The Effect Of Soil Ph On The Integument Of Western Tiger Salamanders, Aaron Devine, Dennis M. Ferraro

UCARE Research Products

This study was done in an effort to better understand the multifaceted issues in amphibian decline, specifically within the eastern regions of Nebraska, to determine whether or not human-induced acid rain contributed to the decline. This is a heavily important topic of research as amphibians worldwide are declining related to many issues that stem from climate change and several other environmental issues of that nature. This study looked to use acidic pH within soil from western Nebraska to determine the reactionary impacts (primarily lesions) the western tiger salamander had after being subjected to it. It was found that pH did …

Iron Mobility In Desert Sandstone Aquifers: The Possible Role Of Siderite, Lubna Al Azri, David Loope

UCARE Research Products

Jordanians and a large number of refugees are drinking radiumcontaminated water from a sandstone aquifer. The problem is that this water passed through sandstone of the Disi Formation only after carbon dioxide and methane had bleached the sandstone, dissolving the Iron-oxide coatings and liberating heavy metals and radionuclides . The Iron that once coated the grains migrated to form Iron bands in the lower Um Ishrin Formation.

The major practical significance of this study involves water quality. The movement of Iron sandstone aquifers can drastically change groundwater chemistry; understanding how and when this movement takes place will help in locating …

Viability Of The Use Of Electromagnetic Induction To Predict Streambed Properties, Alexandra R. Hruby

UCARE Research Products

This study examined whether electromagnetic induction is a reliable tool to predict various streambed properties, including water conductivity, water temperature, and hydraulic conductivity. The test site was along the North Loup River, outside of St. Paul, Nebraska. Electromagnetic induction was performed using a field portable, multi-frequency EMI tool. Hydraulic conductivity was measured using the falling-head permeameter test, and water temperature and conductivity were measured using handheld meters. The study found that there is a strong positive correlation between water conductivity and apparent electrical conductivity measured by electromagnetic induction. This relationship can be explored further through the analysis of spatial patterns …
