まとめ
タウニー・フローグマウスの雛は,目を開けた後に顔面の毛が生み出され,完全な発達は羽ばたき後に起こります. このタイミングは 鳥の毛皮が 独立して餌を探し 餌を与えるのに役立つことを示しています
科学分野:
- 鳥類の生物学
- 発達生物学
- 感覚エコロジー
背景:
- 鳥の顔の毛皮,特にの毛皮はよく見られるが,その機能と発達はまだよくわかっていない.
- 以前の研究では 毛が触覚的な役割を果たし 夜間の餌探しに役立つ可能性があるが 証拠は限られている.
研究 の 目的:
- 色のカエル口 (Podargus strigoides) の毛の発達時間軸を調査する.
- 毛の発達と 羽毛や目を開くなどの 重要な発達のマイルストーンを 関連付けること
- 鳥の餌探し行動におけるリクタルブラストの潜在的機能についての洞察を提供するためです.
主な方法:
- カエル口のニワトリの観察研究
- 羽毛,目開き,毛の出現を含む発達段階の文書化.
- 行動のマイルストーンに関連した毛の発達の質的評価
主要な成果:
- カエル口のニワトリは 顔の毛が抜けたまま 化します
- 眼の熟成後に毛の出現が観察された.
- 毛の完全な発達は,自立の餌と一致して,飛んだ後に達成されました.
結論:
- 色のカエル口の毛の発達のタイミングは,自立的な採食中に触覚感覚の認識における彼らの提案された役割を支持する.
- 幼鳥 が 独立 し て 餌 を 取っ て くる とき,リクタル の 毛皮 は 餌 を 取っ て 行く こと に 寄与 し て い ます.
- 鳥の顔の毛皮の感覚的メカニズムと 行動的統合を 完全に解明するためにさらなる研究が必要である.

Determination
19.1K
During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

Fixed Action Patterns
16.5K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Accessory Structures of the Skin: Hair and Hair Follicles
2.7K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Testing a Claim about Mean: Unknown Population SD
3.6K
A complete procedure of testing a hypothesis about a population mean when the population standard deviation is unknown is explained here.
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...

The Tongue and Taste Buds
37.4K
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.

Mate Choice
10.4K
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
