There is still no universally agreed-on explanation for why there should be such a dramatic cessation of tree growth at the upper timberline.
对于为什么树线以上的树木会突然停止生长，至今还没有一个公认的解释。
Without the right growing conditions, trees cannot get really big, and there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm.
没有合适的生长条件，树木就不能长得很高大。还有一些证据表明，在世界气候温暖的时候，尤其是在原本已经很温暖的环境里，树木的生长可能会放缓。
Insects and pathogens are integral components of forest ecosystems and normally are present at a relatively low density, causing little damage, and having negligible impact on tree growth and vigour.
昆虫和病原体是森林生态系统的固有成分，通常其密度相对较低，所造成的损害较小，对树木生长及其活力的影响微乎其微。
