Benefits and risks of traditional food for indigenous peoples - Focus on dietary intakes of Arctic men

A variety of community and external pressures on Indigenous Peoples are leading to increased use of food that is available through industrialization and market economies; food in traditional food systems derived from local, natural environments is declining in use. This report focusses on dietary intake of Arctic men. While nutrient density of Arctic traditional food systems is superior to that of the composite of market food consumed in the North, the percentage of men's daily energy derived from market food is more than double that from traditional food in some communities. Older members of communities consume more traditional food than younger members; men consume more traditional food than do women. In addition...

Behavioural and environmental correlates of soaring-bird mortality at on-shore wind turbines

1. Wind power plants represent a risk of bird mortality, but the effects are still poorly quantified. We measured bird mortality, analysed the factors that led birds to fly close to turbines, and proposed mitigation measures at two wind farms installed in the Straits of Gibraltar, one of the most important migration bottlenecks between Europe and Africa. 2. Bird corpses were surveyed along turbine lines and an associated power line to estimate mortality rates. The behaviour of birds observed within 250 m of turbines was also recorded as a putative indicator of risk. The effects of location, weather and flight behaviour on risk situations (passes within 5 m of turbines) were analysed using generalized linear modelling...
