We live in an exciting time for ecology.  The ease of access and availability of environmental data has increased exponentially over the past few decades. There are now online databases with ecological data from around the world. These large collaborative datasets can help us advance ecological theory and identify overarching principles that structure ecosystems at a global scale. Below are a few of my favorite open-access databases. You can request data from these websites to test your own questions, or help support these efforts by contributing data!
