摘要
火烧是扎龙保护区一个主要的生境干扰类型。为了了解散养丹顶鹤针对火烧而形成的行为时间分配差异,本文采用定点观察法、焦点取样法对火烧区不同情景下散养丹顶鹤孵化期行为差异进行了比较分析。结果显示:(1)扎龙保护区,散养丹顶鹤孵化期的行为以孵化、觅食、警戒为主(92.48%);(2)火烧区的出现,散养丹顶鹤的孵化、觅食、警戒行为时间分配会略高,而理羽和翻卵行为时间分配会略低;这种变化与火烧区的距离呈一定相关性。但卡方检验显示出,火烧区的存在和火烧区距离不影响散养丹顶鹤繁殖行为时间分配。进一步分析表明:轻度火烧下,散养丹顶鹤会微调繁殖行为时间分配,但不会出现显著影响。建议相关部门该时期可以采取轻度火烧的方式干扰丹顶鹤栖息环境。
Fire is one of the major disturbances to habitat in Zhalong National Nature Reserve ( ZNNR ).We used fixed-point observations and focused sampling to study the breeding behavior of free-ranging red-crowned cranes in response to reed fire.We quantified behaviors of semi-domestic cranes at various distances from fire areas.Incubation,foraging,and vigilance ( 92.48%) were the main behaviors.In burned areas,incubation,foraging,and vigilance accounted for slightly higher proportions of activity budgets,while preening and turning eggs slightly accounted for slightly less.None of the differences was significant.Further analysis showed that cranes did not significantly alter their behavior time budgets in response to lightly burned habitats.So,we recommend light burning of reed habitats during the breeding period of free-ranging red-crowned crane.
