chittamwood

Chittamwood (Sideroxylon lanuginosum), also called Gum Bumelia or Gum Elastic, is a thorny shrub or small tree in the family Sapotaceae, native to the south-central and southeastern United States and extending into Mexico. It typically grows in dry to moderately moist soils in open woodlands, cedar glades, bottomland margins, and disturbed habitats across a range from Kansas and Missouri south through Texas and east to Georgia and Florida. The species produces small, white, fragrant flowers in clusters along the branches, followed by small black drupes relished by wildlife including thrushes, mockingbirds, and small mammals. The latex-containing bark and twigs are notably sticky, earning it the vernacular name gum elastic, and the wood is hard and dense. Leaves are simple, alternate, and elliptical, often with a silvery or woolly texture when young due to dense hair cover. In Texas and Oklahoma, chittamwood is a characteristic component of the Cross Timbers and South Texas Plains vegetation communities. The IUCN classifies it as Least Concern given its broad range and general abundance. While it may be locally impacted by land clearing and range management practices, the overall species is not considered threatened. It provides important ecological services as a thorny refuge plant and a food source for birds and small mammals.

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。
