Its diverse disciplinary communities, exemplified by the recently established ISMIR conference series, have yet to articulate a common research agenda or agree on methodological principles and(More)
Soil amendment with pyrogenic carbon (biochar) is discussed as strategy to improve soil fertility to enable economic plus environmental benefits. In temperate soils, however, the use of pure biochar mostly has moderately-negative to -positive yield effects. Here we demonstrate that co-composting considerably promoted biochars' positive effects, largely by(More)
Four cultivars of winter barley (Hordeum vulgare L.) and two cultivars of combining pea (Pisum sativum L.) were grown in the field in the UK (52° N) and irradiated under banks of UV-B lamps in 1994}95 (barley) and 1996 (pea). Supplementary UV-B radiation was applied to treated plots as a proportional addition to the UV-B dose received under a control plot.(More)
Question: Do anthropogenic disturbances interact with local environmental factors to increase the abundance and frequency of invasive species, which in tum exerts a negative effect on native biodiversity? Location: Mature Quercus-Carya and Quercus-Carya-Pinus (oak-hickory-pine) forests in north Mississippi, USA. Methods: We used partial correlation and(More)
