African elephant

地球上最大の陸上動物であるアフリカゾウは体重7,000 kgに達し、サハラ以南のサバンナ、森林、湿地に生息する。成熟した雌が群れを率いる高度に知的な社会構造を持ち、超低周波音やうなり声、接触によって意思疎通する。木を引き倒したり水飲み場を掘ったり種子を散布したりすることで生態系を形成するエンジニア種だが、象牙の密猟や生息地の喪失により個体数は減少しており、危急（VU）とされている。

Christmas Cactus

The Christmas cactus (Schlumbergera truncata) is a species of epiphytic cactus in the family Cactaceae, native to the coastal mountains of southeastern Brazil, particularly in the state of Rio de Janeiro. It is one of the most widely cultivated ornamental cacti in the world, grown commercially under the names Thanksgiving cactus or Christmas cactus, and is the primary parent species of the numerous hybrid Christmas cacti available in horticulture. In nature, Schlumbergera truncata grows as an epiphyte in humid Atlantic Forest, attached to tree branches in areas receiving abundant rainfall and fog. Its flattened, segmented stems — phylloclades — have distinctive claw-like teeth along their margins, which distinguish it from the more rounded segments of Schlumbergera bridgesii. Flowers are produced at stem tips in autumn and early winter and range from white through pink, red, purple, and orange, adapted for hummingbird pollination. In cultivation, flowering is induced by exposure to long nights and cooler temperatures. The species tolerates a wider range of conditions than its native epiphytic habitat might suggest, explaining its success as a houseplant globally. In its native Brazilian Atlantic Forest, it faces threats from continued deforestation.
