... and parasites during cleaning interactions, have rarely been evaluated. Here, we investigated whether the dedicated bluestreak cleaner wrasse, Labroides dimidiatus , is susceptible to and can transmit generalist ectoparasites between client fish. In laboratory experiments, L. dimidiatus were exposed...

...Zoë Langlands; Esther E. du Rand; Karl Crailsheim; Abdullahi A. Yusuf; Christian W. W. Pirk ABSTRACT The honeybee nest parasite Aethina tumida (small hive beetle) uses behavioural mimicry to induce trophallactic feeding from its honeybee hosts. Small hive beetles are able to induce honeybee workers...

... damage caused by this invasive parasite is well studied through the use of quantifiable gross pathological indices, providing a good measure of the swimbladder health status, they cannot separate the role of mechanical and morphological damage. Our study examined the appropriateness of three commonly...

... related to the principal host. Fleas parasitizing multiple host species might compensate for developmental instability when utilizing a novel host species; therefore, host-switching events in host-specific parasites could be constrained by the relatedness between a novel and a principal host species...

...Lucie Grécias; François Olivier Hébert; Chloé Suzanne Berger; Iain Barber; Nadia Aubin-Horth ABSTRACT Sticklebacks infected by the parasitic flatworm Schistocephalus solidus show dramatic changes in phenotype, including a loss of species-typical behavioural responses to predators. The timing...

... instead of dispersing them. Feeding behaviour Nutrient Parasite Mutualism Fig-eating bat Around 550 plant species in the Neotropics have so far been found to depend on bats as seed dispersers ( Lobova et al., 2009 ). In this mutualistic relationship, bats obtain nutrients from fruits...

...Frank Cézilly; Adrien Favrat; Marie-Jeanne Perrot-Minnot Summary In most cases, parasites alter more than one dimension in their host phenotype. Although multidimensionality in parasite-induced phenotypic alterations (PIPAs) seems to be the rule, it has started to be addressed only recently. Here...

...Glenn A. McConkey; Heather L. Martin; Greg C. Bristow; Joanne P. Webster Summary Parasite location has been proposed as an important factor in the behavioural changes observed in rodents infected with the protozoan Toxoplasma gondii . During the chronic stages of infection, encysted parasites...

...Jaroslav Flegr Summary The parasitic protozoan Toxoplasma gondii infects about one-third of the population of developed countries. The life-long presence of dormant stages of this parasite in the brain and muscular tissues of infected humans is usually considered asymptomatic from the clinical...

...David Hughes Summary The study of the adaptive manipulation of animal behavior by parasites is entering very exciting times. Collectively the field has moved from its important and instructional natural history phase into proximate-level studies aiming to elucidate the mechanisms by which one...

... increases in disease, including those of medical and veterinary importance. While this work has focused primarily on correlational studies involving vector-borne microparasite diseases (e.g. Lyme disease, West Nile virus), we argue that parasites with complex life cycles (e.g. helminths, protists...

...A. J. Pruijssers; P. Falabella; J. H. Eum; F. Pennacchio; M. R. Brown; M. R. Strand SUMMARY Insect pathogens and parasites often affect the growth and development of their hosts, but understanding of these processes is fragmentary. Among the most species-rich and important mortality agents...

...Geoffrey E. Hill; Kristy L. Farmer; Michelle L. Beck SUMMARY Parasites are widely assumed to cause reduced expression of ornamental plumage coloration, but few experimental studies have tested this hypothesis. We captured young male house finches Carpodacus mexicanus in Alabama before fall molt...

...S. N. Thompson; R. A. Redak; L.-W. Wang SUMMARY Manduca sexta larvae exhibited altered food selection over a 2- or 3-day feeding period when parasitized by Cotesia congregata , and offered a choice of two chemically defined diets, one containing casein without sucrose and a second with sucrose...

... hearing is mediated by intertympanal mechanical coupling, a process that amplifies small acoustic cues into significant interaural time and amplitude differences ( Miles et al., 1995 ; Robert et al., 1996 ; Robert and Hoy, 1998 ). acoustics directional hearing orientation Diptera parasite...

We discuss possible explanations for the co-occurrence of high haemolymph octopamine levels and low behavioural arousal in parasitized M. sexta . References Adamo , S. A. ( 1997...
