Formation of Species01:31

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.

Genetics of Speciation02:16

Genetics of Speciation

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.
Types of Selection01:46

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...
Mate Choice01:20

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.
Frequency-dependent Selection01:21

Frequency-dependent Selection

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.

  • 進化生物学の進化生物学について
  • 鳥類学 鳥類学とは,鳥類学である.
  • 仕様 研究 研究 仕様

背景:

  • カラーポリモルフィズムは,集団内の多様な色のパターンによって特徴付けられ,分類学的に広く普及しているが,一般的に稀である.
  • 理論的なモデルは,色彩の多形態化が種種を駆動することができると示唆しているが,この一般性に対する経験的証拠は限られている.

研究 の 目的:

  • 鳥類ファミリーにおける色多型化と種種化率の関連性を調査する.
  • カラーポリモルフィズムの進化的動態を決定し,その増減率を含む.
  • カラーポリモルフィズムが種化を促進するという仮説を検証する.

主な方法:

  • 5つの非渡り鳥の家族のための種レベルの分子系統の構築と分析.
  • ポリモルフとモノモルフの種における種種化と絶滅率の評価のための系統遺伝学的比較方法.
  • ポリモルフとモノモルフの種の年齢を比較するために,パセリンの大規模フィロゲーニーの分析.

  • カラーポリモルフィズムは,それが最も一般的である鳥群の特異化率の加速と関連しています.
  • 色彩ポリモルフィズム (モノモルフィズムへの移行) の喪失率は,色彩獲得率を大幅に上回ります.
  • ポリモルフの鳥類は,進化的にはモノモルフの種よりも若いので,最近の多様化に役割を果たしています.
