Research

Interests

My research interests are focussed on the ecology and evolution of amphibious lichens, bioindication and the conservation of lichenised fungi and their associated algae.

Projects

Evolution and taxonomy of amphibious lichens within the family Verrucariaceae (Ascomycota)

External collaborators: C Gueidan (Canberra, Asutralia), J Nascimbene, C Ruperti, F LoSchiavo (University Padua, Italy), S Heidmarsson (Icelandic Museum Natural History and University Akureyri, Iceland), A Orange (National Museum of Wales, Cardiff), J Pykälä (University Helsinki, Finland), S Perez-Ortega (Centro de Ciencias Medioambientales, Madrid, Spain), B Büdel (Technical University Kaiserslautern, Germany), M Hauck (University Göttingen, Germany).

Amphibious lineages have evolved several times independently in the lichen family Verrucariaceae (Ascomcyota). The aim of this project is to study within selected species groups, what distinguishes closely related taxa from amphibious and terrestrial habitats, with a focus on morphological and ecophysiological traits with the by-product of revisions for these taxonomically problematic species groups.

What makes the difference? Identifying Hot Spots of freshwater lichen biodiversity on different spatial scales

Collaborators: Juri Nascimbene (Padua, Italy), Matthias Schultz (Hamburg, Germany), Roman Türk (Salzburg, Austria), Franz Berger (Kopfing, Austria), Yelitza Leon-Vargas (Merida, Venzuela), C.Vairappan (Kota Kinabalu, Malaysia), Reinaldo Vargas (Santiago, Chile).

By analysing existing and gathering new data from inventories of freshwater lichens in Central Europe and worldwide a catalogue of criteria will be achieved which will help to understand diversity patterns of Freshwater lichens and identify priority areas for conservation. By revisions of historical herbarium specimens, development of a database for distribution data from several European Herbaria and comparison of reconstructed and revised historic inventories with results from recent and future fieldwork an estimation of the rate of change in different localities and regions of Central Europe is aimed and compared with existing assumptions on the species loss and conservation needs for amphibious lichens.

Lichens as bioindicators in forested ecosystems

Department of Life Sciences: P Wolseley, H Thüs, P Eggleton,

External collaborators: N Sanderson (Southampton, UK), D Carpenter (UK), A Scobie (Port of Spain, Trinidad), G Weerakoon (Colombo, Sri Lanka), U Jayalal (Royal Botanical Garden Peradeniya, Sri Lanka), H. Döring (Kew Gardens), R Lücking, T Lumbsch (Field Museum, Chicago, USA), A.Tehler (Stockholm, Sweden)

Based on data from standardised randomised sampling we are analysing the structure of epiphytic forest lichen communities and their response to natural and anthropogenic influences in temperate and tropical areas. Results of these studies are the identification of bio-indicators for various aspects of environmental health (e.g. climatic conditions, air quality and habitat continuity), updated checklists and recommendations for the management of lichen diversity. Collaboration with colleagues focussing on molecular taxonomy will allow us to investigate the systematic position of new species and re-define the delimitation of critical taxa found during these inventories and barcode their genetic diversity.
