The Portal Project is a long-term ecological study that has been monitoring small mammal community responses to climate and experimental manipulation of dominant rodent species since 1977 in southeastern Arizona. Ecological Level: Community Biome: Desert Location: Southeastern Arizona (Lat/Long) Spatial Scale of data: Each plot is .25 ha. There are...MORE
The FIADB contains community information for sites throughout forested lands of the US and its territories. There are three stages of sampling, which affects the type of data available for any given site: Phase 1 consists of remote sensing for stratification and identification of forested land. Phase 2 [Forest Inventory...MORE
Over 22 years, Alwyn H. Gentry collected data from 226 sites on six continents. Gentry and his collaborators collected all plants with stem diameters equal to or exceeding 2.5 cm diameter at breast height (dbh) along ten 2 x 50 m transects, totaling 0.1 hectare at each site. Ecological Level:...MORE
