概括

在家养的金丝雀中,更大的深度有助于处理大种子,而形状的变化不会显著影响小种子的处理,这表明该物种内部的力量-速度权衡.

科学领域:

* 鸟类生物学 * 鸟类生物学
* 功能形态学 * 功能形态学
* 生物力学生物力学

背景情况:

* 粮食类歌鸟表现出与种子专业化相关的多样化的形态.
* 子的大小和形状通常与处理不同种类的种子有关,反映了力-速度权衡.
* 甲形态的物种内变异可能会影响养性能和动力学.

研究的目的:

* 调查家养金雀 (Serinus canaria) 中的甲形态和养性能之间的关系.
* 为了研究形状的变化如何影响不同种子大小的动力学和种子脱皮效率.
* 测试子函数中一种种内力-速度权衡的假设.

主要方法:

*使用传统测量和3D地标分析对87只养的金丝雀中形状的分析.
*量化小金丝雀种子和大麻种子剥皮过程中的养性能和部动力学.
*形态指标 (深度,长度,宽度,曲率) 与养数据的相关性.

主要成果:

* 绝对深度较大的个体表现出更快地去皮大麻种子.
*在浅或长的嘴巴中,更高的嘴巴打开-关闭频率并没有显著减少小种子的加工时间.

Optimal Foraging

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

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...

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Migration

Migration

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

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.

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.
