Summary1. There has been considerable debate over the past decade with respect to wildlife provisioning, especially resultant behavioural changes that may impact the ecological function of an apex predator. The controversy is exemplified by the shark diving industry, where major criticisms based on inference, anecdote and opinion stem from concerns of potential behaviourally mediated ecosystem effects because of ecotourism provisioning (aka 'chumming' or feeding).2. There is a general lack of empirical evidence to refute or support associated claims. The few studies that have investigated the behavioural impacts of shark provisioning ecotourism have generated conflicting conclusions, where the confidence in such results may suffer from a narrow spatial and temporal focus given the highly mobile nature of these predators. There is need for studies that examine the potential behavioural consequences of provisioning over ecologically relevant spatial and temporal scales. 3. To advance this debate, we conducted the first satellite telemetry study and movement analysis to explicitly examine the long-range migrations and habitat utilization of tiger sharks (Galeocerdo cuvier) originating in the Bahamas and Florida, two areas that differ significantly with regards to the presence ⁄ absence of provisioning ecotourism. 4. Satellite telemetry data rejected the behaviourally mediated effects of provisioning ecotourism at large spatial and temporal scales. In contrast, to the restricted activity space and movement that were hypothesized, geolocation data evidenced previously unknown long-distance migrations and habitat use for both tiger shark populations closely associated with areas of high biological productivity in the Gulf Stream and subtropical western Atlantic Ocean. We speculate that these areas are likely critically important for G. cuvier feeding forays and parturition. 5. We concluded that, in the light of potential conservation and public awareness benefits of ecotourism provisioning, this practice should not be dismissed out of hand by managers. Given the pressing need for improved understanding of the functional ecology of apex predators relative to human disturbance, empirical studies of different species sensitivities to disturbance should be used to guide best-practice ecotourism policies that maximize conservation goals.

Water recycling is increasingly recognized as a critical strategy to maintain sustainable water supplies. Yet public acceptance of water recycling often lags behind. It is unclear the degree to which individuals are aware of the role of disgust in their decisions about recycled water, how important anticipated disgust is to willingness to use when controlling for other factors, and what the most effective method of presenting information about water recycling would be to decrease disgust reactions and increase willingness to use. We used a two‐pronged approach, combining a survey with open‐ended and psychometric measures with an experimental manipulation, in a U.S., web‐based sample (N = 428). Only 2% of participants self‐identified disgust as important to their decisions about recycled water. When measured directly using a Likert scale, however, anticipated disgust was the strongest predictor of willingness to use recycled water when controlling for individual differences that have been shown to impact willingness to use, including a subscale of individual pathogen disgust sensitivity. Finally, participants were exposed to an educational brochure about water reuse framed either affectively or cognitively or were shown a simple, neutral definition. Exposure to either the affectively or cognitively framed brochures lowered anticipated disgust, but did not significantly affect willingness to use recycled water compared to the neutral condition.
