This web site hosts time series data sets from hundreds of independent projects aiming to understand the patterns and dynamics of bird populations across the western hemisphere. In particular, eBird connects remote-sensed data of landscape variables and human population to species ocurrence. Each data set consists of observational data, the...MORE

A large compilation of empirical data on how traits respond to environmental drivers. Dataset Location: The dataset is available both online where selected data for individual populations can be downloaded one at a time and as a Data Paper in Ecological Archives providing access to the entire dataset in one...MORE
Via NEON's overview page: Data will be collected from 106 sites (60 terrestrial, 36 aquatic and 10 aquatic experimental) across the U.S. (including Alaska, Hawaii and Puerto Rico) using instrument measurements and field sampling. NEON will combine site-based data with remotely sensed data and existing continental-scale data sets (e.g. satellite...MORE
This website and database hosts records of fossil pollen, charcoal, and mammal assemblages, as well as plant macrofossils, largely from North America, but also globally, throughout the Pleiocene-Quaternary (and Anthropocene). Also included are chronological controls that allow the use of the records through time from the last 5 million years...MORE
