Biodiversity informatics is the creation, integration, analysis, and understanding of information about biological diversity. The emphasis is on primary data of historical and current species occurrence points, which serve as inputs for predictive modeling and ecological forecasting of the likely effects of local and global change. Applications have included predicting the spread of invasive species and disease agents, and changes in species distributions due to climate change. I will share sources of big data as it relates to biodiversity informatics and some examples of applications of these data.
