Lagostina, E./ Andreev, M./ Printzen, C. 2017: [Poster:] Sexuality, clonality and dispersal in two Antarctic lichens. - At: Frankfurt am Main, Conference: Geobiodiversity : 10.13140/RG.2.2.29019.05929. [RLL List # 250 / Rec.# 39600]
Abstract: The ability to separate similar species is of crucial importance for studies in population and conservation genetics. Lichens, symbioses between fungi and one or more photosynthetic organisms, are the most important primary producers in Antarctic terrestrial habitats. The two common lichens Usnea antarctica and U. aurantiacoatra have traditionally been separated based on their reproductive mode: U. antarctica forms soredia containing both symbiotic partners while U. aurantiacoatra displays sexual reproduction. Previous molecular analysis based on ITS and RPB1 genes did not find evidence to reliably split the two taxa. It has thus been suggested to treat them as a single species. As part of ongoing projects on the population structure of Antarctic lichens we present here evidence from microsatellite data clearly supporting the distinction between both species. These findings have an impact on sampling design for population genetic studies and the development of conservation strategies.
