Ponca State Park Vascular Plant Species List
A list of vascular plant species found in Ponca State Park. Arranged by plant family and then species name. Also included are descriptions of locations where the species is commonly found.
Wildcat Hills Rare Plant Survey Final Report
This survey report summarizes fifteen days of field work in eleven sites scattered across the Wildcat Ridge that were completed between May and August of 1996. Forty-five occurrences of 15 plant species on the Nebraska Natural Heritage element list were found. Ten tracts of high quality (or otherwise noteworthy) native communities were identified. ...
Groundwater Modeling of the Ogallala Aquifer: Use of Machine Learning for Model Parameterization and Sustainability Asse...
Addressing groundwater depletion problems in heterogeneous aquifer systems is a challenge. The heterogeneous Ogallala Aquifer, a critical source of groundwater in the central United States, has undergone decades of decline in water levels due to pumping. This project aims to build a robust groundwater model to evaluate optimal scenarios for sustain...
Conservation Decision Making and Agricultural Land Leasing - An Experimental Investigation of the Role of Gender
This research investigated the impact of landowner gender and of the different types of contract leases offered by them to a male tenant, on the conservation (or non-conservation) choice made by the tenant. Specifically, we investigate if a) female and male landowners offer different rental contracts and b) whether tenants choose different actions ...
Assessing, Restoring, and Centering Social-Ecological Relationships for Advancing Social-Ecological Resilience in the No...
The Northern Great Plains grasslands are social-ecological systems that were shaped by evolutionary and Indigenous social-ecological relationships. European colonization disrupted many of these interactions, including the coupling of fire and grazing, and degraded social-ecological resilience, shifting these grasslands to a new state. For those rea...
Applying Circuit Theory to Describe Changes in Structural Landscape Connectivity in Response to Wildfire
Understanding and conserving ecological connectivity is critical to the preservation of vulnerable landscapes. Circuit theory, in which landscapes are imagined as circuit boards with varying resistances to the flow of current, is being increasingly used to model spatially explicit connectivity of landscapes and to inform land management and conserv...
Analysis of Drought-Flood Abrupt Alternation Events and Their Impacts in Kenya
Drought-Flood Abrupt Alternation (DFAA) is a compound disaster event that refers to the abrupt shift of extreme drought events to extreme floods resulting in exacerbated impacts on already vulnerable communities and hindering their coping abilities. This study aimed to analyze drought-flood abrupt alternation events and their impacts in Kenya. The ...
Remotely Sensed Early Warning of Algal Blooms in an Eastern Nebraska Reservoir: A Comparison of Temporal and Spatial Ind...
Cyanobacterial harmful algal blooms (CyanoHABs) detrimentally affect human, animal, and ecosystem health. Remotely sensed early warning systems for cyanoHABs in inland lakes could contribute to more proactive water quality monitoring and help mitigate negative impacts. Advances in freely available remote sensing imagery, with finer spatial, tempora...
Spatiotemporal Plasticity in Reproductive Readiness and Recruitment of Ichthyoplankton of Invasive Silver Carp along a W...
Individuals of invasive species at the edge of their invasion distribution may exhibit enhanced reproductive capacity and phenotypic plasticity leading to accelerated range expansion. Environmental conditions in highly fluctuating environments at distribution edges may either promote or hinder such reproductive readiness and phenotypic plasticity. ...
Integration of MATLAB and Machine Learning to Accelerate Evaluation of Biological Activity in Agricultural Soils and Pro...
Traditionally, assessments of soil biological activity have been confined to laboratory settings, creating a disconnect with practical in-field methods. To bridge this gap, cotton fabric degradation has been used to illustrate soil microbial activity under different management practices. While effective, these demonstrations are subjective and labo...
