Examples of behavioural manipulation by parasites are numerous, but the processes underlying these changes are not well characterized. From an evolutionary point of view, behavioural changes in infected hosts have often been interpreted as illustrations of the extended phenotype concept, in which genes in one organism (the parasite) have phenotypic effects(More)
Behavioural fever, defined as an acute change in thermal preference driven by pathogen recognition, has been reported in a variety of invertebrates and ectothermic vertebrates. It has been suggested, but so far not confirmed, that such changes in thermal regime favour the immune response and thus promote survival. Here, we show that zebrafish display(More)

Biting fly behavior involved in parasite transmission is reviewed. Except for the areas of activity and probing, few investigations have addressed ways in which parasites might alter vector behavior. Given the manner in which parasites alter behavior in other arthropods (e.g., habitat choice, color preference), it is reasonable to expect infected(More)
Moniliformis moniliformis-infected Periplaneta australasiae and Blatta orientalis were less active than uninfected controls in behavioral arena tests under both red and white light regimes. There was a strong interaction between light regime and parasitism for substrate use by P. australasiae. Under red light, parasitism decreased the use of black(More)
Adult acanthocephalan body sizes vary interspecifically over more than two orders of magnitude; yet, despite its importance for our understanding of the coevolutionary links between hosts and parasites, this variation remains unexplained. Here, we used a comparative analysis to investigate how final adult sizes and relative increments in size following(More)
We examined behavioral alterations in the brown cockroach, Periplaneta brunnea, infected with the acanthocephalan, Moniliformis moniliformis. The responses of infected and uninfected P. brunnea to light, substrate choice, and activity were compared. Infected brown cockroaches spent more time on white horizontal substrates under red and white light. Infected(More)
PURPOSE The purpose of this study was to test the hypothesis that exposure to a directly transmitted human pathogen-flu virus-increases human social behavior presymptomatically. This hypothesis is grounded in empirical evidence that animals infected with pathogens rarely behave like uninfected animals, and in evolutionary theory as applied to infectious(More)
The 3 rd Annual Non-Volatile Memories Workshop (NVMW 2012) provides a unique showcase for outstanding research on solid state, non-volatile memories. It features a " vertically integrated " program that includes presentations on devices, data encoding, systems architecture, and applications related to these exciting new data storage technologies.
