概括
商业参与者可以通过使用减缓等级来帮助生物多样性. 将MSA,LIFE和STAR等指标进行比较表明,使用多个指标并优先考虑避免损失对于实现无净损失 (NNL) 目标至关重要.
科学领域:
- 生态与保护科学 生态与保护科学
- 环境经济学环境经济学
- 企业的可持续性 企业的可持续发展
背景情况:
- 越来越多的企业和金融部门预计将为全球生物多样性保护工作做出贡献.
- 缓解等级 (避免,减少,补偿) 正在应用于企业价值链,以实现生物多样性的净损失 (NNL).
- 对不同指标的生物多样性丧失和获得等价性的量化对于NNL评估至关重要.
研究的目的:
- 评估和比较三个生物多样性指标:平均物种丰度 (MSA),土地覆盖面变化对未来灭绝的影响 (LIFE) 评分和物种威胁减缓和恢复 (STAR) 指标.
- 通过使用这些指标,评估空间规模限制对实现NNL的影响.
- 确定补偿企业生物多样性损失所需的最低恢复面积.
主要方法:
- 在全球NNL背景下对三个生物多样性指标 (MSA,LIFE,STAR) 的比较分析.
- 应用优化方法来确定最低修复区域.
- 研究空间规模对恢复有效性的限制.
主要成果:
- 在各个指标上,NNL的成就各不相同,并且在严格的空间限制下并不总是可能实现.
- 实现一个指标的NNL并不能保证其他指标的NNL.
- 该指标的性质 (例如,MSA与LIFE/STAR) 影响了所需的恢复总面积.
结论:
- 使用互补的生物多样性指标可以提高价值链级别NNL评估的可靠性.
- 优先考虑避免和最小化生物多样性损失至关重要,因为补偿可能受到空间限制的限制.

What is Biodiversity?
32.3K
Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.

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...

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
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.

Conservation of Small Populations
16.6K
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...

What is Conservation Biology?
23.9K
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.
