Arctic warming and permafrost degradation are reshaping northern ecosystems by alteringmicrotopography, soil water dynamics, nutrient availability, and vegetation succession. These shifts invegetation composition and changes in soil physical and chemical conditions may influence mineralelement cycling by vegetation. This master's thesis aims to understand how plants cycle trace elementsacross different Arctic habitats. To investigate this, trace element concentrations in plants and soil areexamined for 2021 at two study sites in Abisko, Sweden: a peatland mire and a heathland. Within eachsite, three habitats are studied along gradients of abiotic conditions such as pH and soil moisture. Ninewidely distributed Arctic plant species with varying rooting depths are analyzed. Within a habitat, the orderof foliar element concentrations from most to least concentrated is Mn > Fe > Zn > Ti > Cu > Mo > V >Cd > As. The results demonstrate that foliar element concentrations varied across Arctic habitats due toseveral factors: soil properties, habitat floristic composition, and plant physiology. They also indicate thatvariations in soil concentrations or the floristic composition of the habitats alter the foliar concentrations,thereby impacting foliar stocks and fluxes. As Arctic warming modifies soil characteristics and the floristiccomposition of habitats, foliar element concentrations will be altered accordingly, modifying foliar stocksand fluxes.
