Length-Weight Relationships For Three Asian Carp Species In The Missouri River, Greg Wanner

National Invasive Species Council materials

Bighead carp (Hypophthalmichthys nobilis), silver carp (Hypophthalmichthys molitrix), and grass carp (Ctenopharyngodon idella), collectively referred to as Asian carp, are invasive species that have been introduced into the Mississippi River basin. The expansion of Asian carp into the Missouri River is not well understood and knowledge of population characteristics within this river are lacking. The objectives of this study were to describe the length-weight relationships (condition) of Asian carp from 2003 to 2007 in the Missouri River downstream of Gavins Point Dam, South Dakota and Nebraska to St. Louis, Missouri. All total, 388 bighead, …

Standardized Precipitation Index: User Guide, Michael Hayes, Mark Svoboda, Deborah Wood

Drought Mitigation Center Faculty Publications

Over the years, there has been much discussion on what drought indices should be used in a particular climate and for what application. Many drought definitions and indices have been developed and attempts have been made to provide some guidance on this issue. With this in mind, the Interregional Workshop on Indices and Early Warning Systems for Drought was organized and held at the University of Nebraska-Lincoln, United States of America, from 8 to 11 December 2009. It was jointly sponsored by the School of Natural Resources (SNR) of the University of Nebraska, the United States National Drought Mitigation Center …

Sustainability And Health Impacts Of Pulse Crops In The United States Using Life Cycle Assessment, Prathamesh Bandekar

Graduate Theses and Dissertations

Environmental sustainability and human health impact of pulses produced and consumed in the United States was assessed using life cycle assessment (LCA). The study included three objectives 1) to estimate environmental impact of current production and consumption practices in the United States using attributional LCA; 2) to estimate environmental and human health impact of iso-caloric diets containing varying amounts of pulses using Hybrid-LCA and Combined Nutritional and Environmental-LCA (CONE-LCA); and 3) to estimate environmental impact of increased demand for pulses using consequential LCA. Scope of the study varied for each objective with system boundary encompassing cradle-to-grave activities for objective 1 …

European Starlings: A Review Of An Invasive Species With Far-Reaching Impacts

Managing Vertebrate Invasive Species

The introduction of European starlings (Sturnus vulgaris) in New York City in 1890 and 1891 resulted in their permanent establishment in North America. The successful occupation of North America (and most other continents as well) has earned the starling a nomination in the Top 100 list of ‘Worlds Worst’ invaders. Pimentel et al. (2000) estimated that starling damage to agriculture crops in the United States was $800 million yearly, based on $5/ha damage. Starlings may spread infectious diseases that sicken humans and livestock, costing nearly $800 million in health treatment costs. Lastly, starlings perhaps have contributed to the …

Powering The Machine, Draining The Planet: Whether U.S. Environmental Law Is Equipped To Regulate The Energy And Water Demands Of Ai Data Centers

Journal of Earth and Life Science

Artificial intelligence (AI) data centers have become one of the United States' fastest-growing and least-regulated sources of environmental stress. In 2024 alone, U.S. data centers consumed 183 terawatt-hours (TWh) of electricity more than the entire nation of Pakistan and consumed an estimated 17 billion gallons of water (IEA, 2025; Berkeley Lab, 2024). By 2030, electricity demand from these facilities is projected to reach 426 TWh, a 133% increase in six years (Pew Research Center, 2025). This paper examines whether the existing U.S. environmental regulatory framework put by the National Environmental Policy Act (NEPA), the Clean Water Act (CWA), and the …

Micro-Topographic Control On Soil Moisture And Ph Dynamics In A Northern Peatland Ecosystem: A Case Study From Saco Heath, Maine, Henry Mahoney

Student Publications

Peatland ecosystems are characterized by complex structural microtopography, prominently featuring elevated hummocks and depressed hollows that establish critical micro-environmental and ecohydrological gradients. This study investigates the influence of micro-topographic positioning on soil moisture and pH dynamics at the Saco Heath Preserve; a raised acid bog located in southern Maine. Data collection was focused entirely within Sphagnum moss, which serve as the dominant vegetative component across multiple structural hummocks and hollows. Using a systematic temporal framework and a robust spatial sampling strategy (n = 100 per micro-habitat) between July 16 and August 16, we quantified physical moisture contents and chemical pH …

Managing Non-Native Wildlife In Florida: State Perspective, Policy And Practice

Managing Vertebrate Invasive Species

Florida has more non-native wildlife species than any other state: 439 introduced species of fish, wildlife and marine organisms have been observed and at least 123 are established, i.e., highly unlikely to be extirpated without human intervention. Florida is an epicenter for non-native species with a long established pet industry, major tourist attractions, and major ports, primarily Miami. The large number of established species is due to climate match with that of popular tropical pets, habitat disturbance that facilitates invasion, and a depauperate vertebrate fauna in tropical and subtropical portions of Florida. The Florida Fish and Wildlife Conservation Commission’s approach …

Weed Control Methods Handbook: Tools & Techniques For Use In Natural Areas

All U.S. Government Documents (Utah Regional Depository)

Invasive non-native plants are a serious threat to native species, communities, and ecosystems in many areas around the world. They can compete with and displace native plants, animals, and other organisms that depend on them, alter ecosystem functions and cycles significantly, hybridize with native species, and promote other invaders. The good news is that many plant invasions can be reversed, halted or slowed, and in certain situations, even badly infested areas can be restored to healthy systems dominated by native species. In most instances this requires taking action to control and manage those invasive plants. This handbook provides you with …

Measuring Soil Salinity

Natural resources factsheets

To make sound decisions on managing saline sites, you need to know the source of salt, how salinisation is occurring, the landscape context, and most importantly, the actual salt concentration of the soil.

The most common 'measures' of salt concentration are actually estimates based on electrical conductivity of a soil and water solution. Soil salt content can be measured in a laboratory by measuring the total dissolved solids in a sample. In the field, salt concentration can also be estimated using electromagnetic induction-based soil sensors.
