Influenza A viruses (IAVs) belong to the family Orthomyxoviridae and represent major pathogens of both humans and animals. Swine influenza virus is an important pathogen that affects not only the swine industry, but also represents a constant threat to the turkey industry and is…
Analytical models of avian flight have previously been used to predict mechanical and metabolic power consumption during cruise. These models are limited, in that they neglect details of wing kinematics, and model power by assuming a fixed or rotary wing (actuator disk) weight s…
Comparatively little is known about the ability of commercially raised poultry and gamebirds to metabolize therapeutic drugs. The goal of this research was to use a combination of in vitro, in vivo and physiologically-based pharmacokinetic (PBPK) studies to characterize metaboli…
In 2001, a federal program, the Conservation Reserve Enhancement Program (CREP), was initiated in 20 counties in south-central Pennsylvania to address soil erosion and water quality with an expected secondary benefit of providing habitat for wildlife. Because of the decline in g…
Considerable progress has been made in mammalian species since the advent of <i>in vitro</i> sperm-egg interaction systems. Although <i>in vitro </i>systems for studying sperm-egg interaction in chickens have been developed, they have not been characterised and are limited by th…
Avian pathogenic strains of Escherichia coli serotypes O2, O35 and O78 cause air sac infections in turkeys, but the reason for the colonization of these serotypes is unknown. Air sac surface fluid (ASSF) from 8–12 weeks old turkeys was examined to identify proteins that bind sur…
Island archipelagos provide natural laboratories to investigate how geographical and ecological differences impact the process of speciation. I investigated the evolutionary history of four different bird species complexes distributed throughout the southwest Pacific. Within the…
Phylogeography combines geographic information with phylogenetic analysis to gain insight into the origin, dispersal, and speciation dynamics of populations. Advances in the utility of Next Generation Sequencing technology has led to a shift toward whole genome sequencing for an…
