- 两动物生物学
- 环境科学 环境科学
背景情况:
- 水生生态系统中的可变水周期对具有复杂生命周期的生态热生物构成风险.
- 发育性可塑性可以帮助物种适应环境干燥,但可能会产生健康成本.
研究的目的:

- 为了确定在干旱条件下加速发展是否会影响变形体的大小和运动能力.
主要方法:
- 模拟干旱条件 (干燥池) 和稳定的低水位被用来治疗.
- 发育速率,变形大小和跳跃性能被测量和在治疗过程中进行比较.
主要成果:
- 在干燥条件下的子表现出较快的发展速度,而不是在稳定的低水.
- 变形体的大小在干燥和高水处理中是相似的,但在干燥处理中跳跃性能较低.

Energy 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...

Production Efficiency
16.7K
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

Comparative Excretory Systems
19.0K
Animals have evolved different strategies for excretion, the removal of waste from the body. Most waste must be dissolved in water to be excreted, so an animal’s excretory strategy directly affects its water balance.
