Premise of the study: Although some species of Characeae, known as stoneworts, can be found on every continent except Antarctica, many species and some genera have limited geographic distributions.

Description
Summary:Premise of the study: Although some species of Characeae, known as stoneworts, can be found on every continent except Antarctica, many species and some genera have limited geographic distributions. The genus Lychnothamnus, represented by a single extant species L. barbatus, was known only from scattered localities in Europe and Australasia until it was recently discovered in North America. Methods: Morphological identifications were made from specimens collected in Minnesota and Wisconsin, U.S.A. DNA sequences were obtained for three plastid-encoded genes (atpB, psbC, rbcL) from seven putative Lychnothamnus samples from two states in the U.S.A. Distribution and abundance were estimated in each lake using point intercept surveys where surveyors sampled aquatic vegetation. Key results: Fourteen lakes in Wisconsin and two lakes in Minnesota, U.S.A., were found to harbor Lychnothamnus barbatus. These represent the first report of this rare charophycean extant in the New World. The North American specimens ... : Karol_etal_threegene_alignment.nexThree plastid gene alignment for the Characeae including Lychnothamnus barbatus from the New World.Karol_etal_3gene.nexKarol_etal_threegene_phylogeny.pdfBayesian inference three gene phylogeny for the Characeae including Lychnothamnus barbatus from the New World.Karol_etal_3gene_phylogeny.pdf ...
