Laboratory of Lichenology carries out research in the field of taxonomy (including chemotaxonomy and molecular variation), phylogeny, diversity, distribution and ecology of selected groups of lichens. Its scientific activity includes also issues related to the dynamics of changes in biota of lichens as well as problems of threat factors and conservation. The most intensive studies are being conducted in Europe and South America. North America, Asia, and the polar regions remain also within the scope of research. In addition, the Laboratory manage an extensive and considerably diverse (both taxonomically and geographically) lichen herbarium (KRAM-L), which is being constantly enriched by research documenting materials and collections obtained through scientific exchange.

CURRENT RESEARCH ACTIVITIES

Taxonomy of lichens, including chemotaxonomy, genetic variation and phylogeny of selected genera (Lecanora, Caloplaca, Umbilicaria and Verrucaria s.l.) and biological groups of lichens (foliicolous, lichenicolous and sterile lichens).

Diversity of South American lichens and lichenicolous fungi: 1) taxonomy, diversity and distribution of
foliicolous lichens; 2) taxonomy, ecology and distribution of lichens of the families Lecanoraceae, Parmeliaceae, Stereocaulaceae, Umbilicariaceae and Teloschistaceae; 3) chemistry of lichens in tropical and subtropical areas, with particular emphasis on sterile taxa; 4) inventory of lichens and lichenicolous fungi of various regions of Bolivia.

Taxonomy and distribution of lichens from the Arctic (Spitsbergen) and Antarctica (King George Island, Victoria Land) and of selected ecosystems in North America (e.g. Great Lakes lowland forest, Sonoran Desert) and Asia (e.g. mountains of Mongolia).

Lichen biota of Poland: 1) taxonomic revision of critical groups (genera Caloplaca, Lecanora, Verrucaria s.l., lichenicolous fungi); 2) diversity and conservation status in the Carpathian Mountains, particularly their foothills and the Tatra Mts.; 3) rare, endangered and protected species; 4) biota of protected areas (national parks, landscape parks, nature reserves).

Impact of human activity on the lichen biota: 1) diversity of lichens (especially in mountain glades and rock outcrops), depending on land use and/or conservation status; 2) bioindication value of lichens with particular reference to freshwater species.
