- 类学 类学 类学 类学
背景情况:
- 由于气候变化,物种现象学正在迅速变化,两动物表现出显著的反应.
- 两动物活动高度依赖温度和降雨量,使它们成为气候变化的敏感指标.
- 现象变化可能会对两动物的健康产生负面影响,需要保护策略.
研究的目的:
- 确定影响普通脚 (Pelobates fuscus) 生殖迁徙的因素.
- 在8年的时间内评估Pelobates fuscus繁殖期的现象学变化.
- 确定气候因素驱动两动物繁殖迁徙中观察到的现象学变化.
主要方法:
- 对意大利Pelobates fuscus的8年生殖迁移数据的分析.
- 对影响迁移时间的环境因素 (温度,湿度,降水) 的统计评估.
- 评估与气候变量相关的繁殖迁移现象学的长期趋势.
主要成果:
- 皮洛巴特的迁徙主要发生在春季初,在雨天,温度在9-14°C之间,湿度高.
- 尽管平均气温上升,但在8年内,在繁殖迁移的开始中观察到12.4天的延迟.
- 热和干燥的年份,而不是单独的温度上升,与延迟的迁移有关,这表明降水是短暂的池育种者的关键因素.
结论:
- 两动物的现象转变是复杂的,并不总是以早期的繁殖为特征.
- 降水模式在短暂的池繁殖两动物的现象学中可能比温度发挥更重要的作用.

Background and Environment Affect Phenotype
6.6K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Threats to Biodiversity
22.4K
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...

Hybrid Zones
17.1K
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.

What is Natural Selection?
115.5K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Responses to Heat and Cold Stress
13.6K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Frequency-dependent Selection
22.1K
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.
