概括
在社会昆虫中,女王的多合性 (多重交配) 可以进化,以避免跨物种交配的负面影响. 这项研究发现,当本地大黄蜂女王与入侵物种交配时,它们会变得多.
科学领域:
- 生态生态学 生态生态学
- 进化生物学 进化生物学
- 行为生态学 行为生态学
背景情况:
- 一夫多妻制 (单一交配) 是社会女神的祖先,而多夫多妻制 (多重交配) 是一种衍生性特征.
- 多性恋在一些血统中很常见,比如蜜蜂和,这表明它具有健身优势.
- 侵袭性大黄蜂Bombus terrestris在日本表现出多性,与其单的本土种群不同.
研究的目的:
- 为了研究多夫合的假设,多夫合进化以减轻来自跨物种交配的生殖干扰.
- 在日本对入侵性Bombus terrestris和本地Bombus hypocrita亚种进行遗传研究.
主要方法:
- 对入侵性Bombus terrestris和本地Bombus hypocrita亚种 (B. h. sapporoensis和B. h. hypocrita) 的遗传分析.
- 基于与入侵物种的同情或异情的本地亚种的交配行为 (单恋与多恋) 的比较.
主要成果:
- 本土的Bombus hypocrita hypocrita女王,与B. terrestris共生,是严格的单一的.
- 本地Bombus hypocrita sapporoensis女王,与B. terrestris同情,表现出多姿态.
- 这些发现表明,B. h. sapporoensis女王不会因为与B. terrestris.的跨物种交配而遭受负面影响.
结论:
- 生殖干扰可能会推动同情物种中多的进化.
- 交配物种之间的进化军备竞赛可能会选择多重交配.

Pollination and Flower Structure
64.6K
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.

Mate Choice
8.0K
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.

Inclusive Fitness
36.0K
Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

Hybrid Zones
17.0K
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.

Genetics of Speciation
19.2K
Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

Frequency-dependent Selection
22.0K
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.
