概括
基于物种本土性的保护决策可能会忽视社会价值观,并产生公平后果. 种族,而不是生态知识,显著地影响了对本土与非本土物种减少的悲伤.
科学领域:
- 保护生物学 保护生物学
- 人类生态人类生态学
- 环境社会学 环境社会学
背景情况:
- 像本土性这样的中央保护生物学概念受到社会和生态因素的影响.
- 在保护决策中使用本土性的社会影响尚未得到充分理解.
- 原生性可能会掩盖社会价值观,导致原生物种的优先考虑,尽管非原生物种的数量下降.
研究的目的:
- 为了评估公众对本地和非本地鸟类的看法,大温哥华地区的鸟类数量下降.
- 测量与鸟类数量减少有关的生态悲伤和文化生态系统服务的损失.
- 检查自然体验和社会人口统计学,特别是种族,如何影响这些感知.
主要方法:
- 在温哥华大都市调查了600人关于鸟类数量减少的问题.
- 对本地和非本地鸟类的生态悲伤和文化生态系统服务损失的测量.
- 采用了两种处理的实验设计,告诉一半关于物种原生性的信息.
- 分析基于熟悉,经验,社会人口统计和种族的感知.
主要成果:
- 对损失的看法因鸟类的熟悉程度,经验和原住民地位而有所不同.
- 种族是最强的调节者:只有白人对本地物种的减少表示更大的悲伤.
- 生态知识,城市化或自然体验并没有缓解本地人对悲伤的影响.
结论:
- 仅仅依靠原住民身份进行保护可能会导致意想不到的社会人口统计和公平问题.
- 种族显著影响对物种减少的情感反应,突出了对保护的公平关切.
- 生态悲伤和文化生态系统服务措施有效地揭示了复杂的人与自然的关系,包括与非本土物种的复杂关系.

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

32.2K
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.

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

01:21The Nativist Approach
348
The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...

26.4K
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...

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...
