    Sammanfattning : Carex humilis forms rings of densely aggregated ramets in dry grassland vegetation in Central Europe. In the thesis I conclude that ramet demography is important both for analyzing fitness in clonal plants and for understanding how C. humilis rings are formed. I studied the ramet demography of C.

    Sammanfattning : This thesis is focused on naturally produced organohalogens in soil. It was long assumed that organohalogens found in the environment were mainly of anthropogenic origin, but recent research has shown that large amounts of naturally produced organohalogens are stored in terrestrial environments.
