Louis Mielke
As an ecologist and conservation biologist, I am interested in the coevality of carbon sequestration and biodiversity. My focus is on fungi because they are elusive yet ubiquitous and functionally diverse; this in turn, influences the break down and accumulation of organic matter differently. Ectomycorrhizal fungi are particularly of interest since they are a conduit for carbon allocation belowground from host trees and also are of conservation concern largely due to clear cutting of forest ecosystems.

Are current methods for evaluating forest conservational values, accurate, objective and cost-efficient? (FORMAS)

My focus on this project is to compare traditional aboveground conservation values in swedish forests with the number of ectomycorrhizal fungal species via soil DNA metabarcoding techniques. This will help inform forest companies, field consultants and the swedish government to make decisions on which forests to keep or cut, and really answer whether the methods currently used are good indicators for ectomycorrhizal fungal diversity.

Mechanistic understanding of the mycorrhizal fungal carbon sink of northern terrestrial ecosystems" testing the Gadgil and mycorrhizal trait hypotheses (VR).

Mycorrhizal fungi are a particularly interesting group in the context of forest management and climate change because they depend on recent photosynthates from plant hosts in exchange for water and other nutrients, and rapidly accumulate and release that carbon. This makes them integral part of soil organic matter accumulatiuon and degradation. I will be testing how the interactions of different organism groups (e.g. ectomycorrhizal fungal pine roots, ericaceous shrubs and saprotrophs) influence decomposition and soil respiration dynamics in a mature pine forest.


I am a PhD representative for the Focus on Soils and Water Research School, FOMAN and a department representative for the NJ-Faculty PhD Council.
