Conservation of Declining Populations02:07

Conservation of Declining Populations

12.5K
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.

What is Climate?01:16

What is Climate?

20.4K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Threats to Biodiversity01:50

Threats to Biodiversity

26.5K
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...

Global Climate Change

28.7K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Generalization, Discrimination, and Extinction01:24

Generalization, Discrimination, and Extinction

1.3K
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Habitat Fragmentation02:31

Habitat Fragmentation

20.9K
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.

此摘要是机器生成的。

种类-区域关系 (SARs) 可能会高估灭绝风险. 这项研究认为,在评估息地和气候变化造成的生物多样性丧失方面,特有病区关系 (EAR) 更适合,这挑战了以前的说法.

  • 生物多样性科学 生物多样性科学
  • 保护生物学 保护生物学

背景情况:

  • 种类-区域关系 (SARs) 常用于估计由于息地丧失或气候变化的灭绝风险.
  • 他和Hubbell (2011) 建议使用特有病区关系 (EAR) 而不是SAR,这表明基于SAR的估计过高.

研究的目的:

  • 批判性地评估He and Hubbell (2011) 关于灭绝风险评估的SAR和EAR所提出的方法和结论.
  • 为了证明SAR对灭绝风险的估计并不一定是有偏见的,并且He和Hubbell使用的经验数据可能不适合他们的分析.

主要方法:

  • 在物种-区域关系 (SAR) 分析中使用的统计方法的重新评估.
  • 对有关物种分布和息地面积的经验数据的分析.
  • 从SARs获得的灭绝风险估计的比较与特有病区关系 (EARs).

主要成果:

  • 关于灭绝风险的SAR估计可能是有偏见的,并不是本质上太高.
  • 希和哈贝尔使用的经验数据不适合进行可靠的灭绝风险计算.
  • 以前的论点表明气候变化导致的灭绝风险较低是有缺陷的,因为物种的反应表明未来存在重大风险.

结论:

  • 与He和Hubbell的说法相反,SAR仍然是评估灭绝风险的有效工具.
  • 物种已经在对气候变化的反应中表现出与未来大量灭绝风险相一致的反应.
  • 准确评估生物多样性丧失需要仔细考虑方法和适当的经验数据.
