Factors Influencing Swallow Bug (O. Vicarius) Populations Within Cliff Swallows Nests, Paul Mcphail
Factors Influencing Swallow Bug (O. Vicarius) Populations Within Cliff Swallows Nests, Paul Mcphail
Ursidae: The Undergraduate Research Journal at the University of Northern Colorado
Hematophagous ectoparasites such as swallow bugs (Oeciacus vicarius) have been shown to have a profound negative impact on infested bird chicks, and one study shows that O. vicarius populations are positively correlated with large colonies. In this study, we investigated the abundance of O. vicarius and other arthropods within Cliff Swallow nests, and performed statistical analysis of the results to find any variables that correlated with O. vicarius population size. We expected the number of O. vicarius would be positively influenced by urban surroundings and large Cliff Swallow colony size, and that samples collected in the fall would be larger …
Joint Action Effects Of Emamectin Benzoate And Cypermethrin On The Marine Copepod Tigriopus Californicus, Lindsay Schultz, Michael Kelly
Joint Action Effects Of Emamectin Benzoate And Cypermethrin On The Marine Copepod Tigriopus Californicus, Lindsay Schultz, Michael Kelly
Ursidae: The Undergraduate Research Journal at the University of Northern Colorado
This project examined the effect of two pesticides on the marine copepod Tigriopus californicus. The pesticides are emamectin benzoate and cypermethrin, which are commonly used in salmon aquaculture to treat the salmon for sea lice, a type of parasitic copepod. The results of this study indicate that these pesticides are toxic to the free-living T. californicus at very low dosage levels when used individually. When the pesticides are used in combination, the mortality rate is similar to when they are used individually, but there is an additional paralytic effect on the animals. All animals exposed to any of the pesticide …
Dominance Hierarchies In Horses: Comparing And Contrasting Different Methods For Assessing Hierarchies, Devyn Bailey
Dominance Hierarchies In Horses: Comparing And Contrasting Different Methods For Assessing Hierarchies, Devyn Bailey
Ursidae: The Undergraduate Research Journal at the University of Northern Colorado
Understanding animal social structures is imperative when it comes to the care, housing and handling of large herd animals. Knowing how hierarchies are structured, along with environmental and physiological aspects that may affect them, will allow owners and breeders to house and care for their animals. The aim of my study was to better understand two methods used to assess dominance hierarchies in horses, Equus caballus, and to predict which method would be more useful for owners housing domestic horses. I designed an experiment where I compared a structured method, the paired feeding test, with behavioral observations from the …
