まとめ
海洋温度の上昇は オリーブリドリー海の巣作りに悪影響を及ぼします この研究では,海面の温度と巣づくりの間の期間との間に有意な相関がみられ,巣づくりの現象に影響を与えました.
科学分野:
- 海洋生物学
- 気候変動 エコロジー
- 保護科学
背景:
- 気候変動は海の個体数に影響を及ぼし 温度は巣作りの行動に影響を及ぼします
- 以前の研究では,オリーブリドリーカメの温度とIPの相関性は示されませんでした.これは,サンプルサイズが小さいためかもしれません.
研究 の 目的:
- 海面温度とオリーブリドリーカメの巣間期間 (IP) の関係を調査する.
- 温度上昇がオリーブ・リドリーの 巣を作る現象に 影響するかどうかを調べるため
主な方法:
- コスタリカのオリーブリドリーカメ96匹の捕獲・再捕獲データから 14年間を活用しました
- NASAの高解像度センサデータを用いて,インターネスティング期間の平均海面温度 (SST) を計算した.
- SSTとIP間の関係を分析した.
主要な成果:
- SSTとIPの間には統計的に有意な負の関係が見られた.
- 平均IPは22. 5±6. 0日,平均SSTは28. 0±0. 6°Cでした.
- オリーブ・リドリーの巣作りのタイミングに 高い温度が影響していることが 示唆されています
結論:
- オリーブリドリーカメは,以前の仮定に反して,温度に依存する巣間期間を示します.
- 気候変動による温暖化により オリーブリッドリーの巣立つの時期や アリバダのタイミングが変わる可能性があります
- この研究は,オリーブリドリーカメが 気候変動による生殖への影響に対して 脆弱であることを強調しています

Background and Environment Affect Phenotype
6.7K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Global Climate Change
24.7K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Increased Body Temperature
1.8K
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

The Collision Theory
Atoms, molecules, or ions must collide before they can react with each other. Atoms must be close together to form chemical bonds. This premise is the basis for a theory that explains many observations regarding chemical kinetics, including factors affecting reaction rates.
The collision theory is based on the postulates that (i) the reaction rate is proportional to the rate of reactant collisions, (ii) the reacting species collide in an orientation allowing contact between...
