苔原

We found potential evidence of a severe population bottleneck in the cave lion during the previous interstadial, sometime after 48 000 years, adding to evidence from bison, mammoths, horses and brown bears that megafaunal populations underwent major genetic alterations throughout the last interstadial, potentially presaging the processes involved in the subsequent end-Pleistocene mass extinctions.

这些生活在不列颠群岛以及欧洲和北美地区的狮子的生存环境与目前非洲的大型猫科动物完全不同：在更新世，英国是苔原冻土地带，就像现在的俄罗斯草原一样，很多大型动物聚集那里，如哺乳动物、羊毛犀牛、巨型鹿等。13000年前，这些狮子和大型食草动物在大灭绝中消失。

"全球变暖观察"是美国蓝色地球联盟的一个研究项目，该网站提供了有关全球变暖的图片和说明，包括冰川消退、苔原消失、海平面上升、干旱、珊瑚死亡等，这些图片通过不同的专题保存，比如地区、事件、温度带等。

It's a splendorous landscape, dynamic and rich, tumultuous and delicate, encompassing 2.8 million acres of volcanic mountains and forest and tundra and river bottoms as well as more than 700 brown bears, thickets of Siberian dwarf pine and relict "graceful" fir left in the wake of Pleistocene glaciers, a major rookery of Steller sea lions on the coast, a population of kokanee salmon in Kronotskoye Lake, along with sea-run salmon and steelhead in the rivers, eagles and gyrfalcons and wolverines and many other species—terrain altogether too good to be a mere destination.

By using the method of comparative geography, the continuity and discontinuity between alpine meadow and its neighboring and alike landscapes have been studied in order to indicate that the alpine meadow zone is the transitional landscape from montane forest to alpine steppe and it can be regarded as a large altitudinal belt compared with the latitudinally distributed tundra on a global scale.

首先，用比较地理学的方法探讨了高寒草甸与其相邻和相似景观之间存在的连续性和间断性，说明地带性的高寒草甸景观是从山地森林景观向高寒草原景观的过渡；而在全球空间尺度范围内，作为"大垂直带"的高寒草甸，与纬向分布的极地苔原具有可比性。
