Seasonal Resource Selection And Habitat Treatment Use By A Fringe Population Of Greater Sage-Grouse, Rhett Boswell
Seasonal Resource Selection And Habitat Treatment Use By A Fringe Population Of Greater Sage-Grouse, Rhett Boswell
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Movement and habitat selection by Greater Sage-grouse (Centrocercus uropasianus) is of great interest to wildlife managers tasked with applying conservation measures for this iconic western species. Current technology has created small and lightweight GPS (Global Positioning Systems) transmitters that can be attached to sage-grouse. Using GIS software and statistical programs such as Program R, land managers can analyze GPS location data to assess how sage-grouse are geospatially interacting with their habitats. Within the Panguitch Sage-Grouse Management Area (SGMA) thousands of acres of land have been restored or manipulated to enhance sage-grouse habitat; this usually involves removal of pinyon pine …
Weed Establishment And Persistence After Water Pipeline Installation And Reclamation In The Mixed Grass Prairie Of Western North Dakota, Erin K. Espeland, Lora B. Perkins
Weed Establishment And Persistence After Water Pipeline Installation And Reclamation In The Mixed Grass Prairie Of Western North Dakota, Erin K. Espeland, Lora B. Perkins
Natural Resource Management Faculty Publications
Weeds in reclamations interfere with success by: 1) competing with desirable species seeded during revegetation; 2) preventing recolonization of reclamations by native species; and 3) reducing the integrity of landscapes by expanding from reclamations into adjacent, intact areas. In the Bakken oilfield of western North Dakota, dispersed reclamation activity and increased traffic may provide many opportunities for weeds to spread. To determine the potential for disturbance and reclamation to increase resident weed populations and introduce new weed species, we tracked twenty-one weed (non-native/ruderal/invasive) species over a four-year period after the installation of a 1.8 km livestock water pipeline and subsequent …
Community Management And Governance Of Comatsa-Sud New Protected Area (Ambalamanasy Ii Commune), Allison Tennant
Community Management And Governance Of Comatsa-Sud New Protected Area (Ambalamanasy Ii Commune), Allison Tennant
Independent Study Project (ISP) Collection
Community-based natural resource management is an increasingly more popular choice for governments to delegate power back to local communities to conserve the resources they rely on. In Madagascar, where much of the rural population provides for their livelihoods by using natural resources, this governance structure, in cooperation with delegated manager for assistance, presents an opportunity for economic development in cooperation with conservation efforts. This paper aims to better understand the role of community, NGO, and governmental actors in creating and executing community management structures. Through Participatory Rural Analysis and structured and semi-structured interviews, it explores what management transfers look like …
Mapping The Ecology Of Information: Hierarchical Habitat Selection By Nebraska Pheasant Hunters, Lyndsie Wszola
Mapping The Ecology Of Information: Hierarchical Habitat Selection By Nebraska Pheasant Hunters, Lyndsie Wszola
School of Natural Resources: Dissertations, Theses, and Student Research
Hunting regulations are assumed to moderate the effects of hunting consistently across a game population. A growing body of evidence suggests that hunter effort varies temporally and spatially, and that variation in effort at multiple spatial scales can affect game populations in unexpected ways. We set out to determine the causes of variation in hunting effort among ring-necked pheasant (Phasianus colchicus) hunters at four spatial scales: among regions within the state of Nebraska, among sites within a given region, among access points at a given site, and among habitat patches within a site. At each scale, pheasant hunters used direct …

Strategies For Environmental Education For Youths And Adults, Chumbe Island Coral Park, Zanzibar, Samantha Pfeffer
Independent Study Project (ISP) Collection
Chumbe Island Coral Park (CHICOP) is a privately-owned business that strives to follow the best principles of ecotourism, conservation, and environmental education. Their environmental education initiative is award-winning and has affected thousands of students and community members in Zanzibar. This study looked at the environmental education techniques that CHICOP already has in place by observing two pre-visits, three island-visits and one-post visit, and determined where there was a need for enhanced and new techniques for teaching about the environment. Evidence of climate change on Chumbe Island was also recorded to aid in the educational tools and to create a database …
Spatial And Temporal Variation In Mangrove Distribution (1950-2014) In Tampa, Florida Usa, Carolyn Cheatham Rhodes
Spatial And Temporal Variation In Mangrove Distribution (1950-2014) In Tampa, Florida Usa, Carolyn Cheatham Rhodes
USF Tampa Graduate Theses and Dissertations
I carried out an observational study of historic high resolution aerial imagery spanning six decades (1950-2014) to identify recent and historic spatial extent of mangrove forests, within the municipal boundaries of the City of Tampa, Florida USA. My objectives were to map mangrove distribution and spatial extent and any change or patterns of change discernable. I observed variable patterns of change and rates of expansion varied between sites spatially as well as within sites between time intervals. I found notable changes in mangrove extent in the Tampa from historic and modern aerial imagery for the ~64-year period between 1950 and …
Heterogeneity Of Avian Breeding Habitat On Grazing Lands Of The Northern Great Plains, Maggi S. Sliwinski
Heterogeneity Of Avian Breeding Habitat On Grazing Lands Of The Northern Great Plains, Maggi S. Sliwinski
School of Natural Resources: Dissertations, Theses, and Student Research
Native rangelands in the Great Plains are largely privately owned and used for beef production. Vegetation heterogeneity is important for maintaining biodiversity, but private land may be more homogenous than desired. My research had two components: 1) to examine whether a variety of grazing strategies created vegetation heterogeneity in a large, intact rangeland, and 2) to understand beef producers’ attitudes about vegetation heterogeneity.
First, I sampled vegetation structure, composition, and bird abundance at multiple plots on eleven management units in Cherry County, Nebraska. Units were managed with commonly used grazing strategies (e.g., short-duration grazing and season-long continuous grazing). I examined …
Short-Term Effects Of Nutrients On A Barrier Island Grassland Community, Ashley Moulton
Short-Term Effects Of Nutrients On A Barrier Island Grassland Community, Ashley Moulton
Theses and Dissertations
Increased nutrient availability globally has the potential to affect community functional composition of plants in nutrient limited environments, such as coastal grassland systems. Stability of these systems are threatened worldwide by urbanization, as well as effects of sea level rise and increased frequency and intensity of storms, and atmospheric N deposition, associated with climate change. Annual net primary productivity (ANPP), species composition, and functional traits (community weighted specific leaf area (CWSLA), leaf area index (LAI), growth form and photosynthetic pathway) were measured across four treatments to assess multiple resource limitation of nitrogen (N) and phosphorus (P) and functional community response …
An Integrated Evaluation Of The Conservation Reserve Enhancement Program In South Dakota, Jarrett D. Pfrimmer
An Integrated Evaluation Of The Conservation Reserve Enhancement Program In South Dakota, Jarrett D. Pfrimmer
Electronic Theses and Dissertations
Grassland restoration efforts in North America typically share the goal of improving ecological conditions for wildlife; however, it is unclear in many cases if goals are met. The South Dakota Conservation Reserve Enhancement Program (CREP) was initiated to alleviate agriculturally-related environmental degradation by converting 40,469 hectares of eligible cropland and marginal pastureland to perennial vegetation. The program aims to provide habitat for obligate grassland breeding songbirds, while producing an additional 285,000 pheasants and 60,000 ducks annually. As part of a collaborative comprehensive evaluation effort, my research assessed the response of grassland-dependent breeding birds to CREP implementation at varying spatial scales …

Electronic Theses and Dissertations
From 2015-2017, we evaluated a newly established bighorn sheep (Ovis canadensis) herd in the Deadwood Region of the Black Hills, South Dakota. Our objectives were to 1a) determine annual survival rates, 1b) determine cause-specific mortality, 1c) estimate population size, 2a) assess genetic diversity, 2b) assess disease prevalence, 3) evaluate movement patterns post-release, 4a) evaluate 3rd-order habitat selection, and 4b) estimate herbaceous biomass at foraging sites post-release of translocated bighorn sheep. In February 2015, we captured and translocated 26 bighorn sheep from the Luscar Mine near Hinton, Alberta, Canada to the Deadwood Region of the Black Hills, South Dakota. Overall annual …
An Evaluation Of Nitrogen Supplementation And Processed Soy Fractions On The Performance Of Cultured Fishes, Brandon M. White
An Evaluation Of Nitrogen Supplementation And Processed Soy Fractions On The Performance Of Cultured Fishes, Brandon M. White
Electronic Theses and Dissertations
World population growth has resulted in an increased demand for a sustainable food supply. This rapid growth coupled with an increased per capita consumption of seafood, has resulted in many of the world’s marine fisheries being over-exploited in an effort to meet the global demand for seafood. Aquaculture has attempted to fill the supply and demand gap created by the dwindling supply of fish in the world’s oceans. Fishmeal (FM) has traditionally been the primary protein ingredient in aquafeeds fed to farm-raised fish, however its unstable supply and increasing price have driven researchers to identify alternative protein sources. Soybean meal …
Evaluation Of Gamebird Use And Thermal Characteristics Of Alfalfa And Perennial Grasses In Eastern South Dakota, Neal P. Martorelli
Evaluation Of Gamebird Use And Thermal Characteristics Of Alfalfa And Perennial Grasses In Eastern South Dakota, Neal P. Martorelli
Electronic Theses and Dissertations
The northern Great Plains provide critical breeding habitat for waterfowl and gamebirds in the United States. Peak commodity prices in the late 2000s resulted in increased agricultural production and large-scale conversions of grassland habitat to monoculture row crops. However, recent declines in commodity prices have created a renewed interest for private landowners to diversify crops and enroll in government subsidized conservation programs that convert idle grassland and unproductive cropland to wildlife friendly perennial grassland plantings. Exploring alternative grassland restoration techniques can improve the efficiency of management practices to benefit future wildlife habitat and productivity on both public and private lands. …
Mountain Lion (Puma Concolor) Population Characteristics And Resource Selection In The North Dakota Badlands, Randy D. Johnson
Mountain Lion (Puma Concolor) Population Characteristics And Resource Selection In The North Dakota Badlands, Randy D. Johnson
Electronic Theses and Dissertations
Mountain lions (Puma concolor) have significant ecological impacts on the ecosystems they inhabit, leading to both biological and social ramifications. Yet, due to the relatively recent natural recolonization by mountain lions of the Little Missouri Badlands Region of western North Dakota, detailed data regarding many aspects of this population have been lacking. Therefore, we studied mountain lions occupying the Badlands Region to improve our understanding of mountain lion population ecology, resource selection, and occurrence in North Dakota. Our objectives were to: 1) improve the accuracy of home range size, subadult movement, and survival estimates of mountain lions in …
Characterization Of Ecological Water Stress In The U.S. Great Lakes Region Using A Geospatial Modeling Approach, Sara Alian
Dissertations, Master's Theses and Master's Reports
Anthropocentric water resources management affects aquatic habitats by changing streamflow regime. Understanding the impacts of water withdrawal from different sources and consumption by various economic sectors at different spatial and temporal scales is key to characterizing ecologically harmful streamflow disturbances. To this end, we developed a generic, integrative framework to characterize catchment scale water stress at annual and monthly time scales. The framework accounts for spatially cumulative consumptive and non-consumptive use impacts and associated changes in flow due to depletion and return flow along the stream network. Application of the framework to the U.S. Great Lakes Region indicates that a …
Response Of Amphibian And Invertebrate Communities To Wetland Mitigation In The Greater Yellowstone Ecosystem, Leah K. Swartz
Response Of Amphibian And Invertebrate Communities To Wetland Mitigation In The Greater Yellowstone Ecosystem, Leah K. Swartz
Graduate Student Theses, Dissertations, & Professional Papers
Wetlands play a critical role in supporting freshwater biodiversity and ecosystem services, but human activities have resulted in large-scale loss and degradation of these habitats across the globe. To offset the decline of wetland area, mitigation wetlands are now frequently constructed, but their ability to replace the functions of natural habitats, including providing habitat for native fauna, remains uncertain. A recent highway reconstruction project in northwestern Wyoming caused impacts to and the destruction of multiple natural wetlands. To mitigate this loss, new wetlands were constructed along the highway corridor. To evaluate the performance of these created wetlands relative to reference …
A Statewide Assessment Of Drivers Influencing Biotic Integrity In Perennial, Wadeable Prairie Streams Of South Dakota, Lyntausha Kuehl
A Statewide Assessment Of Drivers Influencing Biotic Integrity In Perennial, Wadeable Prairie Streams Of South Dakota, Lyntausha Kuehl
Electronic Theses and Dissertations
Biological assessments are used to evaluate the biotic integrity of a system. Great Plains prairie streams are harsh environments due to variable climate, topography, vegetation, and human development. This presents a challenge to water resource managers who must detect impairment and determine causation. The objectives of this study were: 1) to develop a macroinvertebrate Index of Biotic Integrity (IBI) for the Northwestern Great Plains (NWGP) and compare it to an existing Northern Glaciated Plains (NGP) IBI, and 2) to identify and evaluate statewide abiotic drivers of biotic integrity. The IBIs were hypothesized to differ regionally, as were abiotic drivers explaining …
Human Dimensions Of Habitat Loss In The Plains And Prairie Potholes Ecoregion, Lily A. Sweikert
Human Dimensions Of Habitat Loss In The Plains And Prairie Potholes Ecoregion, Lily A. Sweikert
Electronic Theses and Dissertations
The Plains and Prairie Potholes Ecoregion (PPPE), is located in the north-central contiguous United States and is one of the most imperiled grassland regions in the world. Most of the region is privately owned and used for the production of agricultural commodities. In addition to its direct benefits to humanity, the PPPE provides multiple ecosystem services including, soil and water quality improvements, carbon sequestration, weather amelioration, and wildlife habitat. Recent increases in expansion of row crop agriculture concerns conservation practitioners about the long-term integrity of the PPPE. Conservation practitioners are looking to improve their private landowner conservation initiatives in the …
Biotic Integrity In The Northwestern Great Plains And Mechanisms Regulating Stream Condition In South Dakota, Chad Kaiser
Biotic Integrity In The Northwestern Great Plains And Mechanisms Regulating Stream Condition In South Dakota, Chad Kaiser
Electronic Theses and Dissertations
Anthropogenic disturbance of streams can alter biotic integrity in various ways. Some degradation is easy to classify and monitor, others such as habitat impairment may be less easy to quantify. The Index of Biotic Integrity (IBI) is a unique method of assessing the aquatic health of an ecosystem. Beginning in 2010 the South Dakota Department of Environment and Natural Resources (SD DENR) began implementing biological monitoring on wadeable streams by developing an IBI for the Northern Glaciated Plains ecoregion in eastern SD (Krause et al. 2013). Prior to this survey the condition of the majority of SD’s streams was unknown. …
Regeneration Responses To Management For Old-Growth Characteristics In Northern Hardwood-Conifer Forests, Aviva Joy Gottesman
Regeneration Responses To Management For Old-Growth Characteristics In Northern Hardwood-Conifer Forests, Aviva Joy Gottesman
Graduate College Dissertations and Theses
Silviculture practices interact with multiple sources of variability to influence regeneration trends in northern hardwood forests. There is uncertainty whether low-intensity selection harvesting techniques will result in desirable tree regeneration. Our research is part of a long-term study that tests the hypothesis that a silvicultural approach called "structural complexity enhancement" (SCE) can promote accelerated development of late-successional forest structure and functions. Our objective is to understand the regeneration dynamics following three uneven-aged forestry treatments modified to increase postharvest structural retention: single-tree selection, group selection, and SCE. In terms of regeneration densities and composition, how do light availability, competition, seedbad, and …

Estimates of dynamic rate functions for riverine channel catfish, Ictalurus punctatus (Rafinesque), populations are limited. The open nature and inherent difficulty in sampling riverine environments and the propensity for dispersal of channel catfish impede estimation of population variables. However, contemporary population models (i.e. robust design models) can incorporate the open nature of these systems. The purpose of this study was to determine channel catfish population abundance, survival and size structure and to characterize growth in the lower Platte River, Nebraska, USA. Annual survival estimates of adult channel catfish were 13%–49%, and channel catfish abundance estimates ranged from 8,281 to 24,261 …
