Aim The Rosalia longicorn ( Rosalia alpina ) is an internationally protected icon of biodiversity associated with old trees and dead wood. Although the beetle regularly exploits several marginal hosts, its preferred main host is European beech ( Fagus sylvatica s.l.). Moreover, the geographical ranges of R. alpina and beech closely overlap. To assess whether their spatial association is mirrored in the genetic patterns of both...

Rising atmospheric CO 2 concentration ([ CO 2 ]) and attendant increases in growing season temperature are expected to be the most important global change factors impacting production agriculture. Although maize is the most highly produced crop worldwide, few studies have evaluated the interactive effects of elevated [ CO 2 ] and temperature on its photosynthetic physiology, agronomic traits or biomass, and seed yield under op...

Heat waves already have a large impact on crops and are predicted to become more intense and more frequent in the future. In this study, heat waves were imposed on soybean using infrared heating technology in a fully open‐air field experiment. Five separate heat waves were applied to field‐grown soybean ( Glycine max ) in central Illinois, three in 2010 and two in 2011. Thirty years of historical weather data from Illinois wer...
