概括
城市环境扰乱了鸟类的日常活动节奏,导致一些物种更早开始活动,所有物种的夜间活动增加. 与森林鸟类相比,城市鸟类表现出不太一致的行为和较低的人口同步性.
科学领域:
- 生态生态学 生态生态学
- 动物行为 动物行为
- 城市生态城市生态学
背景情况:
- 行为活动的特定模式对地球上的生命至关重要,但城市环境可以破坏这些节奏.
- 之前关于城市对动物活动模式的影响的研究范围有限,往往关注单一物种和季节.
- 人们对城市和非城市人口中个人之间活动模式的变化知之甚少.
研究的目的:
- 研究城市化对六种鸟鸟类日常活动模式的影响.
- 研究城市对活动开始,偏移,持续时间和水平 (白天和夜间) 的影响.
- 量化城市和森林人口之间的活动特征在个体之间和个体内变化的差异.
主要方法:
- 使用自动无线电遥测来记录日常活动模式.
- 研究了六种流物种 (黑鸟,红,大,蓝,,).
- 在繁殖前和繁殖后的季节,收集了两个城市和两个森林种群的数据.
主要成果:
- 城市黑鸟和红比森林黑鸟更早地开始日常活动;这种影响是特定于物种的.
- 所有城市鸟类种群都表现出更高的夜间活动水平,这表明日常能量需求增加.
- 城市鸟类表现出更可变的活动时间 (开始和结束),无论是在个体之间还是在个体内,表明同步性和一致性减少.
结论:
- 城市化改变了鸟类的日常活动节奏,导致休息,一致性和同步性减少.
- 城市化的影响取决于物种和季节,警告不要一般化.
- 需要进一步的研究,以了解驱动这些观察到的鸟类行为差异的机制.

00:53Migration
7.8K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

02:45Biological Clocks and Seasonal Responses
34.5K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

02:19Circadian Rhythms and Gene Regulation
4.0K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

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.

00:51Energy Budgets
9.1K
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...

01:46Types of Selection
39.8K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...
