野生动物学报, 2017 2010年11月～2011年2月,通过对商丘及郑州地区道路两侧喜鹊(Pica picas)营巢情况的调查,从巢位选择、营巢树木特征、周边环境因素等方面探究了不同因子对喜鹊巢址选择的影响。共观测鸟巢39个,可测变量13个,营巢树种均为枫杨(Pterocarya stenoptera)。χ2检验结果表明,喜鹊选择营巢的行道树高度一般大于16 m、树径一般大于0.2 m; 营巢位置多距树顶2～5 m且多选择分枝数为3的树木营巢。Hotelling T2检验表明 ...

野生动物学报, 2007 2002～2004年3～8月,在扎龙国家级自然保护区,通过定点观察法、样方法、因子测定法等对丹顶鹤育雏期的生境选择进行了研究,旨在为丹顶鹤种群的有效保护提供基础资料。结果表明:扎龙保护区,育雏期不同阶段丹顶鹤的育雏生境选择不同,育雏前期,丹顶鹤选择芦苇沼泽,仅局限于以巢址为中心的小范围内活动;育雏后期,丹顶鹤的育雏活动范围开始向外扩展甚至与巢址生境不同,偏爱于开阔度较大且能提供水和隐蔽的苔草沼泽。

野生动物学报, 2011 采用样线法以巢址为指标在红花尔基樟子松林国家级自然保护区对松鼠的生境保护选择进行了定量研究。使用样线法进行调查,共获取147个巢样方和160个对照样方,对每个样方分别测定了8个环境参数。主成分分析结果表明,影响松鼠巢址选择的诸因素重要性依次为:林型、生境的郁闭程度、生境所处坡向坡位。松鼠显著倾向于在利用苔草樟子松林,随机利用其他类型樟子松林,而对杨桦林等则倾向回避。松鼠巢树周围的树木密度和多样性显著高于对照样方。巢址生境多位于南向的中、下坡位。

Conservation Biology, Volume 37, Issue 3, June 2023., 2023 Abstract Many species are restricted to a marginal or suboptimal fraction of their historical range due to anthropogenic impacts, making it hard to interpret their ecological preferences from modern‐day data alone. However, inferring past ecological states is limited by the availability of robust data and biases in historical archives, posing a ...

Responses of New Zealand forest birds to management of introduced mammals
Conservation Biology, Volume 35, Issue 1, Page 35-49, February 2021., 2021 Abstract Over the past 1000 years New Zealand has lost 40–50% of its bird species, and over half of these extinctions are attributable to predation by introduced mammals. Populations of many extant forest bird species continue to be depredated by mammals, especially rats, possums, and mustelids.

Estimation of spatiotemporal trends in bat abundance from mortality data collected at wind turbines
Conservation Biology, Volume 35, Issue 1, Page 227-238, February 2021., 2021 Abstract Renewable energy sources, such as wind energy, are essential tools for reducing the causes of climate change, but wind turbines can pose a collision risk for bats. To date, the population‐level effects of wind‐related mortality have been estimated for only 1 bat species. To estimate temporal trends in bat abundance, we considered wind turbines

World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

Politics &Policy, Volume 54, Issue 4, August 2026.ABSTRACT This study examines how institutional arrangements associated with economic security reshape semiconductor production in East Asia through the case of TSMC's investment in Kumamoto, Japan. It argues that economic security operates not primarily through direct administrative control, but by redefining acceptable investment risks, narrowing ...

Review of Policy Research, Volume 43, Issue 3, May 2026.ABSTRACT Zoning is one of the most widely used land use regulations in the U.S. An increasing number of local governments have adopted zoning ordinances to regulate renewable energy projects. However, there has been very limited research on the impact of this local regulatory tool.
