概括
由性选择驱动的男性侵略性可能会减少个体的生存率,但可能会增强人口对环境压力的弹性,例如几代人的热浪. 这项研究探讨了它对面临高温的虫种群的影响.
科学领域:
- 进化生物学是进化的生物学.
- 生态生态学 生态生态学
- 环境科学环境科学
背景情况:
- 性选择会影响生存和健康,有时会造成性冲突.
- 热浪等环境压力因素对人口构成风险,特别是小型的危物种.
- 在压力下,性和环境选择之间的相互作用对于人口的持续性至关重要.
研究的目的:
- 调查男性侵略如何影响环境压力期间的人口生存.
- 了解性选择 (男性侵略) 和环境压力 (热浪) 对人口人口结构的综合影响.
主要方法:
- 在 *Sancassania Berlesei* 虫种群中使用费洛蒙线索操纵男性侵略水平.
- 在八代人中暴露于反复出现的极端热情事件的人口.
- 监测人口生存率与战斗机变形流行率和热量暴露相关.
主要成果:
- 暴露于热量会降低生存率,特别是在女性身上.
- 较高的侵略性男性患病率与较低的人口存活率相关.
- 跨世代生存率的下降在具有较少侵略性雄性的人群中更为.
- 三个男性侵略性减少的群体在热应激下灭绝.
结论:
- 随着时间的推移,男性侵略的个人生存成本并没有使人口对热浪的敏感性恶化.
- 与男性侵略性相关的死亡成本在几代人之间得到了补偿,可能是通过同胞繁殖抑郁症清除.
- 性选择虽然带来短期的人口风险,但可能会增强人口对长期环境压力的抵抗力.

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.

Aggression
30.1K
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Background and Environment Affect Phenotype
7.4K
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...

Spermatogenesis
122.0K
Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male...

Natural Selection and Mating Preferences
483
The principle of natural selection posits that organisms better adapted to their environment are more likely to survive and reproduce. This principle is closely intertwined with mating preferences, a key aspect of sexual selection, which evolutionary psychologists believe is driven by instincts to propagate one's genes. Such instincts significantly influence mating behaviors and preferences between genders.

Population Growth
27.8K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.
