请教

Although no one has quantified

changes in the rate of straying

as a result of the disturbances

caused by humans, there is no

(70) reason to suspect that the effect

would be qualitatively different

than what was seen in the

aftermath of the Mount
                    Saint

Helens eruption.   这句话是什么意思呢 怎么理解啊  谢谢了

Low levels of straying are crucial, since the process provides a source of novel genes and a mechanism by which a location can be repopulated if the fish there should disappear.

牛牛翻译下这句话咯。实在不明白。。
