题型分类：主旨题
题干分析：讲座主旨。
原文定位：
An invasive species is a non-native species whose introduction to an area causes economic or environmental harm. A classic case of an invasive species is a type of shellfish called zebra mussel.
选项分析：文章开头提到入侵生态学很重要，随后提到其中一个经典例子就是斑马螺，随后整篇文章主要都在讲斑马螺相关的话题，可知应选C选项。A选项在文章中未提及，B、D选项都仅是文章的一小部分。
