基于种群生存力分析的陕西铜川朱鹮再引入种群的可持续性及保护对策
野生动物学报种群生存力分析（population viability analysis，PVA）虽然已经在濒危物种的保护管理中得到广泛应用，但目前面临的严峻挑战是如何采用PVA分析影响濒危物种种群长期维持的内外因子。经过数十年的保护，朱鹮（Nipponia nippon）野生种群的数量已经从7只增长到约4 400只，若干再引入计划也分别在中国、日本和韩国相继实施。过去的研究表明，种群统计随机性、灾害和种群性比等因素是影响朱鹮野生种群稳定增长的主要因素，然而，对影响朱鹮再引入种群长期稳定维持的因素却知之甚少 ...

野生动物学报, 2009 对扎龙湿地的水鸟群落进行资源调查,共记录水禽52种,隶属于5目11科。其中古北界种类42种（占82%）,广布种类10种（占18%）,东洋界种类无记录。对结果进行分析发现:扎龙自然保护区水鸟群落种类和数量随着迁徙活动呈现了明显的季节性变化。春季水鸟迁徙时间集中,种群数量变化剧烈,有高峰期;秋季水鸟迁徙时间分散,种群数量变化缓和,无明显的高峰期。

Study on dinoflagellate cysts of Holocene and their environmental significance in Bohai Sea [PDF]
, 2016 甲藻是一种非常古老的真核生物，许多甲藻能产生休眠孢囊。沉积物中的甲藻休眠孢囊对反映海水温度、盐度、营养盐及海平面变化等环境因子具有非常重要的意义，其还可以揭示赤潮发生的潜能。渤海是我国半封闭的内海，受地形地貌、气候、海洋水文及人类活动影响较为显著。本文对渤海表层及柱状沉积物中的甲藻孢囊进行研究，表层样结合现代数理统计软件细致地分析了甲藻孢囊的种类组成、分布特征及与环境因子的关系。柱状样结合地层年代通过优势种在各层位的含量变化，探讨了渤海近8000aBP年以来海水的温度、盐度 ...
