Současný pohled na evoluci chobotnatců Současná systematika chobotnatců není kompletně odvozena od jejich fylogeneze, rekonstruované pomocí kladistických metod. Diskutované skupiny tak mnohdy nepředstavují monofyletické skupiny. Přestože jsou taxonomické kategorie matoucí (např. Laurin 2005), jsem do jisté míry nucen je používat. Některým skupinám úrovně stále přiřazeny nebyly a zde této skutečnosti není přisuzován žádný význam. V této rešerši jsem se zaměřil hlavně na poznatky, které následovaly po vydání knihy; The Proboscidea: Evolution and Paleoecology of Elephants and Their Relatives, od Shoshaniho a Tassyho (1996). Chobotnatci jsou součástí skupiny Tethytheria společně s anthracobunidy, sirénami a desmostylidy (Shoshani 1998; Shoshani & Tassy 1996; 2005; Gheerbrant & Tassy 2009). Základní klasifikace sestává ze dvou skupin. Ze skupiny Plesielephantiformes, do které patří čeledě Numidotheriidae, Barytheriidae a Deinotheridae a ze skupiny Elephantiformes, do které patří čeledě Palaeomastodontidae, Phiomiidae, Mammutida, Gomphotheriidae, tetralofodontní gomfotéria, Stegodontidae a Elephantidae (Shoshani & Marchant 2001; Shoshani & Tassy 2005; Gheerbrant & Tassy 2009). -
Bryozoan Studies 2019
BRYOZOAN STUDIES 2019 Edited by Patrick Wyse Jackson & Kamil Zágoršek Czech Geological Survey 1 BRYOZOAN STUDIES 2019 2 Dedication This volume is dedicated with deep gratitude to Paul Taylor. Throughout his career Paul has worked at the Natural History Museum, London which he joined soon after completing post-doctoral studies in Swansea which in turn followed his completion of a PhD in Durham. Paul’s research interests are polymatic within the sphere of bryozoology – he has studied fossil bryozoans from all of the geological periods, and modern bryozoans from all oceanic basins. His interests include taxonomy, biodiversity, skeletal structure, ecology, evolution, history to name a few subject areas; in fact there are probably none in bryozoology that have not been the subject of his many publications. His office in the Natural History Museum quickly became a magnet for visiting bryozoological colleagues whom he always welcomed: he has always been highly encouraging of the research efforts of others, quick to collaborate, and generous with advice and information. A long-standing member of the International Bryozoology Association, Paul presided over the conference held in Boone in 2007. 3 BRYOZOAN STUDIES 2019 Contents Kamil Zágoršek and Patrick N.

Isthminia Panamensis, a New Fossil Inioid (Mammalia, Cetacea) from the Chagres Formation of Panama and the Evolution of ‘River Dolphins’ in the Americas
Isthminia panamensis, a new fossil inioid (Mammalia, Cetacea) from the Chagres Formation of Panama and the evolution of ‘river dolphins’ in the Americas Nicholas D. Pyenson1,2, Jorge Velez-Juarbe´ 3,4, Carolina S. Gutstein1,5, Holly Little1, Dioselina Vigil6 and Aaron O’Dea6 1 Department of Paleobiology, National Museum of Natural History, Smithsonian Institution, Washington, DC, USA 2 Departments of Mammalogy and Paleontology, Burke Museum of Natural History and Culture, Seattle, WA, USA 3 Department of Mammalogy, Natural History Museum of Los Angeles County, Los Angeles, CA, USA 4 Florida Museum of Natural History, University of Florida, Gainesville, FL, USA 5 Comision´ de Patrimonio Natural, Consejo de Monumentos Nacionales, Santiago, Chile 6 Smithsonian Tropical Research Institute, Balboa, Republic of Panama ABSTRACT In contrast to dominant mode of ecological transition in the evolution of marine mammals, different lineages of toothed whales (Odontoceti) have repeatedly invaded freshwater ecosystems during the Cenozoic era. The so-called ‘river dolphins’ are now recognized as independent lineages that converged on similar morphological specializations (e.g., longirostry). In South America, the two endemic ‘river dolphin’ lineages form a clade (Inioidea), with closely related fossil inioids from marine rock units in the South Pacific and North Atlantic oceans. Here we describe a new genus and species of fossil inioid, Isthminia panamensis, gen. et sp. nov. from the late Miocene of Panama. The type and only known specimen consists of a partial skull, mandibles, isolated teeth, a right scapula, and carpal elements recovered from Submitted 27 April 2015 the Pina˜ Facies of the Chagres Formation, along the Caribbean coast of Panama. -

S1. List of taxa included in the disparity analysis and the phylogenetic alysis, with main references. Taxa in bold are included in the phylogenetic analysis; taxa also indicated by * are included only in the phylogenetic analysis and not in the disparity analysis. Three unpublished arborescent taxa were included on the basis that they showed additional anatomical diversity. 1 Callixylon trunk from the Late Devonian of Marrocco showing large sclerotic nests in pith; 2 Axis from the late Tournaisian of Algeria, previously figured in Galtier (1988), and Galtier & Meyer-Berthaud (2006); 3 Trunk from the late Viséan of Australia. All these specimens and corresponding slides are currently kept in the Paleobotanical collections, Service des Collections, Université Montpellier II, France, under the specimen numbers 600/2/3, JC874 and YB1-2.

2004 Bark Beetles
BARK BEETLE CONDITIONS NORTHERN REGION 2004 Ken Gibson USDA Forest Service Northern Region Forest Health Protection Missoula Field Office December 2004 BARK BEETLE CONDITIONS Northern Region 2004 REGIONAL SUMMARY Although late fall has turned out to be atypically dry, most of the Region received above normal amounts of precipitation during calendar year 2004. Most of Montana, and especially the eastern portions, have not completely broken out of the 4- to 5-year drought; however, growing conditions for most bark beetle hosts improved markedly throughout the Region. Despite improved conditions, long-term drought affects are not easily overcome. Too, many bark beetle species are at extremely high levels and will not respond to improved host conditions for a year or so. Those latter two factors combined to result in an increase in infested area by most bark beetle species across the Region. Unfortunately, less-than-optimal weather conditions late in the season prevented aerial survey of all beetle-infested areas. Approximately 85% of the forested portions of the 24 reporting areas were flown. While some areas appeared to be less impacted, for most of the Region, and particularly Montana; both aerial and ground-collected data showed still- increasing bark beetle infestations for most species. Mountain pine beetle-infested areas increased in many locations surveyed; however, in some locations, intensity of beetle-caused mortality is declining due to host depletion. Decreases in infested area recorded on the Lolo National Forest (NF), however, is a reflection of the amount of area flown—not necessarily an indication that the outbreak, overall, is waning. In total, considerably more infested acres were recorded in 2004 than in 2003; despite some heavily infested areas having not been flown. -
