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 ...


In The Eye Of The Storm: Houston After Hurricane Harvey, Brandon Tolentino-Serrano 2019 Claremont Colleges

In The Eye Of The Storm: Houston After Hurricane Harvey, Brandon Tolentino-Serrano

Pomona Senior Theses

Situated in one of the wettest climates in America, Houston, TX has had a long history of heavy rains and unprecedented floods. Unfortunately, floods have become more common over the last few decades as climate change increases the frequency and intensity of hurricanes around the globe. To complicate matters further, Houston has quickly sprawled to accommodate over 2.5 billion people. Rapid urbanization has rendered the landscape even more susceptible to floods through excess concretization and watershed disturbance. This thesis traces the history of the Bayou City in relation to the damages caused by Hurricane Harvey. By mapping out the ...


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 2019 MN DNR Fisheries

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 ...

An Examination Of What Motivates Utah Residents To Adopt The Practice Of Rainwater Harvesting, D. Wayne Honaker

All Graduate Theses and Dissertations

Although most of the earth is covered in water, a very limited amount of that water is fresh water, which is essential to our survival. Therefore, it is imperative that we do all that is possible to conserve and protect our extremely limited water resources, especially in arid regions such as the American West. While there are many ways and means to protecting and preserving our water resources, this thesis focuses on the strategy of rainwater harvesting (RWH) as it is done throughout the state of Utah. RWH is defined as taking the precipitation that falls on our built structures ...

Energy And Water Assessment And Plausibility Of Reuse Of Spent Caustic Solution In A Midwest Fluid Milk Processing Plant, Carly Rain Adams

Dissertations, Theses, & Student Research in Food Science and Technology

The Food Energy and Water Nexus (FEW Nexus) is the inseparable connection linking these resources. The concept of the FEW Nexus within the food industry addresses the connection of water and energy as key members of food production. The steady increase in population and the increase in food demand are directly related, therefore, the need for water and energy. Immediately taking on this critical challenge will lead to tangible impacts on the water and energy crisis facing the food system. To reduce the distance between process productivity and resource efficiency it must first be determined, within food processing, where water ...

High-Resolution Digital Surface Characterization Of The Rio Chama In New Mexico, Rowan L. Converse

Shared Knowledge Conference

Over the past eighty years, the Rio Chama, a major tributary of the Rio Grande in New Mexico, has been subject to significant disruption of historic hydrological flow regimes due to water use demands. In recent years, a multiagency management effort has been initiated to restore some measure of historic flow regimes in the 39.6 km congressionally designated Wild and Scenic stretch through the Rio Chama Canyon Wilderness. We collaborated with managers at the US Army Corps of Engineers to collect approximately 15,870 frames of 10cm resolution multispectral imagery of the 82 km stretch of the river between ...


Water Flow Net Characterization By Using A Tank Model: Preliminary Outcome, Jasmin Budhan, Nazrul I. Khandaker, Stanley Schleifer 2018 CUNY York College

Water Flow Net Characterization By Using A Tank Model: Preliminary Outcome, Jasmin Budhan, Nazrul I. Khandaker, Stanley Schleifer

Publications and Research

A model study was conducted to observe and characterize the flow of water through sandy soil. One of the most relevant tools used for characterizing groundwater flow is the flow net. Assuming that water is incompressible and there is zero volume change in the soil mass, it is known that the total rate of inflow is to equal the total rate of outflow. Thus, following the principle of flow continuity, we use the Laplace equation of continuity, to observe the concept of the flow net. Computing the flow through a miniature channel, we observed the total head difference from the ...

Lithologic Constraints On The Hydrological Parameters Of Regional Aquifers In The Ibb Province, West-Central Region Of Yemen (Middle East), Malek Shami, Zarine Ali, Wedad Abdurabu, Nazrul I. Khandaker, Stanley Schleifer

Publications and Research

The lithology of the Ibb Province Yemen (Middle East) consists of Precambrian gneissic bedrocks with post-tectonic intrusions of granite and granodiorite. The overall topography is dominated by extensive volcanic extrusions that randomly surround Ibb Province with minimal Mesozoic sedimentary outcrops. According to the Yemen Geological Survey and Mineral Resource Board (YGSMRB), the origin and age of such extrusive bodies that manifest on the surface as dikes, lava flows, and small (currently passive) cinder-cone volcanoes are of Cenozoic age associated with the rifting episode of the Arabian Peninsula and subsequent opening of the Red Sea. The overall aerial extension of the ...

Groundwater Recharge Response To Reduced Irrigation Pumping In Western Nebraska, Justin Philip Gibson 2018 University of Nebraska-Lincoln

Groundwater Recharge Response To Reduced Irrigation Pumping In Western Nebraska, Justin Philip Gibson

Dissertations & Theses in Natural Resources

Given current and continued investment in irrigation scheduling technologies, a need exists to better estimate the longevity and magnitude of water savings at watershed level to avoid the paradox of irrigation efficiency. This paradox occurs within a watershed as not all irrigation inefficiencies lead to the system losing water. For example, irrigation pumping rates in excess of crop water demand may lead to enhanced groundwater recharge or surface runoff that migrates to a stream. Thus, increases in efficiency may not lead to similar magnitudes of water savings. I hypothesize that water savings longevities are short given previous work demonstrating rapid ...
