概括
龙的翅膀颜色因飞行风格和温度而异,在寒冷的气候和雄性中翅膀较暗. 较深的颜色可能有助于温度调节,而较浅的颜色则没有. 性别在翅膀颜色上只有在息物种中才有区别.

背景情况:
- * 昆虫的颜色具有多种功能,包括视觉信号和温度调节.
- * 鸟 (龙和) 翅膀颜色研究在很大程度上专注于黑色,忽视多彩的翅膀和广泛的比较分析.
- * 尽管有潜在的温度调节和信号影响,但鸟飞行风格 (鸟与飞行员) 和翅膀颜色之间的关系仍然未被探索.
研究的目的:
- * 为了全面量化和分析近北奥多纳塔物种的大数据集中的翅膀颜色变化.
- * 调查环境 (温度),形态 (体型),行为 (飞行风格) 和性因素对翅膀颜色的影响.
- * 测试关于不同翅膀颜色在温度调节和性信号中的作用的假设.
主要方法:
- *利用一种新的色彩聚类算法,分析了来自近北极343种臭虫物种的8000多张翅膀图像.
- * 采用了基因组学信息的贝叶斯式零膨胀混合物模型来评估颜色变异驱动因素.
- * 检查了翅膀颜色 (浅棕-黄色,黑色-深棕) 和环境温度,身体大小,性别和飞行风格等因素之间的关系.
主要成果:
- * 臭的翅膀色彩广泛聚集在浅棕-黄色和黑色-深棕色的群体.
- *雄性鸟和翅膀较长的物种呈现出更高比例的黑色深棕色.
- * 黑色-深棕色的色彩在寒冷的气候中更为普遍,但其比例与温度无关;浅棕-黄色没有显示温度相关性.
- * 翅膀颜色的两性变态仅在鸟种中观察到.
结论:
- * 黑色至深棕色的翅膀颜色可能在较凉爽的环境中在odonates的温度调节中起到有限的作用.
- * 浅棕黄色的颜色似乎没有显著的温度调节功能.
- * 鸟物种中两性之间分歧的翅膀颜色表明它们在性选择和信号传递中发挥了作用,特别是在领土雄性中.

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.

Background and Environment Affect Phenotype
6.5K
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...

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.

Pollination and Flower Structure
63.5K
Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.

Frequency-dependent Selection
21.9K
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.
