1. Enter alien invaders in the search box to find articles with this phrase in the title, subject, or abstract.

2. Scroll down the list of results and notice different terms such as biological invasions and animal introduction as descriptors (DE).

3. Descriptors (aka subject headings) are words assigned by an indexer or author which describe the main points of the article. Searching using descriptors will find articles on that subject no matter what term the author used in the title or abstract.
