Evidence for carry-over effects of predator exposure on pathogen transmission potential.
Accumulating evidence indicates that species interactions such as competition and predation can indirectly alter interactions with other community members, including parasites. For example, presence of predators can induce behavioural defences in the prey, resulting in a change in susceptibility to parasites. Such predator-induced phenotypic changes may be especially pervasive in prey with disc...
متن کاملCarry-over effects of smoking cue exposure on working memory performance.
The present study investigated the effects of drug cue exposure on working memory performance in cigarette smokers. Adult smokers (N = 23) deprived for 12 hr performed a working memory task during which they were exposed to three types of task-irrelevant stimuli: Pictures containing smoking related-content, pictures devoid of smoking content, and a fixation cross. Consistent with prior research...
متن کاملFungal pathogen reduces potential for malaria transmission.
Using a rodent malaria model, we found that exposure to surfaces treated with fungal entomopathogens following an infectious blood meal reduced the number of mosquitoes able to transmit malaria by a factor of about 80. Fungal infection, achieved through contact with both solid surfaces and netting for durations well within the typical post-feed resting periods, was sufficient to cause >90% mort...
متن کاملRecommendations for definition and determination of carry-over effects
The term ’carry-over’ is commonly used to describe a process by which materials are carried into a reaction mixture to which they do not belong. These materials can be either parts of a specimen or reagents, including diluent or wash solution. In such cases carry-over means transfer of material (specimen or reagents) from one container or from one reaction mixture to another; it can be either u...
متن کاملPredicting the consequences of carry-over effects for migratory populations.
Migratory animals present a unique challenge for predicting population size because they are influenced by events in multiple stages of the annual cycle that are separated by large geographic distances. Here, we develop a model that incorporates non-fatal carry-over effects to predict changes in population size and show how this can be integrated with predictive models of habitat loss and deter...
