chittamwood

Chittamwood or American Smoke Tree (Cotinus obovatus) is a large shrub or small deciduous tree in the family Anacardiaceae, native to scattered limestone outcrops and rocky woodlands across the south-central United States, occurring disjunctly in Alabama, Tennessee, Arkansas, Missouri, Oklahoma, and Texas. It is closely related to the ornamental European Smoke Tree (Cotinus coggygria), and like its relative, it produces spectacular autumnal foliage in brilliant shades of orange, red, and purple. The common name smoke tree or chittamwood refers to the large, feathery, smoky-looking inflorescences produced by the many elongated, pedicellate sterile flowers of the fruit cluster, which create a hazy, cloud-like appearance over the plant in late spring and summer. The trunk and branches exude a yellow-orange dye historically used by Native American peoples for colouring textiles and leather. Cotinus obovatus grows on thin, dry, calcareous soils where competition from larger forest trees is limited, often on south-facing slopes and cedar glades. Its naturally fragmented distribution has ecological significance as a refugia species on harsh substrates. The IUCN lists it as Least Concern; while rare across much of its range, it is locally abundant in favourable habitats. It is valued horticulturally for its outstanding autumn colour and drought tolerance.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
