Vertebrates On The Brink As Indicators Of Biological Annihilation And The Sixth Mass Extinction, Gerardo Ceballos, Paul R. Ehrlich, Peter H. Raven

Harold W. Manter Laboratory of Parasitology: Library Materials

The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services. Here we assess the extinction crisis from a different perspective. We examine 29,400 species of terrestrial vertebrates, and determine which are on the brink of extinction because they have fewer than 1,000 individuals. There are 515 species on the brink (1.7% of the evaluated vertebrates). Around 94% of the populations of 77 mammal and bird species on the brink have been lost in …

Session 6: Innovating The Built Environment Post-Covid-19, Marc Palatucci, Richard Lyall, Timothy Harris, Steven Bender, Peter Smirniotopoulos, Ryan Mathesin

SITIE Symposiums

ABSTRACT: Innovating the Built Environment for a Post-COVID-19 World

It would seem an act of academic malpractice to teach a course titled Innovating the Built Environment: How the Law Responds to Disruptive Change, and host an all-day symposium as an integral part of that course, and not endeavor to address the most-disruptive thing to happen to the built environment in more than 100 years: The coronavirus pandemic. This "disruption" to real estate is the proverbial elephant in the room. Hopefully, it will maintain a minimum six-foot distance from others as we address how it impacts the four Special Topics …

Session 5: Real Estate Tokenization, Joseph Vincent, Steven Bender, Peter Smirniotopoulos

SITIE Symposiums

ABSTRACT: Is “tokenization” the next great leap forward needed to make homeownership more appealing to Millennials and Gen Z’s?

If single-family homeownership and time-sharing had a love child, what would it look like? Is it possible to adapt successful models for office sharing to homeownership so renters who lament not owning an appreciating asset could have a stake in “something” while not being tied down to one specific residential structure or a single geographic location, to make homeownership more attractive to younger generations? And, if so, does blockchain technology hold the key (pun intended) to fractional ownerships in real …

Session 4: Atlanta Beltline, Art Lansing, Rob Turner, Jim Langford, Kristen Lohse, Claire Martini

SITIE Symposiums

ABSTRACT: What Would it Take to Connect All of Greater Seattle’s Neighborhoods with Walking and Biking Trails?

Major U.S. cities have endeavored, independently of each other, over the past several decades to create greenway systems connecting residents and visitors with neighborhoods and attractions, increasing opportunities for walking and biking and reducing their reliance on vehicular traffic. Atlanta’s BeltLine--a twenty-two-mile loop of historic railroad right-of-ways encircling the city’s downtown and midtown areas, seeks to reinvent the city if transformed into a green corridor—is perhaps one of the best examples of how a Seattle Greenway might be accomplished (although Atlanta’s concerted …

Session 2: Wework, Ryan Mathisen, Peter Smirniotopoulos, Paul Swegle

SITIE Symposiums

ABSTRACT: When Worlds Collide: How an 86-Year Old Federal Law (The Securities Act of 1933) Exposed the Flaws in WeWork’s “Innovative Business Model.”

Co-working pioneer WeWork, a wholly owned subsidiary of The We Company, grew meteorically through an extremely aggressive building and master-lease acquisition strategy over the past several years. Substantial, early stage funding from SoftBank, a Japan-based high-tech venture capital investment bank, reinforced WeWork’s unicorn status. But was WeWork’s business model truly unique, bringing with it the promise of a very profitable real estate operating company in the future? Or was it the company’s early stage, venture …

Great Basin Paleoclimate And Aridity Linked To Artic Warming And Tropical Pacific Sea Surface Temperature, Matthew S. Lachniet, Yemane Asmerom, Victor Polyak, Rhawn Denniston

Geoscience Faculty Research

The arid southwestern United States is susceptible to sustained droughts that impact water resources and economic activity for millions of residents. Previous work has not systematically investigated the structure, timing, and possible forcings of Holocene Great Basin sub‐orbital hydroclimate changes, impeding our ability to understand the potential future controls on Southwestern aridity. The objective of this paper is to constrain the potential forcings on Holocene aridity and temperature, via comparison of new high‐resolution speleothem data, an Aridity Index synthesizing hydroclimate records, and linkages of Southwestern paleoclimate to other regions. The high‐resolution data from Leviathan Cave provide a paleoclimate record since …

Combined Use Of Sentinel‐1 Sar And Landsat Sensors Products For Residual Soil Moisture Retrieval Over Agricultural Fields In The Upper Blue Nile Basin, Ethiopia, Getachew Ayehu, Tsegaye Tadesse, Berhan Gessesse, Yibeltal Yigrem, Assefa M. Melesse

National Drought Mitigation Center: Faculty Publications

The objective of this paper is to investigate the potential of sentinel‐1 SAR sensor products and the contribution of soil roughness parameters to estimate volumetric residual soil moisture (RSM) in the Upper Blue Nile (UBN) basin, Ethiopia. The backscatter contribution of crop residue water content was estimated using Landsat sensor product and the water cloud model (WCM). The surface roughness parameters were estimated from the Oh and Baghdadi models. A feed‐forward artificial neural network (ANN) method was tested for its potential to translate SAR backscattering and surface roughness input variables to RSM values. The model was trained for three inversion …

A Hydrometeorological Assessment Of The Historic 2019 Flood Of Nebraska, Iowa, And South Dakota, Paul Xavier Flanagan, Rezaul Mahmood, Natalie Umphlett, Erin M.K. Haacker, Chittaranjan Ray, Bill Sorensen, Martha Shulski, Crystal J. Stiles, David Pearson, Paul Fajman

High Plains Regional Climate Center: Staff Publications

During early 2019, a series of events set the stage for devastating floods in eastern Nebraska, western Iowa, and southeastern South Dakota. When the floodwaters hit, dams and levees failed, cutting off towns, while destroying roads, bridges, and rail lines, further exacerbating the crisis. Lives were lost and thousands of cattle were stranded. Estimates indicate that the cost of the flooding has topped $3 billion as of August 2019, with this number expected to rise.

After a warm and wet start to winter, eastern Nebraska, western Iowa, and southeastern South Dakota endured anomalously low temperatures and record-breaking snowfall. By March …

Optimal Distribution Of Best Management Practices (Bmps) For Urban Stormwater Runoff Quantity And Quality Control, Rezaei Abdul Razaq

Student Works (2020-2029)

The vast development of urban areas throughout the world has substantially impacted the natural landscapes, leading to more imperviousness. Urbanization typically results in a larger amount of runoff volume, increase in flow frequency, duration and peak runoff, faster time of concentration as well as lower infiltration which will affect groundwater recharge. The stormwater runoff quality is also adversely affected in urban areas due to the pollutant loads in stormwater runoff. Best Management Practices (BMPs) and Low Impact Development (LID) have been widely applied to urban impervious surfaces to reduce urban stormwater runoff and improve water quality. In order to achieve …

Geospatial Applications To Mitigate Concentrated Animal Feeding Operations From Impacting Surface Water Resources, Elias Rex

Electronic Theses, Projects, and Dissertations

Concentrated Animal Feeding Operations (CAFOs) offer the ability to meet the rising demands of population growth by housing large amounts of livestock on relatively small areas of land, using medication to accelerate their maturation, and reusing waste products as fertilizers. However, there is a growing abundance of literature related to land use configurations and their effects on water resources, many of which highlight agriculture as a primary contributor of nutrients and fecal bacteria found in surrounding water resources. The purpose of this study is to advance the current knowledge surrounding CAFO land-use and its effect on tributaries within the Cape …

Storm Surges In The Bohai Sea: The Role Of Waves And Tides, Yuanyi Li, Huan Feng, Guillaume Vigouroux, Dekui Yuan, Guangyu Zhang, Xiaodi Ma, Kun Lei

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

A storm surge is a complex phenomenon in which waves, tide and current interact. Even though wind is the predominant force driving the surge, waves and tidal phase are also important factors that influence the mass and momentum transport during the surge. Devastating storm surges often occur in the Bohai Sea, a semi-enclosed shallow sea in North China, due to extreme storms. However, the effects of waves on storm surges in the Bohai Sea have not been quantified and the mechanisms responsible for the higher surges that affect part of the Bohai Sea have not been thoroughly studied. In this …

La Habana: A History Of Society, Livelihood, Movement, And Land Use On The Iquitos-Nauta Highway, Katie Brown

Undergraduate Honors Theses

With increasing infrastructural projects and land titling in the Peruvian Amazon, many changes are occurring within small roadside communities. In this case study, we investigate how these changes impact livelihoods, land use, travel patterns, and social relations within the broader concepts of development, privatization of land, and commodification of nature. Specifically we focus on the caserío La Habana situated on the Iquitos-Nauta highway in the Loreto region of Peru. Semi-formal interviews and ethnographic methods were conducted to gather information on social organization, history of the community, land use practices, migration patterns, opinions on the road, and livelihood strategies. After data …

Modeling Of Distributary Channels Formed By A Large Sediment Diversion In Broken Marshland, Dylan Blaskey

LSU New Orleans Theses and Dissertations

A 2-D DELFT3D model was developed to address the morphological response of Barataria Bay, the sediment deposition rate in the receiving basin, and the impact on the existing distributary channels within the broken marsh system due to the proposed Mid-Barataria Sediment Diversion. The model had a mesh size sufficient to accurately represent the development of the distributary channels, localized flooding, erosion, and salinity in the basin. The model predicts that the receiving basin will experience extensive erosion during the first year the diversion is open creating three major distributary pathways which flood much of the basin in freshwater. Most locations …

Space And Depth-Resolved Naturally Occurring Toxic Groundwater Species In Bangladesh And Rwanda: Origination And Risk Analysis, Kenneth Hamilton

Civil and Environmental Engineering Theses and Dissertations

Access to safe potable water is a necessity for all. Groundwater is a commonly relied upon drinking water source for many areas around the world. This is especially true for communities in high density, rural settings. Such is the case for populations near Cox’s Bazaar, Bangladesh, and in the Bugesera region of Rwanda. Sediment and groundwater contamination, through toxic dissolved species, represents a significant public health risk to exposed populations. Tropical soils, such as the soil profiles in Bangladesh and Rwanda, often contain higher concentrations of heavy metals (Rieuwerts, 2007). Additionally, nitrate from fertilizers, are widely used on the soils …

Synergistic Use Of Remote Sensing And Modeling For Estimating Net Primary Productivity In The Red Sea With Vgpm, Eppley-Vgpm, And Cbpm Models Intercomparison, Wenzhao Li, Surya Prakash Tiwari, Hesham El-Askary, Mohamed Ali Qurban, Vassilis Amiridis, K. P. Manikandan, Michael J. Garay, Olga V. Kalashnikova, Thomas C. Piechota, Daniele C. Struppa

Mathematics, Physics, and Computer Science Faculty Articles and Research

Primary productivity (PP) has been recently investigated using remote sensing-based models over quite limited geographical areas of the Red Sea. This work sheds light on how phytoplankton and primary production would react to the effects of global warming in the extreme environment of the Red Sea and, hence, illuminates how similar regions may behave in the context of climate variability. study focuses on using satellite observations to conduct an intercomparison of three net primary production (NPP) models--the vertically generalized production model (VGPM), the Eppley-VGPM, and the carbon-based production model (CbPM)--produced over the Red Sea domain for the 1998-2018 time period. …
