概括
费尔的叶子子显示出与植物化学物质摄入相关的受孕峰值,而不是能量平衡. 这种时间并没有改善这个灵长类动物的婴儿存活率或间隔间隔.
科学领域:
- 灵长类的生殖生态学
- 哺乳动物的生殖策略
- 野生动物保护生物学
背景情况:
- 哺乳动物的繁殖季节性通常与养育后代的能量可用性有关.
- 植物化学物质可能会影响哺乳动物的受孕时间.
- 了解影响灵长类繁殖的因素对于保护至关重要.
研究的目的:
- 为了研究Phayre叶 (Trachypithecus phayrei crepusculus) 怀孕峰值的驱动因素.
- 评估能量平衡与植物化学品摄入量在季节性怀孕中的作用.
- 为了确定受孕时间是否会影响婴儿存活率和分娩间隔.
主要方法:
- 现场数据收集的78个概念在福开野生动物保护区,泰国.
- 通过水果/叶子的可用性和月率估计的能量摄入量.
- 从便中的孕激素水平推断出的植物化学物质摄入量.
- 使用循环统计和考克斯比例危险模型分析季节性.
主要成果:
- 怀孕从5月到8月达到峰值,与高便孕激素 (植物化学物质摄入) 相相关.
- 没有一个明确的正能量平衡时期与概念峰值相吻合.
- 原生雌性比多生雌性晚怀孕.
- 怀孕时间没有显著影响婴儿存活率或分娩间隔.
结论:
- 植物化学物质的摄入量,而不是能量平衡,似乎在这种叶群体中驱动着怀孕峰值.
- 观测到的概念集群可能是季节性植物化学品消费的副产品.
- 需要进一步研究直接测量季节性植物化学物质和激素水平.

Energy Budgets
9.3K
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...

Biological Clocks and Seasonal Responses
34.7K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Overview of Metabolism
30.4K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Phloem and Sugar Transport
37.4K
Like many living organisms, plants have tissues that specialize in specific plant functions. For example, shoots are well adapted to rapid growth, while roots are structured to acquire resources efficiently. However, sugar production is primarily restricted to the photosynthetic cells that reside in the leaves of angiosperm plants. Sugar and other resources are transported from photosynthetic tissues to other specialized tissues by a process called translocation.

Light Acquisition
8.5K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Seed Structure and Early Development of the Sporophyte
28.3K
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.
