Riparian Evapotranspiration (Et) Study (Seon) From The Middle Rio Grande River Bosque, New Mexico (1999-2011): Energy Balance Data, Clifford Dahm, Jim Thibault

Sevilleta LTER Program Data

This study originated with the objective of parameterizing riparian evapotranspiration (ET) in the water budget of the Middle Rio Grande. We hypothesized that flooding and invasions of non-native species would strongly impact ecosystem water use. Our objectives were to measure and compare water use of native (Rio Grande cottonwood, Populus deltoides ssp. wizleni) and non-native (saltcedar, Tamarix chinensis & Russian olive, Eleagnus angustifolia) vegetation and to evaluate how water use is affected by climatic variability resulting in high river flows and flooding as well as drought conditions and deep water tables. Eddy covariance flux towers to measure ET and shallow …

Warming-El Nino-Nitrogen Deposition Experiment (Wenndex): Soil Nitrogen Data From The Sevilleta National Wildlife Refuge, New Mexico (2006 - Present), Scott Collins, William Pockman

Sevilleta LTER Program Data

Humans are creating significant global environmental change, including shifts in climate, increased nitrogen (N) deposition, and the facilitation of species invasions. A multi-factorial field experiment is being performed in an arid grassland within the Sevilleta National Wildlife Refuge (NWR) to simulate increased nighttime temperature, higher N deposition, and heightened El Niño frequency (which increases winter precipitation by an average of 50%). The purpose of the experiment is to better understand the potential effects of environmental drivers on grassland community composition, aboveground net primary production and soil respiration. The focus is on the response of two dominant grasses (Bouteloua gracilis and …

Gunnison's Prairie Dog Relocation Project: Vegetation Cover Data From The Sevilleta National Wildife Refuge, New Mexico (2005-2013), Ana Davidson, David Lightfoot

Sevilleta LTER Program Data

Prairie dogs are keystone species that impact both animals and plants in grassland habitats. They are a food resource for secondary consumers such as badgers, foxes, and raptors. Also, the mounds that they construct are home to many arthropod and reptile species that otherwise might not survive in grasslands. Both Gunnison’s and black-tailed prairie dogs can increase the number of plant species in grasslands and landscape heterogeneity with their ecosystem engineering that creates disturbed patches on the landscape. Gunnison’s prairie dogs, which were native herbivores at the Sevilleta National Wildlife Refuge (NWR) before their populations disappeared, were reintroduced at the …

Hobo Datalogger-Derived Precipitation Data From The Sevilleta National Wildlife Refuge, New Mexico (2008-Present), Douglas I. Moore

Sevilleta LTER Program Data

Precipitation is recognized as the most spatially variable abiotic variable in arid ecosystems such as the Sevilleta National Wildlife Refuge (NWR). Water is also usually the limiting factor in such environments so the accurate measurement of precipitation in both space and time is vital to understanding ecosystem dynamics. In 2008, the acquisition of a number of tipping-bucket rain gauges with Hobo dataloggers permitted the deployment of gauges into an increased number of locations on the Sevilleta NWR. Most dataloggers were installed in the greater Five Points area and primarily placed around the site of the 2003 burn study. A few …


Investigating Host Feeding Strategy As A Determinant Of Insect Gut Microbial Community Profile At The Sevilleta National Wildlife Refuge, New Mexico, Daniel Colman, Cristina Takacs-Vesbach, Eric Toolson Mar 2016

Investigating Host Feeding Strategy As A Determinant Of Insect Gut Microbial Community Profile At The Sevilleta National Wildlife Refuge, New Mexico, Daniel Colman, Cristina Takacs-Vesbach, Eric Toolson

Sevilleta LTER Program Data

Diverse microbial communities live in the gut regions of animals. The precise ecological and evolutionary circumstances that govern relationships between hosts and their gut communities is unclear. In this study, we hypothesize that host feeding strategy shapes the microbial communities within the gut systems of insects. We collected five insect species from the Sevilleta National Wildlife Refuge that exhibited herbivorous, detritovorous and carnivorous diets. Using gut samples from the insects we measured if and how microbial communities are shaped based on any effect host feeding strategy might have. Preliminary analysis of bacterial communities using 16S rDNA sequences has thus far …


Pinon-Juniper Overstory Density, Cover And Biomass Data From Cerro Montosa, Sevilleta National Wildlife Refuge, New Mexico (2006-2009), Esteban Muldavin Mar 2016

Pinon-Juniper Overstory Density, Cover And Biomass Data From Cerro Montosa, Sevilleta National Wildlife Refuge, New Mexico (2006-2009), Esteban Muldavin

Sevilleta LTER Program Data

In 2006, to obtain a measure of pinon and juniper biomass in the Cerro Montosa area, belt transects were superimposed on transects along which understory net primary producitivy (NPP) is sampled. All trees rooted within 5 m to the north of each belt were tagged, although some shorter belts exist on which all trees within 5 m to either the north or south were tagged. The height of each tagged tree was measured, as was the diameter-at root-crown (DRC). Crown diameters both parallel and perpendicular to the belt transect were also measured. Trees were re-measured in 2007, 2008, and 2009.

Livestock Exclosure Study: Aboveground Standing Crop From A Chihuahuan Desert Grassland At The Sevilleta National Wildlife Refuge, New Mexico (2005-2007), Scott Collins

Sevilleta LTER Program Data

Grazing in grasslands creates changes in plant community structure. The magnitude of these changes depends on the productivity and the intensity of grazing. Low productivity grasslands coupled with high grazing intensity may lead to shrub encroachment in some aridland ecosystems. We examined the effects of cattle grazing in arid grassland at the Sevilleta LTER site in central New Mexico USA where cattle were removed in 1973 and an area just north of the Sevilleta LTER where grazing by cattle still occurs. At each site we measured plant species composition and cover in permanent plots in the spring and fall from …

Nitrogen Fertilization Experiment (Nfert): Seasonal Biomass And Seasonal And Annual Npp Data At The Sevilleta National Wildlife Refuge, New Mexico (2004- Present), Scott Collins

Sevilleta LTER Program Data

Begun in spring 2004, this long-term study at the Sevilleta LTER examines how fertilization affects above-ground biomass production (ANPP) in a mixed desert-grassland. Net primary production is a fundamental ecological variable that quantifies rates of carbon consumption and fixation. Estimates of NPP are important in understanding energy flow at a community level as well as spatial and temporal responses to a range of ecological processes. While measures of both below- and above-ground biomass are important in estimating total NPP, this study focuses on above-ground net primary production (ANPP). Above-ground net primary production is the change in plant biomass, including loss …

Sevilleta LTER Program Data

Grasslands are among the most imperiled ecosystems in the world where the loss of native species is a consequence of agriculture and desertification. In North America, 90% of the grassland has been converted to cropland where vast areas are now desertified. North America's most iconic grassland herbivores, bison and prairie dogs, are now extinct throughout most of their historic range. This study measures the standing crop of plant vegetation (perennial and annual combined) for the year on areas occupied and not occupied by Gunnison's prairie dogs on the Sevilleta National Wildlife Refuge (NWR).

Pino Gate Prairie Dog Study At The Sevilleta National Wildlife Refuge, New Mexico: Landscape Plot Lizard Data (2001-2002), Ana Davidson, David Lightfoot

Sevilleta LTER Program Data

Keystone species have large impacts on community and ecosystem properties, and create important ecological interactions with other species. Prairie dogs (Cynomys spp.) and banner-tailed kangaroo rats (Dipodomys spectabilis) are considered keystone species of grassland ecosystems, and create a mosaic of unique habitats on the landscape. These habitats are known to attract a number of animal species, but little is known about how they affect lizard communities. Our research evaluated the keystone roles of prairie dogs and kangaroo rats on lizards at the Sevilleta National Wildlife Refuge in central New Mexico, USA. We evaluated the impacts of these rodents on lizard …

Long-Term Dynamics In Soil Field Available Nitrogen And Potentially Mineralizable Nitrogen In A Chihuahuan Desert Grassland At The Sevilleta National Wildlife Refuge, New Mexico (1989-2014), Carleton White, Douglas I. Moore

Sevilleta LTER Program Data

Associated with a project that was based upon the assumption that nitrogen may limit net primary plant production in desert grasslands, this project began measuring available inorganic soil N and potentially mineralizable N of soils at two desert grassland locations. Both available N and potentially mineralizable N were greatest following a drought period in 1989, declined during wetter periods that followed and remained relatively stable until another extended drought period. After drought in 1995-6, both forms of soil N increased, indicating the potential for greater NPP following drought and lower potential NPP during periods of normal precipitation.
