概括
气候变化影响整个生态系统的季节性时间. 这项研究发现,鸟类的表观不如植物和昆虫对温度敏感,增加了不匹配风险,特别是在高度地区.
科学领域:
- 生态生态学 生态生态学
- 气候变化生物学 气候变化生物学
- 现象学 现象学是指现象学.
背景情况:
- 气候变化正在改变生物事件的时间,导致现象学异步.
- 现象异步会导致人口减少,破坏生态系统功能.
- 需要广泛地比较不同热量级别的现象学暗示灵敏度.
研究的目的:
- 为了比较植物,昆虫和鸟类现象学对温度变化的敏感性.
- 为了确定最容易受到现象学不匹配的物种和地点.
- 评估使用植被绿化作为鸟类粮食资源定时的替代品的潜力.
主要方法:
- 综合了15年来关于森林绿化,白虫的出现以及北美东部的候鸟到来/繁殖的数据.
- 作为对累积增长度日 (GDD) 的响应量化的现象变化.
- 分析了现象学敏感度的度差异和影响鸟类到达转移的因素.
主要成果:
- 植物和昆虫现象学对GDD表现出类似的强烈敏感性;鸟类现象学对GDD的敏感性较低.
- 植被的绿化和鸟类的到来对高度的GDD更敏感,但鸟类的繁殖时间不那么敏感.
- 迁徙速度较慢的候鸟,较早到达的候鸟和北方的冬季息地表现出最大的到达转移.
结论:
- 植被变绿和昆虫出现的类似温度反应支持使用遥感来跟踪食物资源转移.
- 植物-昆虫-鸟类系统表现出一种更高的鸟类-昆虫现象不匹配的潜力,而不是昆虫-植物不匹配.
- 在研究的东部温带森林生态系统内,在更高的度处,现象脱风险较高.

Limits to Natural Selection
31.0K
Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

Frequency-dependent Selection
21.7K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Predator-Prey Interactions
16.1K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Symbiosis
27.2K
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Ecological Niches

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.
