- 動物の行動 動物の行動
背景:
- Cnemidophorus uniparensの生殖サイクルには,自然に季節的な耐火期,すなわち生殖活動の一時停止が含まれる.
- この耐火期を調節する環境と内部のシグナルを理解することは,タカの生殖戦略を理解するために不可欠です.
研究 の 目的:
- Cnemidophorus uniparens.の繁殖不耐期の終結における光周期と内生的なコントロールの役割を調査する.
- 耐火期が主に内生的な制御下にあるという仮説を検証するために,外部の光線から独立して.
主な方法:
- 繁殖後のCnemidophorus uniparensは,恒常的な暗闇と長い光期という2つの条件の下で維持されました.
- 実験グループは7ヶ月間絶えず暗闇に放置され,対照群は長い光期に曝された.
- 実験期間中,両方のグループで生殖状態が監視されました.
主要な成果:
- 実験群 (恒常的な暗闇) と対照群 (長い光期) は12月に同時に生殖活動を開始した.
- これは,実験グループが9月から暗闇の中にいたにもかかわらず起こりました,これは耐火期の典型的な始まりです.
- 断裂性の終結と生殖の開始は,グループ間で同期されました.
結論:
- この発見は,Cnemidophorus uniparensの生殖耐久期が内生的な制御下にあるという仮説を強く支持しています.
- 光周期のような外部要因は,この耐火期の終結の主な要因ではないようです.
- これは,内部生物学的時計が,この種の生殖準備のタイミングを決定することを示唆しています.

Circadian Rhythms and Gene Regulation
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent years,...
Biological Clocks and Seasonal Responses
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.
Hormonal Control of the Ovarian Cycle
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Feedback Regulation of Calcium Concentration
Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

Energy Budgets and Reproductive Strategies
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 reproduce only once in their lifetime, often investing most available resources into that single reproductive event. Iteroparous species, by contrast, reproduce multiple times over their lifetimes, typically allocating fewer resources to any single...
