Ecosystem-level effects of stressors are critical to understanding community regulation, and environmental stress models are useful in describing such effects. Hypoxia is an important stressor in aquatic ecosystems that usually decreases abundance and biomass of benthic fauna. In field surveys, predator abundance is low in hypoxic areas, and in lab experiments, predators reduce their feeding ra...

Post‑traumatic stress disorder (PTSD) is an anxiety disorder triggered by life‑threatening events that cause intense fear. Exercise is known to have protective effects on neuropsychiatric diseases. The present study investigated whether treadmill exercise during pregnancy reduced or alleviated symptoms of PTSD in maternal rats. To induce predator stress in pregnant rats, rats were exposed to a ...

Cyber-crime targeting children such as online pedophile activity are a major and a growing concern to the society. A deep understanding of predatory chat conversations on the Internet has implications in designing effective solutions to automatically identify malicious conversations from regular conversations. We believe that a deeper understanding of the pedophile conversation can result in mo...

This study assessed middle and high school students’ knowledge of potential risks, appropriate use, and their behaviours on the internet and social networking sites, especially regarding behaviours that may lead to cyber bullying or contact with potential internet predators. A total of N = 4,215 middle and high school students were assessed in a northeast state using the 47 items and five dimen...

As climate regimes shift in many ecosystems worldwide, evolution may be a critical process allowing persistence in rapidly changing environments. Organisms regularly interact with other species, yet whether climate-mediated evolution can occur in the context of species interactions is not well understood. We tested whether a species interaction could modify evolutionary responses to temperature...

Tame behaviour, i.e. low wariness, in terrestrial island species is often attributed to low predation pressure. However, we know little about its physiological control and its flexibility in the face of predator introductions. Marine iguanas (Amblyrhynchus cristatus) on the Galapagos Islands are a good model to study the physiological correlates of low wariness. They have lived virtually withou...
