Adam Flakus joined the W. Szafer Institute of Botany PAS in 2003 as a PhD student, focusing on the ecology and systematics of lichen-forming fungi in the highest vegetation belt in the Carpathians. From 2008 to 2019, he worked as assistant professor, and in 2019 also as a lichen curator at KRAM. In 2020 he became Professor. Currently he studies the evolution of symbiotic systems involving fungi, algae and cyanobacteria in tropical ecosystems, especially in Bolivia. He is particularly interested in the lichen-associated microbiome and the evolutionary outcomes of these symbioses.

 

Research interests:

Lichenology, molecular evolution, symbiotic relationships, systematics, fungal parasites.

Anna Ronikier is a mycologist working at the W. Szafer Institute of Botany PAS since 2000. Her research is focused on two areas: (1) taxonomy and biogeography of macrofungi with a special interest in species of arctic and alpine ecosystems, (2) taxonomy and biogeography of myxomycetes – a specialized group of fungal-like organisms. She is particularly interested in discovering worldwide biogeographical patterns of nivicolous myxomycetes, an ecological group associated with mountain areas and potentially important as biotic indicators of climate-driven changes in the extent and duration of winter snow cover. She works in various mountain ranges, but with a special focus on the Andes. In her recent work, she combines critical assessment of morphological features with phylogenetic approaches, develops molecular biogeography of nivicolous myxomycetes and conducts metabarcoding studies of myxomycete communities in mountainous and polar areas.

 

Research interests:

Arctic-alpine fungi, biogeography, nivicolous myxomycetes, phylogeography, taxonomy and nomenclature.

Michał Ronikier is employed at the W. Szafer Institute of Botany PAS, where he earned his PhD (2005) and DSc (habilitation) (2014). Currently, he heads the Laboratory of Molecular Analyses and leads his own research group. He is a botanist and biogeographer, particularly interested in studying the structure and patterns of biodiversity and the dynamics of their changes in time and space, with the disjunctively distributed cold-adapted (high-mountain and polar) biota as a main model. He applies the latest molecular tools to unravel patterns of genetic diversity and divergence in cold-adapted organisms, understand the evolutionary processes shaping their historical biogeography and forecast potential scenarios of species’ response to ongoing climate changes. In his current work, he explores such approaches as comparative phylogeography and next-generation sequencing including museum genomics (museomics) and metabarcoding of environmental DNA, to extend sources of available biogeographical information.

 

Research interests:

Biodiversity, biogeography, evolution, phylogeography, alpine and polar biota.
