Common Timothy

<em>Phleum pratense</em>, commonly known as common timothy or timothy grass, is a perennial grass in the family Poaceae widely cultivated and naturalized throughout temperate regions of the world. Native to most of Europe and western Asia, it has been introduced to North America, South America, New Zealand, and Australia, where it is now naturalized across vast areas. Timothy grass typically grows in meadows, pastures, roadsides, and disturbed habitats, thriving in well-drained to moderately moist soils at a broad range of elevations. It forms dense tufts with erect culms reaching up to 150 centimeters in height, topped with distinctive cylindrical, spike-like panicles that ripen to a straw-yellow color in summer. The species is one of the most important forage grasses globally, extensively cultivated for hay and silage production for livestock, particularly horses and cattle. It is also a significant source of allergenic pollen and is a major cause of hay fever in many parts of the world. <em>Phleum pratense</em> is currently assessed as Least Concern by the IUCN. Its conservation status is stable given its widespread distribution, high adaptability, and continued cultivation. Biological traits such as average lifespan under natural conditions, individual weight, and detailed growth parameters remain variable and context-dependent across populations.

アオフタオハチドリ

ナガオシルフハチドリ(Aglaiocercus kingii)は最も鮮やかに装飾されたハチドリの一つで、雄は虹色の緑色羽毛と22cmに達するリボン状に長く伸びた外側尾羽を持ち、これは体長の3倍を超える。コロンビアとベネズエラのアンデス雲霧林の標高1,400〜2,800mに生息し、雄は雌を引き付けるために精巧な誇示飛行を行う。その華麗な尾羽は、雌の選好による性的選択の古典的な例である。
