The purpose of this research is to apply visitor employed photography (VEP) to recreation management to develop indicators of the wildlife viewing experience. VEP and semi-structured interviews were used at a popular polar bear viewing destination in the Arctic National Wildlife Refuge (Arctic Refuge). Visitors to the Arctic Refuge who participated in an on-site semi-structured interview were asked to participate in a VEP procedure after their visit. A sample of 24 semi-structured interviews, and 17 VEP responses were collected and compared to test the utility of VEP to develop indicators of the wildlife viewing experience. Results indicate that VEP offers additional and unique types of information from semi-structured interviews for identifying indicators of the wildlife viewing experience. Potential indicators that emerged from VEP include 'time spent on the water viewing polar bears', and the 'number of vessels in view.' Indicators emerged exclusively from the VEP procedure, demonstrating the utility of VEP for recreation management and scientific inquiry.

Background: Cadmium (Cd) is a toxic heavy metal present in environment that has potential to instigate renal toxicity. Didymin (DDM) is a natural flavone, which shows anti-oxidant, anti-inflammatory and antiapoptotic nature. Therefore, the current study was formulated to appraise attenuative potential of DDM against Cd instigated nephrotoxicity.

Natural aging is associated with mild memory loss and cognitive decline, and age is the greatest risk factor for neurodegenerative diseases, such as Alzheimer's disease. There is substantial evidence that oxidative stress is a major contributor to both natural aging and neurodegenerative disease, and coincidently, levels of redox active metals such as Fe and Cu are known to be elevated later in life. Recently, a pronounced age-related increase in Cu content has been reported to occur in mice and rats around a vital regulatory brain region, the subventricular zone of lateral ventricles.

Predicting the spatial and temporal responses of species exhibiting intraguild predation (IGP) relationships is difficult due to variation in potential interactions and environmental context. Eurasian badgers () are intraguild predators of European hedgehogs () and are implicated in their population decline via both direct predation and competition for shared food resources. Previous studies have shown spatial separation between these species and attributed this to hedgehogs experiencing a 'landscape of fear', but little is known about the potential role of differential habitat use.
