As I sat there in the Members Lounge at the Explorers Club; the world center for exploration, getting ready for our first Spring Saturday Science for Students @the EC lecture, I was putting together some notes on the accomplishments of our science students and CERCOM over the last few months since our last newsletter. Our visit to the Galapagos, a spectacular academic experience for our Molloy College students was at the top of my list! This was certainly not an epiphany but as I accumulated the items on this list, I was impressed not only with what we have conducted …

Chronic Effects Of Lead Exposure On Topsmelt Fish (Atherinops Affinis): Influence Of Salinity, Organism Age, And Relative Sensitivity To Other Marine Fish, Erik J. Reynolds, Tham C. Hoang, D. Scott Smith, Jasim M. Chowdhury
School of Environmental Sustainability: Faculty Publications and Other Works
The aim of this study was to determine the influence of salinity and organism age on the chronic toxicity of waterborne lead (Pb) to Atherinops affinis and to compare the relative Pb sensitivity of A. affinis with other marine species. Chronic Pb exposure experiments were conducted in a water flow‐through testing system. Survival, standard length, dry weight, and tissue Pb concentration were measured and lethal concentrations (LC), effective concentrations (EC), and bioconcentration factor (BCF) were calculated. In general, increasing salinity and organism age decreased Pb toxicity. The LC50s for larval fish at 14 and 28 ppt salinity were 15.1 and …

Influence Of Recreational Activity On Water Quality Perceptions And Concerns In Utah: A Replicated Analysis, Matthew J. Barnett, Douglas Jackson-Smith, Melissa Haeffner
Environmental Science and Management Faculty Publications and Presentations
Both social structural factors and direct sensory experiences can contribute to the development of environmental perceptions and concerns. We use two separate surveys of Utah adults to explore the association between sociodemographic characteristics and participation in recreational activities on water quality perceptions and concerns. We find that engaging in outdoor recreation is systematically associated with more positive water quality perceptions and higher levels of concern about impaired water quality. However, water quality perceptions appear to be shaped more by social characteristics (age, education, gender, race, religion, and income) and by generic measures of overall recreation behavior than by indicators of …

Agricultural Intensification In The Midwest: Impacts On Regional Surface Humidity, Andrew Hill
All Graduate Theses, Dissertations, and Other Capstone Projects
An overwhelming majority of anthropogenic climate change studies have placed emphasis on biogeochemical agents, chiefly carbon dioxide emissions, which operate on a global scale. Fewer studies focus on biophysical factors such as land use/ land cover which operate on a regional or local scale. The impact from biophysical factors will continue to be reinforced with a growing human population and expanding resource demands. Of these factors, agricultural land use represents one of the largest, most extensive, and vital land use allocations.
The U.S. Midwest, dominated by rain-fed corn and soybean agriculture, is a key agricultural region which is lacking in …

Wastewater workers are exposed to different occupational hazards such as chemicals, gases, viruses, and bacteria. Personal Protective Equipment (PPE) is a significant factor that can reduce or increase the probability of an accident from hazardous exposures to chemicals and microbial contaminants. The purpose of this study was to identify wastewater worker’s beliefs and practices on wearing PPE and protections offered by PPE through the integration of the Health Belief Model (HBM). Participants were workers in the wastewater industry, which included wastewater operators, laboratory analysts, maintenance workers, wastewater collection workers, equipment operators, managers, and supervisors (n=272). The instrument was a self-administered …

Fate Of Methoprene In Temperate Salt Marsh Ditches Following Aerial Applications, David J. Tonjes, Anne E. Mcelroy, Robin K. Barnes, Dominick V. Ninivaggi, Walter Dawydiak, Gregory T. Greene, Bruce J. Brownawell
Technology & Society Faculty Publications
Aerial applications of liquid methoprene are used in salt marshes to control mosquitoes by preventing adult emergence. Despite concern about toxicity to non-target organisms, little is known about environmental concentrations after applications, nor methoprene's persistence in salt marsh environments. Aqueous and sediment samples were collected from two marshes receiving weekly applications. Aqueous samples were collected as early as 30 minutes after applications and as long as nine days afterwards; sediment samples were taken within hours of application and as long as 19 days post-application. Use of time-of-flight liquid chromatography – mass spectral analysis allowed for ultra low detection limits (0.5 …

Presence And Potential Sources Of Pharmaceutical And Personal Care Product Chemicals In Messalonskee Lake, Alyssa T. Kullberg
Honors Theses
Pharmaceuticals and personal care product chemicals (PPCPs) represent a large group of contaminants that are mostly not regulated in surface or drinking water and whose presence and environmental and health impacts are poorly understood. We investigated the presence and potential sources of 18 PPCPs in Messalonskee Lake. We collected samples four times over the summer of 2017 at 13 sites around the lake. Samples were tested for PPCPs using liquid chromatography-tandem mass spectrometry. We detected five out of the 18 PPCPs we tested for at the ng/L level: caffeine, 1,7-dimethylxanthine, acetaminophen, sulfachloropyridazine, and amphetamine. PPCPs showed a significant positive correlation …

Recent advancements in information technology and data acquisition have created both new research opportunities and new challenges for using big data in ornithology. We provide an overview of the past, present, and future of big data in ornithology, and explore the rewards and risks associated with their application. Structured data resources (e.g., North American Breeding Bird Survey) continue to play an important role in advancing our understanding of bird population ecology, and the recent advent of semistructured (e.g., eBird) and unstructured (e.g., weather surveillance radar) big data resources has promoted the development of new empirical perspectives that are generating novel …

A Framework For Tracing Social–Ecological Trajectories And Traps In Intensive Agricultural Landscapes, Daniel R. Uden, Craig R. Allen, Francisco Munoz-Arriola, Gengxin Ou, Nancy Shank
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Charting trajectories toward sustainable agricultural development is an important goal at the food–energy–water–ecosystem services (FEWES) nexus of agricultural landscapes. Social–ecological adaptation and transformation are two broad strategies for adjusting and resetting the trajectories of productive FEWES nexuses toward sustainable futures. In some cases, financial incentives, technological innovations, and/or subsidies associated with the short-term optimization of a small number of resources create and strengthen unsustainable feedbacks between social and ecological entities at the FEWES nexus. These feedbacks form the basis of rigidity traps, which impede adaptation and transformation by locking FEWES nexuses into unsustainable trajectories characterized by control, stability, and efficiency, …

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Several frameworks have been developed to assess the resilience of social-ecological systems, but most require substantial data inputs, time, and technical expertise. Stakeholders and practitioners often lack the resources for such intensive efforts. Furthermore, most end with problem framing and fail to explicitly address trade-offs and uncertainty. To remedy this gap, we developed a rapid survey assessment that compares the relative resilience of social-ecological systems with respect to a number of resilience properties. This approach generates large amounts of information relative to stakeholder inputs. We targeted four stakeholder categories: government (policy, regulation, management), end users (farmers, ranchers, landowners, industry), agency/public …

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
The distribution of pattern across scales has predictive power in the analysis of complex systems. Discontinuity approaches remain a fruitful avenue of research in the quest for quantitative measures of resilience because discontinuity analysis provides an objective means of identifying scales in complex systems and facilitates delineation of hierarchical patterns in processes, structure, and resources. However, current discontinuity methods have been considered too subjective, too complicated and opaque, or have become computationally obsolete; given the ubiquity of discontinuities in ecological and other complex systems, a simple and transparent method for detection is needed. In this study, we present a method …

Effects Of Large-Scale Wetland Loss On Network Connectivity Of The Rainwater Basin, Nebraska, Bram H. F. Verheijen, Dana M. Varner, David A. Haukos
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Context The Rainwater Basin region in south-central Nebraska supports a complex network of spatiallyisolated wetlands that harbor diverse floral and faunal communities. Since European settlement, many wetlands have been lost from the network, which has increased distances among remaining wetlands. As a result, populations of wildlife species with limited dispersal capabilities may have become isolated and face greater local extinction risks.
Objectives We compared the pre-European settlement and current extent of the Rainwater Basin network to assess the effects of wetland losses on network connectivity for a range of maximum dispersal distances.
Methods We constructed network models for a range …

Bipartite Networks Improve Understanding Of Effects Of Waterbody Size And Angling Method On Angler–Fish Interactions, Christopher J . Chizinski, Dustin R. Martin, Daizaburo Shizuka, Kevin L. Pope
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Networks used to study interactions could provide insights to fisheries. We compiled data from 27 297 interviews of anglers across waterbodies that ranged in size from 1 to 12 113 ha. Catch rates of fish species among anglers grouped by species targeted generally differed between angling methods (bank or boat). We constructed angler–catch bipartite networks (angling method specific) between anglers and fish and measured several network metrics. There was considerable variation in networks among waterbodies, with multiple metrics influenced by waterbody size. Number of species-targeting angler groups and number of fish species caught increased with increasing waterbody size. Mean number …
