The fish genera Gasterosteus, Hucho, Oxynoemacheilus, Salmo, and Schizothorax are examples of these groups among vertebrates, and the genera Magnibursatus (Trematoda), Margaritifera, Potomida, Microcondylaea, Leguminaia, Unio (Mollusca), and Phagocata (Planaria), among invertebrates. There is reason to believe that their ancestors spread to Europe through the Paratethys (or the proto-Paratethys basin that preceded it), where intense speciation took place and new genera of aquatic organisms arose. Some of the forms that originated in the Paratethys colonized the Mediterranean, and overwhelming data indicate that Citation: Artamonova, V.S.; Bolotov, representatives of the genera Salmo, Caspiomyzon, and Ecrobia migrated during the Miocene from I.N.; Vinarski, M.V.; Makhrov, A.A.

Received: 6 February 2014; in revised form: 24 March 2014 / Accepted: 27 March 2014 / Published: 15 April 2014 Abstract: Planarians are a group of free-living platyhelminths (triclads) best-known largely due to long-standing regeneration and pattern formation research. However, the group’s diversity and evolutionary history has been mostly overlooked. A few taxonomists have focused on certain groups, resulting in the description of many species and the establishment of higher-level groups within the Tricladida. However, the scarcity of morphological features precludes inference of phylogenetic relationships among these taxa. The incorporation of molecular markers to study their diversity and phylogenetic relationships has facilitated disentangling many conundrums related to planarians and even allowed their use as phylogeographic model organisms. Here, we present some case examples ranging from delimiting species in an integrative style, and barcoding them, to analysing their evolutionary history on a lower scale to infer processes affecting biodiversity origin, or on a higher scale to understand the genus level or even higher relationships. In many cases, these studies have allowed proposing better classifications and resulted in taxonomical changes.

In his neighborhood, he has observed: * Coyotes * Gray "Desert" Fox * Red Fox, and their dens & pups * Jackrabbits and Cottontail rabbits in area, but not on Preserve * Norway Rats, in association with restaurants * "Meadow Mice" * Quail, but not for a long time * Ringneck Snakes [= Diadophis punctatus ] * Rattlesnakes: observed by "old-timers" Jack spoke with in past; still on PV * Toads, in his yard, which were mainly active at night; many became traffic victims * Lizards; commonly seen on walls, etc., in neighborhood.

  • Revised List of the North American Freshwater Planarians (Platyhelminthes: Tricladida: Paludicola)
    Revised List of the North American Freshwater Planarians (Platyhelminthes: Tricladida: Paludicola) ROMAN KENK SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 476 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review.
