为探讨高原鼠兔家群空间领域的季节特征,分别于2005年和2006年的5 ～8月,在青海省玛沁县,采用标志重捕法和最小多边形面积法对其家群巢区和核域进行了研究。结果表明,不同季节,高原鼠兔巢区和核域面积存在显著差异。5、6月份,成体巢区面积显著大于幼体,但二者核域面积却无显著差异; 7月份,成体与第1胎幼体巢区及核域面积均显著大于第2胎。5、6月份雄性成体巢区显著大于7、8月份, 6、7月份雌性成体巢区显著大于5月和8月份。巢区及核域面积均与家群个体数呈极显著性正相关关系,说明季节和家群结构均可对高原鼠兔空间领域产生重要作用。

采用标志重捕法测定高原鼠兔家群年龄结构和性比,探讨其家群结构的季节变异及原因。结果显示,繁殖早期,家群由越冬成体和第1胎幼体构成;繁殖后期,家群主要由第1胎幼体构成。高原鼠兔家群年龄结构依季节存在显著的差异。5月,成体和雌性第1胎幼体个体数显著多于其他月份;5月和6月雄性第1胎幼体个体数显著多于7月和8月;6月第2胎幼体个体数显著多于7月和8月;7月雄性第2胎幼体个体数显著多于8月。7月和8月,第1胎幼体个体数显著多于第2胎幼体。高原鼠兔家群内5月成体性比显著高于7月和8月。结果表明,高原鼠兔在冬季漫长、食物匮乏以及繁殖季节极短等条件下,调整家群结构,提高繁殖成功率,使其种群在严酷的高寒环境中得以延续。

随着人们对资源的加速利用,生境丧失和破碎化导致物种濒危问题日益严重.以岛屿生物地理学为理论起源的种群生存力分析(PVA),通过分析和模拟种群动态过程并建立灭绝概率与种群数量之间的关系,为濒危物种保护提供了重要的理论依据和研究途径.在过去的几十年中,种群生存力分析已成为保护生物学中一项重要的研究内容.目前种群生存力分析发展稳定,但对其实际预测能力和准确性尚存质疑,应用方面也有待进一步发展.种群生存力分析的进一步完善还需要在理论和方法上的创新,特别是籍于景观生态学和可持续性科学的理念,将空间分析手段、经济社会因素纳入到物种和种群的预测和管理上,从而使其具有更完整的理论基础和更高的实用价值.为此,本文对种群生存力分析的历史、基本概念、研究方法、模型应用和准确性进行了综述,并提出了有关的研究展望.
