- 生态生态学 生态生态学
背景情况:
- 生理压力对动物需要大量的能量资源.
- 动物可以通过调整食行为或保留营养素来应对压力.
- 作为应激反应的营养保留是一种研究不足的机制.
研究的目的:
- 为了检查高生理应激对 (Psammophilus dorsalis.alis) 中元素 (碳和) 保留的影响.
- 为了确定压力是否会影响身体保留摄入营养素的能力.
主要方法:
- 成年被分为压力 (每日约束) 和对照组10天.
- 在治疗期间之前和之后测量了皮质,葡萄糖和甘油三水平.
- 保留的碳和总量是根据摄入和消化量计算的.
主要成果:
- 两组都显示出皮质水平的增加,而压力较大组的男性呈现出最大的上升.
- 葡萄糖和甘油三水平显示出变化.

02:12What Are Osmoregulation and Excretion?
37.9K
Organisms must keep bodily fluids at a constant temperature and pH while maintaining specific solute concentrations in order to support life functions. Osmoregulation is the process that balances solute and water levels.

02:32Osmoregulation in Fishes
52.8K
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

01:21Skeleton and Calcium Homeostasis
5.8K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

01:01Production Efficiency
18.2K
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).

02:24Comparative Excretory Systems
26.5K
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.

01:27The Periodic Table and Organismal Elements
22.2K
Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.
