概括

在天堂鸟中,Rensch的规则 (RR) 表明性选择驱动多妻性物种的性尺寸变态 (SSD). 然而,尾巴长度进化不遵循RR,这表明相关的男性和女性特征进化.

科学领域:

进化生物学进化生物学
宏观进化的模式
性选择性选择性选择

背景情况:

性选择的特征表现出极端的多样性和性变态.
伦什规则 (RR) 描述了一个宏观进化模式,将男性偏差二态与物种大小联系起来.
了解全度图案对于进化论对这些特征的洞察至关重要.

研究的目的:

在天堂鸟 (Aves:Paradisaeidae) 的尾巴长度进化中研究Rensch的规则 (RR).
检查性选择,性尺寸变态 (SSD) 和装饰性特征进化之间的关系.
测试装饰性形态特征中的RR及其与性二重形态的相互作用.

主要方法:

在天堂鸟种中分析尾巴长度和性二态度.
在单妻性和多妻性物种之间比较Rensch规则 (RR) 模式.
对雄性和雌性尾巴长度和身体尺寸的进化测量方法的检查.

主要成果:

在多妻性物种中观察到身体尺寸的Rensch规则 (RR),支持性选择作为驱动器.
尾巴长度进化不遵循Rensch规则 (RR),表明男性和女性具有相似的全度图案.
长尾物种中两性强烈的积极进化异位测量表明特征相关性,而不是约束,解释了缺乏RR.

结论:

性选择影响了Rensch规则 (RR) 的体型变异,特别是在多妻性物种中.
装饰性特征的进化,就像天堂鸟的尾巴长度,可能不会严格遵循Rensch的规则 (RR) 由于相关的性别特异性比度.
未来的研究应该整合SSD,二次性特征二重形和性别特异性全度,以充分理解宏观进化模式.

Mate Choice

Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

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...

Limits to Natural Selection

Limits to Natural Selection

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.

Testing a Claim about Mean: Unknown Population SD

Testing a Claim about Mean: Unknown Population SD

A complete procedure of testing a hypothesis about a population mean when the population standard deviation is unknown is explained here.
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...

Formation of Species

Formation of Species

Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.
