A protozoan parasite weakens the stress reaction of monarch butterflies

Jovani Raya, a student from Abaraham Baldwin Agricultural College, worked with Dr. Sonia Altizer and Dr. Andy Davis to study the effect of infection on the stress reaction of monarch butterflies. Abstract:  The protozoan parasite Ophryocystis elektroscirrha (OE) affects the adult mortality, longevity, body size, and flight ability of monarch butterflies (Danaus plexippus). However, very

The Battle of the Sperm: Observations of Sperm Competition in a Wolbachia Infected Species

LaTrice Montgomery, a student from Hampton University, worked with Paul Ginsberg in the lab of Dr. Kelly Dyer to study sperm competition in an infected fly species. Abstract:  Wolbachia, a maternally inherited bacterium, is broadly distributed among arthropod hosts. It is also capable of reducing viral load in its host, preventing the transmission of human

How does overall population density and temperature affect the fecundity of female Aedes aegypti mosquitoes?

Lindsey Jones, a student from Albany State University, worked with Michelle Evans in the lab of Dr. Courtney Murdock to look at fecundity of a mosquito vector species. Abstract:  Dynamics of mosquito-borne diseases such as Zika, yellow fever, chikungunya, and dengue depend on the ecology of both the disease and vector. Past studies have shown

Role of the bsr gene in the Intracellular Survival of Bordetella bronchiseptica

Hira Hasan, a student from Louisiana State University, worked with Monica Cartelle-Gestal in the lab of Dr. Eric Harvell to study the intracellular survival of Bordetella bacteria. Abstract:  Bordetella pertussis and B. parapertussis are Gram-negative bacteria that cause a respiratory infection, known as whooping cough, in humans. Another member of the Bordetella species, B. bronchiseptica

Resource shifts and infectious disease dynamics in urbanized bird popualtions

Katie Adkins, a student from Clemson University, participated in an ongoing study of infectious disease dynamics in urban bird populations, supervised by Drs. Sonia Hernandez and Michael Yabsley. Many wildlife species benefit from novel resources – especially supplemental food – offered in human-altered habitats. Shifts in wildlife ecology in response to intentional or accidental feeding

Research and Design of Biomedical Telemetry Device using Light Transmission

Mauricio Gallegos, a student from Clemson University, along with Austin Mesa from Florida International University, worked in the lab of Dr. Juan Guttierrez to design an implantable biomedical sensor. Abstract: The goal of this project was to design and miniaturize an implantable biomedical telemetry sensor that provides continuous, long-term telemetry data that could, in turn,

Differences in age distribution patterns in urban and rural counties of São Paulo state, Brazil

Magdalene Walters, a student from the University of Notre Dame, worked with Dr. John Drake to study the age distribution of a measles outbreak. Abstract:  In 1997, São Paulo, Brazil experienced a measles outbreak with an unusually high average age of infection. It has since been hypothesized that this high age of infection was due

Pathogen co-infection patterns within domestic dogs in rural environments

Djion Holness, a student from the University of Connecticut, worked with Amaka Nina Ananaba in the lab of Dr. Nicole Gottdenker to examine pathogen co-infection in dogs. Abstract: Pathogens can interact with each other within a host, which can influence patterns of co-infection in populations by complex interactions within the host’s immune system, such as

Testing the Enemy Release Hypothesis in Ungulates (Artiodactyl and Perissodactyl) and Carnivores

Lauren Kleine, a student from Colorado State University, examined the enemy release hypothesis in a project directed by Dr. Patrick Stephens and Dr. J.P. Schmidt. Abstract:  The Enemy Release Hypothesis (ERH) predicts that invasive species will achieve greater success in non-native ranges due in part to escape from parasites found in their native ranges. The
