Habitat & Geographic Range
Common Velvetgrass
Typically found in grasslands, wetlands, forests, and cultivated landscapes.
Widely distributed across Africa (5 countries), Asia (6 countries), Europe (8 countries), North America (4 countries), Oceania and the Pacific (Australia, New Zealand), and South America (5 countries).
Emperor Penguin
Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.
Found in Norway. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.
Common Velvetgrass
<em>Holcus lanatus</em>, commonly known as common velvetgrass or Yorkshire fog, is a perennial grass in the family Poaceae native to Europe and western Asia that has become widely naturalized across temperate regions of North America, South America, New Zealand, and Australia. The species derives its common name from the soft, velvety texture of its leaves and stems, produced by a dense covering of fine hairs. <em>Holcus lanatus</em> typically grows in moist meadows, pastures, roadsides, forest clearings, and disturbed habitats, tolerating a wide range of soil conditions from acidic to neutral and from moist to moderately dry. It forms loose tufts with erect or spreading culms reaching up to 100 centimeters in height, topped with soft, pinkish-gray panicles during the summer flowering period. In its introduced range, particularly in New Zealand and parts of North America, velvetgrass is considered an invasive weed that displaces native plant communities in pastures and natural areas. The species is also known to cause allergic reactions in sensitive individuals due to its wind-dispersed pollen. <em>Holcus lanatus</em> is currently assessed as Least Concern by the IUCN. Its populations are abundant and expanding globally. Biological traits such as average individual lifespan, precise culm height ranges, and seed output per plant remain variable and poorly documented at the individual level.
Emperor Penguin
세계에서 가장 큰 펭귄인 황제펭귄(Aptenodytes forsteri)은 키가 최대 1.2m에 몸무게가 45kg에 달하며, 지구상에서 가장 혹독한 환경인 남극 대륙에 서식합니다. 영하 60°C 이하의 한겨울 암흑 속에서 번식하며, 수컷이 암컷이 바다에 있는 동안 65일 동안 발 위에서 육아낭 아래에 알 한 개를 품습니다. 수천 마리가 모인 무리에서 개체들이 따뜻한 중심부를 순환하는 이른바 허들링 행동은 협동적 생존의 훌륭한 사례입니다.
