Lichen: from genome to ecosystem in a changing world 5I-O (5I-O7) Submission ID: <strong>IAL</strong>0304-00001 LICHENS, BRYOPHYTES AND CLIMATE CHANGE (LBCC) UTILIZING SYMBIOTA SOFTWARE Nash T. H. 1 , Gries C. 2 , Gilbert E. 3 1 Dept. of Botany, University of Wisconsin, Madison, Wisconcin, United States 2 Center for Limnology, University of Wisconsin, Madison, Wisconcin, United States 3 Global Institute of Sustainability, Arizona State University, Tempe, Arizona, United States SYMBIOTA software has been used to create along with other thematic nodes the portals: The Consortium of North American Lichen Herbaria (CNALH, http://symbiota.org/nalichens/) and The Consortium of North American Bryophyte Herbaria (CNABH, http://symbiota.org/bryophytes/index.php). Among other functions, the portals together provide access now to ca. 1.6 million collection records of lichens and bryophytes. Through new funding from the US National Science Foundation, ca. 2.3 million additional specimens will be databased from Canada, Mexico and the USA. Both groups of organisms are dominant components of arctic and subarctic ecosystems and occur extensively in boreal and other temperate to tropical ecosystems. The two portals will provide unparalleled information on distribution patterns both historically and from the present forward. For georeferenced specimens, maps can be readily generated. As such, they will provide a major tool for assessing climate change across North America. In addition, in collaboration with LIAS (LIchenizedAScomycetes) we are developing on-line keys, a prototype of which is available for the greater Sonoran Desert region for over 1,800 species. The keys are being expanded to include known arctic species. The functionality of SYMBIOTA will be demonstrated. 66

In this context, an extensive taxon sampling within the Teloschistales with more loci (especially nuclear protein-coding genes) were needed to confront the current taxonomic delimitations and to improve our understanding of evolutionary trends within this order. The present study assessed this issue using maximum likelihood and Bayesian analyses with complementary bootstrap support values and posterior probabilities based on seven loci using a supermatrix approach, and including protein-coding genes RPB1 and RPB2 apart from nuclear and mitochondrial ribosomal loci. Although the progressive addition of taxa with missing data did not dramatically affect the loss of support and resolution, the monophyly of the Teloschistales in the current sense was inconsistent, depending on the loci-taxa combination analyzed. Based on these results we propose a new, but provisional, classification for the re-circumscribed orders Caliciales and Teloschistales. We report here that the family Brigantiaeaceae and Sipmaniella are members of the Teloschistales in a strict sense. The position of CIoplaca and Josefpoeltia within the Teloschistaceae is confirmed by molecular phylogenetics. Within the Teloschistales, one lineage led to the diversification of the mostly epiphytic crustose Brigantiaeaceae and Letrouitiaceae, with a circumpacific center of diversity and found mostly in the tropics. The other main lineage led to another epiphytic crustose family, mostly tropical, and with an Australasian center of diversity – the Megalosporaceae – which is sister to the mainly rock-inhabiting, cosmopolitan, and species rich Teloschistaceae, with a diversity of growth habits ranging from crustose to fruticose. Additionally, we are presenting a comprehensive phylogeny for the family Teloschistaceae with new loci selected from AFToL2, and a first exploration of the evolution of phenotypic traits and an in-depth characterization for a major taxonomic redelimitation of genera within this family. 67 4A-O
