Coahuila-Texas Yucca

Yucca coahuilensis, the Coahuila-Texas yucca, is a striking succulent plant in the family Asparagaceae native to the Chihuahuan Desert along the border region of Coahuila state in northeastern Mexico and adjacent southwestern Texas. The species occupies arid to semi-arid shrubland, desert grassland, and limestone hillsides where it grows on rocky, well-drained soils in areas receiving low and highly seasonal rainfall. Like all yuccas, Y. coahuilensis produces a rosette of stiff, sword-like leaves with sharp terminal spines and a tall flowering stalk bearing large, bell-shaped white flowers that are pollinated almost exclusively by yucca moths in the genus Tegeticula, with which the plant maintains an obligate mutualistic relationship. The moth larvae feed on developing seeds while simultaneously pollinating the flowers, a system representing one of the most tightly co-evolved plant-pollinator mutualisms in North America. Yucca coahuilensis is classified as Vulnerable by the IUCN, reflecting its restricted range in a binational border region subject to habitat alteration from ranching, agricultural expansion, and changing precipitation patterns associated with climate change in the Chihuahuan Desert ecosystem.

コウテイペンギン

世界最大のペンギンであるコウテイペンギン（Aptenodytes forsteri）は体高最大1.2m、体重45kgで、地球上で最も過酷な環境の一つである南極大陸に生息しています。零下60°C以下の真冬の暗闇の中で繁殖し、雌が海上にいる間、雄が65日間足の上で育雛嚢の下に一つの卵を温め続けます。数千羽からなる群れで個体が暖かい中心部を循環するいわゆるハドリング行動は、協調的な生存戦略の傑作です。
