概括

雄性和雌性 (Manduca sexta) 在储存花蜜糖的方式上有所不同. 虽然两性都在脂肪体中储存糖分,但男性优先考虑更早和更长的飞行肌肉,而飞行对女性的影响更大.

科学领域:

* 昆虫学昆虫学
* 昆虫生理学昆虫生理学
* 授粉生物学授粉生物学

背景情况:

*花蜜的消费和分配会影响授粉者的适应性和食.
* 在Lepidoptera中,花蜜分配策略的性别特异性差异尚未得到充分理解.
*Manduca sexta (Sphingidae) 是重要的授粉者,这使得它们的生理学具有重要意义.

研究的目的:

* 调查Manduca sexta.的作物空化率和花蜜糖分配情况.
* 确定性和飞行活动如何影响这些生理模式.
* 了解蝶中特定于性别的花蜜分配策略.

主要方法:

* (Manduca sexta) 吃了一顿甜蜜饭.
* 固定间隔的剖析测量了作物体积和糖分配到飞行肌肉和脂肪体.
* 两性静止和飞之间进行了比较.

主要成果:

* 两种性别都优先将花蜜糖分配给脂肪体而不是飞行肌肉.
*糖分在作物清空期间分配给脂肪体,并长期保留.
*男性比女性更早地将糖分分配给飞行肌肉,并保留它们的时间更长.
* 飞行增加了女性的作物清空,但不是男性.
* 飞行并没有显著改变任何性别的飞行肌肉或脂肪的分配.

结论:

*男性和女性蜜糖糖分配策略存在固有的差异.
*在作物空化的性别特异性取决于飞行活动的上下文.
*这些生理变异可能与雄性和雌性的不同健身最大化策略有关.

Pollination and Flower Structure

Pollination and Flower Structure

Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.

Energy Budgets

Energy Budgets

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

Production Efficiency

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).

Epiphytes, Parasites, and Carnivores

Epiphytes, Parasites, and Carnivores

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

Ecological Niches

Ecological Niches

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.
