- 生物化学 生物化学
背景情况:
- 对于昆虫的发育和繁殖至关重要,特别是在以木为食的物种中.
- 长的社会性可能是通过与它们的祖先木食 (Cryptocercus) 相比,改变的分配而演变的.
- 加密虫表现出储存经济,在长时间的发展过程中大量投资于皮膜,而白则保持年轻的形式,通过社会行为如热和食人等保存.
研究的目的:
- 为了研究Cryptocercus punctulatus和木子Neot জীব jouteli中的经济.

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).

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...

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
