概括

城市化对女童的生命历史特征产生影响,反应因度,温度和性别而异. 侵入性捕食者也会影响生长,但随着气温的升高,这些影响会发生变化,尤其是在高度群体中.

科学领域:

生态生态学生态生态学
进化生物学进化生物学
环境科学环境科学

背景情况:

物种正在适应不同度的城市环境.
城市适应涉及受到温度和入侵物种影响的生态进化变化,这些变化可能在地理上有所不同.

研究的目的:

为了研究温度升高和侵入性掠食者对花表型的影响.
为了比较城市和农村人口之间的这些影响,跨越中部和高度.

主要方法:

从中部和高度的城市和农村池中获得的小鸟幼虫 (Ischnura elegans) 被暴露在不同的温度处理 (20°C,24°C,28°C) 中.
幼虫还暴露于来自入侵性刺脸 (*Faxonius limosus*) 或对照的化学线索.
测量了发育时间,质量和生长速度.

主要成果:

城市化影响了所有测量的生命历史特征,反应取决于度,温度和性别.
温和的变暖减少了农村人口的质量,增加了城市人口的增长率.
捕食者线索在当前和温和的变暖温度下降了生长率,但在高度的女中,在热浪期间增加了生长率.

结论:

对城市化的进化和塑性反应取决于环境.
基于单一度的城市适应的普遍化是值得谨慎的.
城市化,气候变化和入侵物种之间的相互作用塑造了物种的适应战略.

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

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...

Types of Selection

Types of Selection

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...

Gene Flow

Gene Flow

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