Groundwater Flow Model And Particle Track Analysis For Selecting Water Quality Monitoring Well Sites, And Soil Sampling Profiles, Michael A. Nwachukwu, Huan Feng, Duke Ophori Sep 2010

Groundwater Flow Model And Particle Track Analysis For Selecting Water Quality Monitoring Well Sites, And Soil Sampling Profiles, Michael A. Nwachukwu, Huan Feng, Duke Ophori

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Researchers often use only surface drainage (imperical method) as a tradition to locate sites for installation of water quality monitoring wells, and soil sampling profile for pollution studies in urban areas. They neglect that structural development may have altered the natural surface drainage. This paper demonstrates an advanced method; combining surface imperical method with a three-dimensional groundwater flow model and particle track analysis. This was performed using transient MODFLOW and MODPATH codes, as a first step in a pollution study of Owerri urban areas. Result was more reliable, showing diverging flows at Orji and Nekede auto-mechanic villages (MVs) due to …

Core Research Site Web Quadrat Data For The Net Primary Production Study At The Sevilleta National Wildlife Refuge, New Mexico (1999-Present), Esteban Muldavin

Sevilleta LTER Program Data

This dataset is part of a long-term study at the Sevilleta LTER measuring net primary production (NPP) across four distinct ecosystems: creosote-dominant shrubland (Site C, est. winter 1999), black grama-dominant grassland (Site G, est. winter 1999), blue grama-dominant grassland (Site B, est. winter 2002), and pinon-juniper woodland (Site P, est. winter 2003). 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. Above-ground net primary production is the …

Monsoon Rainfall Manipulation Experiment (Mrme) Soil Temperature Data From The Sevilleta National Wildlife Refuge, New Mexico (7/2007-8/2009), Scott Collins Sep 2010

Monsoon Rainfall Manipulation Experiment (Mrme) Soil Temperature Data From The Sevilleta National Wildlife Refuge, New Mexico (7/2007-8/2009), Scott Collins

Sevilleta LTER Program Data

The Monsoon Rainfall Manipulation Experiment (MRME) is to understand changes in ecosystem structure and function of a semiarid grassland caused by increased precipitation variability, which alters the pulses of soil moisture that drive primary productivity, community composition, and ecosystem functioning. The overarching hypothesis being tested is that changes in event size and variability will alter grassland productivity, ecosystem processes, and plant community dynamics. In particular, we predict that many small events will increase soil CO2 effluxes by stimulating microbial processes but not plant growth, whereas a small number of large events will increase aboveground NPP and soil respiration by providing …

Sevilleta LTER Program Data

The U.S. Fish and Wildlife's plan to apply a prescribed burn to a large portion of Mckenzie Flats was deemed an opportunity to study the effects of fire on the vegetation at the boundary between shrubland and grassland. This study actually was undertaken on an area that had prescribed fire applied to 8 of 16 (300 m x 300 m) plots 10 years before in 1993. This previous study had also examined the effects of fencing to exclude the indigenous prong-horn antelope. In the 2003 study the prescribed fire was applied to the northeastern half of the 16 plots while …

Population Ecology Of Banner-Tailed Kangaroo Rats (Dipodomys Spectabilis) In A Chihuahuan Desert Grassland At The Sevilleta National Wildlife Refuge, New Mexico (2005-2009), Andrew Edelman

Sevilleta LTER Program Data

From March 2005-Februaury 2009, a population of banner-tailed kangaroo rats was monitored using mark-recapture methods. All active kangaroo rat mounds on the 18-ha Nunn Flats site were trapped monthly. All captured individuals were marked and reproductive status and mass were recorded. From February to July 2008 a subset of adult females received supplemental food. This dataset was collected to observe the survivorship, reproduction, and dispersal of banner-tailed kangaroo rats in response to changes in resources and density. Both observational and experimental methods were used to observe how ecological constraints affected juvenile dispersal.

Pino Gate Prairie Dog Study At The Sevilleta National Wildlife Refuge, New Mexico: Mound-Scale Lizard Data (2000-2002), 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 …

Soil Surface Dynamics In The Chihuahuan Desert At The Sevilleta National Wildlife Refuge, New Mexico (1994-2013), Carleton White Sep 2010

Soil Surface Dynamics In The Chihuahuan Desert At The Sevilleta National Wildlife Refuge, New Mexico (1994-2013), Carleton White

Sevilleta LTER Program Data

Observations of the soil surface on the Sevilleta National Wildlife Refuge indicate that the surface is very dynamic. During collections of decomposition bags it has been noted that the bags are frequently resting on pedestals of soil, often 2-3cm above the surrounding surface. This study will attempt to measure the dynamics of the soil surface using a specially designed soil bridge. The soil bridge will allow for repeated measurements of the relative height of the soil surface at several sites on the Sevilleta. These measurements will be used to assess the impact of the changing soil surface on nutrient cycling.

Temporal Dynamics Of Soil Carbon And Nitrogen Resources Within A Grassland-Creosote Ecotone At The Sevilleta National Wildlife Refuge, New Mexico (1992-1994), Carleton White, Thomas L. Kieft Sep 2010

Temporal Dynamics Of Soil Carbon And Nitrogen Resources Within A Grassland-Creosote Ecotone At The Sevilleta National Wildlife Refuge, New Mexico (1992-1994), Carleton White, Thomas L. Kieft

Sevilleta LTER Program Data

Plant communities across large portions of the southwestern United States have shifted from grassland to desert shrubland. Studies have demonstrated that soil nutrient resources become spatially more heterogeneous and are redistributed into islands of fertility with this shift in vegetation. This research addressed the additional question of whether soil resources become more temporally heterogeneous along a grassland-shrubland ecotome. Within adjacent grassland and creosotebush sites, soil profiles were described at 3 pits and samples collected for description of nutrient resources within the profile. Relative cover of plant species and bare soil were determined within each site by line transects. The top …

Sevilleta LTER Program Data

Disturbance from fire can affect the abundance and distribution of shrubs and grasses in arid ecosystems. In particular, fire may increase grass and forb production while hindering shrub encroachment. Therefore, prescribed fires are a common management tool for maintaining grassland habitats in the southwest. However, Bouteloua eriopoda (black grama), a dominant species in Chihuahuan Desert grassland, is highly susceptible to fire resulting in death followed by slow recovery rates. A prescribed fire on the Sevilleta National Wildlife refuge in central New Mexico in 2003 provided the opportunity to study the effects of infrequent fires on vegetation in this region. This …
