内容简介

A biologist reveals the secret world hidden in a single square meter of forest. In this wholly original book, biologist David Haskell uses a one- square-meter patch of old-growth Tennessee forest as a window onto the entire natural world. Visiting it almost daily for one year to trace nature's path through the seasons, he brings the forest and its inhabitants to vivid life. Each of this book's short chapters begins with a simple observation: a salamander scuttling across the leaf litter; the first blossom of spring wildflowers. From these, Haskell spins a brilliant web of biology and ecology, explaining the science that binds together the tiniest microbes and the largest mammals and describing the ecosystems that have cycled for thousands- sometimes millions-of years. Each visit to the forest presents a nature story in miniature as Haskell elegantly teases out the intricate relationships that order the creatures and plants that call it home. Written with remarkable grace and empathy, "The Forest Unseen" is a grand tour of nature in all its profundity. Haskell is a perfect guide into the world that exists beneath our feet and beyond our backyards.

读书文摘

但是,因为热爱自然便憎恶人类,这是不合逻辑的。人类是整体的一部分。真正爱这个世界,就也应该热爱人类的聪明才智和活泼嬉戏。自然界并不需要将人工制品清除出去才能变得美丽或是协调一致。没错,我们不该那么贪婪、不讲卫生、浪费成性、目光短浅。但是我们也不要把责任变成自我憎恶吧。归根结底,我们最大的缺点是对世界缺乏怜悯之心,甚至对自己也不例外。

一切物体,包括动物身体在内,体积的增量是长度增量的立方倍;而一只动物全身所能生成的热量,与其身体大小是成正比的;因此,体热的增长量,也是身体长度增量的立方倍。而在热量流失时,表面积的增量只是长度增量的平方倍。小动物的体温下降速度之所以更快,是因为按照比例来说,它们的体表面积远远大于身体体积。
