The North American Breeding Bird Survey (1966-present) consists of data on the diversity and abundance of summer bird assemblages at approximately 5000 sites across the continental U.S. and Canada. Sampling began in 1966 and many sites have time-series that are at least 20 years long.MORE
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 Konza Long-term Ecological Research site (LTER) is located on a 3,847 ha tall-grass prairie reserve in Kansas. Konza LTER is divided into experimental watersheds, where each watershed is subjected to a combination of different fire and grazing intensities. Long-term monitoring of small mammal communities has been conducted on a...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

This metadataset describes the effects of biodiversity on response variables of experimental studies published between 1974-2004. Dataset Location: Ecological Archives Methods : Data was extracted from 137 published articles, containing 761 measurments, for analysis within this study to determine the effect of biodiversity loss on variables relevant to agriculture, forestry,...MORE
This dataset summarized the effect of experimentally reducing species richess has on abundance or biomass of the focal group, abundance or biomass of the focal group's primary resource, and/or the depletion of resources by that trophic group. Dataset Location: Ecological Archives Methods: Experimental studies were chosen for their focus and...MORE
