Recreational fisheries (RF) are complex social-ecological systems that play an important role in aquatic environments while generating significant social and economic benefits around the world. The nature of RF is diverse and rapidly evolving, including the participants, their priorities and behaviors, and the related ecological impacts and social and economic benefits. RF can lead to negative ecological impacts, particularly through overexploitation of fish populations and spread of non-native species and genotypes through stocking. Hence, careful management and monitoring of RF is essential to sustain these ecologically and socioeconomically important resources. This special issue on recreational fisheries contains diverse research, syntheses ...

Imidacloprid Persistence, Mobility, And Effect On Ecosystem Function, Joanna Hardin 2018 East Tennessee State University

Imidacloprid Persistence, Mobility, And Effect On Ecosystem Function, Joanna Hardin

Electronic Theses and Dissertations

Imidacloprid is a neonicotinoid pesticide used to protect against biting and sucking insects. Land managers rely on its systemic properties, however long-term studies investigating imidacloprid effects on ecosystem function are limited. This study investigated imidacloprid applications to Tsuga caroliniana and Tsuga canadensis over time and compared concentrations to measures of ecosystem function including soil respiration, microbial function, and invertebrate density. Results indicate that imidacloprid is persistent (p0.5). Microbial function and invertebrate density were not significantly different between control and treatment locations nor did imidacloprid concentrations correlate with ecosystem functional indicator activity (p>0.05). It is evident that imidacloprid ...

Knowledge of BC emissions from TPPs is important in characterizing regional carbonaceous particulate emissions, understanding the fog/haze/smog formation, evaluating regional climate forcing, modeling aerosol optical parameters and concentrations of black carbon, and evaluating human health. Furthermore, elevated BC concentrations ...


Assessing Soil Redox Conditions Using Iris Tubes In A Central Georgia Wetland, Cameron Skinner 2018 Georgia College and State University

Assessing Soil Redox Conditions Using Iris Tubes In A Central Georgia Wetland, Cameron Skinner

Georgia Undergraduate Research Conference (GURC)

The process of documenting soil redox potential has become increasingly important to environmental professionals for use in wetland delineation studies. Wetlands are characterized by hydric soils, which are formed in saturated conditions, and are typically home to an anaerobic, reducing redox environment. Most established wetland delineation studies document soil redox conditions through Eh measurements via platinum electrodes and/or alpha-alpha-dipyridyl dye. However, these methods are costly, time-intensive, and complex. An alternative method of assessing reduction potential in situ is through the use of Iron Reduction in Soils (IRIS) tubes, which are fabricated from PVC pipes that have been sanded and ...

Metabolomics For Biomonitoring: Evaluation, Recommendations, And Test Of Efficacy, Sarah M. Mckenzie

Electronic Thesis and Dissertation Repository

Effective biomonitoring of aquatic environments is an integral component of ecosystem protection. The metabolome is an emerging indicator that may have the potential to serve as an ideal bioindicator due to its intrinsic capacity to detect physiological changes in organisms that could foreshadow ecosystem change. My thesis consisted of two complementary objectives. First, the metabolome was evaluated against several established criteria for an ideal bioindicator and found to have significant potential. Recommendations were also made regarding implementation of the metabolome into existing biomonitoring programs. Second, the metabolome of Hexagenia spp. was evaluated as a potential indicator for environmental effects of ...

Due to urban expansion, economic development, and rapid population growth, land use/land cover (LULC) is changing in major cities around the globe. Quantitative analysis of LULC change is important for studying the corresponding impact on the ecosystem service value (ESV) that helps in decision-making and ecosystem conservation. Based on LULC data retrieved from remote-sensing interpretation, we computed the changes of ESV associated with the LULC dynamics using the benefits transfer method and geographic information system (GIS) technologies during the period of 1992–2018 following self-modified coefficients which were corrected by net primary productivity (NPP). This improved approach aimed to ...
