We maintain and regularly update the following databases. Neither is an attempt at a systematic survey of databases–thus the “opportunistic” aspect.
The Opportunistic Database of Biodiversity Databases: An attempt to catalogue the diversity of biodiversity databases, currently with ~400 entries. Looking for specimen databases? Animal tracking data? Traits? Biotic interactions? Range maps? Phylogenies? Images and video? It’s all here!
The Opportunistic Database of Weather Generators: A running list of stochastic weather generators. New but growing!
