概括
拉纳病毒感染改变了幼虫两动物生长和发育之间的权衡. 这种感染成本影响了资源分配,影响了生存率和病毒载量,不同于仅靠新陈代谢预测的情况.
科学领域:
- 生态学和进化生物学
- 动物生理学 动物生理学
- 传染病生态学传染病生态学
背景情况:
- 生命史上的权衡,特别是生长和发育之间的权衡,在幼虫阶段至关重要,受到环境因素的影响.
- 年轻动物的能源预算主要用于生长和发育,由于资源竞争,可能会影响免疫功能.
研究的目的:
- 为了调查生长和发育中的种内变异如何影响幼虫两动物的新陈代谢.
- 确定生长,发育和代谢率是否预测感染拉纳病毒的幼虫的死亡率和病毒载量.
- 为了比较拉纳病毒感染前后生长和发育之间的关系.
主要方法:
- 测量了幼虫两动物生长速度,发育速度和代谢速度的种内特异变化.
- 在受感染和未受感染的幼虫两动物中评估死亡率和拉纳病毒病毒载量.
- 在拉纳病毒感染之前和之后,比较了幼虫生长和发育之间的权衡.
主要成果:
- 增长和发育速度的特定变化没有影响新陈代谢.
- 增长率,发育率和代谢率并不能预测拉纳病毒引起的死亡率或病毒载量.
- 发育和生长速度之间的权衡在感染拉纳病毒的幼虫中出现,但在未感染的幼虫中没有.
结论:
- 拉纳病毒感染给幼虫两动物带来了代价,改变了资源分配的优先级.
- 这种成本很可能是由于感染引起的厌食症和对抗感染的精力需求.
- 该研究强调了取决于背景的生命历史权衡以及病毒感染对宿主生理学的复杂影响.

Factors Affecting the Risk of Infection
11.8K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Competition
21.7K
When organisms require the same limited resources within an environment, they may have to compete for them. Competition is a net-negative interaction. Even if two competing individuals or populations do not interact directly, the overall fitness of both competitors is lowered as a result of not having full access to the limited resource.

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.
