Competition for scarce Colorado River water resources is nothing new, but the conflicts that prompted the seven basin states to negotiate the 1922 Colorado River Compact have grown considerably fiercer and more complex in recent decades. In 2007, responding to the challenges of increasing demand and sustained drought, the seven basin states and a number of other affected interests agreed to a set of interim guidelines for allocating Colorado River water in the event of shortages. This agreement represents an important evolution in the governance of the Colorado River, suggesting that the many interests in the basin can work together …

Detecting Spatiotemporal Changes Of Corn Developmental Stages In The U.S. Corn Belt Using Modis Wdrvi Data, Toshihiro Sakamoto, Brian D. Wardlow, Anatoly A. Gitelson
Detecting Spatiotemporal Changes Of Corn Developmental Stages In The U.S. Corn Belt Using Modis Wdrvi Data, Toshihiro Sakamoto, Brian D. Wardlow, Anatoly A. Gitelson
School of Natural Resources: Faculty Publications
The dates of crop developmental stages are important variables for many applications including assessment of the impact of abnormal weather on crop yield. Time-series 250-m vegetation-index (VI) data acquired from the Moderate Resolution Imaging Spectroradiometer (MODIS) provide valuable information for monitoring the spatiotemporal changes of corn growth across large geographic areas. The goal of this study is to evaluate the performance of a new crop phenology detection method, namely, two-step filtering (TSF), for revealing the spatiotemporal pattern of specific corn developmental stages (early vegetative: V2.5; silking: R1; dent: R5; mature: R6) over an eight-year period (2001–2008) across Iowa, Illinois, and …
An Analysis Of A Management Case: Green Hill Beach Development Of The Rhode Island Coastal Zone, John R. Braddon
An Analysis Of A Management Case: Green Hill Beach Development Of The Rhode Island Coastal Zone, John R. Braddon
Marine Affairs Theses and Major Papers
One of the most valuable and misused assets possessed by the United States is the rich and highly varied coastal zone. The genesis of much of our material wealth and the basis for success of the early colonies has been our national fascination with the sea. As our industry and population have expanded, the coastal zone has been neglected seriously to the detriment of both current and future generations of Americans. Abuse of the coastal zone stems from employing it as a dumping ground, using the rivers flowing into it for effluent disposal and haphazard, poorly planned development. Since the …

Camera Study For Mammalian Carnivore Presence Across Seasons In Montana De Oro State Park, San Luis Obispo County, Ca, Samuel R. Young
Camera Study For Mammalian Carnivore Presence Across Seasons In Montana De Oro State Park, San Luis Obispo County, Ca, Samuel R. Young
Natural Resources Management and Environmental Sciences
Montana de Oro (MDO) is one of the largest state parks in California. Little is known however about its wildlife or their habits. Large predators such as mountain lion (Puma concolor) and black bear (Ursus americanus), and non–native species such as red fox (Vulpes vulpes) and feral pig (Sus scropha) are of management concern because of their potentially dramatic ecological roles. Cameras were deployed at 5 sites along the Coon Creek hiking trail in spring (May 3–June 7), summer (July 15–August 19), and fall (October 10–November 23) sessions with the goal of …
Effects Of Species, Water, And Nitrogen On Competition Among Three Prairie Grasses, Jerry L. Weatherford, Randall W. Myster
Effects Of Species, Water, And Nitrogen On Competition Among Three Prairie Grasses, Jerry L. Weatherford, Randall W. Myster
The Prairie Naturalist
We conducted an experiment to investigate effects of species, water (W), and nitrogen (N) on competition among little bluestem (Schizachyrium scoparium), sideoats grama (Bouteloua curtipendula), and indiangrass (Sorghastrum nutans). All biomass parameters and the root:shoot ratio of little bluestem were reduced by the presence off 1 of 2 other species, and its shoot biomass and total biomass were both increased by addition of N. Root and shoot biomass of sideoats grama were reduced by the presence of indiangrass and its total biomass was reduced by the presence of itself, whereas its shoot biomass was increased by addition of W at …
Assessing The Role Of Conspecific Attraction In Habitat Restoration For Henslow’S Sparrows In Iowa, Jennifer A. Vogel, Rolf R. Koford, David L. Otis
Assessing The Role Of Conspecific Attraction In Habitat Restoration For Henslow’S Sparrows In Iowa, Jennifer A. Vogel, Rolf R. Koford, David L. Otis
The Prairie Naturalist
The presence of conspecific individuals may provide important cues about habitat quality for territorial songbirds. We tested the ability of a conspecific song playback system to attract Henslow’s sparrows to previously unoccupied restored habitat. We successfully attracted Heslow’s sparrows to 3 of 7 treatment plots using conspecific song playbacks and we found no Henslow’s sparrows in control plots. The addition of social cues using playback systems in restored grassland habitats may aid conservation efforts of Henslow’s sparrows to available habitat.
Notes: River Otters Use Agricultural Field Along The Turtle Riveri In Eastern North Dakota As Crossover And Latrine Area, Maggie D. Triska, Steven C. Loughry, Thomas L. Sergass
Notes: River Otters Use Agricultural Field Along The Turtle Riveri In Eastern North Dakota As Crossover And Latrine Area, Maggie D. Triska, Steven C. Loughry, Thomas L. Sergass
The Prairie Naturalist
Recently, the Nearctic river otter (Lontra canadensis) has been re-colonizing portions of eastern North Dakota. The landscape in eastern North Dakota is dominated by agricultural fields and pastures, habitats which have received little research attention related to otter habitat use. During 2008, we searched shorelines to detect otter latrines, which is a common method for determining otter presence. Generally, latrines are locations along bodies of water where otters deposit scats, urine, and glandular secretions for olfactory communication, and groom, wrestle, and play, which may mat vegetation. In the northeastern United States, inland riverine system studies have shown latrines …

Calodium Hepaticum In White-Tailed Jackrabbits In South Dakota, Dustin J. Schaible, Charles D. Dieter, Regg D. Neiger, Michael B. Hildreth
The Prairie Naturalist
White-tailed jackrabbits (Lepus townsendii) are common on the prairie, and an important species in prairie food webs (Lim 1987). Although it has been suggested that jackrabbits have cyclic populations (Donoho 1972, Gross et al. 1974, Anderson and Shumar 1986), there is concern that a general downward trend exists in populations in the Northern Great Plains (Feldhamer et al. 2003). Disease incidence in white-tailed jackrabbits is poorly known (Feldhamer et al. 2003), but may be an important factor in population changes. Tularemia, a disease caused by bacteria (Francisella tularensis), occurs throughout the Northern Hemisphere and can affect many mammals including hares, …
Resource Selection By Elk At Two Spatial Scales In The Black Hills, South Dakota, Mark A. Rumble, R. Scott Gamo
Resource Selection By Elk At Two Spatial Scales In The Black Hills, South Dakota, Mark A. Rumble, R. Scott Gamo
The Prairie Naturalist
Understanding resource selection by elk (Cervus elaphus) at multiple spatial scales may provide information that will help resolve the increasing number of resource conflicts involving elk. We quantified vegetation at 412 sites where the precise location of elk was known by direct observation and 509 random sites in the Black Hills of South Dakota during 1998– 2001. We obtained stand level variables from geographic information system coverages for a 250 m buffer around elk and random sites. We used classification and regression trees to simultaneously evaluate environmental thresholds of resources selected by feeding and bedded elk at the site and …
Multiple Bats Entangled On Cactus, Jon C. Pigage, Richard L. Bunn
Multiple Bats Entangled On Cactus, Jon C. Pigage, Richard L. Bunn
The Prairie Naturalist
Accidental deaths of bats by entanglement on plants and barbed wire are common (McNicholl 1988, Norquay et al. 2010). It has been hypothesized these incidents involve miscalculations by bats on how close they fly to plants or barbed wire or when chasing insects highly concentrated around vegetation (Norquay et al. 2010). Once the bats hit the plants or barbed wire, they become entangled and or impaled while struggling to free themselves. The earliest reports involved little brown bats (Myotis lucifugus) and unidentified bats entangled on burdock, Arctium sp. (Lyon 1925, Little 1925). Additional reports of bats becoming entangled in plants …
First Record Of The Least Weasel In The Black Hills Of South Dakota, Tim R. Mullican
First Record Of The Least Weasel In The Black Hills Of South Dakota, Tim R. Mullican
The Prairie Naturalist
The least weasel (Mustela nivalis) is a circumboreal species, occurring in North America from Alaska to the Appalachian Mountains (Jones et al. 1983). In the Great Plains, the least weasel recently expanded its range southward through Nebraska (Benedict et al. 2000) and Kansas (Choate et al. 1979, Bailey and Terman 1986) into Oklahoma (Clark and Clark 1988). Also, in recent decades, the least weasel has expanded from eastern and central Nebraska into western Nebraska (Benedict et al. 2000). In South Dakota, least weasels have been previously reported from the eastern 3/4 of the state (Jones et al. 1983, Higgins et …
Phragmites Australis In South Dakota: Historical Distribution And Environment, Carol A. Johnston, Kayla L. Miller
Phragmites Australis In South Dakota: Historical Distribution And Environment, Carol A. Johnston, Kayla L. Miller
The Prairie Naturalist
Common reed, Phragmites australis, has long been a component of Northern Plains wetlands, but impending invasion by the non-native P. australis haplotype M may displace native haplotypes in the future. To increase understanding of historical Phragmites occurrence, we developed a geographic information system (GIS) protocol to improve the georeferencing of specimens from South Dakota herbaria, and mapped the distribution of Phragmites relative to geology, physiographic regions, and water bodies. There were 91 Phragmites herbarium specimens from South Dakota and adjacent Wyoming. Phragmites collections occurred in nearly all physiographic regions of the state, with concentrations occurring in the Prairie Coteau of …
Crustaceous Zooplankton Transfer Between A Floodplain Wetland And The Missouri River, Shannon J. Fisher
Crustaceous Zooplankton Transfer Between A Floodplain Wetland And The Missouri River, Shannon J. Fisher
The Prairie Naturalist
Floodplain interactions are a critical riverine ecosystem function, including zooplankton transfer. Floodplain alternations have had an assumed impact on zooplankton productivity. I assessed floodplain wetland and main channel densities of crustaceous zooplankton, alluding to organism transfer in the Missouri River, North Dakota. Significant t-test differences (P < 0.05) were present between backwater and channel habitat zooplankton densities in 83, 75, 83, and 50% of the sample periods for cyclopoid copepods, copepod nauplii, Daphnia spp., and Bosmina spp. respectively, suggesting the presence of uncoupled zooplankton dynamics during portions of each annual cycle. Two relationships with increased flows were found, including a biologically significant decrease (P = 0.09) of backwater copepod nauplii numbers and a significant increase (P = 0.02) in the channel density of Daphnia spp. During the highest flow periods, fewer significant differences in zooplankton densities were present between the backwater and channel habitats, indicating moderate homogenization.
Logistic Curves, Extraction Costs And The Effective Size Of Oil Resources, Robert J. Brecha
Logistic Curves, Extraction Costs And The Effective Size Of Oil Resources, Robert J. Brecha
Physics Faculty Publications
The size of potential fossil fuel resources is an issue of perennial interest and controversy. Fundamentally, there appears to be a conflict in interpretation of available data for both past and future extraction histories. As fossil-fuel prices rose dramatically over the past several years, the question of resources once again became acute. In this paper we concentrate on conventional and non-conventional oil resources and make four main points, with the overarching theme that one can determine an effective oil resource that represents significantly less availability for consumption than usually posited by tallying resources in place.
First, looking at oil production …
