LTER Network Annual Net Primary Productivity (ANPP)

Title: Variation among biomes in temporal dynamics of aboveground primary production
Investigators: Alan K. Knapp, Melinda D. Smith
Abstract:Annual net primary production (ANPP) and annual precipitation data from 11 Long Term Ecological Research (LTER) sites across North America. Data were compiled for analyses summarized in a study published in Science (2000, 291:481-484). These data were obtained online or received directly form site investigators. For those sites with multiple communities sampled, only a single, representative community type was selected from each site. Each LTER site included in this dataset used unique methods for estimating ANPP (see individual web pages at http://lternet.edu/sites/ for details). Click here to the original Science article online
