- 环境科学 环境科学
- 野生动物管理 野生动物管理
背景情况:
- 工业发展,特别是在加拿大的北极森林,导致对生物多样性的累积环境影响.
- 工业足迹对野生动物种群的影响取决于规模,在生态理解和管理策略方面造成不确定性.
研究的目的:
- 估计能源部门发展对16种迁徙歌鸟物种分布的累积影响.
- 评估加拿大阿尔伯塔省多个空间尺度对歌鸟对能源发展的反应中尺度域的证据.
主要方法:

- 贝叶斯拉索被用来直接比较五个空间尺度的参数估计.
- 在物种之间测试了分组参数估计的差异,以确定尺度域.
主要成果:
- 在所有研究的歌鸟物种中观察到一致的依赖规模的模式.
- 歌鸟的反应各不相同,在中间尺度的影响很小,但在最大尺度的影响更强大,主要是积极的.
- 发现了对能源部门发展的歌鸟反应中规模域的强有力的证据,这些证据是由跨规模的分组参数估计的差异表明的.
结论:

22.3K
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...

00:51Energy Budgets
9.2K
Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

02:04Conservation of Small Populations
13.1K
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...

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.

02:26Ecological Disturbance
17.1K
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.
