- 进化生物学 进化生物学
- 人口动态 人口动态
背景情况:
- 群体内部和群体之间的表型变化驱动着人口对环境变化的反应.
- 部分迁移人口依赖于迁移与居住的适应表达,特别是在生命早期.
- 关于早期迁移动态和选择的有限数据阻碍了对适应表达的理解.
研究的目的:
- 量化早期生活中迁移与居住的变化以及欧洲人中相关的生存率.
- 评估在队列和年内和跨年迁移的适应性表现形式表达的程度.
- 调查早期生活迁移中生存选择的动态.
主要方法:
- 利用了来自11个队伍的9359只彩色环状幼年欧洲 (Gulosus aristotelis) 的全年广泛的现场重新定位.
- 应用贝叶斯多态捕获-标记-重新捕获模型来分析数据.
- 量化迁移,居住和生存在短暂的时间场合在飞行后的第一年内.
主要成果:
- 所有队列都表现出部分迁移,迁移时间和程度在队列内和队列之间有显著的变化.
- 强烈的生存选择事件发生在短时间和累积时间尺度上,随着多年来波动的选择.
- 迁移程度与选择方向没有很强的相关性,这表明早期适应性表现型表达有限.
结论:
- 季节性迁移的早期表达和选择在多个时间尺度上都是动态的,但可以脱.

Migration
7.9K
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.

Limits to Natural Selection
31.2K
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.

Gene Flow
35.0K
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Types of Selection
40.3K
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...
