Carbon monoxide (CO), one of the most important prevalent trace gases in the troposphere, controls the oxidizing capacity of the atmosphere. In this project, whole air samples were collected quarterly (March, June, September and December) in the remote Pacific basin during 1995–…

Louping ill virus (LIV) is a tick borne disease that causes mortality in red grouse, an economically important game bird of British uplands. The aim of this thesis is to extend previously published models of LIV , to consider the potential impact of different management strategi…
Animal community structures, life histories and individual foraging behaviour are all an outcome of a trade-off between competition for resources (and thus the risk of starvation) and survival (and thus the risk of predation). The relative importance of these factors however, di…
This study involves the investigation of seasonality of death at Kellis 2 cemetery (c. AD 50-450), Dakhleh Oasis, Egypt, using solar alignment analysis of graves in conjunction with stable carbon and nitrogen isotope analysis of naturally mummified tissues. The hypothesis that t…
This dissertation examines overreaction, seasonality, and relationship among Middle East and North Africa (MENA) stock markets. The dissertation is organized in five chapters. The first chapter is introduction to the dissertation and its importance. The second chapter will discu…
Pogonomyrmex badius is understood as an ecosystem engineer due to its alteration of soil chemistry, seed dispersal, and seed predation. Because of its impressive role in the environment, life history traits of P. badius have been well studied. One trait that has yet to be studie…
For many species, life history events are cyclical and often correspond to specific environmental conditions. As a result of environmental variability, the optimal conditions that regulate the range and activity of highly regulated cyclical organisms, like cicadas, are subject t…
Later Glades-period cultures (ca. 500–1760 CE) of south Florida and the Florida Keys are understudied and thus poorly understood, especially those that pre-date the arrival of Spaniards to the New World. Recent archaeological models of their sociopolitical organization suggest t…
Seasonality is one of the most important sources of environmental variation that organisms face. In response, species have evolved a wide array of adaptive mechanisms to accommodate the cyclical fluctuations in, for example, temperatures, precipitation, biomass, food resources, …
