Interactions between tree species and their effects on nitrogen and phosphorus transformations in tMixed conifer plantations are less complex, but provide an opportunity to study interactions that may occur between tree species. Plantations of conifers in Britain have been mainly of single species unless there have been good reasons for planting mixtures. An example of this includes the increasin

Ground beetles in a changing environment: determinants of species diversity and community assembly,an the rate at which new species are formed (May 1988). The most direct cause of species extinction is the destruction of their habitat, but even in protected habitats indirect factors, notably atmospheric or water pollution and climate change, might lead to profound changes in plant and animal communities.
