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
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
This dataset describes long-term (1977-2002) experimental manipulations of ant, plant and rodent species in a desert ecosystem, among other alterations to the system. Data Location: Ecological Archives Site Location: Chihuahuan Desert, near Portal, Arizona (31 o 56' 20.29" N, 109 o 4' 47.44" W) Sites Georeferenced: Yes (not part of...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
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
Database including information on distribution, taxonomy, and synonyms for birds. Data location: http://avibase.bsc-eoc.org/ Uses: Of particular interest is the tool for comparing two differt checklists. This provides information to help combine datasets that are based on different taxonomies, and the determine what has changed from one version of the taxonomy...MORE
The USGS Gap Analysis Program (GAP) is delineating species range and predicted distribution maps for more than 2,000 species that occur within the continental US as well as Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands (we will make these maps and datasets available as they are completed). Our...MORE
The USGS Gap Analysis Program (GAP) PAD-US is the national inventory of U.S. terrestrial and marine protected areas that are dedicated to the preservation of biological diversity and to other natural, recreation and cultural uses, managed for these purposes through legal or other effective means. Lands in PAD-US are mainly...MORE
