概括
海洋酸性极端事件对马尼拉的繁殖有负面影响. 母亲的影响,而不是帮助后代,可能会通过耗尽必要的能量储备来阻碍幼虫的发展,这表明对气候变化的不适应.
科学领域:
- 海洋生物学 海洋生物学
- 生态毒理学 生态毒理学
- 气候变化科学 气候变化科学
背景情况:
- 极端海洋酸度 (OAX) 事件威胁到沿海生态系统和海洋双动物.
- 众所周知,母亲的影响会影响后代对环境压力因素的反应.
- 双动物对母体对OAX的影响的适应能力在很大程度上是未知的.
研究的目的:
- 调查OAX对马尼拉的父母和幼虫脂质体的影响.
- 在OAX条件下阐明母体效应的能量基础.
- 确定母体影响是否会使后代对OAX.产生抗药性.
主要方法:
- 暴露成年马尼拉 (Ruditapes philippinarum) 在OAX条件下.
- 分析了受压力的成年人和他们的后代幼虫的脂质特征.
- 脂质成分的量化变化,重点关注糖脂和三糖醇.
主要成果:
- 经过OAX压力的成年人显示了177种脂质成分的显著下调,主要是甘油脂.
- 来自暴露于OAX的父母的幼虫表现出糖脂的进一步下调.
- 来自条件父母的幼虫具有较低的三甘油含量和改变的脂肪酸概况,增加了二甘油副产品.
结论:
- 在OAX下的母体影响可能是不适应性的,减少了幼虫的能量储备.
- 父母和后代的脂质代谢变化表明能量转移受损.
- 对于面临OAX.的马尼拉贝来说,母性影响不太可能是适应策略.

11.6K
Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

00:51Energy Budgets
9.2K
Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...
