Abstract:
... Kochia [Bassia scoparia (L.) A.J. Scott] is a problematic summer-annual tumbleweed that infests cropped and noncropped areas in the Great Plains of North America. Efficient seed dispersal, prolific seed production, and abiotic stress tolerance facilitate invasiveness of kochia, while both resource-limiting and non-resource-limiting interference aid in rapid colonization of disturbed areas. Resista ...

Abstract:
... Intensive cereal monoculture is currently the main cause of biodiversity decline in Europe. However, it is difficult to disentangle the effects of intensive monoculture (e.g. pesticide use, mechanical ploughing and reduced protective cover), let alone evaluate how far the reduction of crop diversity affects biodiversity. It remains unclear to which extent the consequent decrease in food resources ...

Abstract:
... Mediterranean cropping systems in rainfed conditions are generally based on rotations with a very high frequency of winter wheat and, therefore, they are at risk of declining trends for yield and soil health in the long-term. In order to quantify this risk, a long-term experiment was set-up in 1971 in central Italy, which is still running at present (2016). This experiment is based on 13 rotations ...
