Forensic Markers Of Lampricide Toxicity In Oncorhynchsus Mykiss, Chris White
Forensic Markers Of Lampricide Toxicity In Oncorhynchsus Mykiss, Chris White
Theses and Dissertations (Comprehensive)
The lampricide 3-trifluoromethyl-4-nitrophenol (TFM) has been used for decades to control invasive sea lamprey (Petromyzon marinus) populations in the Great Lakes, normally with little harm to other fish populations. However, due to the nature of lampricide treatments and the chemical properties of TFM, adverse effects to non-target fishes and non-target mortality occasionally occur. However, investigations of non-target mortality can be complex, particularly if fish deaths are not noticed immediately, due to decomposition of the carcasses. The objectives of this thesis were to expose rainbow trout (Oncorhynchsus mykiss) to TFM in order to: (i) identify forensic markers …
Development Of Culturing Methods For Native Mayfly Taxa For Use In Laboratory Toxicity Testing, Kevin Nicholas Rowsey
Development Of Culturing Methods For Native Mayfly Taxa For Use In Laboratory Toxicity Testing, Kevin Nicholas Rowsey
Theses, Dissertations and Capstones
Salinity is increasing in freshwaters throughout the world due to anthropogenic impacts with the implication of the increases to biological communities only now being realized. Declining mayfly populations in Appalachian streams have generated increased interest in elevated dissolved solids in that region and their effect on benthic macroinvertebrates, particularly the sensitive Ephemeroptera taxa. Field and laboratory evaluations have indicated high sensitivity of mayflies to elevated dissolved solids. The research described herein is part of an ongoing effort to provide opportunity for toxicity testing with native mayflies in the laboratory. A successful endeavor would establish mayfly sensitivity to total dissolved solids …
Causes, Extent, And Consequences Of Lead-Pellet Ingestion By Chukars (Alectoris Chukar) In Western Utah: Examining Habitat, Search Images, And Toxicology, R. Justin Bingham
Causes, Extent, And Consequences Of Lead-Pellet Ingestion By Chukars (Alectoris Chukar) In Western Utah: Examining Habitat, Search Images, And Toxicology, R. Justin Bingham
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Lead ingestion adversely affects humans and over 130 species of wildlife. Wild chukars (Alectoris chukar) are documented to ingest lead, but the causes and consequences of this ingestion are poorly understood. The objectives of this research were to 1) examine the influence of habitat use, the hunting season, and seasonal climate on the extent and severity of lead ingestion by chukars in western Utah, 2) assess the effects of habitat use, feeding behaviors, and lead density on the causes of lead-pellet ingestion in captive and wild chukars, and 3) investigate the consequences of lead-pellet ingestion in captive chukars as a …
