ALTERED PREDATION SUSCEPTIBILITY OF MOSQUITOFISH INFECTED WITH EUSTRONGYLIDES IGNOTUS

Altered Behavior of Parasitized Killifish Increases Susceptibility to Predation by Bird Final Hosts

Parasites that are transmitted from prey to predator are often associated with altered prey behavior. Although many concur that behavior modification is a parasite strategy that facilitates transmission by making parasitized prey easier for predators to capture, there is little evidence from field experiments. We observed that conspicuous behaviors exhibited by killifish (Fundulus parvipinnis) ...

Effects of a parasitic nematode on male mate choice in a livebearing fish with a coercive mating system (western mosquitofish, Gambusia affinis).

I examined the effects of the parasitic larval nematode, Eustrongylides ignotus, on male mate choice in the western mosquitofish, Gambusia affinis. I hypothesized that parasite presence influences male mate choice either directly (via reduction in male mating behavior due to presence of parasite in females) or indirectly (via reduction in male mating behavior due to reduced condition of infecte...

Effects of Size and Exposure to Predation Threat on Mating Behavior and Predation Response in Male Western Mosquitofish (gambusia Affinis)

Altered Immune Responses and Susceptibility

Susceptibility of Select Agents to Predation by Predatory Bacteria

Select Agents are microorganisms and toxins considered to be exploitable as biological weapons. Although infections by many Select Agents can be treated by conventional antibiotics, the risk of an emerging or engineered drug resistant strain is of great concern. One group of microorganisms that is showing potential to control drug resistant Gram-negative bacteria are the predatory bacteria from...
