This video will provide you with an overview of how to conduct database searches. You may want to search in Academic Search Premier, like the video shows, or select a Biology-specific database. You will also need to figure out which key words will work for your topic -- try to keep it to 2 or 3 main concepts when you conduct your search, such as fracking AND "climate change" AND "United States".
|Use keywords, not long search phrases||
Instead of searching for "What are the human impacts on the vaquita dolphin population?" break down your search into the main keywords:
human impacts, vaquita dolphin, Phocoena sinus, endangered
To get more focused results:
Use quotation marks (" ") to keep phrases together
Use AND to combine different keywords
|"human impacts" AND "phocoena sinus"|
To get broader results:
Use OR to combine similar/associated keywords
("vaquita dolphin" OR "phocoena sinus") AND "human impacts"
|Look for ways to limit your search in the database||You can often limit by type of article (scholarly and peer-reviewed) & year of publication|
|Look for REVIEW articles||Limit your search by review articles, which are often easier to read because they summarize the research that's been done. These are also peer-reviewed sources, so they would count towards your required number of peer-reviewed, scholarly sources.|
