。对于岩羊在历史上所表现出的潜在迁徙能力,我们建议将白马雪山自然保护区到竹巴笼自然保护区之间的金沙江河谷地区作为岩羊和矮个子岩羊的栖息地整体保护。

2004年3～10月对四川南充地区家燕、金腰燕的繁殖生态进行了观察,比较了其繁殖生态习性及雏鸟的生长特性,进行了家燕、金腰燕之间的易卵易雏实验.结果表明,家燕于2月中旬迁入南充,9月中旬开始迁离;金腰燕迁来较家燕晚,2月底～3月初迁入,9月中旬迁离.家燕于4月初产卵;金腰燕在4月上旬产卵.金腰燕卵的各项量衡度均较家燕的大,出壳时金腰燕雏鸟体重也比家燕雏鸟稍重.金腰燕雏鸟的体长、翅长、尾长、外部器官及体重的增长较家燕的快.而易卵、易雏的金腰燕雏鸟增长曲线则在金腰燕和家燕的雏鸟之间.易卵易雏的实验表明,在孵卵和育雏过程中,金腰燕与家燕之间彼此互换卵可以接受,易换雏鸟也可以接受.

为了解鸟击规律,作者收集了重庆江北机场2009—2013年的鸟击事件信息并对鸟击残骸进行送检,共收集鸟击事件信息189起,其中白天77起,占40.74%,夜间112起,占59.26%。鸟击数据显示:春、夏、秋季是鸟击高发季节;8月和11月为白天鸟击高发月份;夜间鸟击高发在春季(4、5月)和秋季(8、9、10月);鸟击多发种类有小云雀、家鸽、家燕、金腰燕、白鹡鸰、池鹭、大杜鹃及蝙蝠等。结合江北机场鸟类群落调查数据分析发现:在飞行区集群活动的鸟种容易成为鸟击的高危物种,鸟击发生频率与鸟类生活习性关系密切;迁徙鸟类是江北机场鸟击的最大威胁。本文根据分析结果提出了一些相应的预防措施。
