    This thesis draws on five disparate data sources to examine availability and efficacy of media covering environmental risk in North Carolina. Framed as a study of environmental in/justice, the analysis uses objective measures of risk to examine the state's health disparities in light of demographic data. The results indicate that counties with more poor and more minority residents are both less healthy overall and have fewer media outlets to learn about health and environmental risks. Recommendations for more robust and thorough media coverage of environmental risks accompany suggestions for public health practitioners and future research

    Do Queens of Bumblebee Species Differ In Their Choice Of Flower Colour Morphs Of Corydalis Cava (Fumariaceae)?

    International audienceAbstractBumblebee queens require a continuous supply of flowering food plants from early spring for the successful development of annual colonies. Early in spring, Corydalis cava provides essential nectar and pollen resources and a choice of flower colour. In this paper, we examine flower colour choice (purple or white) in C. cava and verify the hypothesis that bumblebee queens differ in their choice of flower colour. A total of 10,615 observations of flower visits were made in spring 2011 and spring 2014 near Poznań, western Poland. Our results suggest that Bombus lucorum/cryptarum used purple flowers less, while Bombus terrestris used purple flowers more and Bombus hortorum showed no preference. Therefore, the colour morphs of C. cava are probably co-evolutionary adaptations to the development of another part of the insect community which has different colour preferences
