An Assessment Of Disinfection-Related Water Chemistry At Public Pools And Spas In Louisville, Kentucky, Thomas Gerding, Tim Wilder, Jason W. Marion
An Assessment Of Disinfection-Related Water Chemistry At Public Pools And Spas In Louisville, Kentucky, Thomas Gerding, Tim Wilder, Jason W. Marion
EKU Faculty and Staff Scholarship
The growth in the number of pools to more than 7.4 million in the U.S. has been accompanied by a rise in recreational water illnesses (RWIs). Effective pool management, though, can mitigate RWI risks. Inadequate management presumably occurs more frequently where training is less formalized and/or pool operation is a minor aspect of the job of the responsible pool manager(s). During summer 2018, weekly evaluations were performed at public venues in Louisville, Kentucky. Disinfectant levels and other items were monitored and compared with venue-specific (pool or spa) criteria. Among 1,312 venue surveys, 1,173 (89.4%) met criteria and 139 (10.6%) did …
Abundance Of Songbirds In Eastern Hemlock Stands Following Chemical Treatment For Hemlock Woolly Adelgid, Natalie Sweeting
Abundance Of Songbirds In Eastern Hemlock Stands Following Chemical Treatment For Hemlock Woolly Adelgid, Natalie Sweeting
Online Theses and Dissertations
In the 1960’s the invasive Hemlock Woolly Adelgid (Adelges tsugae [hereafter, HWA]) began to spread west across the hemlock stands of the Eastern U.S. killing a significant number of Eastern Hemlock (Tsuga canadensis). While chemical treatments, primarily with the active ingredient imidacloprid, have been implemented, their effects on hemlock dependent avian species are largely unknown. A 2009 study, which took place as HWA was beginning to invade Kentucky, identified six indicator species that were positively and negatively correlated with eastern hemlock stands throughout the Appalachian Mountain region of Kentucky. Our study repeated bird and vegetation surveys at the same 65 …
Bee Abundance Along A Tropical Montane Elevational Gradient And Implications For Crop Pollination Services, Kristin M. Conrad
Bee Abundance Along A Tropical Montane Elevational Gradient And Implications For Crop Pollination Services, Kristin M. Conrad
Online Theses and Dissertations
Tropical forests are among the biologically richest ecosystems on Earth, but how most organisms in these forests will respond to a warming climate remains uncertain. Insects are expected to be highly responsive to climate change due to their short life cycles that are strongly influenced by temperature. Plants depend on pollinators to set seed and reproduce, and many animal populations rely on the resources provided by flowering plants. There is an urgent need to document elevational distributions and thermal specialization for tropical bee species to understand how these important pollinators may respond to warming temperatures. My four-year study (2016-2019) aims …
