Dr. Jan Hackel

My research area is evolutionary biogeography: I want to understand how patterns of distribution were shaped by speciation, extinction and dispersal. I use field expeditions, molecular lab work and modelling to study these processes. My focus is on plants and fungi.

Research priorities

Grasses and grasslands

Grasses (family Poaceae) dominate roughly 40% of global land surface. I have worked, among other things, on the origins of grasslands in Madagascar. Currently, I continue work on the grasses on Madagascar and on phylogenomics of the grass family.

Macroevolutionary processes

Distribution patterns emerge through speciation, extinction and dispersal. These macroevolutionary processes can be reconstructed using phylogenetic trees. I am interested in particular in the factors affecting the dispersal of lineages.

Plant-symbiotic fungi

Close symbiotic relationships between plants and fungi are of biogeographic interest as the distribution of both partners is interdependent. I have worked on the biogeography of ectomycorrhizal fungi in the Neotropics. I am also interested in fungal endophytes of grasses.
