16 •Highly diverse species 种类组成丰富 Rainforests now cover less than 6% of Earth's land surface, but contain more than half of all the world's plant and animal species. Seventy percent of the plants in the rainforest are trees. Many vines and epiphytes grow in the rainforest. Dominant species do not exist in tropical rainforests. (Consist of many different species, but the same species are very seldom found growing close together. )
epiphytes (eg.orchids and bromeliads凤梨植物) 空中花篮一附生植物生长在乔木、灌术或藤本植物的枝叶上， 其组成从藻、菌、苔藓、蕨类到高等有花植物都有

Vines 发达的藤本植物一藤本多木本， 粗如绳索或电线杆，一般长70米左 右，有时达240米。小藤本多单子 叶植物或蕨类，一般不超出树冠荫 蔽的范围。 18

Strangler plants-These plants (eg.Ficus species)begin life as epiphytes,when their seeds,often bird-dispersed, germinate in crevices atop other trees.These seedlings grow their roots downward and envelop the host tree while also growing upward to reach into the sunlight zone above the canopy,finally kill the original support trees 绞杀植物一有的植物开始 附生在乔木上，以后气生 根下垂入士，营独立生 活，并常杀死藉以支持的 乔木，所以被称为“绞杀植 物”如榕属的一些种。 19
