Behavioral Responses Of Willow Flycatchers, Empidonax Traillii, To A Heterogeneous Environment, Amanda V. Bakian
Behavioral Responses Of Willow Flycatchers, Empidonax Traillii, To A Heterogeneous Environment, Amanda V. Bakian
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Spatial heterogeneity impacts population and community-level dynamics including species-level dispersal patterns, the use and availability of refugia, predator/prey dynamics, and reproductive fitness. Understanding how wild animal populations respond to environmental heterogeneity is essential for their proper management and conservation. In this study, I examine the responses of Willow Flycatchers to spatial heterogeneity in the distribution of their food and habitat resources. Over the course of three breeding seasons, I radio- tracked Willow Flycatchers at Fish Creek in Manti-La Sal National Forest in Utah, recorded detailed behavior data at each radio location, and collected fecal, feather and insect samples. I formulated …
A Proposed Methodology For Predicting The Carbon And Nitrogen Stable Isotope Measures Of K'Inich Yax K'Uk Mo', Copan Dynastic Founder, Keith Edwards
A Proposed Methodology For Predicting The Carbon And Nitrogen Stable Isotope Measures Of K'Inich Yax K'Uk Mo', Copan Dynastic Founder, Keith Edwards
Electronic Theses and Dissertations
The purpose of this thesis is to show that stable isotope analysis can be used to predict K’inich Yax K’uk Mo’s stable isotope measures based on Stuart’s (2007) hypothesis that K’inich Yax K’uk Mo’, the dynastic founder of the Copan royal lineage, was a Caracol lord. There is significant and convincing evidence that K’inich Yak K’uk Mo’ had a non-Copanec origin. Stable isotope analysis is a tested and reliable method for detailing diets and migratory paths of ancient humans and this theory is applied as a predictor of the stable isotope measures of K’inich Yax K’uk Mo’, if he did …
Stable Carbon And Nitrogen Isotope Analyses Of Subfossil Rats From Liang Bua (Flores, Indonesia), Kelly C. Anderson
Stable Carbon And Nitrogen Isotope Analyses Of Subfossil Rats From Liang Bua (Flores, Indonesia), Kelly C. Anderson
Electronic Theses and Dissertations
This research study investigated the level of bone collagen preservation of rat femora from Liang Bua cave on the island of Flores, Indonesia, as well as conducted carbon and nitrogen stable isotopic analyses on well preserved samples. Although Flores is located in a hot intermediate tropical zone and the burial environment of the bone samples within the cave is considered less than optimal for collagen preservation, significant preservation of the bone collagen was found. Collagen yields, C:N ratio and carbon and nitrogen concentrations were investigated. However, this research study argues that carbon and nitrogen concentrations are an appropriate means to …
Palaeoclimatic Significance Of Perennial Ice Accumulations In Caves: An Example From Scarisoara Ice Cave, Romania, Aurel Persoiu Tiritu
Palaeoclimatic Significance Of Perennial Ice Accumulations In Caves: An Example From Scarisoara Ice Cave, Romania, Aurel Persoiu Tiritu
USF Tampa Graduate Theses and Dissertations
Stable isotopes in ice cores drilled in the polar and high-mountain region have been used intensively to reconstruct past climatic changes and atmospheric dynamics. However, no similar studies have been conducted on perennial ice accumulations in caves due to a limited understanding of the links between the external and cave environments, and the way in which the climatic signal can be recorded by the cave ice.
In this thesis, we successfully designed and build a research methodology for the reconstruction of past climatic changes based on perennial ice accumulation in caves, using as example the Scarisoara Ice Cave, Romania. The …
