… trees was significantly lower in the shelterwoods with dominant trees. The species composition in the field and bush layers varied greatly between the shelterwoods with dominant and co-dominant trees. Under the cover of the dominant trees there was hardly any bush layer whilst …

… genetic background, which is supported by observations on a number of other species. The results indicate that it may be possible to reduce the problem with oxidized flavour in milk through selection and thereby exceed the shelf life of dairy products.
… be favored by the changing climate are for example those which are C3-plants, species with invasive characters, grass weeds and perennial weeds. As a result of a warmer climate the climate zones will be moving up north and there is a risk that troublesome weeds immigrate to …
