ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

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.
