OBJECTIVE Stressful events enhance risk for weight gain and adiposity. Ghrelin and leptin, two hormones that are implicated in appetite regulation, may link stressful events to weight gain; a number of rodent studies suggest that stressors increase ghrelin production. The present study investigated the links among daily stressors, ghrelin and leptin, and dietary intake in humans. METHOD Women...

The Etowah River basin in Georgia, USA, supports nine imperiled fish species that are the object of protection under the proposed Etowah Habitat Conservation Plan (HCP). With urban land cover steadily increasing in the basin at the expense of forest and agricultural land cover, development-related activities and their consequences appear, as a group, to be the major threat to the species. Howev...

Concern is growing about the potential effects of interacting multiple stressors, especially as the global climate changes. We provide a comprehensive review of multiple stressor interactions in coral reef ecosystems, which are widely considered to be one of the most sensitive ecosystems to global change. First, we synthesized coral reef studies that examined interactions of two or more stresso...

Understanding the response of organisms to multiple stressors is critical for predicting if populations can adapt to rapid environmental change. Natural and anthropogenic stressors often interact, complicating general predictions. In this study, we examined the interactive and cumulative effects of two common environmental stressors, lowered calcium concentration, an anthropogenic stressor, and...

Introduction Harmful alcohol use has been found to cause detriment to the consumers and those around them. Research carried out in Sri Lanka has described the socioeconomic consequences to families owing to alcohol consumption. However, the social processes around alcohol use and how it could result in behaviour such as self-harm was unclear. With an outset in daily life stressors in marriages ...

Laboratory studies of stress and memory have generally found that people with more stress tend to have poorer cognitive performance. The present investigation examined the relationship between stressors and memory failures in a naturalistic setting via a daily diary study of 333 older adults in the VA Normative Aging Study. Multilevel models indicated that on days when people experienced stress...

BACKGROUND High levels of stress among ambulance personnel have been attributed to the conditions of ambulance work. However, there is little research to support this notion, and it has been questioned whether ambulance work is inherently stressful. We compared the severity and frequency level of organizational and ambulance-specific stressors, and studied their relationship to organizational c...

The effects of stress on memory are typically assessed individually; however, in reality different stressors are often experienced simultaneously. Here we determined the effect that two environmentally relevant stressors, crowding and low calcium availability, have on memory and neural activity following operant conditioning of aerial respiration in the pond snail, Lymnaea stagnalis. We measure...
