概括

新疆的野生动物通道很少,经常被重新使用. 类动物和鸟类利用它们,在夏季/秋季和夜间使用达到峰值. 优化通道设计和管理对于生物多样性保护至关重要.

科学领域:

生态生态学生态生态学
保护生物学保护生物学
野生动物管理野生动物管理

背景情况:

线性基础设施的扩张对生物多样性构成重大威胁.
为了有效的保护,需要对空间变异的区域研究和多物种研究.
野生动物通道对于缓解息地碎片化至关重要.

研究的目的:

为了调查和监测新疆八个自然保护区的野生动物通道.
评估通道建设,利用模式和影响因素.
为野生动物通道管理提供优化建议.

主要方法:

实地调查和监测8个自然保护区的野生动物通道.
记录利用通道的野生动物物种 (32种物种被观察到:13种鸟类,19种哺乳动物).
分析影响通道利用的因素,包括季节性,日间变化,人类活动和基础设施密度.

主要成果:

专门的野生动物通道很少,许多保护区依赖于重新设计的水槽和桥梁.
类动物 (,,野驴,驼) 显示出高通道利用率.
通道使用因季节性 (冬季最低,夏季/秋季高峰) 和日间 (夜间最高) 变化而有所不同.
鸟类通过利用在迁徙季节 (四月) 达到峰值.
人类活动的强度和线性基础设施密度显著限制了通道利用率.
通道类型,尺寸和接近水的位置是关键因素.

结论:

强烈建议加强专门的野生动物通道的建设,特别是在较小的保护区.
通道的设计和管理必须考虑季节和日间变化,尽量减少野生动物运动高峰时间 (夜晚,黎明,黄昏) 的人类干扰.
优化通道布局,增加通道密度和改善生态功能是促进野生动物移动和保护新疆生物多样性的关键策略.

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Habitat Fragmentation

Habitat Fragmentation

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

What is Conservation Biology?

What is Conservation Biology?

Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...
