概括
女甲虫 (C. sexmaculata) 吃了丰富的,营养丰富的猎物,生殖腺明显更大,更重. 这说明了饮食的质量和数量如何影响昆虫的繁殖发育.
科学领域:
- 昆虫学 昆虫学是一门学科.
- 昆虫的生殖生物学 昆虫的生殖生物学
- 营养生态学 营养生态学
背景情况:
- 食物的可用性极大地影响了昆虫的生命史特征,包括繁殖.
- 虽然饮食对昆虫生殖产量的影响是已知的,但其对两性雌雄的生殖腺发育的直接影响是不太了解的.
- 雀甲虫 (C. sexmaculata) 显示猎物偏好,偏好营养丰富的Aphis craccivora,而不是质量差的Aphis nerii.
研究的目的:
- 为了研究饮食质量和数量的对女甲虫 (Cheilomenes sexmaculata) 性腺发育的影响.
- 测试假设丰富的,营养丰富的猎物导致C. sexmaculata更大,更重的性腺.
主要方法:
- 在整个生命周期中,在两种不同的饮食 (质量和数量变化) 上养C. sexmaculata幼虫.
- 每天对成年甲虫化后进行剖析,以评估生殖腺发育,体重和其他形态参数.
- 在治疗过程中量化淋巴体体重,淋巴体指数 (GSI),淋巴体区域,丸叶数和卵巢数.
主要成果:
- 饮食的质量和数量都显著影响了男性和女性C. sexmaculata的发育期,体重和生殖腺参数.
- 与有限或质量差的饮食相比,丰富的Aphis craccivora显著促进了生殖腺生长和发育.

02:27Background and Environment Affect Phenotype
6.4K
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...

01:32What is Natural Selection?
114.6K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.
