The River Otter In Idaho: Reproductive And Population Parameters And Liver Concentrations Of Environmental Contaminants, Gina Diggs
Boise State University Theses and Dissertations
To obtain current data on the North American river otter (Lontra canadensis) population in Idaho, licensed trappers were mandated to surrender river otter carcasses through provisions of the Idaho Department of Fish and Game’s mandatory harvest report. Throughout the 2002-2003 and 2003-2004 trapping seasons, 237 river otter carcasses were collected. Necropsies were performed to assess age and sex, general body condition, reproductive rates, and concentrations of environmental contaminants in the livers. Reproductive rates were determined by counting corpora lutea and blastocysts in female river otters. Livers were dissected and concentrations of environmental contaminants were determined for the following …
Impacts Of Wind Energy Development On Breeding Buteo Hawks In The Columbia Plateau Ecoregion, Patrick Shea Kolar
Impacts Of Wind Energy Development On Breeding Buteo Hawks In The Columbia Plateau Ecoregion, Patrick Shea Kolar
Boise State University Theses and Dissertations
Post-construction raptor fatality and nest monitoring is typically conducted at wind energy projects nationwide. However, pre- and post-construction surveys may fail to locate all breeding pairs and most studies at individual wind projects lack the necessary sample size or survey design to assess the effects of turbines on nesting raptors after construction. To address these potential issues, I used an information-theoretic approach to examine the influence of multiple spatial and temporal variables on reproductive success, post-fledging survival, and the distribution of breeding pairs from three sympatric Buteo species in the Columbia Plateau Ecoregion (CPE). Although the probability of detecting breeding …
Evaluating The Effects Of Fungicides And Other Pesticides On Non-Target Gut Fungi And Their Aquatic Insect Hosts, Emma R. Wilson
Evaluating The Effects Of Fungicides And Other Pesticides On Non-Target Gut Fungi And Their Aquatic Insect Hosts, Emma R. Wilson
Boise State University Theses and Dissertations
Pesticides are widespread and have been long used to combat the attack and destruction of crops. Fungicides have been used to prevent the establishment of many fungal pathogens, yet little is known about the impacts of fungicides on non-target fungi. With these considerations, it was predicted that trichomycetes, or gut fungi, a group of symbiotic fungi associated with aquatic macroinvertebrates and other arthropods, might be a candidate system to study because of the intimate association with their hosts. Field and laboratory studies were initiated to assess non-target impacts of fungicides on gut fungi. Field surveys were conducted on four streams …
