Our eutherians from Europe and North America comprising estimations reveal that Leptictidium was a very agile ani- species with highly specialized postcranial features mal with agility score values (4.6 and 5.5, respectively) including elongated hind limbs. Among them, the Euro- comparable to Macroscelidea and extant bipedal saltatory pean Leptictidium was probably a bipedal runner or jum- placentals. Leptictis and Palaeictops have lower agility per. Because the semicircular canals of the inner ear are scores (3.4 to 4.1), which correspond to the more gener- involved in detecting angular acceleration of the head, their alized types of locomotion (e.g., terrestrial, cursorial) of morphometry can be used as a proxy to elucidate the agility most extant mammals.

Socioeconomic and Ecological Aspects of Field Rat Control in Tropical and Subtropical Countries Bans Kurylas
SOCIOECONOMIC AND ECOLOGICAL ASPECTS OF FIELD RAT CONTROL IN TROPICAL AND SUBTROPICAL COUNTRIES BANS KURYLAS. Thai-German Rodent Control Project. German Agency for Technical Cooperation (GTZ), P.O. Box 9-34, Bangkok. Thailand. ABSTRACT: The vital question. as to the cause of the pennanent increase in field rat populations throughout most tropical and subtropical areas. has been the subject of researchers and fielcM!en during the past years, in the hope of finding an answer to this problem. Man has made his way through history wherein he was gradually able to renounce nature and establish his own man-made cultural frame. Unlike other marrmals. man has no natural instincts to guide him through life. Brain and spirit have to compensate for lack of. physical capabilities and instincts. Man was forced to change his natural surroundings in order to serve his special and ever-growing needs . Survival meant not only using nature but more so changing it in order to develop his culture. The field rat has become man's "cultural treader"! Myomorpha is the largest suborder of the Order Rodentia. Of the 1700 rodents known to man. more than 1100 belong to this group. The greater part of the Myomorpha species are found within two families, which are Cricetidae with about 567 species and Muridae with about 475 species. Most of these rodents live either in trees or under the ground. They rarely collide with man's interest. Only a few rodent species have become "field rats" and seem to dwell in and utilize man's cultural steppe. Some species have even become cosmopolitan and are found in Europe. -

New Large Leptictid Insectivore from the Late Paleogene of South Dakota, USA
New large leptictid insectivore from the Late Paleogene of South Dakota, USA TJ MEEHAN and LARRY D. MARTIN Meehan, T.J. and Martin, L.D. 2012. New large leptictid insectivore from the Late Paleogene of South Dakota, USA. Acta Palaeontologica Polonica 57 (3): 509–518. From a skull and mandible, we describe a new genus and species of a primitive insectivore (Mammalia: Insectivora: Leptictida: Leptictidae). Its large body size and higher−crowned teeth indicate a different feeding ecology from other leptictid insectivores. With evidence of some heavy, flat wear on the molariform teeth, its shift in diet was likely to greater herbivory. Unlike the narrow snout of Blacktops, this new leptictid retains a broad snout, suggesting that small verte− brates were still important dietary components. The specimen was collected from the floodplain deposits of the lower or middle White River Group of South Dakota, which represent the latest Eocene to earliest Oligocene (Chadronian and Orellan North American Land Mammal “Ages”). Key words: Mammalia, Leptictidae, Leptictis, Megaleptictis, Eocene, Oligocene, White River Group, South Dakota, North America.

The lack of an identifiable intermediate host species for the proximal animal ancestor of SARS-CoV-2 and the distance (~1500 km) from Wuhan to Yunnan province, where the closest evolutionary related coronaviruses circulating in horseshoe bats have been identified, is fueling speculation on the natural origins of SARS-CoV-2. Here we analyse SARS-CoV-2’s related horseshoe bat and pangolin Sarbecoviruses and confirm Rhinolophus affinis continues to be the likely reservoir species as its host range extends across Central and Southern China. This would explain the bat Sarbecovirus recombinants in the West and East China, trafficked pangolin infections and bat Sarbecovirus recombinants linked to Southern China. Recent ecological disturbances as a result of changes in meat consumption could then explain SARS-CoV-2 transmission to humans through direct or indirect contact with the reservoir wildlife, and subsequent emergence towards Hubei in Central China. -

We show that spikes from Guangdong Pangolin-CoVs, closely related to SARS-CoV-2, bind strongly to human and pangolin ACE2 receptors. We also report the cryo-EM structure of a Pangolin-CoV spike protein and show it adopts a fully-closed conformation and that, aside from the Receptor-Binding Domain, it resembles the spike of a bat coronavirus RaTG13 more than that of SARS-CoV-2. 1 Structural Biology of Disease Processes Laboratory, Francis Crick Institute, NW1 1AT, London, UK. 2 Precision Medicine Center, The Seventh Affiliated Hospital, Sun Yat-sen University, Shenzhen, Guangdong, China. 3 Structural Biology of Cells and Viruses Laboratory, Francis Crick Institute, NW1 1AT, London, UK. 4 Structural Biology Science Technology Platform, Francis Crick Institute, NW1 1AT, London, UK. 5These authors contributed equally: Antoni G. ✉ Wrobel, Donald J.

Appendix Lagomorph Species: Geographical Distribution and Conservation Status
Appendix Lagomorph Species: Geographical Distribution and Conservation Status PAULO C. ALVES1* AND KLAUS HACKLÄNDER2 Lagomorph taxonomy is traditionally controversy, and as a consequence the number of species varies according to different publications. Although this can be due to the conservative characteristic of some morphological and genetic traits, like general shape and number of chromosomes, the scarce knowledge on several species is probably the main reason for this controversy. Also, some species have been discovered only recently, and from others we miss any information since they have been first described (mainly in pikas). We struggled with this difficulty during the work on this book, and decide to include a list of lagomorph species (Table 1). As a reference, we used the recent list published by Hoffmann and Smith (2005) in the “Mammals of the world” (Wilson and Reeder, 2005). However, to make an updated list, we include some significant published data (Friedmann and Daly 2004) and the contribu- tions and comments of some lagomorph specialist, namely Andrew Smith, John Litvaitis, Terrence Robinson, Andrew Smith, Franz Suchentrunk, and from the Mexican lagomorph association, AMCELA. We also include sum- mary information about the geographical range of all species and the current IUCN conservation status. Inevitably, this list still contains some incorrect information. However, a permanently updated lagomorph list will be pro- vided via the World Lagomorph Society (www.worldlagomorphsociety.org). 1 CIBIO, Centro de Investigaça˜o em Biodiversidade e Recursos Genéticos and Faculdade de Ciˆencias, Universidade do Porto, Campus Agrário de Vaira˜o 4485-661 – Vaira˜o, Portugal 2 Institute of Wildlife Biology and Game Management, University of Natural Resources and Applied Life Sciences, Gregor-Mendel-Str. -

Durden Department of Biology, Georgia Southern University, Statesboro, GA 30458 Will K. Reeves Colorado State University, C. P. Gillette Museum of Arthropod Diversity, Fort Collins, CO 80521 Abstract: We are just now beginning to learn about the ectoparasites and helminth parasites of some owls of Oklahoma. Some recent contributions from our lab have attempted to help fill a previous void in that information. Here, we report, four taxa of ectoparasites and five helminth parasites from three species of owls in Oklahoma. They include two species of chewing lice (Strigiphilus syrnii and Kurodeia magna), two species of hippoboscid flies (Icosta americana and Ornithoica vicina), a trematode (Strigea elegans) and a cestode (Paruterina candelabraria) from barred owls (Strix varia), and three nematodes, Porrocaecum depressum from an eastern screech owl (Megascops asio), Capillaria sp. eggs from S. varia, and Capillaria tenuissima from a great horned owl (Bubo virginianus). With the exception of Capillaria sp. eggs and I. americana, all represent new state records for Oklahoma and extend our knowledge of the parasitic biota of owls of the state. to opportunistically examine raptors from the Introduction state and document new geographic records for their parasites in Oklahoma. Over 455 species of birds have been reported Methods from Oklahoma and several are species of raptors or birds of prey that make up an important Between January 2018 and September 2019, portion of the avian fauna of the state (Sutton three owls were found dead on the road in 1967; Baumgartner and Baumgartner 1992).
