XIV OPTIMA Meeting, Palermo (Italy), 9-15 September 2013 Insights into the morphological and molecular signals of Californian and Mediterranean populations of Orthotrichum acuminatum LARA F. 1 , VIGALONDO B. 1 , DRAPER I. 1 ; VALCARCEL V. 1 , GARILLETI R. 2 , MAZIMPAKA V. 1 1 Dept. de Biología (Botánica), Facultad de Ciencias, Universidad Autónoma de Madrid, Madrid, Spain. 2 Dept. de Botánica, Facultad de Farmacia, Universidad de Valencia, Valencia, Spain. E-mail: ricardo.garilleti@uv.es Orthotrichum acuminatum H. Philib. is an epiphytic moss known from the Mediterranean basin. In recent years, some populations of mosses morphologically similar to O. acuminatum have been located in southern California, mainly in mountain areas. To establish the identity of these new Californian populations and to test if this is another example of the Madrean-Tethyan disjunction, we have combined a deep morphological study with molecular techniques. Although used plastidial markers (rps4, trnL and atpB-rbcl) do not resolve completely the phylogeny of the studied samples, the obtained results reveal that Californian and Mediterranean samples of O. acuminatum constitute a monophyletic group, closely related to O. speciosum. However, quantitative characters reveal significant differentiation between Californian and Mediterranean specimens of O. acuminatum. Interestingly, the level of morphological differentiation between California and the Mediterranean is similar to the one detected within the Mediterranean basin. We conclude that samples from California belong to O.acuminatum, which results to present a remarkable morphological variability within its amphi-atlantic distribution. More analyses are needed to infer the origin of this Madrean-Tethyan disjunction and to resolve the phylogeny of O. acuminatum group within the Orhotrichum genus. 129
XIV OPTIMA Meeting, Palermo (Italy), 9-15 September 2013 Karyological study of plants from maritime dunes of W. Peloponnisos LIVERI E. 1 , BAREKA P. 2 , KAMARI G. 1 1 Botanical Institute, Section of Plant Biology, Department of Biology, University of Patras, Patras, Greece. E-mail: eleni-liveri@hotmail.com 2 Laboratory of Systematic Botany, Agricultural University of Athens, Athens, Greece. The importance of maritime sand dunes, as providing home to a multitude of both flora and fauna species has been acknowledged in recent years and thus they are regarded as priority habitats for conservation in the European Union. Sandy beaches in Greece have a very characteristic vegetation of mostly perennial herbs. Most of them have a wide distribution along the Mediterranean and Atlantic coasts. However, just a few local endemic species have been recorded. As part of the dissertation of the first author, some interesting plants of maritime sands of W. Peloponnisos were karyologically examined (e.g. Cakile maritima Scop., Centaurea seridis subsp. sonchifolia (L.) Greuter, Dorycnium hirsutum (L.) Ser., Pancratium maritimum L.). The chromosome number and the karyotype analysis for the studied taxa are given, along with notes on their morphology, ecology and geographical distribution. 130
