Anna-Liisa Ylisirniö has a background in population biology and ecology, her current research focusing on biodiversity in boreal forest ecosystems. Her ongoing projects investigate the effects of different forest management methods on diversity of saproxylic species, especially the effects of new forest management methods on species diversity of wood-decomposing fungi and epiphytic lichens. She has also studied e.g. land use conflicts in northern regions.
