Bison Movements Change With Weather: Implications For Their Continued Conservation In The Anthropocene, Nicholas A. Mcmillan, Samuel D. Fuhlendorf, Barney Luttbeg, Laura E. Goodman, Craig A. Davis, Brady W. Allred, Robert G. Hamilton
Bison Movements Change With Weather: Implications For Their Continued Conservation In The Anthropocene, Nicholas A. Mcmillan, Samuel D. Fuhlendorf, Barney Luttbeg, Laura E. Goodman, Craig A. Davis, Brady W. Allred, Robert G. Hamilton
Department of Agronomy and Horticulture: Faculty Publications
Animal movement patterns are affected by complex interactions between biotic and abiotic landscape conditions, and these patterns are being altered by weather variability associated with a changing climate. Some animals, like the American plains bison (Bison bison L.; hereafter, plains bison), are considered keystone species, thus their response to weather variability may alter ecosystem structure and biodiversity patterns. Many movement studies of plains bison and other ungulates have focused on point-pattern analyses (e.g., resource-selection) that have provided information about where these animals move, but information about when or why these animals move is limited. For example, information surrounding the …

The Platte River extends about 310 mi (499 km) from North Platte, Nebraska, to its terminus at the Missouri River confluence near Plattsmouth, Nebraska. The Platte River Valley is a continentally significant ecosystem that serves as a major stopover for migratory waterbirds in the Central Flyway including the endangered Whooping Crane (Grus americana) and >1 million Sandhill Cranes (Antigone canadensis) at the peak of spring migration. However, the Platte River Valley also supports a great diversity of avifauna including grassland breeding birds, native stream fish, vascular plants, herpetofauna, mammals, pollinators, and aquatic macroinvertebrates. Despite ongoing conservation …
Understanding Conservation Specialists’ Role In The Adoption Of Precision Agriculture In Nebraska, Morgan L. Register
Understanding Conservation Specialists’ Role In The Adoption Of Precision Agriculture In Nebraska, Morgan L. Register
School of Natural Resources: Dissertations, Theses, and Student Research
There is a complex issue by the need for strategic development of agricultural lands to ensure we can feed a growing world, while simultaneously reducing impacts on our natural resources such as water pollution from runoff, soil degradation, and habitat fragmentation. To address these growing concerns, researchers are looking for ways to optimize both agricultural production and natural resource conservation. Precision conservation was developed to ensure sustainable ecosystems for future generations. Our research evaluates conservation specialists’ ability to clearly articulate how precision conservation can help agricultural producers feed a growing world while simultaneously reducing impacts on our natural resources, I …
Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws
School of Natural Resources: Dissertations, Theses, and Student Research
Marginal cropland is suboptimal due to historically low and variable productivity and limiting biophysical characteristics. To support future agricultural management and policy decisions in Nebraska, U.S.A, it is important to understand where cropland is marginal for its two most economically important crops: corn (Zea mays) and soybean (Glycine max). As corn and soybean are frequently planted in a crop rotation, it is important to consider if there is a relationship with cropland marginality. Based on the current literature, there exists a need for a flexible yet robust methodology for identifying marginal land at different scales, which …
Monarch Butterflies: Rearing Methodologies And The Impact Of Fungicide And Insecticide Exposures, Matthew Greiner
Monarch Butterflies: Rearing Methodologies And The Impact Of Fungicide And Insecticide Exposures, Matthew Greiner
Department of Entomology: Dissertations, Theses, and Student Research
The North American migratory monarch butterfly, Danaus plexippus L., populations has experienced a ca. 90% decline over the past two decades. The decline is attributed to climate change, loss and degradation of overwintering habitat, and the loss of milkweed plants in the midwestern United States. The remaining milkweed stands often occur close to agricultural fields, and efforts to establish additional milkweed on the landscape focus on agricultural systems. However, milkweed plants near agricultural fields are likely exposed to pesticides that could adversely impact monarch caterpillars. Effective management of milkweed habitat supporting monarch caterpillars requires knowledge about the toxicological impacts of …
Essays On Conservation Outcomes On Rented Farmland-Role Of Gender, Diya Ganguly
Essays On Conservation Outcomes On Rented Farmland-Role Of Gender, Diya Ganguly
Department of Agricultural Economics: Dissertations, Theses, and Student Research
The essays in this dissertation explore why female landowners may be less likely than male landowners to achieve long term conservation on their land. In Chapter 1 we develop theory to model the strategic interaction between a landowner and a tenant with a focus on their gender and implementation of conservation practices on land. Within the context of a sequential-move game, we use the principal-agent framework and identity theory to model land-use choice and equilibrium payoffs between landowner and tenant. We consider cash rent lease and discounted lease whereby the tenant pays a reduced rent if they implement conservation practices …

A Perusal On Preservation And Conservation Techniques In The Government Aided College Libraries Of Diamond Harbour And Alipore Subdivision In South 24 Parganas, Bibhash Ram Singha, Bikash Kumar Halder
A Perusal On Preservation And Conservation Techniques In The Government Aided College Libraries Of Diamond Harbour And Alipore Subdivision In South 24 Parganas, Bibhash Ram Singha, Bikash Kumar Halder
Library Philosophy and Practice (e-journal)
The present study is exhibited the preservation and conservation techniques in the college libraries of Diamond Harbour and Alipore subdivisions in the district of South 24parganas. It also discusses degradation problems of print and non-print materials, causes of deterioration of library documents, and different obstacles to using preservation techniques. To secure the library materials in a good manner need to apply the preservation and conservation techniques which include cleaning and dusting, use of insecticides and insect repellent such as Thymol, Dichlorovos, Dursban, Naphthalene balls, Neem leaf, etc., besides that there is a provision for security systems of the college libraries …
A Systematic Map Of Human-Carnivore Coexistence, Cassandre C. Venumière-Lefebvre, Stewart W. Breck, Kevin R. Crooks
A Systematic Map Of Human-Carnivore Coexistence, Cassandre C. Venumière-Lefebvre, Stewart W. Breck, Kevin R. Crooks
USDA Wildlife Services: Staff Publications
Carnivore populations globally have largely declined, and coexistence, where humans and carnivores share landscapes, plays a crucial role in carnivore conservation. However, the term “coexistence” is often used in scientific and popular literature without being clearly defined. Herein, we provide a global perspective on what coexistence is and how it is studied. We conducted a systematic map of 366 articles published between 1987 and 2020 to characterize human-carnivore coexistence literature according to coexistence definitions, temporal trends, geographic and taxonomic focus, and four thematic aspects of coexistence: carnivore ecology, human endeavors, social conflict and human-carnivore conflict. We used chi-squared tests and …
