Common filbert

<em>Corylus avellana</em> is a deciduous shrub or small tree in the family Betulaceae, order Fagales, commonly known as the common hazel or common filbert. The species is classified as Least Concern on the IUCN Red List, with widespread and stable populations across its native and introduced range. <em>Corylus avellana</em> is native to Europe and western Asia and has been introduced to parts of North America and South America. It is particularly associated with temperate deciduous woodlands, hedgerows, and scrubland across the Mediterranean forests and the Palearctic realm. The species typically forms a multi-stemmed shrub with broad, rounded leaves and catkins that emerge in late winter before the leaves appear, representing one of the earliest flowering events of the temperate year. Hazel nuts produced by this species are an important food source for woodland wildlife including squirrels, dormice, and woodpeckers. The species has been cultivated for centuries for nut production and coppicing. Biological traits of this species remain poorly documented in the scientific literature.

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.
