Past Climate Changes, Population Dynamics and the Origin of Bison in Europe Diyendo Massilani1†, Silvia Guimaraes1†, Jean-Philip Brugal2,3, E

BMC Biology (2016) 14:93 DOI 10.1186/s12915-016-0317-7 RESEARCHARTICLE Open Access Past climate changes, population dynamics and the origin of Bison in Europe Diyendo Massilani1†, Silvia Guimaraes1†, Jean-Philip Brugal2,3, E.

Spasskaya13, Hans-Peter Uerpmann14, Thierry Grange1*† and Eva-Maria Geigl1*† Abstract Background: Climatic and environmental fluctuations as well as anthropogenic pressure have led to the extinction of much of Europe’s megafauna. The European bison or wisent (Bison bonasus), one of the last wild European large mammals, narrowly escaped extinction at the onset of the 20th century owing to hunting and habitat fragmentation. Little is known, however, about its origin, evolutionary history and population dynamics during the Pleistocene. Results: Through ancient DNA analysis we show that the emblematic European bison has experienced several waves of population expansion, contraction, and extinction during the last 50,000 years in Europe, culminating in a major reduction of genetic diversity during the Holocene. Fifty-seven complete and partial ancient mitogenomes from throughout Europe, the Caucasus, and Siberia reveal that three populations of wisent (Bison bonasus)and steppe bison (B. priscus) alternately occupied Western Europe, correlating with climate-induced environmental changes. The Late Pleistocene European steppe bison originated from northern Eurasia, whereas the modern wisent population emerged from a refuge in the southern Caucasus after the last glacial maximum. A population overlap during a transition period is reflected in ca. 36,000-year-old paintings in the French Chauvet cave. -
The Endoskeletal Origin of the Turtle Carapace
ARTICLE Received 7 Dec 2012 | Accepted 3 Jun 2013 | Published 9 Jul 2013 DOI: 10.1038/ncomms3107 OPEN The endoskeletal origin of the turtle carapace Tatsuya Hirasawa1, Hiroshi Nagashima2 & Shigeru Kuratani1 The turtle body plan, with its solid shell, deviates radically from those of other tetrapods. The dorsal part of the turtle shell, or the carapace, consists mainly of costal and neural bony plates, which are continuous with the underlying thoracic ribs and vertebrae, respectively. Because of their superficial position, the evolutionary origins of these costo-neural elements have long remained elusive. Here we show, through comparative morphological and embryological analyses, that the major part of the carapace is derived purely from endos- keletal ribs. We examine turtle embryos and find that the costal and neural plates develop not within the dermis, but within deeper connective tissue where the rib and intercostal muscle anlagen develop. We also examine the fossils of an outgroup of turtles to confirm that the structure equivalent to the turtle carapace developed independently of the true osteoderm. Our results highlight the hitherto unravelled evolutionary course of the turtle shell. 1 Laboratory for Evolutionary Morphology, RIKEN Center for Developmental Biology, Kobe 650-0047, Japan. 2 Division of Gross Anatomy and Morphogenesis, Department of Regenerative and Transplant Medicine, Niigata University, Niigata 951-8510, Japan.

The Dermochelyoid turtle, Protostega gigas, was first described by Professor E. D. Cope in Proc. Amer. Phil. Soc., 1-871, page 172, and again in the same publication in 1872, page 403. In 1875, m n ^ s ''Cretaceous Vertebrata," pp. 99-113, pis. IX-XIII, the same writer more fully described and illustrated the structure of this remarkable reptile. The materials which were in Professor Cope's hands consisted of a number of vertebrae, ten ribs, some marginal bones, certain por- tions of the skull, some limb bones, and some large plates. Of the lat- ter there were what the describer regarded as two entire and parts of one or two others. These plates he considered as belonging to the carapace, and this was supposed to be free from the ribs, as the pecu- liar carapace otDermochelys is free from the ribs of that turtle. -

ZOOLOGY Exploring the Biodiversity of Colorado and Theworld
CHAPTER 4 — ZOOLOGY Exploring the Biodiversity of Colorado and the World CHAPTER 4 ZOOLOGY Exploring the Biodiversity of Colorado and the World Jeffrey T. Stephenson, Before the Museum Paula E. Cushing, The first collections of specimens that make up what is now the Denver John R. Demboski, and Museum of Nature & Science were actually established well before the Frank-T. Krell founding of the institution in 1900, the selection of a board of trustees, or the construction of a building to house and exhibit the specimens. Edwin Carter (1830–1900) (Fig. 4.1) collected Colorado birds and mammals from the 1860s through the 1890s. Born in New York in 1830, Carter arrived in Colorado in 1859 hoping to make it rich in the goldfields, but he soon became interested in the region’s natural history. He learned hide tanning and, as his prospects for hitting the mother lode faded, he earned his living selling buckskin clothing that he handcrafted. Carter supplemented these earnings by mar- keting foodstuffs and other provisions to the growing population of successful and (mostly) unsuccessful prospectors flooding the region. His interest in nature turned to concern as he observed dwindling numbers of mammals and birds, owing largely to habitat destruction and overhunting. Period photographs of the area’s mining district show a landscape largely denuded of vegetation. By the 1870s, Carter noted that many animal species were becoming scarce. The state’s forests were being devastated, ranches and farms were replacing open prairie, and some species, including the last native bison in Colorado, were on the verge of extirpation or extinction. -

Prova Organoléptica Com Carnes Bubalinas E Bovinas De Animais Criados Nas Pastagens De Várzeas Da Amazônia Central
PROVA ORGANOLÉPTICA COM CARNES BUBALINAS E BOVINAS DE ANIMAIS CRIADOS NAS PASTAGENS DE VÁRZEAS DA AMAZÔNIA CENTRAL Jörg J. OHLY1 RESUMO—Devido ao domínio do mercado e do consumo pela came bovina, aos hábitos de consumo tradicionais e à qualidade inferior da oferta de carne bubalina (Bubalus bubalis), esta ainda é rejeitada ou pelo menos é considerada de qualidade inferior em muitos países, assim como também no Brasil. Para verificar se há uma clara rejeição a carne bubalina devido a de critérios tais como sabor, aroma, maciez, textura, suculência, cor da gordura, cor da carne e aceitação geral, foi realizada uma prova organoléptica na cidade de Manaus-AM, Brasil. Em um churrasco tradicional foram comparados cortes habituais de carne bubalina e bovina. Os resultados mostraram que ambos os tipos de carne tinham uma qualidade semelhante e que são infundados os preconceitos existentes a respeito da carne bubalina. Palavras-chave: Came bubalina, carne bovina, prova organoléptica, várzea, Amazônia, Brasil Organoleptic Assessment of Water Buffalo Meat and Beef of Animals Raised on Central Amazonian Floodplain Pastures ABSTRACT—Owing to the dominance of the beef market, traditional consumer habits and the often inferior quality of water buffalo (Bubalus bubalis) meat offered, the meat of this species is still rejected in many countries, like it is the case of Brazil, or at least considered as low-grade meat. In order to find out whether or not there is a distinct rejection of water buffalo meat on account of criteria such as taste, flavour, tenderness, texture, juiciness, colour of fat, colour of meat and general acceptability, an organoleptic test was organized in the city of Manaus-AM, Brazil. -
Harlan's Lost Mosasaur Snout Rediscovered

Email: [email protected] Manuscript received: January 2005; accepted: March 2005 Abstract The lost snout of Richard Harlan's specimen of Mosasaurus missouriensis has been rediscovered in the vertebrate palaeontology collections of the Museum national d'Histoire Naturelle (MNHN) in Paris, France. The specimen (MNHN 9587) bears the handwritten description, 'Amerique du Nord. Par M. Harlan.', which translated reads, 'North America. By/From Mr. Harlan'. Accession information indicates the specimen was a gift to the museum prior to 1860 and was likely gifted from Harlan's estate after his death. We examine the available history of the collection of the specimen present a description of the rediscovered snout, and demonstrate conclusively the conspecificity of M. maximiliani Goldfuss, 1845 and M. missouriensis (Harlan, 1834a) by providing a revised diagnosis of the taxon.

Fossil Chimaeroid Remains (Chondrichthyes: Holocephali) from Williamsburg County, South Carolina, Usa
Paludicola 8(1):37-48 September 2010 © by the Rochester Institute of Vertebrate Paleontology FOSSIL CHIMAEROID REMAINS (CHONDRICHTHYES: HOLOCEPHALI) FROM WILLIAMSBURG COUNTY, SOUTH CAROLINA, USA David J. Cicimurri Campbell Geology Museum, Clemson University, Clemson, South Carolina 29634 <[email protected]> ABSTRACT Three fossil holocephalian tooth plates have been recovered in Kingstree, Williamsburg County, South Carolina. All of the fossils were collected from a lag deposit containing a temporally mixed vertebrate assemblage. Two specimens, an incomplete left mandibular tooth plate and an incomplete left palatine tooth plate, are Edaphodon and compare favorably to E. mirificus. The third specimen is an incomplete and highly abraded right mandibular tooth plate from a very young individual that is questionably referred to Edaphodon. The tooth plates were associated with Cretaceous shark and dinosaur teeth, Paleocene shark and crocodilian teeth and turtle bones, and Plio-Pleistocene shark teeth and terrestrial mammal remains. The source of the Cretaceous fossils is arguably from Maastrichtian (late Cretaceous) strata (i.e., Peedee or Steel Creek formations), whereas Paleocene fossils are likely derived from the Danian (lower Paleocene) Rhems Formation. These fossils were probably concentrated together during Plio- Pleistocene sea level highstand, at which time the younger vertebrate material was deposited. INTRODUCTION Fossils from Clapp Creek came to the attention of Rudy Mancke (then Curator of Natural History at the Some of the geologic history of the South South Carolina State Museum) in the mid 1980s, and Carolina Coastal Plain is preserved as a complex soon thereafter he alerted Bruce Lampright (then of stratigraphic sequence that is far from completely Coastal Carolina University) to the fossil deposits to be understood.
