G.伊芙琳哈钦森,她的想法引起了轰动?受现代生态学的启发,他创造了一个术语“异生”来表示那些在黑暗、干旱、炎热或寒冷的极端环境中无法进行光合作用的地区,以及那些生命依靠外来物质维持生命的地区。异生圈的居住者生活在边缘,欣赏他们的遭遇,就是拓宽我们对主流的视野。对生物圈两个截然不同的组成部分,海洋深处和火山岛,最近的和持续的研究,正在独立地为充其量是模糊的异生物圈勾勒出更清晰的轮廓。我的目的是把这些完全不同的极端加以归类。
G. Evelyn Hutchinson, whose ideas have stir? lulated so much of modern ecology, coined the term allobiosp~ ere~ to denote regions where photosynthesis is precluded &y environmental extremes of darkness, drought, heat or cold, and where life depends for sustenance on imported materials. The occupants of the allobiosphere arc living on the edge; to appreciate their cinumstances is to broaden our perspective of Ihe mainstream. Recent and continuing studies on two contrasting components of the biosphere, the ocean depths and volcan ic islands, are independently giving sharper outline to what was at best a hazy sketch of the allobiosphere. My aim here is to kxtapose these radically different extreines.
