翻译下这段吧
While such a system would not be of much use in tropical forests that are abruptly, and obviously, destroyed by human logging activity, audio recording systems could listen for changes in the symphony of cricket calls in forests that are starting to be fragmented by roads or becoming infiltrated by invasive species. Indeed, just as coalminers once knew that trouble was brewing if they heard a canary’s song abruptly stop, ecologists could eventually tell that ecosystem change is beginning to take place in a forest when they hear the chirps of key cricket species suddenly go silent.
虽然这种系统在遭到人类伐木活动突然破坏的热带森林中没有多大用处，但在开始遭到道路分割或入侵物种渗透的森林中，音频记录系统可以倾听蟋蟀交响乐的变化。事实上，就像煤矿工人一旦听到金丝雀的歌声突然停止，他们知道就会有麻烦一样，生态学家最终可以在听到关键蟋蟀物种的鸣叫声突然停止时，判断森林中的生态系统开始发生变化。
