异地半圈养藏羚卧息行为适应性的初步研究

藏羚Pantholops hodgsoni是青藏高原特有物种。为了探讨藏羚羊对异地环境的行为学适应,对异地圈养藏羚羊的卧息行为进行了不同性别、不同季节间的比较研究。采用全事件记录法和焦点动物取样法,记录和统计了异地圈养藏羚羊冷季和暖季的卧息行为。研究结果表明,在暖季,雌性和雄性藏羚羊在卧息时间及卧息时间占全天活动时间的比例(卧息比例)上没有差异(卧息时间:Z=-1.126,P0.05;卧息比例:Z=-1.357,P0.05);在冷季,雌性和雄性藏羚羊在卧息时间及卧息比例上也没有差异(卧息时间:Z=-1.14,P0.05;卧息比例:Z=-0.307,P0.05)。雄、雌性藏羚羊的卧息时间及卧息比例没有季节差异(雄性卧息时间:Z=-1.465,P0.05;雄性卧息比例:Z=-1.631,P0.05;雌性卧息时间:Z=-1.742,P0.05;雌性卧息比例:Z=-1.852,P0.05)。季节和性别对藏羚羊卧息行为的影响没有交互作用(F=0.057,P0.05)。总之,藏羚羊卧息行为之间既没有性别差异也没有季节差异,与可可西里地区藏羚羊的卧息行为相比,异地圈养藏羚羊的卧息行为已经调整其行为学适应对策。

Adaptation of Resting Behavior in Ex Situ Conservation of Tibetan Antelope

Tibetan antelope Pantholops hodgsoni is endemic to the Tibetan Plateau.Ex situ conservation may represent a potential settlement to accommodate Tibetan antelope,however impacts of their behavior might be generated during the process.To explore whether these antelope is capable for accommodating to a new environment,we examined the resting behavior of captive antelope taking both sex and season into consideration.By means of instantaneous scan sampling,focal animal sampling and all-occurrence recording methods,we recorded and analyzed resting rate and resting time of captive male and female Tibetan antelope during the cold and warm seasons.No differences in resting behavior were found between sexes,as males and females rest for a similar length of time and at a similar rate throughout the observational period.Moreover,no differences in resting behavior were found between seasons throughout the observational period.No interaction was found between variables of seasons and sexes on the resting behavior of antelope.In summary,no differences were found in resting behavior of Tibetan antelope between variables of sexes or seasons.After compared with the resting behavior of the Kekexili Tibetan antelope,these results indicate that captive antelope may adapt to a new environment.
