PhD position in soil ecology focusing on earthworms, soil microorganisms and carbon dynamics
Although earthworms are widely present in European forests, the northern regions of Scandinavia are still largely lacking burrowing earthworm species. The expansion of such species into northern forests may have dramatic effects on the capacity of these soils to store carbon. In addition to physical soil mixing, earthworms may have cascading effects on soil microorganisms that control decomposition and nitrogen availability. The aim of this project is to quantify the impacts of burrowing earthworm expansion on soil C and N cycling in Scandinavia’s northern forests, and the mechanisms by which earthworms affect soil processes. We will use controlled mesocosm experiments and identify current and historical invasion gradients using eDNA analysis of soils sampled across Sweden to quantify effects of earthworms on soil fungi and bacteria and C sequestration. This project will identify whether climate-driven expansion of burrowing earthworm species is a threat for C storage in northern forest soils.
The PhD student is expected to develop their thesis work within this project, supported by the main supervisor and a co-supervisors. Additionally the student will develop their academic skills by following PhD courses and be involved in teaching undergraduate students.
