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 Short-Grass Steppe (SGS) Long-term Ecological Research site (LTER) is a long-term census of small mammals conducted twice yearly at six separate trapping locations distributed across two different habitats, grassland and shrubland, in Colorado USA. Ecological Level: Community Habitat: Grassland and Shrubland Location: Colorado (Lat/Long) Spatial Scale of data: 6...MORE
The Sevilleta (SEV) Long-term Ecological Research site (LTER) is located on a 100,000 ha wildlife refuge in central new Mexico where long-term monitoring of small mammal communities has been conducted since 1989. Small mammal monitoring is conducted 2-3 times yearly in multiple habitats distributed across the refuge. Ecological Level: Community...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
Powdermill Nature Reserve monitored small mammal populations from 1979-1999.MORE
A global species-level data set of key life-history, ecological and geographical traits of all known extant and recently extinct mammals compiled from the literature. It also includes spatial databases of mammalian geographic ranges and global climatic and anthropogenic variables. Ecological Level: Species Biome: All Location: Global Observational/Experimental: Observational Dataset Location:...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
Please see details in the cited publication. In addition to the presence absence data, there are also photos of each subplot from 2005 onward. Nelis, L.C. and J.T. Wootton, Treatment-based Markov chain models clarify mechanisms of invasion in an invaded grassland community. Proceedings of the Royal Society Biological Sciences Series...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
Assessing the direct and indirect consequences of nonrandom species removal within guilds of strongly interacting species, such as large mammalian herbivores, is an important goal in basic and applied ecology. The ecological impacts of such perturbations are often contingent on abiotic conditions, which have hindered efforts to generalize the results...MORE
