The purpose of this investigation was to systematically examine the variability associated with temporally-oriented invertebrate data collected by citizen scientists and consider the value of such data for use in stream management. Variability in invertebrate data was estimated for three sources of variation: sampling, within-reach spatial and long-term temporal. Long-term temporal data were also evaluated using ordinations and an Index of Biotic Integrity (IBI). Through two separate investigations over an 11-year study period, participants collected more than 400 within-reach samples during 44 sampling events at three streams in the western United States. Within-reach invertebrate abundance coefficient of variation (CV) ranged …

The Millennium Drought taught Australians many lessons about living under extremely dry conditions – not just about how to conserve water, but also about human suffering.
In a drought, farmers find it more difficult to make an income, leading to mental health problems and raising the rate of male suicides. In the city, the impact is felt through water restrictions and more expensive infrastructure.
With very dry conditions returning to Tasmania, central Queensland and western Victoria, are we better prepared for the next big drought?
This is an issue not just for Australia, but across the world, from California, to …

Improved Microplate Fluorometric Soil Enzyme Assay For Β-Glucosidase Detection, Emily C. Hoehn
School of Natural Resources: Dissertations, Theses, and Student Research
Soil microbes produce extracellular enzymes responsible for degrading complex organic compounds to release energy and nutrients. Measurement of soil enzymes can be considered an indicator of soil health and microbial community composition because of its sensitivity to agricultural and management practices. Fluorescence enzyme assays tend to be more sensitive than spectrophotometric (ie. colorimetric) assays and a 96-well plate has the potential capacity for high-throughput use. Development of a newly modified enzyme assay using fluorometric (4-methylumbelliferone), automated pipetting system and sonication, as well as a reduction in replicates allows for a higher sample throughput rate suitable for service laboratory use. The …

Thermal and multispectral remote sensing data from low-altitude aircraft can provide high spatial resolution necessary for sub-field ( 10 m) and plant canopy (1 m) scale evapotranspiration (ET) monitoring. In this study, highresolution (sub-meter-scale) thermal infrared and multispectral shortwave data from aircraft are used to map ET over vineyards in central California with the two-source energy balance (TSEB) model and with a simple model having operational immediate capabilities called DATTUTDUT (Deriving Atmosphere Turbulent Transport Useful To Dummies Using Temperature). The latter uses contextual information within the image to scale between radiometric land surface temperature (TR) values representing hydrologic limits of …

Decomposition and nutrient cycling form the basis of every ecosystem. Nutrient availability in the soil affects plant species composition, richness, and productivity. The Amazon rainforest is known for its unusually fast nutrient cycle, but many aspects lack detailed study and analysis. This comparative study carried out in the Ecuadorian Amazon had four primary objectives related to understanding the nutrient cycle in the Amazon; 1.) analyze soil characteristics, 2.) assess insect diversity in the leaf litter layer, 3.) examine root characteristics, and 4.) measure the decomposition rate between Varzea and Terra Firme habitats alongside the Rio Napo.

At a recent event a colleague asked me, “So what do you do at CERCOM?” My immediate response was the “M” word fundamentally! After 45 years involved in environmental sciences, monitoring remains the most important and critical aspect of not only any field station in support of the academics conducted, but the seminal responsibility to be able, as a scientist, to reveal trends in the massive volume of data collected through routine monitoring exercises. It is extremely rare for a single data point, or even a single season of data, no matter how accurate the individual data point is, to …

Hydraulic fracturing is the process of extracting natural gas from layers of shale rock beneath the surface of the Earth. The largest source of natural gas in the US is the Marcellus Shale, largely located in Pennsylvania, and it is believed to hold about 141 trillion cubic feet of natural gas in its shale deposits. My study examined the impacts of well sites on land cover and land use, the viewshed, and the audioshed. To study the effect of wellpads on land use and land cover, we overlaid a layer of wellpads over land cover data as well as a …

"Tallgrass prairies are the most endangered ecosystem in North America” (Helen et al 2013). “Surveys suggest that since European settlement, declines in area of native prairie range as high as 99.9%”(Sampson, Fred and Fritz Knopf 1994). Prairie ecosystem services are abundant and range from mitigating floods to promoting biodiversity. (USDA Forest Service).Given these benefits, restoring prairies and maintaining native areas should be an important conservation priority. Nematodes, the most abundant animal species on earth, have been used as bio-indicators of soil quality (Neher; Todd). To better understand the dynamics of nematode diversity in native and restored prairies we examines whether …

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 …

Avifaunal Community Composition In A Tropical Forest Corridor: A Case Study From The Atherton Tableland, North Queensland, Don Jones
Independent Study Project (ISP) Collection
Bird communities in tropical forest ecosystems are highly threatened by habitat loss and fragmentation. Replanted corridors connecting isolated forest remnants are a popular method of ameliorating certain negative impacts of habitat fragmentation. Such linkages can theoretically facilitate greater dispersal, increase gene flow, and reduce the risk of local extinctions in forest birds. However, relatively few studies have examined the utilization of reforested corridors by birds, and little hard data exists to support claims that this type of resource and time intensive project is the best use of often scarce funding for conservation. This study examined the avifaunal community present in …

Effects Of Meteorological Conditions On Sulfur Dioxide Air Pollution In The North China Plain During Winter Of 2006–2015, Chase C. Calkins
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
The last decade has seen frequent occurrences of severe air pollution episodes of high concentration in SO2 during winters in the North China Plain (NCP). Using satellite data from the Ozone Monitoring Instrument (OMI), chemistry transport model (GEOS-Chem) simulations, and National Center for Environmental Predication (NCEP) meteorological reanalyzes, this study examines meteorological and synoptic conditions associated with these air pollution episodes during winters of 2006-2015. OMI-based data suggest a large decrease (~30% in area average) of emission since 2010. Statistical analyzes show that meteorological conditions associated with the top 10% of OMI-based high days are found in average to …

A Simulation-Based Analysis Of Chemical And Radiological Hazard Zones Adapted To Physical Boundaries, Mickie J. Sundheim
Theses and Dissertations
In the United States, industrial and terrorist use of chemical, biological, radiological, and nuclear (CBRN) materials pose a risk to public safety. During the initial phase of typical CBRN incidents, emergency responders establish hazard zones based on standard distances from published guidelines and recommendations. This research investigates how standard hazard zones change in a real world environment that accounts for physical boundaries. Using a python simulation in ArcGIS®, new hazard zones were created by expanding standard hazard zones to follow nearby roads, railroads, and rivers. The new and standard zones were compared by calculating the population and area affected by …
