MICROARTHROPODS IN URBAN SISTEMS
The soil microarthropod fauna was studicd in the urban park Balmaceda, in Santiago, Chile.A total of 61 samples were taken under five contrasting situations, namely grass (formed by acomplex of species), a shrubby plant Ligusirum sinensis and three species of tree namely,Cryptocarya alba, Quercus sú...
