Estimating Relative Abundance Of Young-Of-The-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Spring 2018, Troy D. Tuckey, Mary C. Fabrizio

Reports

American Eel (Anguilla rostrata) is a valuable commercial species along the Atlantic coast of North America from New Brunswick to Florida. In the U.S., harvests have declined, with similar patterns occurring in the Canadian Maritime Provinces (Meister and Flagg 1997). An average of 62% of the annual landings of U.S. commercial harvest since 1993 have come from the Chesapeake Bay (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division, 9 February 2015). In 2013, Virginia commercial landings were approximately 100,298 lbs; since mandatory reporting began in 1993, average annual landings in Virginia have been 193 ...

In this teaching module, students will explore emerald ash borer (EAB), its impacts on the ash trees, and how warming temperatures could affect EAB populations. The emerald ash borer is a green buprestid or jewel beetle native to north-eastern Asia that causes devastating disease in ash trees.

The Future Of Recreational Fisheries: Advances In Science, Monitoring, Management, And Practice, Jacob W. Brownscombe, Kieran Hyder, Warren Potts, Kyle L. Wilson, Kevin L. Pope, Andy J. Danylchuk, Steven J. Cooke, Adrian Clarke, Robert Arlinghaus, John R. Post

Nebraska Cooperative Fish & Wildlife Research Unit -- Staff Publications

Recreational fisheries (RF) are complex social-ecological systems that play an important role in aquatic environments while generating significant social and economic benefits around the world. The nature of RF is diverse and rapidly evolving, including the participants, their priorities and behaviors, and the related ecological impacts and social and economic benefits. RF can lead to negative ecological impacts, particularly through overexploitation of fish populations and spread of non-native species and genotypes through stocking. Hence, careful management and monitoring of RF is essential to sustain these ecologically and socioeconomically important resources. This special issue on recreational fisheries contains diverse research, syntheses ...

On The Brink Of Extinction: The Fate Of The Pacific Northwest's Southern Resident Killer Whales, Sabrina Wilk

Pomona Senior Theses

The killer whales that roam the northeastern Pacific Ocean have been the objects of studies since the 1970s, making them the most well-studied population of orcas in the world. Three distinct ecotypes of killer whales (Orcinus orca), known as residents, transients, and offshores, share these waters. The ecotypes are morphologically and behaviorally distinct to the extent that some scientists consider them separate species, with residents eating salmon, transients specializing on marine mammals, and offshores preferring Pacific sleeper sharks and Pacific halibut. Resident populations have endeared themselves to the region's locals with their striking black and white markings and their ...

Age-0 Walleye Sander Vitreus Display Length-Dependent Diet Shift To Piscivory, Christopher S. Uphoff, Casey W. Schoenebeck, Keith D. Koupal, Kevin L. Pope, W. Wyatt Hoback

Nebraska Cooperative Fish & Wildlife Research Unit -- Staff Publications

The ontogenetic diet shift to piscivory can be energetically beneficial for fish growth and allows larger, more energetically profitable prey to be consumed. A shift to piscivory may be easier for longer individuals within a cohort due to larger gape size, and an early shift is likely advantageous, potentially leading to increased growth rates and survival. Such length-dependent ontogenetic diet shifts may explain the intracohort variability in length that is common for age-0 walleye (Sander vitreus). The objectives of this study were to describe seasonal intracohort variability in length, identify the timing of the shift to piscivory and determine if ...

Lift On E15 Ban: Should Nebraskan Farmers Be Cheering?, Samantha Wattier

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The common gasoline-ethanol mixture available at gas station pumps is 10% ethanol (E10). The Environmental Protection Agency had a ban on 15% ethanol (E15) during summer months. The news has been covering the talks of President Trump to lifting this summer ban and supporters in Iowa are excited.

Should Nebraska shout Hoorah, too? It is common knowledge Nebraska is better than Iowa. We should be excited, too, right?! NO.

Iowa has been tracking Fuel Revenue sales including those from ethanol blends and has been pushing for the E15 ban lift. Considering Iowa produces MORE corn and MORE ethanol than Nebraska ...

Looking At The True Costs Of Environmental Degradation, Zachery Sehnert

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Progress is why we change, and innovation drives that progress. It is already very clear to scientists around the globe that our current framework for living is not sustainable. 97 percent of climate scientists are in consensus that there is a major threat to our ecosystem and action needs to be taken. Overpopulation, pollution, water scarcity, natural disasters, overfishing, deforestation are all issues that must be reevaluated with sustainability in mind. However only 49 percent of the general population share this belief, and even less, only 29 percent of CEOs are actively addressing climate change. The shortcoming for the general ...

“Renewable Energy Implementation”, William Newcomb

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Finding and providing ways to produce energy in an environmentally clean way is becoming a major push for countries all around the world today. Renewable energy provides a clean way to produce energy efficiently without using our planets non-renewable resources. Renewable energy has been growing substantially in the United States in the last decade and is making its way towards becoming a major energy production method. So, what is stopping the United States from implementing renewable energy production into our country at a mass scale?

There are many barriers that are keeping renewable energy from becoming a main source of ...

Nebraska’S Public Power Is Proof That Renewables Are (Literally) In The Public’S Best Interest, Jacob Monti

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Nebraska is the only state that has every electric utility publicly owned. This gives Nebraska a unique advantage of serving its customers rather than out-of-state shareholders. Since the goal is cheap power instead of profit margins and keeping shareholders happy, Nebraska rates are 16.8% below the national average. (EIA.gov)

So what does that mean for Renewable sources of electricity if cheap power is the main focus? Does cheap but dirty coal reign supreme?

Some might think that’d be a death blow for Renewables. Renewables (wind, solar, and hydro-electric power) are expensive and not profitable, right? WRONG.

Renewables ...

Wave Energy In America, Chris Sukstorf

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The United States has an untapped energy goldmine: our shores. According to the National Oceanic and Atmospheric Administration (NOAA), the United States his home to over 95,000 miles of shoreline. This shoreline is home to beaches, homes, and wildlife, but it could be home to more: wave energy.

Wave energy comes in many forms: some use the bobbing up and down motion of waves to generate energy in a similar motion of a piston; others store water during high tide and then release it during low tide like a dam. All said and done, the United States has the ...

Why Lincoln Needs To Get Ahead Of The Emerald Ash Borer Outbreak, Bryce Meyer

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The emerald ash borer was recently sighted in Lincoln, Nebraska this August. This was to be expected as they were also located in Douglas and Cass county. The emerald ash borer has been making its way west from Michigan and has also been detected in 61 counties in Iowa.

The emerald ash borer is a metallic green colored beetle that feeds on green ash, black ash, blue ash, and white ash trees. The insect can kill up to 99% of the ash trees that they come in contact with. The beetle is native to north-eastern Asia and is considered an ...

“On-Bill Financing: A Bright Idea For Nebraska”, Lauren Taylor

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In over 29 states, a program called On-Bill Financing (OBF) is being utilized to improve the energy efficiency of homes and livelihoods of the people living in them. These programs have been implemented all over the country for many years, in states like Colorado, Hawaii, Iowa, and Michigan. According to the Environmental and Energy Study Institute (EESI), OBF has been wildly successful, reducing energy inefficiency, cutting energy bills, and improving the comfort of homes across the country with no upfront costs.

But what exactly is this mysterious money-saving program, and why hasn’t Nebraska tapped into it yet?

Social Change For A Global Problem, Isabella Catalano

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Recently, the United Nations' International Panel on Climate Change (IPCC) released a new report[1], warning us that storms are becoming more volatile, sea surface temperatures are getting higher, global environment as a whole growing less predictable: in other words, things are about to get a whole lot worse than we predicted.

Unless, of course, we do something about it. The IPCC recommends cutting CO₂ emissions by 45% in order to curb just the worst of climate change's many effects.

There are a plethora of articles on the topic of just what, exactly, we as individuals can do ...

Recycling Just Got More Expensive. Can It Be Done Better?, Zachery Homolka

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

There was a time in history that America led the world in recycling. In World War Two, Americans were asked to recycle tin, steel, paper, and rubber for the war effort. The University of Southern Carolina states that children were so eager to participate, they went door to door collecting recyclable scraps to turn in to be made into tanks, planes, and ammunition. Yet, in 2017 the National Geographic estimated about 91% of plastic produced globally has not been recycled and instead is landfilled or littered into the environment. America is no longer leading the recycling charge, the World Economic ...
