Using Integral Projection Models To Explore Management Strategies For Silver Carp (Hypophthalmichthys Molitrix), Cameron Coles, Elizabeth Balas, James Peirce, Greg Sandland, Richard Erickson
Spora: A Journal of Biomathematics
Silver carp (Hypophthalmichthys molitrix) are planktivorous fish that were originally introduced to the United States for use in fish production ponds and have since escaped these enclosures and are invading the Mississippi River Basin. The silver carp invasion of the Illinois River has a myriad of negative effects on native ecosystems. In this paper, we introduce key dependencies that are likely important in the population dynamics of silver carp: length-dependent egg production and density-dependent growth. Using movement data between two adjacent pools of the Illinois River, we conduct numerical simulations to explore the theoretical effect of harvesting and …

Modeling Spatial Distributions Of Tidal Marsh Blue Carbon Using Morphometric Parameters From Lidar, Bonnie Turek
Masters Theses
Tidal marshes serve as important “blue carbon” ecosystems that accrete large amounts of carbon with limited area. While much attention has been paid to the spatial variability of sedimentation within salt marshes, less work has been done to characterize spatial variability in marsh carbon density. Driven by tidal inundation, surface topography, and sediment supply, soil properties in marshes vary spatially with several parameters, including marsh platform elevation and proximity to the marsh edge and tidal creek network. We used lidar to extract these morphometric parameters from tidal marshes to map soil organic carbon (SOC) at the meter scale. Fixed volume …

Silver Carp Hypophthalmichthys Molitrix Movements In The Lower Cumberland And Lower Tennessee River, Miranda Belanger
Scholars Week
Silver Carp Hypophthalmichthys molitrix are an invasive species making up a large portion of the fish biomass in the lower portions of the Tennessee River and the Cumberland River. This species is expanding its range throughout the upper portions of these rivers, beginning with Kentucky Lake and Lake Barkley. Silver Carp rarely spawn in Kentucky Lake and Lake Barkley, but they can enter these reservoirs through the lock chamber. Thus, the bottleneck created by lock chambers can be used to control expansion of invasive Silver Carp. Although Silver Carp movement patterns have been studied in other portions of the Tennessee …

Strengthening Collaboration Between Washington State And British Columbia, Ginny Broadhurst, Laurie D. Trautman
Border Policy Research Institute Publications
There are a variety of benefits that arise from collaboration across the Canada-US border. In some sectors, the value of collaboration is measurable. For example, travel or trade volumes can be equated with specific economic benefits. This is the case with tourism and supply chain networks. There are traceable benefits associated with cross-border business integration and the development of a shared 'innovation ecosystem'. However, how does one measure the value of having good relations with neighbors? Or the benefit that result from developing more resilient environmental and economic conditions that are created by joint responses to shared natural disasters? The …

Status Quo Of Research And Suggestions On Reduction Of Non-Co2 Greenhouse Gas Emission From Chinese Farmland, Guangbin Zhang, Jing Ma, Hua Xu, Xiaoyuan Yan
Bulletin of Chinese Academy of Sciences (Chinese Version)
The mitigation of greenhouse gas (GHG) emissions is of great significance for controlling global warming. In 2014, the CH4 and N2O emissions from farmland accounted for 4.3% of the total GHG emissions in China. After the carbon peak target in 2030, fossil energy in China will be gradually replaced by clean energy, and then the contribution of CH4 and N2O emissions from farmland will be enlarged, leaving that the urgency and importance of emission reduction becomes increasingly prominent. However, available technologies of emission mitigation have not been fully adopted and promoted due to the …

VIMS Articles
Introduction: As sea level rises and coastal communities simultaneously grow, road flooding has the potential to significantly disrupt travel along road networks and make houses, businesses, and critical facilities difficult to reach. The impacts of tidal and storm surge flooding on roadways present challenging social and economic considerations for all coastal jurisdictions. Maintenance, public and private accessibility, evacuation routes, emergency services are just a few of the common themes local governments are beginning to address for low-lying roadways currently known to flood. Continuation of these services allows a community to thrive, to maintain or increase its tax base, and to …

Prioritizing The Protection And Creation Of Natural And Naturebased Features For Coastal Resilience Using A Gis-Based Ranking Framework – An Exportable Approach, Jessica Hendricks, Pamela Mason, Julie Herman, Carl Hershner
VIMS Articles
Increasing the preservation and creation of natural and nature-based features (NNBF), like wetlands, living shorelines, beaches, dunes and other natural features to improve community resilience in the face of increasing coastal flooding may be achieved by highlighting the locally relevant benefits that these features can provide. Here we present a novel application of the least-cost geospatial modeling approach to generate inundation pathways that highlight landscape connections between NNBF and vulnerable infrastructure. Inundation pathways are then used to inform a ranking framework that assesses NNBF based on their provision of benefits and services to vulnerable infrastructure and for the broader community …

Drought Stress Prediction And Propagation Using Time Series Modeling On Multimodal Plant Image Sequences, Sruti Das Choudhury, Sinjoy Saha, Ashok Samal, Anastasios Mazis, Tala Awada
Papers in Natural Resources
The paper introduces two novel algorithms for predicting and propagating drought stress in plants using image sequences captured by cameras in two modalities, i.e., visible light and hyperspectral. The first algorithm, VisStressPredict, computes a time series of holistic phenotypes, e.g., height, biomass, and size, by analyzing image sequences captured by a visible light camera at discrete time intervals and then adapts dynamic time warping (DTW), a technique for measuring similarity between temporal sequences for dynamic phenotypic analysis, to predict the onset of drought stress. The second algorithm, HyperStressPropagateNet, leverages a deep neural network for temporal stress propagation using hyperspectral imagery. …

Rhino Conservation In Africa, Andrew N. Rowan
WellBeing News
The recovery of white rhinos from a small population of 20 animals in 1895 to tens of thousands today is a major conservation success story, but we are again facing a rapid decline in the numbers of both species of African rhinoceros due mainly to poaching. Demand for rhino horn, mainly from the Far East, has led to an epidemic of poaching. The healthy population of white rhinos in South Africa’s Kruger National Park has fallen from just under 12,000 individuals in 2010 to around 2,200 in 2022. At the current rate of decline, white rhinos will be eliminated from …

We are in a modern biodiversity crisis that will restructure community compositions and ecological functions globally. Large mammals, important contributors to ecosystem function, have been affected directly by purposeful extermination and indirectly by climate and land-use changes, yet functional turnover is rarely assessed on a global scale using metrics based on functional traits. Using ecometrics, the study of functional trait distributions and functional turnover, we examine the relationship between vegetation cover and locomotor traits for artiodactyl and carnivoran communities. We show that the ability to detect a functional relationship is strengthened when locomotor traits of both primary consumers (artiodactyls, n …

Environmental Science and Policy: Faculty Publications
Since 2012, students and others have pushed U.S. Higher Education Institutions (HEIs) to divest their endowments from fossil fuel producing industries. In the past decade, fossil fuel divestment has become the fastest growing divestment movement in history, with over 140 U.S. HEIs announcing divestment commitments. We conduct a quantitative analysis of the three phases of U.S. 4-year HEI divestment announcements (as well as rejections of divestment) to better understand the dynamics. Announcements began (2012-2017) with a number of schools divesting, followed by a second phase where new divestment announcements slowed. The current phase, which began around 2019, shows a renewed …
